Before the 20th century, peripheral artery disease (PAD) manifested as extreme pain, chronic wounds, and, eventually, gangrene requiring amputation. Despite this, it was rarely diagnosed. However, at the turn of the century, Western medicine shifted focus from infectious to chronic illnesses, and with this change, physicians' engagement with PAD transformed. Aiming to mitigate long-term injury, physicians now worked to identify and treat vessel disease to restore meaningful blood circulation. This article explores the development and deployment of a new device resulting from this refocus, the PAssive VAscular EXerciser (PAVAEX) Boot, and its role as a creative response to a previously intractable clinical problem. The PAVAEX Boot, designed in 1933 by vascular surgeons Louis G. Herrmann and Mont R. Reid, was one of the few interventions for PAD at the time. Based on the observation that continuous negative pressure results in vasoconstriction, while short bursts transiently increase blood flow, the PAVAEX Boot utilized intermittent negative pressure to enhance peripheral vascular perfusion. Well-marketed and praised throughout the 1930s, it vanished from public writing and academic literature just 20 years later. However, negative pressure wound therapy resurged in the late 20th century, and though its inventors failed to recognize the precedent of the PAVAEX Boot, many of these devices and therapies are rooted in identical theories. We examine why the PAVAEX Boot faded from use and argue that the device remains a crucial advancement in negative pressure therapy. [ABSTRACT FROM AUTHOR]

Background: Cardiopulmonary exercise testing (CPET) is a preoperative risk stratification tool providing an objective measure of fitness and functional capacity. There is however little evidence on the use of this compared to non-physiological test in vascular surgery despite its current use. This study investigates whether CPET perioperatively has value alongside non-physiological testing for patients undergoing elective open abdominal aortic aneurysm (AAA) repair. Method: Retrospective data was collected at 2 vascular centres between 2015-2019 in a CPET centre vs non-CPET centre in patients undergoing elective AAA repair. Outcomes measured included: length of stay in an intensive care unit (ICU); total length of stay; post-operative complications and acute kidney injury (AKI). Statistical analysis was performed using IBM SPSS software. Results: There were 38 patients at each centre. The mean duration of stay in ICU for patients in CPET centre was 2.5 ± 2.13 days whilst in non-CPET centre it was 3.68 ± 4.08 days (P = 0.05). The mean duration of stay in ICU and total length of stay was significantly shorter in CPET centre (P = 0.05 and P = 0.015 respectively). Mortality in CPET centre was 2.63% and 5.26% in non-CPET centre (not significant). The number of patients developing AKI post-operatively was 13.61% in CPET vs 28.95% in non-CPET centre. Conclusion: CPET tested patients have statistically significant lower length of total and ICU stay compared to non-CPET patients. CPET is therefore a useful adjunct in selecting patients for open surgery compared to non-physiological testing. This study provides some evidence on the use of this routinely but not validated assessment tool in aortic aneurysm repair. [ABSTRACT FROM AUTHOR]

Retropharyngeal internal carotid artery (ICA) is a rare, yet well-described anatomical variant that poses significant challenges to the management of carotid artery stenosis. In this case report, we discuss the treatment of symptomatic ICA stenosis with a retropharyngeal ICA using the transcarotid artery revascularization (TCAR) technique. A 70-year-old female with comorbidities presented with neurological symptoms and severe ICA stenosis. After diagnostic evaluation, TCAR was chosen for surgical intervention. The patient did well postoperatively. This case emphasizes the importance of considering TCAR when treating ICA stenosis in patients with anatomic variation of ICA location. It also supports adding anatomic variants such as retropharyngeal ICA to the list of indications for TCAR. [ABSTRACT FROM AUTHOR]

Acute limb ischemia (ALI) is the sudden onset of decreased blood supply to the extremities and carries a poor prognosis for the affected limb and survival. A rare but well-recognized embolic etiology is a paradoxical embolism, the translocation of a thrombus from venous to arterial circulation through an intracardiac communication, most commonly a patent foramen ovale. The presentation of ALI secondary to a PFO-mediated paradoxical embolism is most often accompanied by combinations of deep vein thrombosis (DVT), pulmonary embolism (PE), and an acute cerebral or visceral ischemia. We present the first documented case of a Rutherford class I ALI secondary to a PFO-mediated paradoxical embolism, ipsilateral DVT, and PE in a 29-year-old female who was surgically managed for her disabling claudication rather than limb salvage. The overlapping presentation of a viable ALI and ipsilateral DVT created a challenging clinical diagnosis. Our review of the literature on PFO-mediated paradoxical emboli involved 43 reports including 51 patients with various arterial thromboses; 19 of these cases involved lower extremity ALI. This case report is the first case to date that demonstrates a paradoxical embolism causing acute lower extremity ischemia with ipsilateral DVT and no additional limb/visceral ischemia to suggest the diagnosis of ALI. We also highlight the role that quality of life plays in vascular surgical decision-making, extending ALI management goals to not only reducing mortality and major amputations, but also improving quality of life.

