Objective: To determine the sex prevalence of lower limb varicose networks fed by reflux of the great saphenous vein (GSV), anterior accessory saphenous vein (AASV), and small saphenous vein singularly or in combination., Methods: We scanned by the means of the same color Doppler ultrasound protocol 3000 lower limbs in 1500 consecutive patients, affected by symptomatic chronic venous insufficiency from 2013 to 2023. Limbs with normal venous function, incomplete scans, or that were affected by post-thrombotic syndrome, pelvic reflux, isolated perforator reflux, venous malformation, phlebolymphedema and Clinical, Etiological, Anatomical, Pathophysiological clinical class C5 and C6 were excluded from the final analysis., Results: Overall, 1072 patients-252 (23.5%) males and 820 (76.5%) females (P < .0001) matched for age (P = .692)-were included in the study for a total of 1956 limbs affected by primary chronic venous insufficiency, clinical class C2 to C4. The main finding was the significant prevalence of varicose networks fed by reflux of the AASV alone (odds ratio [OR], 1.96; 95% confidence interval [CI], 1.26-3.06; P = .001) or combined with GSV (OR, 1.84; 95% CI, 1.34-2.52; P = .0002) in females. In contrast, GSV insufficiency alone was significantly prevalent in males (OR, 0.54; 95% CI, 0.43-0.68; P < .0001). No significant sex differences regarding SSV reflux were detected. Moreover, we considered the presence of competent terminal valve (TV+) at the level of the saphenofemoral junction, which resulted more significantly present in female (OR, 1.57; 95% CI, 1.12-2.19; P = .0083); to the contrary incompetent terminal valve (TV-) was more common in males (OR, 0.64; 95% CI, 0.46-0.89; P = .0083). Finally, considering reflux in the AASV territory in the presence of a TV+, a strong prevalence in females was detected (OR, 2.28; 95% CI, 1.48-3.52; P = .0002), whereas males developed reflux along the GSV when a concomitant TV- was present (OR, 0.62; 95% CI, 0.41-0.94; P = .0244)., Conclusions: The analysis of the lower limb varicose networks highlights that reflux along the AASV alone, in presence of a TV+ at the junction or coupled with GSV insufficiency, is more prevalent in females. In contrast, GSV resulted the main trunk feeding varicose veins in males, in particular when a TV- was detected. Our findings suggest that females could be more prone to developing varicose veins with an ascending mechanism, whereas in males the descending one seems to be more common., Competing Interests: Disclosures None., (Copyright © 2024 The Author(s).

Background and Objectives: Chronic venous insufficiency negatively affects the quality of life and reduces the job performance of nurses, who are important components of the healthcare system. The aim of this study was to assess the risk factors of venous insufficiency according to demographic characteristics among nurses working at a foundation university hospital. Materials and Methods: This study used an analytical cross-sectional approach. The sample consisted of 100 nurses working at a foundation university hospital in a metropolitan city of Turkey. Data were collected using a demographic characteristics form, VEINESQOL/Sym, and a CEAP classification form. The condition of varicose veins among the nurses was diagnosed by a cardiovascular surgeon using Doppler ultrasonography. Results: The prevalence of chronic venous insufficiency (CVI) among nurses was 65%, with 48% at a C1 level according to the CEAP classification. CVI was higher among those with chronic diseases ( p = 0.027) and those who had pregnancy ( p = 0.021). In addition, the risk of CVI (+) was 7.68 times higher among those aged older than 26.5 years and 36.14 times higher for women ( p < 0.001). A 0.9-fold increase in the risk of CVI (+) among nurses produced a one-unit decrease in venous-insufficiency-related quality of life ( p = 0.006, OR = 0.94, 95% CI:(0.896-0.982)). Conclusions: The prevalence of CVI among nurses was found to be high, especially among women, those with chronic diseases, and pregnant individuals. In this context, it is recommended to implement risk screening and prevention education programs for CVI among nurses.

Objectives: The aim of this study was to understand the prevalence of chronic venous disease (CVD) of lower limbs in young men at high-altitude in Xizang, and to provide prevention measures., Methods: The convenient sampling method was used to conduct a questionnaire survey among males aged 18 to 40 above an altitude of 3000 meters in Xizang in April 2023. The contents of the questionnaire included basic information, symptoms of CVD of lower limbs, protection status and training needs. Multivariate logistic regression model was calculated to evaluate the risk factors for CVD., Results: A total of 350 survey questionnaires were received, and 326 valid samples were collected. The prevalence of CVD of lower limbs (C1-C6) was 37.42% (95%CI: 32.17%-42.68%), the ratio of C0 to C5 were 62.58%, 27.30%, 3.07%, 4.60%, 2.15% and 0.31%, respectively, no one reached C6. The top three symptoms of CVD were lower limb fatigue (18.10%), heaviness (15.34%) and pain (13.19%). 46.01% of respondents were unaware of CVD, and 12.88% of respondents did not have any protective measures of CVD. Multivariate logistic regression showed that age (OR = 1.076, 95%CI: 1.018-1.137, p = .009), preference for spicy food (OR = 1.747, 95%CI: 1.083-2.818, p = .022), unbalanced diet (OR = 1.877, 95%CI: 1.049-3.358, p = .034) and physical exercise (OR 0.610, 95%CI: 0.377-0.986, p = .044) were the independent risk factors for CVD., Conclusions: This study provided data on the prevalence of CVD in young men at high-altitude and the risk factors for CVD. The findings of this study may facilitate the development of individualized clinical assessments and targeted prevention programs., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: This review article provides an updated review of a relatively common pathology with various manifestations. Superficial venous diseases (SVDs) are a broad spectrum of venous vascular disease that predominantly affects the body's lower extremities. The most serious manifestation of this disease includes varicose veins, chronic venous insufficiency, stasis dermatitis, venous ulcers, superficial venous thrombosis, reticular veins, and spider telangiectasias., Methods: The anatomy, pathophysiology, and risk factors of SVD were discussed during this review. The risk factors for developing SVD were related to race, age, sex, lifestyle, and certain genetic conditions as well as comorbid deep vein thrombosis. Various classification systems were listed, focusing on the most common one-the revised Clinical-Etiology-Anatomy-Pathophysiology classification. The clinical features including history and physical examination findings elicited in SVD were outlined., Results: Imaging modalities utilized in SVD were highlighted. Duplex ultrasound is the first line in evaluating SVD but magnetic resonance imaging and computed tomography venography, plethysmography, and conventional venography are feasible options in the event of an ambiguous venous duplex ultrasound study. Treatment options highlighted in this review ranged from conservative treatment with compression stockings, which could be primary or adjunctive to pharmacologic topical and systemic agents such as azelaic acid, diuretics, plant extracts, medical foods, nonsteroidal anti-inflammatory drugs, anticoagulants and skin substitutes for different stages of SVD. Interventional treatment modalities include thermal ablative techniques like radiofrequency ablationss, endovenous laser ablation, endovenous steam ablation, and endovenous microwave ablation as well as nonthermal strategies such as the Varithena (polidocanol microfoam) sclerotherapy, VenaSeal (cyanoacrylate) ablation, and Endovenous mechanochemical ablation. Surgical treatments are also available and include debridement, vein ligation, stripping, and skin grafting., Conclusions: SVDs are prevalent and have varied manifestations predominantly in the lower extremities. Several studies highlight the growing clinical and financial burden of these diseases. This review provides an update on the pathophysiology, classification, clinical features, and imaging findings as well as the conservative, pharmacological, and interventional treatment options indicated for different SVD pathologies. It aims to expedite the timely deployment of therapies geared toward reducing the significant morbidity associated with SVD especially varicose veins, venous ulcers, and venous insufficiency, to improve the quality of life of these patients and prevent complications., (Published by Elsevier Inc.)

Chronic venous disease (CVD) is highly prevalent in the general population and encompasses a range of pathological and hemodynamic changes in the veins of the lower extremities. These alterations give rise to a variety of symptoms, with more severe forms resulting in venous ulceration, which causes morbidity and high socioeconomic burden. The origins and underlying mechanisms of CVD are intricate and multifaceted, involving environmental factors, genetics, hormonal factors, and immunological factors that bring about structural and functional alterations in the venous system. This review offers the latest insights into the epidemiology, pathophysiology, and risk factors of CVD, aiming to provide a comprehensive overview of the current state of knowledge. Furthermore, the diagnostic approach for CVD is highlighted and current diagnostic tools are described., Competing Interests: The authors declare that they have no conflict of interest., (Thieme.

Objectives: To determine the demographics, outcomes, and healthcare utilization of patients with chronic venous insufficiency-associated lymphedema (CVI-LED) and the prevalence of lymphedema-specific therapy use after venous intervention., Methods: The IBM MarketScan Commercial and Medicare Claims Databases were examined for patients with CVI-LED. Patient demographics and the use of lymphedema-specific therapy before and after venous intervention were collected., Results: Of 85,601 LED patients identified, 8,406 also had a diagnosis of CVI. In the CVI-LED group, 1051 underwent endovenous ablation or venous stent placement. The use of lymphedema-specific therapy before and after venous intervention was 52% and 39%, respectively ( p < .05). The mean time of initiation of LED-specific therapy following venous intervention was 265 days after ablation and 347 days after stent placement., Conclusion: Treating venous hypertension improves certain venous-related signs and symptoms of CVI. However, a significant proportion of patients have persistent edema which may reflect underlying, sub-optimally treated LED., Competing Interests: Declaration of conflicting interestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: MG: none.

