Background: Seventy percent of patients affected by SARS-COV-2 disease are asymptomatic or with symptoms that not required Hospitalization. A prodromal period lasting about 5 days can be identified. In this phase a patient with a positive swab for viral RNA may or may not evolve towards the phase of symptomatic disease., Methods: In this paper we reviewed the literature related to COVID-19 therapy we propose a reasoned treatment protocols in outpatients according to the age and the comorbidity., Results: The aim of this study was to reduce the impact of the virus by reducing its ability to attack cells and the inflammatory burden and the prothrombotic effects proposing two therapeutic schemes of proven efficacy according to the age of the patients and the comorbidities., Conclusions: We aimed to reduce worsening of clinical status and hospitalization while protecting patients at home.

Background: The study was initiated following the observation of complete recanalization of thrombus in subjects with DVT treated with rivaroxaban after 1-2 weeks. The aim of this observational retrospective study was to evaluate clinically and by means of echo color Duplex, the fibrinolytic effect of rivaroxaban in patients with recent and previous DVT. To accomplish this two populations of patients were evaluated., Methods: Group 1 was comprised of 31 patients (ranging in age 52-73 years) with popliteal-femoral DVT (12 months ago) treated with standard anticoagulant therapy. In these patients, we found a complete superficial femoral recanalization and partial recanalization of the popliteal vein (30% of residual thrombus). The patients had normal creatinine clearance and liver function. The patients were switched from warfarin to rivaroxaban due to a lack of compliance with warfarin therapy. Group 2 was comprised of 22 patients (ranging in age 65-82 years) with previous popliteal-femoral DVT and documented complete common femoral veins recanalization who presented with a recent superficial femoral vein re-thrombosis (1 week before). The patients had normal creatinine clearance and liver function. The patients switched from warfarin to rivaroxaban due to a lack of compliance with warfarin therapy., Results: In group 1, all patients exhibited the complete recanalization of the popliteal veins after 4 weeks of rivaroxaban therapy. In group 2, all patients exhibited the complete recanalization of the popliteal veins after 4 weeks, and the complete recanalization of the acute re-thrombosis of the superficial femoral veins after 2 weeks of rivaroxaban therapy. No adverse events for both groups were observed., Conclusions: Our results suggest that rivaroxaban could have a pro-fibrinolytic effect not only on recent thrombus but also on organized thrombus that results in a complete recanalization of affected veins. It is proposed that this lytic effect will preserve venous valve structure and lead to a reduction of incidence of post-thrombotic syndrome in rivaroxaban treated patients.

There are excellent guidelines for clinicians to manage venous diseases but few reviews to assess their hemodynamic background. Hemodynamic concepts that evolved in the past have largely remained unchallenged in recent decades, perhaps due to their often complicated nature and in part due to emergence of new diagnostic techniques. Duplex ultrasound scanning and other imaging techniques which evolved in the latter part of the 20th century have dominated investigation. They have greatly improved our understanding of the anatomical patterns of venous reflux and obstruction. However, they do not provide the physiological basis for understanding the hemodynamics of flow, pressure, compliance and resistance. Hemodynamic investigations appear to provide a better correlation with post-treatment clinical outcome and quality of life than ultrasound findings. There is a far better prospect for understanding the complete picture of the patient's disability and response to management by combining ultrasound with hemodynamic studies. Accordingly, at the instigation of Dr Angelo Scuderi, the Union Internationale de Phlebologie (UIP) executive board commissioned a large number of experts to assess all aspects of management for venous disease by evidence-based principles. These included experts from various member societies including the European Venous Forum (EVF), American Venous Forum (AVF), American College of Phlebology (ACP) and Cardiovascular Disease Educational and Research Trust (CDERT). Their aim was to confirm or dispel long-held hemodynamic principles and to provide a comprehensive review of venous hemodynamic concepts underlying the pathophysiology of lower limb venous disorders, their usefulness for investigating patients and the relevant hemodynamic changes associated with various forms of treatment. Chapter 1 is devoted to basic hemodynamic concepts and normal venous physiology. Chapter 2 presents the mechanism and magnitude of hemodynamic changes in acute deep vein thrombosis indicating their pathophysiological and clinical significance. Chapter 3 describes the hemodynamic changes that occur in different classes of chronic venous disease and their relation to the anatomic extent of disease in the macrocirculation and microcirculation. The next four chapters (Chapters 4-7) describe the hemodynamic changes resulting from treatmen by compression using different materials, intermittent compression devices, pharmacological agents and finally surgical or endovenous ablation. Chapter 8 discusses the unique hemodynamic features associated with alternative treatment techniques used by the CHIVA and ASVAL. Chapter 9 describes the hemodynamic effects following treatment to relieve pelvic reflux and obstruction. Finally, Chapter 10 demonstrates that contrary to general belief there is a moderate to good correlation between certain hemodynamic measurements and clinical severity of chronic venous disease. The authors believe that this document will be a timely asset to both clinicians and researchers alike. It is directed towards surgeons and physicians who are anxious to incorporate the conclusions of research into their daily practice. It is also directed to postgraduate trainees, vascular technologists and bioengineers, particularly to help them understand the hemodynamic background to pathophysiology, investigations and treatment of patients with venous disorders. Hopefully it will be a platform for those who would like to embark on new research in the field of venous disease.