Background: Postoperative carotid endarterectomy (CEA) patch infection is a rare but well‐recognized complication of CEA. It is important for otolaryngologists to be aware of the presentation and challenges in its diagnosis. Methods: Patients who presented with a neck mass or hemorrhage and a known prior history of carotid endarterectomy with synthetic patch reconstruction were worked up with ultrasound, CT, or MRI imaging. In one case, fine needle aspiration biopsy was performed. Ultimately, all patients were taken to the operating room for neck exploration. Results: Of the three patients presented in this case series, two presented with a chronic neck mass, two‐to‐three years after carotid endarterectomy. One patient presented acutely with hemorrhage from the carotid endarterectomy site. Carotid patch infection was diagnosed after neck exploration in all cases. Vascular surgery was consulted intra‐operatively to perform definitive vascular repair. Conclusions: Infected carotid patch should be suspected in patients with a history of prior CEA, as many of the presenting complaints may resemble or mimic pathology managed by otolaryngology. The onset of symptoms can be perioperative or very delayed. A multidisciplinary approach with vascular surgery and infectious disease is required for appropriate management of these patients.

Background The sartorius is a muscle of lower limb thigh with variant morphological distribution of blood supply. The detailed knowledge vascular patterns of the muscle and overlying skin is an absolute guide in reconstructive surgery. In this study the vascular pattern is analyzed by dissection method both in sartorius and overlying skin. Methods 50 sartorius muscles and the circumferential skin of the thigh were dissected from 25 cadavers. Anatomical morphology and Morphometrical parameters, such as pedicle number, location, diameter, and length, are recorded using vernier callipers. Thread method was used to measure the length of muscle supplied by a single pedicle which is defined as a major pedicle. Lastly, the area of cutaneous territory of each major pedicle was calculated. Results The sartorius muscle is supplied by 5 to 8 vascular pedicles. The major pedicles are proximal 20 to 28 cms from ASIS size around 2cms Distal major pedicle 32 to 40 cms from ASIS size around 2mm. Conclusion This vascular anatomical pattern study is a guideline in freeflap surgeries of sartorius muscle during transposition with the pedical of the sartorius muscle. [ABSTRACT FROM AUTHOR]

Background: There is wide variation in stress test utilization before major vascular surgery and adherence to practice guidelines is unclear. We defined rates of stress test compliance at our institution and led a quality improvement initiative to improve compliance with American Heart Association (ACC/AHA) guidelines. Methods: We implemented a stress testing order set in the electronic medical record at one tertiary hospital. We reviewed all patients who underwent elective, major vascular surgery in the 6 months before (Jan 1, 2022 – Jul 1, 2022) and 6 months after (Aug 1, 2022 – Jan 31, 2023) implementation. We studied stress test guideline compliance, changes in medical or surgical management, and major adverse cardiac events (MACE). Results: Before order set implementation, 37/122 patients (30%) underwent stress testing within the past year (29 specifically ordered preoperatively) with 66% (19/29) guideline compliance. After order set implementation, 50/173 patients (29%) underwent stress testing within the past year (41 specifically ordered preoperatively) with 80% (33/41) guideline compliance. In the pre- and postimplementation cohorts, stress testing led to a cardiovascular medication change or preoperative coronary revascularization in 24% (7/29) and 27% (11/41) of patients, and a staged surgery or less invasive anesthetic strategy in 14% (4/29) and 4.9% (2/41) of patients, respectively. All unindicated stress tests were surgeon-ordered and none led to a change in management. There was no change in MACE after order set implementation. Conclusions: Electronic medical record-based guidance of perioperative stress testing led to a slight decrease in overall stress testing and an increase in guideline-compliant testing. Our study highlights a need for improved preoperative cardiovascular risk assessment prior to major vascular surgery, which may eliminate unnecessary testing and more effectively guide perioperative decision-making.