Introduction: Chronic venous disease is a global public health problem, with high morbidity and economic distress. There is scarcity of data on this disease in sub-Saharan Africa., Methods: We conducted the first population-based study over a period of 20 months from 1st February 2020 to 30th September 2021 in the 10 regions of Cameroon. A stratify sampling method was chose to select study site. Socio-demographic data, personal and family history, anthropometric parameters, clinical signs, illustrative images, CEAP (Clinical-Etiological-Anatomical-Pathophysiological) classification revised in 2004, VCSS (venous Clinical Severity Score) and risk factor assessment score were used to construct the survey form. Chi-squared test and Fischer exact test were used to compare the prevalence of chronic venous disease across different potential risk factors (sex, age category, previous history of deep vein thrombosis, hypertension, diabetes, smoking status, obesity). Simple and multiple logistic regression models were used to obtain crude and adjusted odds ratio for risk factors associated with chronic venous insufficiency. Statistical analyses were done with R version 4.2 for Linux and the threshold for statistical significance was 0.05., Results: A total of 6578 participants were included in the study, with a mean age of 41.09 ± 16.02 years with female predominance (54.3%). The prevalence of chronic venous disease was 21.8% (95% CI: 20.8-22.9) and the prevalence of chronic venous insufficiency (C3-C6) was 7.02% ( n = 462). Night cramps (43.2%), oedema (21.7%), lower limbs pain (20.4%) mostly worsens by walking and heavy legs (16.2%) were more common symptoms. The mean total venous clinical severity score was 0.69 ± 1.76 and this score had a significant positive correlation with C classification ( p < .001). In the multivariate analysis, the following factors were independently associated with CVD: Male gender (aOR: 1.27; 95%CI: 1.04-1.56; p = .021), retired people (aOR: 46.9; 95% CI: 12.6-174.5; p < .001), hypertension (aOR: 289.5; 95%CI: 169.69-493.1; p < .001), diabetes (aOR: 2.19; 95% CI: 1.21-3.96; p = .009), obesity (aOR: 10.22; 95%CI: 7.67-13.62; p < .001). Smoking appears as a protective factor (aOR: 0.18; 95%CI: 0.10-0.30; p < .001)., Conclusion: Chronic venous disease is frequent in Cameroon and main traditional cardiovascular risk factors are associated to this condition. Systematic screening of the CVD in these specific groups could reduce the burden of the disease and its economic impact., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: The aim of this publication is to demonstrate similarities and differences in the association of risk factors with the prevalence of different manifestations of chronic venous disease (CVD), like varicose veins (VV), venous oedema (C3) and severe chronic venous insufficiency (CVI) in the population-based cross-sectional Bonn Vein Study 1 (BVS). Patients and methods: In the BVS 1 between 13.11.2000 and 15.3.2002, 3.072 participants, 1350 men and 1722 women, from a simple random sample of the general population of the city of Bonn and two rural townships aged 18-79 years were included. The overall response proportion was 59%. All participants answered a standardized questionnaire including information about socio-economic data, lifestyle, physical activity, medical history, and quality of life. Venous investigations were performed clinically and by a standardized duplex examination by trained investigators. The CEAP classification in the version of 1996 was used to classify the findings. Logistic regression models were performed for the association of possible risk factors with VV, venous edema (C3) and severe CVI (C4-C6). The predictive risk (PR) describes the association of the diseases and the possible influencing factors. Results: VV, venous oedema (C3) and severe CVI (C4-C6) have common risk factors like higher age, number of pregnancies, family history of VV and overweight or obesity. Female gender is significantly associated with VV and C3 but not with severe CVI (C4-C6). High blood pressure and urban living are only associated with C3 and C4-C6 disease whereas prolonged sitting is associated with C3 and lower social class with C4-C6 exclusively. Discussion: In many epidemiological studies risk factors were associated with chronic venous disorders in general. Our data show that VV, venous edema and severe CVI may have different risk profiles. Venous edema is more often associated with arterial hypertension and sedentary lifestyle whereas lower social class seems to be a risk factor for severe CVI including venous ulcers. Conclusions: The differences in the association of risk factors to VV, venous edema and severe CVI should be considered if prevention and treatment of chronic venous diseases are planned. As examples, compression stockings could be proposed in sitting profession to prevent oedema, VV patients with risk factors like obesity might benefit from early treatment for VV and obesity. More longitudinal evaluation of risk factors is necessary to evaluate the true risk profile of CVD.

Background: The aim of our study was to explore the characteristics of the arterial risk factors and ankle-brachial index (ABI) in patients with lower extremity chronic venous disease (LECVD)., Methods: A total of 2642 subjects were employed in our study. The lifestyle and clinical data were collected. The history of vascular diseases contained coronary artery disease, stroke, hypertension, and diabetes. ABI low than 0.9 was considered as lower extremity artery disease (LEAD). A series of blood indicators were measured., Results: Patients with ABI low than 0.9 belonged to the group of LEAD. Age, smoking, drinking, hypertension, diabetes mellitus, lipid-lowering drug, antidiabetic, total protein, total protein, triglyceride, low-density lipoprotein cholesterol, glycosylated hemoglobin and homocysteine were the common risk factors shared by LEAD and LECVD (P<0.05). The prevalence of LEAD in patients with LECVD was higher than those without LECVD (P<0.05). In Pearson correlation analysis, LECVD was related to LEAD (P<0.05). Before and after adjusted shared factors, as the performance of the logistic regression models, LEAD was an independent risk factor for the prevalence of LECVD (OR=2.937, 95% CI: [1.956, 4.411], P<0.001)., Conclusions: Our study demonstrated that an ABI lower than 0.9 is an independent risk factor for LECVD.

Objective: To comparatively evaluate performances of tablet-based versus paper-based Venous Insufficiency Epidemiologic and Economic Study-Quality of Life/Symptom (VEINES-QOL/Sym) questionnaire., Methods: We prospectively evaluated 78 consecutive patients who completed tablet-based and paper-based VEINES-QOL/Sym questionnaires and compared their scores, completion time, data entry time, and ease of use. We used Student's t-test and Wilcoxon test for quantitative variables, Bland-Altman test and kappa coefficient for agreement between questionnaires and patients, respectively. Spearman's correlation coefficient was used to assess correlations., Results: Most participants (83.3%) found it easier to use the tablet device. Less time was needed to complete the tablet-based (median, 4.75; IQR, 3-7 min) than the paper-based (median, 8.3; IQR, 6.3-11.3 min) questionnaire ( p < .001). Better educated patients took less time to complete paper-based ( p = .003) and tablet-based ( p = .001) questionnaires and considered the latter easier to use ( p = .010)., Conclusions: The tablet-based VEINES-QOL/Sym proved to be an easy-to-use and time-saving tool., Competing Interests: Declaration of conflicting interestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: The first author is the developer of the Veines application.

Background: Diabetes, hypertension, and smoking are well-recognized risk factors for peripheral artery disease (PAD), but little is known of their impact on chronic venous insufficiency (CVI). This study evaluates these factors in patients undergoing iliac vein stenting (IVS) for CVI., Methods: A registry of 708 patients who underwent IVS from August 2011 to June 2021 was retrospectively analyzed. Symptoms were quantified using venous clinical severity score (VCSS) and CEAP classification. Both major and minor reinterventions were recorded. Logistic regression models were used to determine the unadjusted and adjusted odds ratio of any reintervention. Log-rank test was used to assess differences in reintervention-free survival., Results: The prevalence of hypertension was 51.1% (N = 362), diabetes was 23.0% (N = 163), and smoking was 22.2% (N = 157). Patients with diabetes (3.6 vs. 3.4; P = 0.062), hypertension (3.6 vs. 3.3; P < 0.001), and smoking (3.7 vs. 3.4; P = 0.003) had higher CEAP scores than those without these comorbidities. Improvement in VCSS composite scores showed no differences postoperatively (diabetes: P = 0.513; hypertension: P = 0.053; smoking: P = 0.608), at 1-year follow-up (diabetes: P = 0.666; hypertension: P = 0.681; smoking: P = 0.745), or at 5-year follow-up (diabetes: P = 0.525; hypertension: P = 0.953; smoking: P = 0.146). Diabetes (P = 0.454), smoking (P = 0.355), and hypertension (P = 0.727) were not associated with increased odds of major reintervention. Log-rank test similarly showed no differences in reintervention-free survival for major or minor reoperations between those with and without diabetes (P = 0.79), hypertension (P = 0.14), and smoking (P = 0.80)., Conclusions: Diabetes, hypertension, and smoking were prevalent among CVI patients, but unlike in PAD patients, they had little to no impact on long-term outcomes or reinterventions after IVS., (Copyright © 2023 Elsevier Inc.