Aim: High ligation (HL) and stripping of GSV can be distinguished in Babcock's radical ligation (RHL), and selective (SHL): the new technique consists to ligate the SFJ keeping some of the tributary veins. The study analyzes the neovascularization and recurrence incidence in the groin after the SHL., Methods: A retrospective study performed in a center specialized in venous surgery in Italy, it included 360 patients underwent unilateral varicose vein surgery from January 2001 to December 2008 (210 females and 150 males, mean aged 51.9 years, range 18 to 75 years, the limbs were 222 rights and 138 lefts), CEAP classification was C2,s. Operative technique was standardised to SFJ ligation with the SHL, the GSV was stripped to the level of the knee, multiple phlebectomies were performed and the ligation of the incontinent perforating veins was performed if it was necessary. All patients had a venous reflux from terminal valve of SFJ and the femoral valves were continent. All patients were submitted to clinical examination of the lower limbs and Duplex Scanning (DS) in the pre/postoperative period every year after surgery and by two independent operator in 2013. The follow-up is from 5 years for the patients operated in 2008 to 12 years for the patients operated in 2001., Results: The neovascularizations and recurrencies in the groin were founded in 7 patients, the incidence is 1.9% of the total cases. The GSV stump and the left tributaries were open to venous flow, it was no venous reflux from the groin, no venous thrombosis of the GSV stump were detected., Conclusion: The SHL of the SFJ is a reliable technique, decreasing the incidence of neovascularizations and recurrent varicose veins in the operated groin.

Aim: Several studies have demonstrated the effective antithrombotic action of mesoglycan to treat chronic venous disease (CVD). The study aimed to assess clinical and quality of life (QoL) (CIVIQ 20 questionnaire) improvements in mesoglycan-treated patients with clinical, etiological, anatomical and pathophysiological (CEAP) stages 2 and 3., Methods: The open, multicentre, uncontrolled, observational, prospective study involved treating patients with 50 mg x 2/day mesoglycan for 2 months and measuring improvement to lower-limb edema and QoL in the Global, Physical, Pain, Psychological, and Social Dimensions of the Chronic Venous Disease Quality-of-Life Questionnaire (CIVIQ 20) at the first, baseline visit (V1), at the end of treatment (V2) and 2 (V3) and 4 months after treatment completion (V4). At the last visit (V4), patient disease status was assessed objectively (by the treating physician) and subjectively (by the patient). The study population was divided into three groups: 1) patients with only varicose veins; 2) patients with only lower-limb edema; 3) patients with varicose veins and edema (ITT population)., Results: Seventy-five centers enrolled 1066 patients (ITT population); 914 patients completed the study. Mesoglycan treatment produced significant improvement of edema and lower-limb circumference at every visit, in both patients with edema alone and those with edema and varicose veins (paired sample t-test P<0.001). QoL improved significantly in all questionnaire dimensions in all three patient groups even after treatment was concluded (V2). Improvement continued up to the end of the study observation period (V4) (paired sample t-test P<0.001). Objective clinical improvement of the underlying CVD was found in 76.82% of patients with varicose veins alone, in 82.83% of patients with edema alone, and in 76.7% of patients with varicose veins and edema. Patients' own subjective assessment of improvement was 82.0%, 79.39% and 79.39% respectively for the three groups., Conclusion: Results showed mesoglycan treatment to improve QoL significantly in patients with CVD as measured by a specific questionnaire like the CIVIQ 20. The extent of average edema reduction observed at the last visit (4 months after the end of drug treatment), suggests mesoglycan might have an etiological role, modifying the physiological factors underlying CVD and not just affording temporary improvement of symptoms.