Background: Endoscopic resection has been reported for vascular anomalies (VA) previously. However, there is no study comparing endoscopic resection surgery (ERS) with open resection surgery (ORS) in children. We aimed to compare clinical and cosmetic outcomes between two approaches in pediatric VA. Methods: Between June 2018 and June 2023, 138 pediatric VA patients undergoing ERS or ORS were retrospectively reviewed. Propensity score matching (PSM) was performed to minimize selection bias. The Scar Cosmesis Assessment and Rating (SCAR) Scale and numerical rating scale (NRS) based on patient satisfaction were used for cosmetic assessment. Results: After PSM for age, depth of lesion, size of lesion, and site of surgery, 72 patients (ERS = 24, ORS = 48) were analyzed. Patients undergoing ERS had longer operative time (164.25 ± 18.46 vs. 112.85 ± 14.26 min; P < 0.001), less estimated blood loss (5.42 ± 2.15 vs. 18.04 ± 1.62 ml; P < 0.001), and shorter median hospital stay (4.50 [3.00–5.00] vs. 6.00 [5.00–6.00] days; P < 0.001). The follow-up time was 8.04 ± 1.23 month for ERS group and 8.56 ± 1.57 month for ORS group. For aesthetic results, the median overall SCAR score in ERS was lower than that in ORS (2 [1–3] vs. 5 [4–5]; P < 0.001), and the subscales of "scar spread," "dyspigmentation," "track marks or suture marks," and "overall impression" were better. The median NRS score was higher (8 [7–8] vs. 6 [5–6]; P < 0.001) and length of scars was shorter (2.18 ± 0.30 vs. 8.75 ± 1.98 cm; P < 0.001) in ERS group than those in ORS group. The incidences of total complications and recurrence showed no significant difference between two groups. Conclusions: Endoscopic surgery can be a safe and effective option for pediatric VA in the limbs and trunk. It offers the advantages of improving aesthetic outcomes and reducing postoperative wound healing time. [ABSTRACT FROM AUTHOR]

Objectives: Smoking is an important modifiable risk factor in all vascular diseases and verbal advice from providers has been shown to increase rates of tobacco cessation. We sought to identify factors that will improve tobacco cessation and recall of receiving verbal cessation advice in vascular surgery patients at a single institution. Methods: The study is a retrospective cohort study. Patients seen in outpatient vascular surgery clinic who triggered a tobacco Best Practice Advisory (BPA) during their office visits over a 10-month period were contacted post-clinic and administered surveys detailing smoking status, cessation advice recall, and validated scales for nicotine dependence and willingness to quit smoking. This BPA is a "hard stop" that requires providers to document actions taken. Charts were reviewed for tobacco cessation documentation. Nine-digit zip-codes identified the area deprivation index, a measure of socioeconomic status. Univariate analysis was used to identify factors associated with cessation and advice recall. Results: One hundred out of 318 (31.4%) patients responded to the survey. Epic Slicer Dicer found 97 BPA responses. To dismiss the BPA, 89 providers (91.8%) selected "advised tobacco cessation" and "Unable to Advise" otherwise. Of the 318 patients, 115 (36.1%) had cessation intervention documented in their provider notes and 151 (47.5%) received written tobacco cessation advice. Of survey respondents, 70 recalled receiving verbal advice, 27 recalled receiving written advice, 28 reported receiving offers of medication/therapy for cessation. 55 patients reported having tobacco cessation plans, and among those 17 reported having quit tobacco. Recall of receiving written advice (P <.001) and recall of receiving medication/therapy (P =.008) were associated with recall of receiving verbal cessation advice. Conclusions: Providing patients with tobacco cessation medication/therapy and written tobacco cessation education during office visits is associated with increased patients' recall of tobacco cessation advice. Vascular surgeons should continue to provide directed tobacco cessation advice. [ABSTRACT FROM AUTHOR]

Few studies describe outcomes after complete vascular ring surgery in a comprehensive manner. This study sought to describe the clinical presentation, diagnostic work-up, operative approach, and outcomes in children undergoing surgery for complete vascular rings. This single-center retrospective cohort study includes consecutive patients (January 1990 through September 2023) undergoing primary surgery for complete vascular rings, or rerepair after primary surgery elsewhere. The primary outcome of interest was complete (as distinct from partial) symptom resolution at latest clinic follow-up. Our current preference is to pursue a comprehensive initial operation including adjunctive vascular and airway procedures targeting common causes of residual aerodigestive symptoms, such as Kommerell diverticulum resection and tracheobronchopexy. Preoperative work-up routinely involved computed tomographic angiography, dynamic bronchoscopy, and laryngoscopy. Of 515 patients (including 39 rerepairs), the most common diagnoses were right aortic arch with aberrant left subclavian artery and left ligamentum arteriosum (n = 323, 62.7%) and double aortic arch (n = 174, 33.8%). There was no perioperative mortality. Chylothorax occurred in 28 patients (5.4%), vocal cord dysfunction in 22 patients (4.3%), and diaphragm paralysis in 2 patients (0.4%). Follow-up was available on 453 patients (88.0%) with a median duration of 3.0 years (Q1-Q3: 0.6-9.2 years). At latest clinic follow-up, 429 patients (94.7%) reported complete symptom resolution. The risk of reoperation for residual or recurrent aerodigestive symptoms was 9.6% (95% CI: 5.7%-13.5%) at 10 years and 12.4% at 20 years (95% CI: 6.9%-17.8%). Surgery for complete vascular rings provides good symptomatic relief with low risk of complications, whereas reoperations for aerodigestive symptoms are infrequent. [ABSTRACT FROM AUTHOR]