Chronic venous insufficiency (CVI) causes severe symptoms and complications in the general population, but the prevalence, related risk factors, and treatment of CVI are unknown among nurses. The demographics and occupational factors of nurses from a university hospital were collected by questionnaires, and the presentation of CVI was confirmed by the specialist vascular surgeons. A total of 1606 participants were enrolled, and the prevalence of CVI was 7.5%. After multivariate adjustment, CVI was positively related to deep venous thrombosis history (OR 6.44, 95% CI 2.73-15.22), increased standing time (OR 2.21, 95% CI 1.20-4.10), and increased time in night shift rotation (OR 2.01, 95% CI 1.29-3.14). CVI was negatively related to oral contraceptives (OR .43, 95% CI .21-.87). Of the participants, 72.5% with CVI received compression therapy. For them, wearing compression stockings with a pressure of >20 mmHg or for >4 h/day significantly increased the rate of symptom relief, while the length of compression stockings made no difference. Thus, it was beneficial for nurses to spend less time standing and shorten their time in night shift rotation. Wearing compression stockings with sufficient pressure and for enough time was recommended for CVI symptom relief., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objective: The relationship between physical activity and lower limb veins is complex. If a sedentary lifestyle is considered to be negative on lower limb veins, specific information on physical activity varicose vein volume is sparse, especially the effect of high physical activity volume. The main objective of the VARISPORT study was to evaluate lower limb veins (clinically, morphologically, and haemodynamically) and chronic venous disease symptoms in subjects exposed to high physical activity volume compared with a group of non-exposed subjects., Methods: A cross sectional study compared a group of high exercise training volume volunteers (more than eight hours of uninterrupted vigorous intensity physical activity per week for more than six months: high physical activity volume group, HPAV group) with a volunteer control group matched for age, sex, and body mass index. Clinical examination was performed to determine the Clinical, Etiological, Anatomical, Pathophysiological (CEAP) classification of each subject and the Carpentier score was used to assess symptoms related to possible chronic venous disease. Duplex ultrasonography was used to assess vein diameters and reflux in the deep and superficial veins., Results: One hundred and nineteen subjects were included in each group. The lower limb veins (deep and superficial) were significantly more dilated in the HPAV group. More reflux was found in the great saphenous veins and non-saphenous veins in the HPAV group. High physical activity volume was associated with a higher frequency of visible varicose veins (stage C2 of the CEAP classification), odds ratio 3.37 (95% confidence interval 1.66 - 7.25) without impact on functional discomfort (44 subjects with a Carpentier score ≥ 1 in each group)., Conclusion: The VARISPORT study reported an increase in the calibre of the lower limb veins without impact on functional discomfort. Further studies are needed to determine whether these athletic veins are truly pathological varicose veins or simply an adaptation to high physical activity volumes., (Copyright © 2023 European Society for Vascular Surgery.

Chronic venous disease (CVD) occurs because of structural or functional disturbances to the venous system of the lower limbs. Signs and symptoms include leg pain, swelling, varicose veins, and skin changes, with venous ulceration ultimately occurring in severe disease. To assess the prevalence of CVD among health care workers, a scoping review of existing publications exploring the prevalence of CVD among health care workers was conducted in July 2022. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used. A total of 15 papers met the inclusion criteria and these formed the basis of the review. Among health care workers, the mean prevalence of CVD was 58.5% and the mean prevalence for varicose veins was 22.1%. There is an increased prevalence of CVD in health care workers when compared with the general population. Therefore, there is a need for early diagnosis and the use of preventative measures to protect health care workers from CVD and varicose vein development., (© 2023 The Authors.

Objective: To investigate the association between chronic pelvic pain (CPP) and pelvic vein incompetence (PVI) or pelvic varices., Design: Case-control study., Setting: Gynaecology and vascular surgery services in two teaching hospitals in north-west England., Sample: A total of 328 premenopausal women (aged 18-54 years), comprising 164 women with CPP and 164 matched controls with no history of CPP., Methods: Symptom and quality-of-life questionnaires and transvaginal duplex ultrasound for PVI and pelvic varices., Main Outcome Measures: Venous reflux of >0.7 s in the ovarian or internal iliac veins (primary outcome) and presence of pelvic varices (secondary outcome). Statistical analysis compared the prevalence of PVI between women with and without CPP using the two-sided chi-square test. Logistic regression was used to compare the odds of having PVI and pelvic varices between women with and without CPP., Results: Pelvic vein incompetence was found on transvaginal duplex ultrasound in 101/162 (62%) women with CPP, compared with 30/164 (19%) asymptomatic controls (OR 6.79, 95% CI 4.11-11.47, p < 0.001). Forty-three of 164 (27%) women with CPP had pelvic varices compared with three of 164 (2%) asymptomatic women (OR 18.9, 95% CI 5.73-62.7, p < 0.001)., Conclusions: There was a significant association between PVI, as detected by transvaginal duplex imaging, and CPP. Pelvic varices were strongly associated with CPP and were infrequently seen in control patients. These results justify further evaluation of PVI and its treatment in well-designed research., (© 2023 The Authors.

The use of drug therapies in patients with chronic venous disease (CVD) remains a topic of debate regarding safety, compliance, and effectiveness. Although the beneficial effects of molecules like diosmin have been established in patients with chronic venous insufficiency (CVI) of C3-C6 classes, the evidence for its use in C0-C1 patients is not well documented. This report aims to describe and analyze the positive impact of a new diosmin-based drug therapy on a population of C0-C1 patients in terms of relief of venous symptoms.

Introduction: Chronic venous disease (CVD) is characterized by venous hypertension and stasis, which occur because of valvular incompetence and/or venous outflow obstruction. This study aimed to investigate the relationship between CVD clinical presentation and duplex ultrasonography findings in a Thai patient population., Method: This cross-sectional study examined patients diagnosed with CVD at the Chulabhorn Hospital Vascular Clinic (Bangkok, Thailand) between December 1, 2018 and October 1, 2021. Patient data was obtained from the medical records and review of lower limb venous ultrasonography studies. Patients were assessed using the Clinical, Etiological, Anatomical, and Pathological (CEAP) classification of venous disorders: mild-to-moderate CVD was defined as C1 to C3 and severe CVD was defined as C4 to C6., Results: Overall, 260 CVD patients were analyzed (60 men and 200 women). More than 75% of the patients were women and more than 80% had bilateral lower limb involvement. Factors associated with severe CVD were older age, female sex, high body mass index, hypertension, diabetes mellitus, and history of deep venous thrombosis. The most common CEAP classification was C2 (38.8%), followed by C1 (33.85%), C4 (12.2%), C3 (9.23%), C6 (3.46%), and C5 (2.31%). Two-thirds of the patients had great saphenous vein reflux and nearly half had perforator vein reflux. Perforator reflux and small saphenous vein reflux were significantly associated with severe CVD (P < 0.001 and P = 0.028, respectively). Higher number of venous systems involved was significantly associated with severe CVD (P = 0.005). Reflux time of the great saphenous vein correlated with severe CVD and VCSS (P = 0.026 and P = 0.037, respectively). Mean diameters of the superficial vein, perforator vein, and deep vein and reflux times of the perforator and deep veins were not significantly associated with severe CVD., Conclusion: The major risk factors for severe CVD are older age, female sex, high body mass index, hypertension, diabetes mellitus, and history of deep venous thrombosis. The most common CEAP classification was C2 (39%). Great saphenous vein reflux was the most common type of reflux in our study population. Increasing number of venous systems involved increased the risk of severe CVD. The presence of perforator vein reflux and small saphenous vein reflux also increased the risk of severe CVD. Reflux time of the great saphenous vein correlated with severe CVD and venous clinical severity score., Competing Interests: Declaration of competing interest None., (Copyright © 2023 Asian Surgical Association and Taiwan Robotic Surgery Association.

The full spectrum of venous disease poses a significant burden on individuals and health-care systems globally. Venous disease can lead to a wide range of symptoms based on the level of disease and underlying pathology. In general, underlying pathologies are due to nonthrombotic (reflux/obstructive) and thrombotic causes. Most conditions are a sequela of the long-term effects of chronic venous insufficiency, deep vein thrombosis (DVT), or nonthrombotic deep vein obstruction. The prevalence of venous disease is substantial, impacting the quality of life of a considerable proportion of the adult population. Untreated and progressive lower extremity venous disease can lead to venous ulceration and other complications. Additionally, poorly recognized and poorly understood venous conditions of the abdomen and pelvis leave many patients "orphaned" in health-care systems that lack expertise in complex venous conditions. Addressing the burden and breadth of venous disease requires comprehensive management approaches, early diagnosis, appropriate treatment interventions, and provider and patient education. Multidisciplinary collaborations and further research are essential to enhance our understanding, develop innovative therapies, and improve patient outcomes in the field of venous disease. In this paper, we highlight the importance of multidisciplinary collaboration and our journey to building an institutional venous team, as well as lessons learned., Competing Interests: Disclosure Dr Harth reports receiving consulting fees from Boston Scientific, Medtronic, and Inari; and speaker fees from Boston Scientific, Medtronic, Inari, Cook, GE, and Philips.