Aim: The rates of pregnant women with functional symptoms of venous insufficiency who accepted or refused to wear therapeutic compression stockings were evaluated and compared in relation to their clinical evolution and their compliance levels., Methods: The observational study was conducted in pregnant women between 4 and 28 weeks of amenorrhea presenting a CEAP C0S to C3S venous disease. Therapeutic compression stockings (BSN medical, UltraSheer Maternity stockings, 15-20 mmHg) were offered to pregnant women satisfying the inclusion criteria during routine check visits, and both groups of patients (those who accepted as well as those who refused) were followed up until the end of the pregnancy. The clinical profiles of both groups and the evolution of the venous insufficiency were monitored and compared. The women were requested to indicate pain and further quality of life parameter by means of a specific questionnaire (CIVIQ)., Results: Ninety-eight women were included in the study and followed up; 30.6% (N.=30) of the women refused to wear compression stockings (Wr), 69.4% accepted 10.6% were not compliant to a daily wear (Wanc) and 58.8% wore them every day (Wac). Leg pain was more prominent in case of the Wac group (49.5 ± 21.3) than in case of the Wanc (42.1 ± 20.4) and Wr groups (36.6 ± 18). Their global quality also decreased (48.8 ± 15.7 vs. 43.6 ± 16.1 and 36.6 ± 15.6). Regular use of compression stockings led to decrease of pain (Wac -17 ± 10.1 vs. Wanc -10.3 ± 10.5 vs. Wr -4.2 ± 9.8 [P < 0.0001]) and enhanced total quality of life (Wac 13.5 ± 9.6 vs. Wanc 10.7 ± 11.3 vs. Wr -3.3 ± 9.4 [P < 0.0001). Similar results were observed on the CIVIQ subscale (pain, psychological, social, physical impact of legs' pain on women quality of life)., Conclusion: In daily practice, more than two third of the pregnant women accepted to wear compression stockings. The use of compression stockings reduced the legs pain and increased the quality of life of pregnant women.

Aim: A method to classificate lymphedema has been needed to gather all the important information on the clinical evolution of the disease using a common language and an easy clinical applicability., Methods: The proposal for a new classification of the limb lymphedema was inspired by the C.E.A.P. classification for chronic venous insufficiency of the lower limb. The classification adopts the acronym C.E.A.P. by adding the letter L to underline the aspect ''lymphedema'' and is based on clinical data such as extension of lymphedema, presence of lymphangitis, leg ulcers and loss of functionality of the limb and instrumental criteria that permit to confirm and precise diagnosis. The Clinical classification is based on the most objective sign in these patients, the edema which is subdivided into 5 classes depending on the clinical manifestations. The etiological aspect considers 2 types of alterations of the lymphatic system: congenital and acquired. The anatomic is aimed to locate the anatomical structures involved. Pathophysiological conditions are gathered into 5 groups: agenesia or hypoplasia, hyperplasia, reflux, overload, obstruction., Results: The classification has already been appraised after 4 years of activity at the unit of Vascular and Endovascular Surgery of Ferrara, at the S. Giovanni Battista Hospital in Rome, at the Umberto I Ancona Hospital and at the S. Giovanni-Addolorata Hospital in Rome., Conclusions: The proposal for a new classification of lymphedema C.E.A.P. L was developed in order to categorize patients with definite and objective marks, creating clinical reports with a common vocabulary, clear to all clinicians, permitting to stage the disease, evaluate treatment and finally obtain epidemiological and statistical data.

The effectiveness of anticoagulant therapy for venous thromboembolism, with regards to both acute phase and long term prophylaxis, in patients with recurrent deep venous thrombosis (DVT) and persistence of risk factors, has been confirmed by many studies. However, it is not free of complications such as hemorrhage or, more rarely, skin necrosis. The patient, observed by us since 1994, was treated with oral vitamin K antagonists: he was affected by post-thrombotic syndrome and deficiency of congenital procoagulant factors (factor II heterozygote and MTHFR positive heterozygote) and secondary deficiency of procoagulant factors due to the consumption of protein C, with appearance of skin necrosis that occurred after many years of oral anticoagulant treatment. The change of therapy from oral anticoagulant to low molecular weight heparin and the use of local dressing, led to the resolution of the clinical symptoms and on to healing.