Background: Disruption score (DS) is a novel bibliometric created to identify research that shifts paradigms, which may be overlooked by citation count (CC). We analyzed the most disruptive, compared to the most cited, literature in vascular surgery, and hypothesized that DS and CC would not correlate. Methods: A PubMed search identified vascular surgery publications from 1954 to 2014. The publications were linked to the iCite NIH tool and DS algorithm to identify the top 100 studies by CC and DS, respectively. The publications were reviewed for study focus, design, and contribution, and subsequently compared. Results: A total of 56,640 publications were identified. The top 100 DS papers were frequently published in J Vasc Sur (43%) and Eur J Vasc Endovasc Surg (13%). The top 100 CC paperswere frequently published in N Engl J Med (32%) and J Vasc Sur (20%). The most cited article is the fifth most disruptive; the most disruptive article is not in the top 100 cited papers. The DS papers had a higher mean DS than the CC papers (.17 vs .0001, P < .0001). The CC papers had a higher mean CC than the DS papers (866 vs 188, P < .0001). DS and CC are weakly correlated metrics (r = .22, P = .03). Discussion: DS was weakly correlated with CC and captured a unique subset of literature that created paradigm shifts in vascular surgery. DS should be utilized as an adjunct to CC to avoid overlooking impactful research and influential researchers, and to measure true academic productivity. [ABSTRACT FROM AUTHOR]

Objective: Chronic ischemia-related cavernous dysfunction is considered irreversible. However, in certain patients, cavernous function appears to recover with penile revascularization. In this study, we investigated a potential cavernous dysfunction reversibility from a clinical perspective. Patients and Methods: We involved 93 young patients in the study with arterial erectile dysfunction (ED) (median age: 30 years). Erectile function tests were performed according to the standard operating procedures of the International Society of Sexual Medicine. Among the participants, 63 and 30 displayed pure arteriogenic and mixed vasculogenic (due to both arterial insufficiency and cavernous dysfunction) ED, respectively. Penile revascularization was performed by anastomosing the inferior epigastric artery to the dorsal artery. The ED treatment success was considered from a score of at least 24 on the International Index of Erectile Function-6. Results: Our results proved that penile revascularization cured 92.1% and 73.8% of the patients with pure arteriogenic and mixed vasculogenic ED, respectively (Kaplan-Meier method, log-rank test: no significant difference). The required time for curing 50% of the patients was 10.5 and 10.0 months for pure arteriogenic and mixed vasculogenic ED, respectively, indicating no recovery delay in patients with mixed vascular ED. Furthermore, the cavernous dysfunction degree did not influence cavernous function recovery. Conclusion: Penile revascularization cured ED in 73.8% of the patients with mixed vasculogenic ED. Cavernous dysfunction appears to be reversible in certain cases. Furthermore, we observed no delay in functional recovery compared to participants with healthy cavernous function. These two discoveries suggest that cavernous function recovery after penile revascularization is similar to the concept of hibernating myocardium in ischemic myocardium. Although cavernous dysfunction is considered irreversible, it could be reversed in multiple cases with blood flow restoration to the cavernous tissue. [ABSTRACT FROM AUTHOR]