Background and Objectives : Chronic venous disease (CVD) is a widespread clinical condition that is very common in western countries in the adult general population with a wide range of clinical manifestations, such as varicose veins (VVs) that in certain circumstances may complicate with rupture and subsequent bleeding that may even be fatal. The aim of this study is to evaluate risk factors for bleeding VVs. Materials and Methods : This is a retrospective study conducted in patients with CVD complicating with bleeding of VVs over a 4-year period (2019-2022). A random sample, for the same 4-year period and with a 3:1 ratio, was selected from other CVD patients without VVs bleeding that served as the control group. Results : From a global population of 1048 patients with CVD over a 4-year period, a total of 33 patients (3.15%) with VVs bleeding were selected. A group of 99 patients without VVs bleeding were randomly selected from the total population of 1048 patients with CVD. Findings of this study showed that advanced clinical stage of CVD (i.e., C4b stage), advanced age, living alone, suffering from cardiovascular co-morbidity (i.e., hypertension and CHF), assuming certain drugs that act on blood coagulation (i.e., aspirin, anticoagulants), assuming psychotropic medication, having particular venous reflux patterns (i.e., below-knee GSV reflux, non-saphenous veins reflux, Cockett's perforators reflux), and not having been assessed and treated previously for CVD (i.e., with VADs, CT, or surgery) may predispose a high risk for bleeding VVs. Conclusions : Bleeding VVs may be a life-threatening complications of CVD patients, and monitoring risk factors found in this study and others that, hopefully, may be discovered in the future through further focused research will help to reduce the impact of this problem in this patient population.

Objective: The aim of the present study was to investigate the prevalence and predictors of combined >50% iliocaval venous obstruction (ICVO) and superficial venous reflux (SVR) in patients with chronic venous insufficiency (CVI) with a healed (C5) or an active (C6) venous leg ulcer (VLU)., Methods: We conducted a retrospective review of prospectively collected data from patients with CVI with CEAP (Clinical, Etiology, Anatomy, Pathophysiology) class C5 (healed ulcer) or C6 (active ulcer) with SVR who had been treated at our institution from February 2017 to January 2018. The demographic, clinical, and surgical data and duplex ultrasound and computed tomography venography findings were collected. We used OsiriX MD, version 2.9, software (Pixmeo SARL, Bernex, Switzerland) to measure the vein diameter via multiplanar reconstruction. The prevalence of combined >50% ICVO and SVR was evaluated, and univariate and multivariate analyses were performed to identify the independent predictors of >50% ICVO in patients with CVI and SVR., Results: A total of 79 limbs from 67 patients were enrolled. The mean age was 59.82 ± 12.86 years, the mean body mass index was 28.68 ± 6.41 kg/m 2 , and 41.8% were men. The prevalence of >50% ICVO in the patients with SVR was 31.6%. Univariate analysis showed a history of deep vein thrombosis (DVT) in the affected leg (P = .001), a VLU in the left leg (P = .033), a history of a recurrent VLU (P = .038), and reversed flow in the superficial epigastric vein (P = .004) were significantly associated with >50% ICVO in patients with CVI and SVR. Multivariate analysis revealed a history of DVT in the affected leg (adjusted odds ratio [aOR], 8.31; 95% confidence interval [CI], 2.29-30.19; P = .001), a VLU in the left leg (aOR, 3.95; 95% CI, 1.18-13.19; P = .026), and a history of a recurrent VLU (aOR, 3.08; 95% CI, 1.02-9.32; P = .047) to be independently associated with combined >50% ICVO and SVR in patients with CVI., Conclusions: The prevalence of combined >50% ICVO and SVR in patients with CVI and CEAP C5 or C6 was 31.6%. The independent predictors of combined >50% ICVO and SVR in those with CVI were a history of DVT in the affected leg, a VLU in the left leg, and recurrent VLUs., (Copyright © 2023 The Authors.

Objective: The study was aimed at the identification of hemodynamic and neurobiological factors for the development of chronic pelvic pain (CPP) in patients with pelvic venous disorder (PeVD) using ultrasound, radionuclide, and enzyme immunoassay methods., Methods: This cohort study included 110 consecutive patients with PeVD and 20 healthy controls. Seventy patients with PeVD had symptoms (CPP in 100% of cases, discomfort in hypogastrium, dyspareunia, vulvar varices, and dysuria), and 40 were asymptomatic. Patients underwent clinical examination, duplex ultrasound study of the pelvic veins and lower extremities, and single-photon emission computed tomography of the pelvic veins with in vivo labeled red blood cells. The prevalence, duration, severity, and pattern of reflux in the pelvic veins, as well as the severity of pelvic venous congestion, were evaluated. Healthy controls underwent only clinical and duplex ultrasound examination. All 130 patients were assessed using enzyme immunoassays to determine plasma levels of calcitonin gene-related peptide (CGRP) and substance P (SP)., Results: Symptomatic patients with PeVD had a higher prevalence of reflux in the ovarian veins (OVs) than asymptomatic ones (45.7% vs 10%, respectively; P = .001) and a greater reflux duration (4.1 ± 1.7 seconds vs 1.4 ± 0.3 seconds; P = .002), although no differences in the OV diameter were found. Similar results were obtained when comparing the diameters of the parametrial veins (PVs) and the duration of reflux in them. Type II/III reflux (greater than 2 seconds) was identified in 41.4% of symptomatic and in only 5% of asymptomatic patients (P = .001). Among patients with CPP, 24.2% had a combined reflux in the OVs, PVs, and uterine veins, and 45.7% had a combined reflux in the OVs and PVs, whereas 90% of patients without CPP had only an isolated reflux in the PVs. The pelvic venous congestion was moderate or severe in 95.7% of patients with CPP and in only 15% patients without CPP (P = .001). In patients with PeVD, the presence of CPP was associated with higher levels of CGRP and SP compared with asymptomatic patients (CGRP: 0.48 ± 0.06 vs 0.19 ± 0.02 ng/mL, respectively, P = .001; SP: 0.38 ± 0.08 vs 0.13 ± 0.03 ng/mL, P = .001)., Conclusions: In patients with PeVD, significant hemodynamic and neurobiological factors for the CPP development were found to be reflux in the pelvic veins greater than 2 seconds, involvement of several venous collectors, and increased plasma levels of CGRP and SP., (Copyright © 2023 Society for Vascular Surgery.

Background: Chronic venous disorders are common, with varicose veins occurring in ∼40% of the population. Venous leg ulcers affect 1% to 2% of the population, with the prevalence increasing ≤4% for those aged >65 years. Both conditions are expensive and together are responsible for ≤2% of the annual healthcare budget expenditure of Western societies. The ESCHAR (effect of surgery and compression on healing and recurrence) and EVRA (early venous reflux ablation) trials demonstrated that surgical correction of superficial venous reflux reduced ulcer recurrence, resulted in faster healing times (EVRA), and was proved cost-effective. Largescale data regarding patients with chronic venous leg ulcers presenting to venous centers with treatable superficial venous insufficiency has not been previously reported. Our study was designed to evaluate the percentage of patients with leg ulcers presenting to dedicated vein centers who were found to have surgically correctable superficial venous insufficiency., Methods: The American Vein & Lymphatic Society Patient Reported Outcome Venous Registry began collecting data in 2014 and is one of two national registries focused on chronic venous disorders. The database was queried first for the presence of an ulcer using the CEAP (clinical, etiologic, anatomic, pathophysiologic) classification (C6 status). These de-identified data were further correlated by crossing the number of ulcers for the same limb using the revised venous clinical severity score (rVCSS). The demographics, index duplex ultrasound details, and rVCSS features for ulcer duration and compression use were analyzed. Once the presence of an ulcer had been validated by CEAP and rVCSS, the population was divided into groups according to the ultrasound-reported anatomic pathology (eg, normal, reflux, obstruction, reflux plus obstruction). The query was directed toward all patients seeking a venous evaluation at participating centers from January 2018 through January 2022., Results: More than 270,000 unique patient records were reviewed. Of the 270,000 records, 163,027 (60%) had had duplex ultrasound scans available, for 1794 unique patients (1879 limbs), representing 1.1% with a leg wound. Of these patients, 55.4% were men and 44.6% were women. Group S included patients with isolated superficial pathology (n = 1291; 68.7%). Group M included patients with mixed superficial and deep pathology (n = 238; 12.7%). Group D included patients with isolated deep vein pathology (n = 58; 3.1%). Finally, group N included patients with leg wounds but no venous pathology (n = 292; 15.5%). The rVCSSs for groups S and M were significantly higher than those for group N. In group S, the dominant patterns involved the great saphenous vein (GSV) above the knee (54.8%), the small saphenous vein (30.7%), and the anterior accessory GSV (14.4%). The frequency of single, double, and triple axial vein reflux identified 1.45 vessels eligible for ablation treatment per limb. In group M, the dominant patterns involved the GSV above the knee (61.7%), the small saphenous vein (26.2%), and the anterior accessory GSV (12.1%), for 1.52 axial segments per limb. Of the 84.4% of venous ulcer patients, duplex ultrasound analysis revealed that 97% of this large subset had had surgically correctable disease., Conclusions: The American Vein & Lymphatic Society Patient Reported Outcome Venous Registry demonstrated that 85% of the leg wounds in the present study were venous in origin and 97% possessed surgically correctable disease. Our findings support early referral to dedicated vein centers with appropriate venous reflux management as a part of the multidisciplinary team caring for patients with venous leg ulcers., (Copyright © 2023.

Objective: We had observed that some patients with chronic venous insufficiency (CVI) had reported their lower extremity edema was worse during warmer weather. Limited research is available regarding the seasonal variation in lower extremity edema. Patients with CVI were questioned to determine whether they had experienced significant seasonal variation in their lower extremity edema and which factors might be associated with such variation., Methods: Consecutive patients with lower extremity edema were asked whether the edema was worse in the summer or warmer weather. Data was collected between June 2017 and August 2020. A total of 1683 patients (age range, 16-102 years; mean ± standard deviation, 62 ± 14.3 years). Of the 1683 patients, 1157 were female (mean age, 62 ± 14.13 years) and 526 were male (mean age, 62.5 ± 13.82 years). Data were also collected on the presenting symptoms, degree of venous reflux of the great saphenous vein (GSV) reported from the most recent duplex ultrasound, and the season at the time of questioning. For statistical analysis, χ 2 goodness-of-fit tests and one-way analysis of variance tests were used., Results: Of the 1683 patients, 56.6% had reported worsening of their lower extremity edema during warmer weather, including 62.7% of the female patients and 37.3% of the male patients. The female patients had reported significantly more worsening of their lower extremity edema (P = 7.06e-18). Female patient age was associated with whether they had experienced worsening (P = .02), with more younger patients reporting worsening. Male patient age was not associated with whether they had reported worsening (P = .97). No significant differences were found in the degree of presenting symptoms between those who had and had not reported worsening (P = .58). Also, no significant differences were found in the degree of venous reflux between the right (P = .61) and left (P = .89) GSV between those who had and had not reported worsening. The season in which the patients had presented during the study period was associated with whether they had reported worsening edema. The patients who had been questioned in the winter (December, January, February) and summer (June, July, August) had reported more worsening of their edema in the warmer months (P = .008 and P = .0002, respectively). The patients who had been questioned in the spring (March, April, May) and fall (September, October, November) had not reported significantly more worsening of their edema in the warmer months (P = .167 and P = .119, respectively)., Conclusions: Of the 1683 patients surveyed, 56.6% had reported worsened edema in the warmer weather. The women (especially the younger women) in the present study had experienced significant worsening, although the men had not. The degree of GSV venous reflux and severity of the presenting symptoms of the patients was not associated with whether worse edema had been reported. However, the season in which the patients had been questioned was associated with the report of worsening edema. The patients questioned in the coldest and warmest months had reported significantly more worsening. The patients questioned in the milder months had not reported significantly more worsening. These findings suggest that a sex and age bias exists in the seasonal variation of lower extremity edema in patients with CVI., (Copyright © 2023 Society for Vascular Surgery.

Introduction: Venous leg ulcers (VLUs) are the final stage of chronic venous insufficiency. This study aims to characterize the association between cardiovascular diseases and VLU., Methods: A multicentric case-control study analyzed 17,788 patients between 2015 and 2020. Cases were matched (1:2) by age and sex, and odds ratios (OR) were analyzed with conditional logistic regressions adjusted by risk factors., Results: The prevalence of VLU was 15.2%. 2390 cases were analyzed. Diseases found to be associated with VLU were atrial fibrillation (OR, 1.21; 95% CI: 1.03-1.42), pulmonary hypertension (OR, 1.45; 95% CI: 1.06-2.00), right heart failure (OR, 1.27; 95% CI: 1.13-1.43), peripheral artery disease (OR, 2.21; 95% CI: 1.90-2.56), and history of pulmonary embolism (OR, 1.45; 95% CI: 1.06-2.00)., Conclusions: Certain cardiovascular conditions showed an association with VLU. Further studies are warranted to evaluate the effect that treating concomitant cardiovascular diseases might exert on the natural history of venous leg ulcers.

Background: Venous ablation (VA) of the saphenous vein is the most common procedure performed for venous insufficiency. The incidence of concomitant deep venous reflux (DVR) in patients undergoing VA is unknown. Our hypothesis is that patients undergoing saphenous VA with concomitant DVR exhibit a higher clinical, etiology, anatomy, and pathophysiology (CEAP) stage and less relief after VA compared to patients without DVR., Methods: Electronic medical records of patients treated with saphenous VA at a tertiary care center from March 2012 to June 2016 were reviewed. Patients were divided into 2 groups based on presence or absence of DVR on initial ultrasound (US) before saphenous VA. Patient characteristics and outcomes were compared. A telephone survey was conducted to assess long-term symptomatic relief, compliance with compression, and pain medication use. Subgroup analysis of patients with post-thrombotic versus primary DVR was performed., Results: 362 patients underwent 497 ablations, and the incidence of DVR (>1 sec) was 20% (N = 71). Patients with DVR were significantly more likely to be male (46.4% vs. 32.1%, P = 0.021) and of Black race (21.2% vs. 5.5%, P = 0.0001) compared to patients without DVR. Patients with DVR were more likely to have a history of deep vein thrombosis (DVT) (15.1% vs. 7.9%, P = 0.045), but there was no difference in other comorbidities. There was no significant difference in presenting symptoms, CEAP stage, or symptom severity based on numeric rating scale (NRS) (0-10) for pain and swelling. Clinical success of saphenous VA was comparable between the 2 groups, but patients with DVR were more likely to develop endovenous heat-induced thrombosis (EHIT) II-IV (6% vs. 1%, P = 0.002). After a mean follow-up of 26 months, there was still no difference in pain or swelling scores, but patients with DVR were more likely to use compression stockings and used them more frequently. Only 11 of 71 patients with DVR had a history of DVT. Patients with post-thrombotic DVR were significantly older than patients with primary DVR (67.3 vs. 57.2, P = 0.038) and exhibited a trend toward more advanced venous disease (C4-C6: 45.4% vs. 33.3%, P = 0.439)., Conclusions: In this study, 20% of patients undergoing saphenous VA demonstrated DVR, which was more common in Black men. Presence of DVR is associated with increased risk of EHIT after saphenous VA but does not seem to impact disease severity or clinical relief after ablation. Larger studies are needed to understand outcome differences between post-thrombotic and primary DVR., (Copyright © 2023 Elsevier Inc. All rights reserved.)

Objective: The prevalence of lower limb chronic venous insufficiency (CVI) of the deep veins is increasing and presents a significant burden to patients and health care services. To improve the evaluation of interventions it is necessary to standardise their reporting. The aim of this study was to perform a systematic review of the outcomes of interventions delivered to people with CVI of the deep veins as part of the development of a novel core outcome set (COS)., Methods: Following the Core Outcome Measures in Effectiveness Trials (COMET) framework for COS development, a systematic review was conducted to PRISMA guidance. The protocol was preregistered on PROSPERO (CRD42021236795). MEDLINE, Embase, Emcare, CINAHL, and the Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Database of Systematic Reviews and Clinicaltrials.gov were searched from January 2018 to January 2021. Clinical trials and observational studies involving more than 20 participants, reporting outcomes for patients with CVI of the deep veins were eligible. Outcomes were extracted verbatim, condensed into agreed outcome terms and coded into domains using standard COMET taxonomy. Outcome reporting consistency, where outcomes were fully reported throughout the methods and results of their respective articles was also assessed., Results: Some 103 studies were eligible. There were 1183 verbatim outcomes extracted, spanning 22 domains. No outcome was reported unanimously, with the most widely reported outcome of primary patency featuring in 51 articles (<50%). There was a predominant focus on reporting clinical outcomes (n = 963 [81%]), with treatment durability (n = 278 [23%]) and clinical severity (n = 108 [9%]) reported frequently. Life impact outcomes were relatively under-reported (n = 60 [5%]). Outcome reporting consistency was poor, with just 50% of outcomes reported fully., Conclusions: Outcome reporting in studies of people with CVI of the deep veins is currently heterogeneous. Life impact outcomes, which likely reflect patients' priorities are under-reported. This study provides the first step in the development of a COS for people with lower limb CVI of the deep veins., (Copyright © 2022 Society for Vascular Surgery. All rights reserved.)

Objective: To evaluate the incidence of anomalies in the superficial venous system in lower limb., Method: Triplex ultrasonography in clinically suspected cases of acute or chronic venous disease or congenital malformation was performed on 3189 lower limbs in 2000 patients (bilateral in 1189 and unilateral in 811) from Jan 2020 to Dec 2020., Result: (1) Anomalies of great saphenous vein were observed in 496 cases (15.5%), (2) Anomalies of short saphenous vein were observed in 760 cases (23.8%), (3) Anomalies of accessory saphenous veins were seen in 984 (30.88%), 1501 (47%), 1068 (33.5%) and 774 (24.25%) corresponding to the anterior, posterior, lateral systems and posterior accessory vein of leg, respectively., Conclusion: Anomalies of the superficial venous system in lower limb are very common and must be reported in every doppler study. These anomalous veins may be the cause for residual or recurrent disease in chronic venous insufficiency, which warrants further research.