Background: Peripheral vascular interventions (PVIs) performed under procedural sedation and analgesia (PSA) can be associated with anxiety and poor compliance with patient instructions during surgery. Mind-body interventions (MBIs) such as meditation have demonstrated the potential to decrease perioperative anxiety, though this area is understudied, and no tailored interventions have been developed for the vascular surgical patient population. Objectives: We aimed to design a perioperative MBI that specifically targeted vascular surgical patients undergoing PVIs under PSA. We sought to perform this in a scientifically rigorous, multi-disciplinary collaborative manner. Methods: Following the Obesity-Related Behavioral Intervention Trials (ORBIT) model, we designed (Phase 1a) and then refined (Phase 1b) a MBI for patients undergoing PVIs under PSA to decrease perioperative anxiety and sedation and facilitate patient intraoperative compliance. Phase 1a involved a literature review, informal information gathering and synthesis, and drafting a preliminary protocol for a perioperative MBI. Phase 1b involved assembling a multi-disciplinary expert panel of perioperative and mind-body clinicians and researchers to improve the MBI using an iterative, modified Delphi approach. Results: The modified Delphi process was completed, and a consensus was reached after three iterations. The resulting MBI consisted of two seven-minute preoperative guided meditations on the day of surgery, including diaphragmatic breathing, body scans, and guided imagery emphasizing awareness of the ipsilateral leg where the vascular surgery was performed. A document delineating the integration of the MBI into the operating room workflow was produced, including details regarding the intervention's timing, duration, and modality. Conclusion: Using a multi-specialty expert panel, we designed a novel MBI in the form of a guided meditation with elements of mindfulness and guided imagery to decrease anxiety and increase intraoperative compliance for patients undergoing PVIs under PSA. A prospective pilot study is being planned to test the program's feasibility. [ABSTRACT FROM AUTHOR]

Purpose: Anatomical understanding is an important basis for medical teaching, especially in a surgical context. The interpretation of complex vascular structures via two-dimensional visualization can yet be difficult, particularly for students. The objective of this study was to investigate the feasibility of an MxR-assisted educational approach in vascular surgery undergraduate education, comparing an MxR-based teaching-intervention with CT-based material for learning and understanding the vascular morphology of the thoracic aorta. Methods: In a prospective randomized controlled trial learning success and diagnostic skills following an MxR- vs. a CT-based intervention was investigated in 120 thoracic aortic visualizations. Secondary outcomes were motivation, system-usability as well as workload/satisfaction. Motivational factors and training-experience were also assessed. Twelve students (7 females; mean age: 23 years) were randomized into two groups undergoing educational intervention with MxR or CT. Results: Evaluation of learning success showed a mean improvement of 1.17 points (max.score: 10; 95%CI: 0.36–1.97). The MxR-group has improved by a mean of 1.33 [95% CI: 0.16–2.51], against 1.0 points [95% CI: -0.71- 2.71] in the CT-group. Regarding diagnostic skills, both groups performed equally (CT-group: 58.25 ± 7.86 vs. MxR-group:58.5 ± 6.60; max. score 92.0). 11/12 participants were convinced that MxR facilitated learning of vascular morphologies. The usability of the MxR-system was rated positively, and the perceived workload was low. Conclusion: MxR-systems can be a valuable addition to vascular surgery education. Further evaluation of the technology in larger teaching situations are required. Especially regarding the acquisition of practical skills, the use of MxR-systems offers interesting application possibilities in surgical education. [ABSTRACT FROM AUTHOR]

Chronic limb-threatening ischemia (CLTI) represents the advanced stages of peripheral arterial disease (PAD) and is caused by atherosclerotic damage in the lower limbs, having a greater risk of major amputation. The aim of this study was to analyze the impact of systemic immune index (SII), systemic inflammation response index (SIRI), and the aggregate index of systemic inflammation (AISI) on the clinical severity and long-term risk of amputation among patients with CLTI after percutaneous transluminal angioplasty (PTA). This is a retrospective observational study involving 104 patients diagnosed with CLTI and treated with PTA. Based on clinical severity, the cohort was divided into two groups: stage III Leriche-Fontaine and stage IV Leriche-Fontaine. We observed higher levels of SII (p = 0.027), SIRI (p = 0.0008), and AISI (p = 0.0024) in patients with trophic lesions. Kaplan–Meier analysis showed that patients with values of SII (p = 0.008), SIRI (p = 0.022), and AISI (p = 0.006) above the median at the time of admission are at a higher risk of major amputation in the long term following PTA. At the multivariate regression analysis, high baseline values of SIRI (odds ratio (OR) = 2.28; p = 0.017) and AISI (OR = 2.32; p = 0.043) were associated with stage IV Leriche-Fontaine, but not SII (OR = 1.71; p = 0.055). Additionally, in the Cox regression analysis, we found that SII (hazard ratio (HR) = 1.56; p = 0.010), SIRI (HR = 1.63; p = 0.009), and AISI (HR = 1.55; p = 0.016) are predictive factors for long-term risk of major amputation after endovascular treatment. Elevated levels of SIRI and AISI have been found to be linked with the severity of clinical symptoms and an increased risk of long-term major amputation in patients with CLTI following PTA. Additionally, higher baseline values for SII were associated with a greater risk of major amputation, but not with clinical severity in the same group of patients. [ABSTRACT FROM AUTHOR]