Background and Aims: Few studies have evaluated the correlation between the severity of cutaneous manifestations of chronic venous disease (CVD) of the lower limbs measured by the Clinical, Etiologic, Anatomic and Pathophysiologic classification (CEAP) and the Venous Clinical Severity Score (VCSS) combined, its risk factors, and venous reflux determined by Doppler ultrasonography. The purpose of this study was to compare the clinical severity assessed by CEAP and VCSS with known risk factors for CVD and the severity of venous reflux., Methods: A prospective study was carried out on 250 patients with CVD characterized as C2 to C6 according to the CEAP classification, who attended the departments of Dermatology and Vascular Medicine at the Hospital Privado Universitario de Córdoba from April 2013 to December 2014. Chi-square test, Kruskal-Wallis analysis and multivariate logistic regression analysis were performed to examine the relations between these variables., Results: Risk factors significantly associated with clinical severity included older age, hypertension, obesity, sedentarism, history of soft tissue infection, deep vein thrombosis (DVT), previous ulcer, and family history of venous ulcer. Both scores showed a good correlation between clinical severity and the presence of superficial, deep or perforating venous reflux. Older age, male gender and a history of DVT were significant risk factors for venous reflux in patients with mild disease., Conclusions: In addition to venous reflux, modifiable risk factors such as obesity, sedentarism, and hypertension are associated with CVD severity. Mild cutaneous manifestations may accompany moderate to severe venous reflux, especially in middle-aged or older men with a history of DVT., (Copyright © 2022 AEDV.

Introduction: The prevalence of chronic venous disease (CVD), a common health care problem, is still underestimated. A few previous epidemiologic studies have report Asian patients with this condition in western countries, but not in Asian countries. The aim of this study was to determine risk factors for CVD and its treatment in Thai individuals., Methods: In this cross-sectional study, we collected data of patients with CVD visiting Chulabhorn Hospital Vascular Clinic from 1 December 2018-1 October 2021. We reviewed medical records for patient characteristics, comorbidities, Clinical, Etiology, Anatomy, Pathophysiology (CEAP) categories, Venous Clinical Severity Score (VCSS), ultrasound findings and treatment., Results: The study cohort comprised 260 CVD patients with CVD of mean age 61.92 ± 12.82 years. Almost 80% of participants were female. A history of deep vein thrombosis (DVT) was the strongest risk factor for severe CVD. Other identified risk factors comprised body-mass index (BMI) >30 kg/m 2 , and older age. The most common CEAP categories were C2 (39%) and C1 (33.8%). Superficial venous reflux was the most common location of venous reflux in this study, 67.32% of participants having great saphenous vein reflux and 16.99% small saphenous vein reflux. Only 4.76% of our cohort had both reflux and obstruction. Most of the participants had undergone compression therapy, approximately half of them complying well with wearing of stockings. Nineteen percent of our cohort had undergone sclerotherapy and 14% surgery, which comprised radiofrequency ablation in 97% of them., Conclusion: The major risk factors for severe CVD identified in this study were deep vein thrombosis, body mass index>30 kg/m 2 and older age. The most common CEAP category was C2 (39%). GSV was the most commonly involved venous system. Involvement of numerous venous systems was a risk factor for severe CVD., Competing Interests: The author reports no conflicts of interest in this work., (© 2022 Taengsakul.)

The aim of this study was to identify clinical factors associated with exercise-induced vasculitis (EIV). This study included EIV cases and controls matched for age. Cases included were all members of a hiking club and participated in extended hiking trips. Exercise-induced vasculitis was diagnosed based on clinical signs occurring only after prolonged walks. Chronic venous disease was defined using the Clinical Etiological Anatomical Pathophysiologic classification. This study included 162 hikers: 32 EIV cases and 130 matched controls. Mean age at EIV diagnosis was 47.1 years and 24 (75.0%) of EIV cases were women. Chronic venous disease was present in 19 (57.6%) of EIV cases vs 39 (30.0%) in controls ( P = .001); those with EIV had significantly more saphenous vein insufficiency and C3 venous insufficiency than controls, 85.0 vs 52.6% and 8 (25.0%) vs 13 (10.0%) ( P = .02), respectively. For EIV cases, mean walking distance per hike was significantly higher than for controls ( P = .002). Exercise-induced vasculitis symptoms were typical with rash and/or purpura on the leg in warm conditions. Lesions spontaneously disappear in <10 days. In this study, EIV cases had more chronic venous disease and longer mean walking distances than controls.

Background: This single center prospective randomized study was performed to compare the effect of endovenous laser flush ablation (EVLAf) of the great saphenous vein (GSV) close to the sapheno-femoral junction (SFJ) with a standard ablation (EVLAs) up to two cm distally of the SFJ on reflux in the GSV stump. Patients and methods: Between April 2013 and January 2016, 146 legs in 146 consecutive patients, meeting the inclusion/exclusion criteria, were treated by EVLA. All patients were randomized into 2 groups. In group 1 EVLAf started from the SFJ level, and in group 2 EVLAs started two cm below the SFJ. The primary endpoint was reflux in the GSV stump after 900 days. Secondary endpoints were reflux in the anterior accessory saphenous vein (AASV), proximal clinically recurrent varicose veins related to reflux in the stump and/or the AASV. Results: At day 900, 27 patients were lost to follow-up. Reflux in the stump was detected in 3.6% in group 1 and in 22.2% in group 2 (p<0.05). Reflux in the AASV was present in 7.1% in group 1 and in 17.46% in group 2 (p=0.09). Proximal clinically recurrent varicose veins were observed in 8.9% in group 1 and in 19.1% in group 2 (p=0.12). The greatest diameter of the stump was significantly larger in group 2 (group 1: 0.41 cm, group 2: 0.6 cm, p<0.001). Conclusions: EVLAf is associated with a significantly lower incidence of reflux in the GSV stump, with a trend to a lower incidence of reflux in the AASV and with a lower incidence of proximal recurrent varicose veins after 900 days follow-up compared to EVLAs. EVLAf may improve the clinical recurrence rate after EVLA of the GSV.

Background: Venous hypertension causes many different cutaneous findings such as varicosities, telangiectasia, edema, and pigmentation, dermatitis, and venous ulcers on the skin., Objective: This study aims to investigate the cutaneous signs and symptoms of chronic venous insufficiency (CVI) and to examine their contribution to early diagnosis., Methods: A total of 150 patients were included in the study who applied to the dermatology outpatient clinic and were diagnosed with skin disease related to CVI or had skin findings. Patient's age, gender, complaints, occupation, additional diseases, drug usage, history of prolonged standing and travel, smoking habit, number of pregnancies, history of varicose veins in the family, dermatological diagnosis/findings, and venous Doppler ultrasonography reports were examined retrospectively., Results: 56% of patients were women. Mean age was 56.69 ± 13.6 years. Overall, 82.7% of total patients had at least one skin finding. The most frequent skin findings except varicose veins were insufficiency dermatitis accounted for 32.7% of patients, telangiectasia, and pigmentation which were comprised 25.3%, 19.3% of the total number of patients respectively. In addition to this, 48.7% of patients had itching problems and 32.7% had pain. Moreover, 46% of patients presented superficial vein insufficiency, while 8.7% had deep vein insufficiency. For 47.3% of patients, vein diameter dilation was observed and 11.3% suffered from perforating vein insufficiency. In terms of Clinical-Etiologic-Anatomic-Pathophysiologic (CEAP) classification, scores of 52% of the patients were C3 and lower, while scores of 48% of total patients were C4a and higher., Conclusions: Early diagnosis and treatment of chronic venous insufficiency could prevent further chronic processes such as venous ulceration which is an advanced CVI finding. Thus, assessing the early skin findings might be important to identify the underlying venous insufficiency disease., (© 2021 Wiley Periodicals LLC.)

Background: The effect of iliac vein stenting on ipsilateral limb reflux is unknown and has remained a matter of speculation. It has been suggested that the propensity for reflux might worsen when proximal stenosis is corrected. This could allow for retrograde flow with coughing and the Valsalva maneuver, stressing the valve. We examined this hypothesis by an analysis of the long-term effects of iliac vein stenting on limb reflux using a single-center, retrospective analysis of prospectively collected data., Methods: Reflux data from duplex ultrasound of 1387 limbs in 1228 patients who had undergone iliac vein stenting from 1997 to 2018 were analyzed. Of the 1387 limbs, 632 (46%) had had ipsilateral duplex ultrasound-determined valve reflux before stenting, and 747 limbs (54%) had not had reflux; data were missing for 8 limbs. Reflux status before and after stenting was available for seven individual segments for each limb in the database for analysis (total, 9653 segments). The stented patients were examined for reflux at least annually during the follow-up period (range, 1-26 years). Segmental reflux prevalence was detected using duplex ultrasound. We have referred to this as "duplex reflux" or simply "reflux." Reflux severity was graded using (1) a reflux segmental score, assigning one point each for refluxing segments in the limb; (2) air plethysmography (venous filling index [VFI 90 ]); and (3) ambulatory venous pressure (venous filling time [VFT])., Results: Prestent duplex reflux was present in a combination of superficial, deep, and perforator segments. Reflux prevalence ranged from 7% of deep femoral segments to 51% at the popliteal segment. Post-stent reflux resolution varied from 21% at the femoral vein segment to 58% at the perforator segments. Reflux had completely resolved in 23% of the limbs. New-onset reflux was rare, with a median incidence of 7% for all segments at risk, with cumulative improvement (Kaplan-Meier curve) in reflux severity (segment score, VFI 90 , and VFT) for most limbs. These metrics were unimproved, with residual reflux in only 18%, 11%, and 6% (segment score, VFI 90 , and VFT, respectively) of the limbs at long-term follow-up., Conclusions: Long-term follow-up of limbs after iliac vein stenting has shown that the associated ipsilateral reflux prevalence and severity will improve in most limbs over time., (Copyright © 2022 The Authors.