Surgeries for chronic pancreatitis are tailored based on disease process and either include parenchymal-preserving surgeries or total pancreatectomy with or without islet cell autotransplantation. It is critical to account for vascular variants as injuries to these are associated with short- and long-term morbidity and mortality. There is a lack of contemporary data on the true incidence of aberrant arterial anatomy, and it is likely to be underreported by nonhepatobiliary radiologists. This study is a retrospective analysis of all patients undergoing pancreatic resections for chronic pancreatitis at the single center. The presence of vascular variants was compared between standard reporting and preoperative imaging review by a hepatobiliary radiologist and surgeon. Primary outcomes were operative time and blood loss. Of the 72 pancreatic resections for chronic pancreatitis, 50 (69%) satisfied inclusion criteria. Three of fifty (6%) had vascular anomalies reported on standard reporting while 11 (22%) had vascular anomalies identified on preoperative imaging review and confirmed at surgery. Hence, only 27% of patients with variant vascular anatomy were reported on standard imaging. There was no significant difference in operative times or blood loss between those with and without known vascular anomalies. Pancreatic resection is a complex undertaking as long-standing inflammation distorts anatomic planes and increases opportunity for inadvertent vascular injury especially if there are aberrant vessels. In this study, we found that anatomic vascular variants are oftentimes not reported. Dedicated surgical planning with review of cross-sectional imaging identified all cases of anatomic variants resulting in no difference in operative time or incidence of intraoperative hemorrhage.

Residency interviews have traditionally been conducted in person; however, COVID-19 forced programs to shift to virtual interviewing. This study delineated the nationwide trends observed after virtual interviewing across multiple application cycles on both surgical residency applicant competitiveness and program workload. Publicly available National Residency Matching Program applicant and program data were retrospectively reviewed. Applicant competitiveness was assessed using a validated competitive index (# positions ranked/match rate). Interview types included in-person (2010-2020) or virtual (2021-2023), and programs were classified as general surgery (GS), surgical subspecialty (SS) – orthopedics, otolaryngology and neurosurgery, and integrated specialty (IS) – plastic, thoracic, and vascular surgery. When comparing in-person to virtual cohorts, the competitive index has increased in GS (0.97 ± 0.00 to 1.05 ± 0.01, P < 0.001), SS (0.97 ± 0.02 to 1.06 ± 0.01 P < 0.001), and IS (0.93 ± 0.06 to 1.12 ± 0.03, P = 0.001). United Sates Medical Licensing Examination Step scores and research experiences increased over time in GS and SS (P < 0.05). Program workload, represented by number of applications received per program increased in GS, IS, and SS (P < 0.05), as well as the number of interviews conducted in GS and SS (P < 0.05). Importantly, match rate remained stable in GS and IS, with a decrease in SS (0.69 ± 0.03 to 0.63 ± 0.02, P = 0.04). The residency application process has been irrevocably changed due to COVID-19. The rise in applicant volume and competitiveness places unique strains on applicants and programs. Additional modifications such as signaling and ACGME guidance are needed to help alleviate strain and ensure that residents and programs alike find their best fit. [ABSTRACT FROM AUTHOR]

Female patients frequently experience worse clinical outcomes than male patients after undergoing vascular surgery procedures. However, it is unclear whether these sex-based disparities also impact mental health outcomes. This study was designed to investigate sex differences in patient-reported outcome measures of depression for patients undergoing vascular surgery. We retrospectively analyzed 107 patients (73 males and 34 females) who underwent vascular surgery procedures between January 2016 and April 2023. These patients completed a Patient-Reported Outcome Measurement Information System (PROMIS) Item Bank v1.0-Depression assessment 90 d before surgery and at least once after surgery. After stratifying patients by sex, we analyzed changes in PROMIS depression scores using a multiple mixed-effects linear regression model. Then, logistic regression was used to compare the proportion of patients who achieved a clinically meaningful difference in PROMIS depression score within 15 mo after surgery. There was no significant difference between female and male patients among rates of complications, length of hospital stay, or rates of nonhome discharge. However, female sex was associated with significantly improved PROMIS depression scores after surgery compared to male sex (P = 0.034). Furthermore, female patients were over 3-fold more likely than male patients to reach the minimal clinically important difference threshold for improvement in PROMIS depression scores (odds ratio 4.66, 95% confidence interval 1.39-15.61). These results suggest that female sex is associated with improved patient-reported measures of depression after undergoing vascular surgery. Clinicians should consider these mental health benefits when evaluating female patients for vascular interventions. • Females more likely to achieve minimal clinically important difference in Patient-Reported Outcome Measurement Information System depression after vascular surgery. • No sex differences found in clinical outcomes after vascular surgery. • Mental health outcomes are important to evaluate following surgical procedures.