Objective: The aim of the present study was to evaluate the correlation between incompetent perforator veins (PVs) and venous pigmentation., Methods: A total of 203 limbs of patients with chronic venous disease were studied. The limbs were classified into two groups: C2 group (varicose veins) and C4a group (skin changes with pigmentation). The PVs of the lower legs were examined using Doppler ultrasound. The diameter, reflux duration, and peak velocities were measured and analyzed. The pigmentation area in the lower leg was also studied., Results: Pigmentation in the lower legs was significantly associated with venous insufficiency of the PVs. The prevalence of PVs insufficiency was higher for the C4a patients compared with the C2 patients (96 of 164 [58.3%] vs 4 of 39 [10.3%]; P < .001). The presence of incompetent PVs was associated with an increased risk of pigmentation (OR, 8.977; 95% CI, 2.824-28.537; P < .001). The higher the patients' pigmentation severity (higher VCSS), the greater the prevalence of perforator venous insufficiency (P < .001). The PVs in the areas of pigmentation were larger in diameter, required longer to reach peak velocity, and had higher peak velocities than the PVs in nonpigmented limbs (P < .01 for all). We found a linear relationship between the pigmentation area and the diameter of the PV, reflux time, and peak velocity (r = 0.272, r = 0.172, and r = 0.664, respectively; P < .05)., Conclusions: Incompetent PVs are a significant risk factor for venous pigmentation and, therefore, are potentially suitable for surgical correction., (Copyright © 2022 Society for Vascular Surgery.

Background: Calcifications in the subcutaneous layer (SCL) have been described by radiographic studies of legs with advanced chronic venous disease (CVD). However, SCL calcifications have rarely been included among the CVD-related changes. The aim of the present study was to evaluate the prevalence and morphology of SCL calcifications in legs with CVD of all grades of severity determined by ultrasound., Methods: A total of 500 legs in 250 patients (148 women and 102 men; mean age, 51 years; range, 18-87 years) referred to our vascular clinic for symptoms and signs of CVD were included. After duplex ultrasound evaluation of the deep, superficial, and perforating veins, the skin and SCL were investigated using duplex ultrasound. Those patients with other possible causes of SCL calcification were excluded., Results: Using the C component of the CEAP (clinical, etiologic, anatomic, pathophysiologic) classification, 43 legs were classified as C1, 189 as C2, 34 as C3, 16 as C4A, 45 as C4B or C, 18 as C5, and 16 as C6. Varicose veins were reported in 273 legs, and lipodermatosclerosis in 79 legs. Subcutaneous calcifications were demonstrated in 35 of 361 legs with CVD in two different locations: the wall of superficial varicose veins and in subcutaneous tissue unrelated to the path of the superficial veins. Superficial veins calcifications were found in 12 of 273 legs with varicose veins (4.4%) and were found in older patients with severe varicose vein disease (grade 3 using the venous clinical severity score and disease duration >30 years). Subcutaneous tissue calcifications (STCs) were found in 24 of 95 legs with a more advanced CVD stage (C4A-C6). No STCs were found in legs with a C1, C2, or C3 class., Conclusions: Superficial veins calcifications were found only in the legs with severe and long-lasting varicose veins and seemed to be related to chronic severe inflammation of the venous wall. STCs were independent of the vein wall and were found only in the damaged areas of legs with severe CVD (C4-C6). STCs are possibly related to chronic inflammation of the subcutaneous tissue. Their avulsion from the ulcer bed has been recommended to facilitate ulcer healing and prevent recurrence., (Copyright © 2022 Society for Vascular Surgery. Published by Elsevier Inc.

Introduction: People who inject drugs (PWID) are vulnerable to a range of harms, including vascular conditions such as chronic venous insufficiency (CVI), leg ulcers and deep vein thrombosis (DVT). The extent of vascular conditions has rarely been studied, despite contributing to considerable illness and disability among PWID. We assess the prevalence and associations of vascular conditions in PWID in London, UK., Methods: Survey data from the community-recruited Care and Prevent Study of PWID in London were analysed. Participants were asked about CVI and leg ulcers using pictorial questions, and if they had ever been diagnosed with DVT. Associations between vascular conditions and demographic/drug-use information were explored using univariate and multivariable logistic regression., Results: Among participants (n = 455), the prevalence of CVI, leg ulcers and DVT was 13% (n = 57), 10% (n = 46) and 23% (n = 105), respectively. CVI and DVT were positively associated with injecting into the groin, while injecting into the leg was positively associated with leg ulcers and DVT. CVI was also associated with not cleaning injection sites and diagnosed hepatitis C virus, and DVT with hepatitis C virus., Discussion and Conclusion: The prevalence of vascular problems among PWID in London is very high in comparison to the general population. These conditions are primarily associated with injection into the femoral vein. Use of these injection sites indicates peripheral venous access problems. There is a need to reinvigorate safe injection information provision in harm reduction services, with attention to reducing risk practices associated with venous damage and transitions to femoral injection., (© 2021 Australasian Professional Society on Alcohol and other Drugs.)

Background: Coexistence of dilating venous diseases in different vascular territories has raised the idea that they have similar vascular wall abnormality in their evolutionary process. Accordingly, we aimed to evaluate venous leg symptoms in patients with hemorrhoidal disease (HD) by means of VEINES-Sym questionnaire., Materials and Methods: The study involved 249 consecutive patients who underwent colonoscopy and met the inclusion criteria. Presence and grading of HD were made according to Goligher's classification. All patients were examined for the existing of varicose vein and classified in respect of CEAP classification. All participants were requested to answer the VEINES-Sym questionnaire., Results: There was not statistically significant differences between the patients without HD (grade 0 or I) and with HD (Grade II or III) in respect to clinical characteristics except female predominance in hemorrhoid group (p = 0.07). Scores of heavy legs, swelling, burning sensation, restless leg, throbbing, tingling, and total VEINES score were significantly lower (ie: worse) in hemorrhoid group. Logistic regression analysis revealed that female gender and total VEINES score were independently associated with HD (OR: 2.03, 95% CI: 1.17-3.52, p  = 0.01; OR: 0.96, 95% CI: 0.92-0.99, p  = 0.02, respectively). Among all venous leg symptoms, severity of heavy legs, night cramps, swelling and aching were significantly correlated with the grades of HD., Conclusion: We have shown significant association between the HD and venous leg symptoms reflected by total VEINES score and significant correlation between the HD grade and venous leg symptoms severity including heavy legs, swelling, night cramps and aching legs.

Objective: To determine the frequency and stages of chronic venous disease (CVD) in health staff and its impact on the quality of life., Method: Cross-sectional study on health workers, between the ages of 20 and 60, indistinct gender, to remain standing position ≥6.5 hours per day for at least 5 days a week. Socio demographic variables were recorded. The Clinical-Etiology-Anatomy-Pathophysiology (CEAP) scale was used to stage the CVD; to measure the quality of life, the CIVIQ-20 (Chronic Venous Insufficiency Questionnaire) survey was applied at baseline, at 3 and 6 months. All patients underwent detailed clinical examination followed by color Doppler ultrasound and angiology review., Results: Included 37 patients, 62.1% woman. Average age was 36.6 ± 8.8 years. By CEAP the 78.3% of the patients presented CVD and the highest prevalence was C1; corroborating by Doppler ultrasound only in 29.7% of the patients. The predominant symptoms were night cramps (54.5%)., Conclusion: The frequency of CVD is like the literature. Patients with chronic venous disease have poor quality of life which improves with treatment., (Copyright: © 2022 Permanyer.)

Aim: This study aims to investigate self-care agency and quality of life (QoL) in persons with chronic venous disease of the lower extremities., Methods: This descriptive study was carried out between December 2014 and September 2016. The study population consisted of patients admitted to Erzurum Regional Training and Research Hospital Clinic of Surgical Cardiovascular Diseases and who had been diagnosed with lower extremity venous disease. The study sample comprised 312 patients who meet the inclusion criteria among this population admitted at the said dates. For data collection, the Patient Information Form, Self-Care Agency Scale, and Venous Insufficiency Epidemiological and Economic Study - Quality of Life/Symptoms Scale (VEINES-QOL/SYM) were used. The data were evaluated using percentage distribution, means, analysis of variance, post-hoc test, t-test, Mann-Whitney U-test and Kruskal-Wallis test., Results: The mean Self-Care Agency Scale score of the patients with lower extremity venous disease was 102.33±18.20, and their mean VEINES-QOL/Sym score was 74.95±12.86, indicating a moderate level., Conclusion: As a result, this study found the factors that significantly affected mean Self-Care Agency scores and mean QoL scores of the patients in terms of their level of education, employment status, BMI, smoking habits, and conditions about chronic diseases. Positive correlation was found between mean Self-Care Agency scores and QoL scores of the patients., Competing Interests: Declaration of Competing Interest Both authors declare that they have no competing interests.