Introduction: Delays exist at each stage of the chronic limb‐threatening ischaemia (CLTI) care pathway, but there is little known about patient factors influencing delay to diagnosis of CLTI. This study explores the experiences and perceptions of patients recently diagnosed with CLTI. Methods: A qualitative interview study was conducted. Sixteen participants underwent semi‐structured interviews. Reflexive thematic analysis was performed on the data, aiming to understand factors which can influence delay in the CLTI care pathway. Results: Five interrelated themes were developed: CLTI is a devastating condition; Reluctance to ask for help; When we are empowered we get better care; Luck plays a role in the process to diagnosis; and Vascular units can do better, comprising sub‐themes of information transfer—consider communication and arterial versus non‐arterial centres—proximity isn't everything. Conclusions: The five themes generated from the interview data describe factors relevant to delay given meaning by participants who have lived experience of CLTI. Theme content should be noted by clinicians, commissioners and providers looking to improve care pathways for patients with CLTI. The importance of awareness for the public, patients and clinicians linked ideas in some themes and interventions to raise awareness should be considered. [ABSTRACT FROM AUTHOR]

Traumatic injury leading to arterial damage has traditionally been repaired using autologous vein graft from the contralateral limb. This often requires a secondary surgical site and the potential of prolonged operative time for patients. We sought to assess the use of ipsilateral vs contralateral vein grafts in patients who experienced traumatic extremity vascular injury. A multicenter database was queried to identify arterial injuries requiring operative intervention with vein grafting. The primary outcome of interest was need for operative reintervention. Secondary outcomes included risk of thrombosis, infection, and intensive care unit length of stay. 358 patients (320 contralateral and 38 ipsilateral) were included in the analysis. The ipsilateral vein cohort did not display a statistically significant decrease in need for reoperation when compared to the contralateral group (11% vs 23%; OR 0.41, 95% CI −0.07-1.3; P =.14). Contralateral repair was associated with longer median intensive care unit (ICU) LOS (4.3 vs 3.1 days; P <.01). [ABSTRACT FROM AUTHOR]

Introduction Deep vein thrombosis (DVT) poses a complex challenge and often leads to postthrombotic syndrome (PTS), a debilitating complication. The emergence of venous stents offers a potential preventive avenue against this complication. This study aimed to provide consensus recommendations on the use of venous stent for DVT. Materials and Methods From June to July 2023, 20 internal medicine, angiology and vascular surgery, and vascular and interventional radiology experts were involved in the Delphi process. Thirty-one recommendations, categorized into three thematic areas, were rigorously evaluated: indications for stent use, stent selection and placement, and monitoring and prevention of complications. Agreement was evaluated using a Likert scale, with consensus defined as agreement by two-thirds of the participants. Results Consensus was reached for 23 (74.2%) of 31 recommendations. The agreement was centered on considerations, such as stent placement in specific acute DVT scenarios, emphasizing pivotal stent characteristics. However, there were divergences in the recommended stent length to prevent migration and stent characteristics based on iliocaval bifurcation morphology. Notably, there was no consensus on whether patients with DVT caused by a major transient risk factor need more than 3 months of anticoagulation therapy or whether aspirin should be added to anticoagulant treatment after venous stenting. Conclusions These consensus recommendations offer practical insights into optimizing venous stent use to prevent PTS in DVT patients. Addressing the critical aspects of stent selection, placement, and postprocedural care, these recommendations contribute to clinical decision-making. The identified divergences underscore the importance of consensus and thus indicate the need for further investigation. [ABSTRACT FROM AUTHOR]