Chronic venous insufficiency is the most common vascular disease. One of the major risk factors for its development is long-term sitting or standing in the same position and the nature of the work performed. This study aimed to evaluate the incidence of chronic venous insufficiency in a group of persons employed in workplaces with a predominance of standing or sitting positions, and to determine work-related and non-work risk factors. The research used two tools: questionnaires and medical examinations. The survey comprised 500 people, including 238 men (47.6%) and 262 women (52.4%), aged 25-60 years, 39.75 ± 10.80 years old on average. In addition, a group of 100 randomly selected people was subjected to medical examinations to confirm or exclude chronic venous insufficiency symptoms in the study group. The study showed a statistically significant correlation between postures adopted at work and the symptoms of chronic venous insufficiency of the lower limbs.

Chronic venous disease is a worldwide problem associated with significant morbidity and is expected to increase in prevalence as the current population ages. This is a comprehensive review of the anatomy, pathophysiology, genomics, clinical classification, and treatment modalities of chronic venous disease., (Copyright © 2021 Elsevier Inc.

Introduction: Data on the prevalence of chronic venous disorders (CVD) at the national level in Germany are scarce., Methods: We performed a population-based observational study based on clinical examinations, personal history, and technical examinations. Data were collected from 2006 to 2015. Descriptive data analysis was done to determine CVD and chronic venous insufficiency (CVI) prevalence and occurrence of potential risk factors. Chi-squared tests were performed to estimate the influence of risk factors on the prevalence of CVD., Results: In total, 19,104 employees from different branches were included. The majority of the examined people were doing office work (n = 8157; 80.2%). A total of 4038 persons (21.1%) show at least one sign of CVD. At least one sign of CVI could be found in 679 persons (3.6%). Being female was found to be protective with an odds ratio of 0.66 (95% CI 0.59-0.73)., Conclusion: There is clear indication for active venous treatment in 22.3% of the adult working population in Germany., Competing Interests: M Augustin has received a research grant and speaker honoraria from BSN medical GmbH. G Bruning has received travel grants from Bauerfeind AG. The authors report no other conflicts of interest in this work., (© 2021 Kirsten et al.)

Aims: Evidence regarding the health burden of chronic venous insufficiency (CVI), its clinical determinants, and impact on outcome is scarce., Methods and Results: Systematic phenotyping of CVI according to established CEAP (Clinical-Etiologic-Anatomic-Pathophysiologic) classification was performed in 12 423 participants (age range: 40-80 years) of the Gutenberg Health Study from April 2012 to April 2017. Prevalence was calculated age- and sex-specifically. Multivariable Poisson regression models were calculated to evaluate the relation of CVI with cardiovascular comorbidities. Survival analyses were carried out to assess the CVI-associated risk of death. Replication of findings was done in an independent cohort study (MyoVasc, NCT04064450). The prevalence of telangiectasia/reticular, varicose veins, and CVI was 36.5% [95% confidence interval (CI), 35.6-37.4%], 13.3% [12.6-13.9%], and 40.8% [39.9-41.7%], respectively. Age, female sex, arterial hypertension, obesity, smoking, and clinically overt cardiovascular disease were identified as clinical determinants of CVI. Higher CEAP classes were associated with a higher predicted 10-year risk for incident cardiovascular disease in individuals free of cardiovascular disease (n = 9923). During a mean follow-up of 6.4 ± 1.6 years, CVI was a strong predictor of all-cause death independent of the concomitant clinical profile and medication [hazard ratio (HR) 1.46 (95% CI 1.19-1.79), P = 0. 0003]. The association of CVI with an increased risk of all-cause death was externally validated in the MyoVasc cohort [HR 1.51 (95% CI 1.11-2.05), P = 0.009]., Conclusion: Chronic venous insufficiency is highly prevalent in the population and is associated with the presence of cardiovascular risk factors and disease. Individuals with CVI experience an elevated risk of death, which is independent of age and sex, and present cardiovascular risk factors and comorbidities., (Published on behalf of the European Society of Cardiology.

Introduction: Mixed arterial-venous lower extremity disease (AVLED) poses a unique challenge for clinicians. This review will outline the impact mixed AVLED has on patients and the healthcare system, by reviewing its epidemiology, diagnosis, current treatment, and the challenges encountered implementing therapies., Evidence Acquisition: An extensive search of current literature from online sources, journals and book chapters identified the current challenges facing the treatment of mixed arterial venous ulcers of the lower extremities and potential solutions to these challenges., Evidence Synthesis: The challenges that are identified in the search are the time to heal AVLED, patient education and motivation, early detection of AVLED, wound care center development, treatment consensus from multidisciplinary team members, and cost of treatment., Conclusions: AVLED ulcers are a challenging problem, but over time we have continued and will continue to improve patient care and tackle these difficult challenges as we have throughout the last century. A diagnostic algorithm to address how we approach these patients in terms of conservative care with wound care and compression and treat arterial and venous insufficiency is crucial. In looking to the future, continued standardization of wound care centers will overcome the social and financial challenges faced by patients and continued clinical research will improve targeted therapies and treatment challenges faced by physicians.

Background: Primary varicose veins (PVV) represent the most prominent clinical manifestation of chronic venous disease (CVD) and has a complex pathophysiological background. The aim of our study was to investigate the impact of sonographic hemodynamical and contemporary epidemiological factors on the clinical severity of PVV., Methods: We analyzed the sonographic hemodynamical and clinical parameters from 159 consecutive CVD patients and 233 lower limbs with PVV of clinical stages C2, C3 and C4. Univariate and logistic regression analysis was performed between patients of C2 (N.=70 - 30.0%) and C3 - 4 stages and between subgroups C3 (N.=101 - 43.3%) and C4 (N.=62 - 26.6%)., Results: Reflux of common femoral vein and saphenofemoral junction was detected in 43.3% and 65.7%. High venous reflux rates were found at the great saphenous above and below knee (90.1% - 53.2%) and in Cockett perforators (80.5%). Logistic regression revealed that factors associated with the symptomatic C3; 4 stages were the duration of disease >10 years (P=0.015, insufficiency in two or more perforators (P<0.001) and history of 2 pregnancies (P=0.001). Analysis C3 vs. C4 showed that insufficiency in two or more perforators increased the likelihood of advanced C4 clinical stage by 2.2 times, (P=0.037). An additional significant factor was the presence of at least one incompetent Cockett perforator., Conclusions: Clinical severity of PVV is correlated with a plethora of complex anatomical, hemodynamical and epidemiological factors. Insufficiency in two or more perforators seems to play the most important role and this highlights the value of preoperative venous ultrasound mapping.

Purpose: To evaluate the relationship between clinical severity and functionality, sleep quality, depression, and quality of life (QoL) in patients with CVI with or without leg ulcers., Methods: A total of sixty patients with CVI were enrolled in the study. The patients were C2-6 according to the CEAP classification. All the patients were assessed with Venous Clinical Severity Score (VCSS) for clinical severity, Visual Analog Scale (VAS) for pain, right and left lower limb (RLL and LLL) circumference measurements for edema, 6-min-walk test (6-MWT) for functional capacity, Lower Extremity Functional Scale (LEFS) for functionality, Pittsburg Sleep Quality Index (PSQI) for sleep quality, Beck Depression Inventory version I (BDI-I) for depression, and The Quality of Life Questionnaire for Chronic Venous Diseases-20 (CIVIQ-20) for QoL., Results: The mean age of the patients was 45.83 ± 13.25 years, and the mean duration of disease was 8.30 ± 7.42 years. There was a significant association between VCSS and VAS-rest/activity, edema-RLL/LLL, PSQI, BDI-I, LEFS, and CIVIQ-20 in patients without leg ulcers. In addition, a significant association was found between VCSS and VAS-rest/activity and CIVIQ-20 in patients with leg ulcers., Conclusion: The current study showed that an association has been found between clinical severity and pain at rest and during activity, edema, sleep quality, depression, lower extremity function, and QoL in patients without ulcers. However, clinical severity has been correlated with only pain at rest and during activity, and QoL in patients with leg ulcers., (Copyright © 2021 Tissue Viability Society. Published by Elsevier Ltd.

Venous disease is a term that broadly covers both venous thromboembolic disease and chronic venous disease. The basic pathophysiology of venous thromboembolism and chronic venous disease differ as venous thromboembolism results from an imbalance of hemostasis and thrombosis while chronic venous disease occurs in the setting of tissue damage because of prolonged venous hypertension. Both diseases are common and account for significant mortality and morbidity, respectively, and collectively make up a large health care burden. Despite both diseases having well-characterized environmental components, it has been known for decades that family history is an important risk factor, implicating a genetic element to a patient's risk. Our understanding of the pathogenesis of these diseases has greatly benefited from an expansion of population genetic studies from pioneering familial studies to large genome-wide association studies; we now have multiple risk loci for each venous disease. In this review, we will highlight the current state of knowledge on the epidemiology and genetics of venous thromboembolism and chronic venous disease and directions for future research.

The current limitations of surgical treatment, as well as restrictions on professional and sport activities related to COVID-19 pandemic require seeking therapeutic solutions for the vast population of patients with chronic venous insufficiency (CVI, chronic venous insufficiency). To understand the principles of pharmacotherapy of this disease, the authors used data related to epidemiology and pathophysiology of CVI. They provided the latest data on venoactive drugs and recommendations that should be followed and summarized the literature based on the EBM. The article should provide the answer to the question of how to deal with patients with varicose veins or, more broadly, chronic venous insufficiency during the pandemic.