Laparoscopic liver resection (LLR) has been associated with improved patient recovery as well as reduced postoperative adhesions compared to open LR (OLR) and could therefore facilitate redo liver surgery. LLR prior to liver transplantation (LT) is increasingly performed, LT being saved for HCC recurrence. LT is still performed by open surgery due to vascular reconstructions and underlying liver chronic disease. We evaluated the impact of laparoscopic approach for LR prior to LT in terms of intraoperative transfusions, adhesions severity and outcome. Data from all patients who underwent a LT after LR in two French high-volume tertiary centers were retrospectively reviewed. The impact of LLR on per operative and postoperative outcome was assessed using logistic regression. 170 patients were included, 43 patients in the LLR group and 127 in the OLR group. Preoperative characteristics were comparable between both groups, except LLR group included more patients with "very early-stage" BCLC tumors than OLR group (51% vs. 33%, p = 0.02) and less anatomical resections (54% vs. 75%, p = 0.015). During LT, the transfusion rate was significantly higher in the OLR group (71.4% vs 44.2%, p = 0.002) as well as the proportion of type III adhesions according to OLSG classification (p < 0.001). Multivariate analysis found LLR to be an independent protective factor for adhesions and transfusion (p = 0.001 and p = 0.03 respectively). Laparoscopic liver resection was associated with reduced postoperative adhesions and transfusion requirements during subsequent liver transplantation. [ABSTRACT FROM AUTHOR]

As the population ages, vascular surgeons are treating progressively older, multimorbid patients at risk of peri-operative complications. An embedded physician has been shown to improve outcomes in general and orthopaedic surgery. This systematic review and meta-analysis aimed to investigate the impact of surgeon–physician co-management models on morbidity and mortality rates in vascular inpatients. PubMed, Scopus, Embase, conference abstract listings, and clinical trial registries. Studies comparing adult vascular surgery inpatients under co-management with standard of care were eligible. The relative risks (RRs) of death, medical complications, and 30 day re-admission between co-management and standard care were calculated. The effect of co-management on the mean length of stay was calculated using weighted means. Risk of bias was assessed using the Methodological Index for Non-Randomised Studies, and certainty assessment with the GRADE analysis tools. No randomised controlled trials were identified. Eight single institution studies between 2011 and 2020 with 7 410 patients were included. All studies were observational using before–after methodology. Studies were of high to moderate risk of bias, and outcomes were of very low GRADE certainty of evidence. Co-management was associated with a statistically significant lower relative risk of death (RR 0.64, 95% confidence interval [CI] 0.44 – 0.92; p =.02), cardiac complications (RR 0.47, 95% CI 0.25 – 0.87; p =.02), and infective complications (RR 0.49, 95% CI 0.35 – 0.67; p <.001) in vascular inpatients. No statistically significant differences in length of stay (standard mean difference –0.6 days, 95% CI –1.44 – 0.24 days; p =.16) and 30 day re-admission (RR 0.96, 95% CI 0.84 – 1.08; p =.49) were noted. Early results of physician and surgeon co-management for vascular surgery inpatients showed promising results from very low certainty data. Further well designed, prospective studies are needed to determine how to maximise the impact of physicians within a vascular service to improve patient outcomes while using hospital resources effectively.

Technological advances over the past century have accelerated the pace and breadth of medical and surgical care. From the initial delivery of "telemedicine" over the radio in the 1920s, the delivery of medicine and surgery in the 21st century is no longer limited by connectivity. The COVID-19 pandemic hastened the uptake of telemedicine to ensure that health care can be maintained despite limited face-to-face contact. Like other areas of medicine, vascular surgery has adopted telemedicine, although its role is not well described in the literature. This narrative review explores how telemedicine has been delivered in vascular surgery. Specific themes of telemedicine are outlined with real-world examples, including consultation, triaging, collaboration, mentoring, monitoring and surveillance, mobile health, and education. This review also explores possible future advances in telemedicine and issues around equity of care. Finally, important ethical considerations and limitations related to the applications of telemedicine are outlined. [ABSTRACT FROM AUTHOR]

Extended reality has brought new opportunities for medical imaging visualization and analysis. It regroups various subfields, including virtual reality, augmented reality, and mixed reality.

Virtual assistants, broadly defined as digital services designed to simulate human conversation and provide personalized responses based on user input, have the potential to improve health care by supporting clinicians and patients in terms of diagnosing and managing disease, performing administrative tasks, and supporting medical research and education. These tasks are particularly helpful in vascular surgery, where the clinical and administrative burden is high due to the rising incidence of vascular disease, the medical complexity of the patients, and the potential for innovation and care advancement. The rapid development of artificial intelligence, machine learning, and natural language processing techniques have facilitated the training of large language models, such as GPT-4 (OpenAI), which can support the development of increasingly powerful virtual assistants. These tools may support holistic, multidisciplinary, and high-quality vascular care delivery throughout the pre-, intra-, and postoperative stages. Importantly, it is critical to consider the design, safety, and challenges related to virtual assistants, including data security, ethical, and equity concerns. By combining the perspectives of patients, clinicians, data scientists, and other stakeholders when developing, implementing, and monitoring virtual assistants, there is potential to harness the power of this technology to care for vascular surgery patients more effectively. In this comprehensive review article, we introduce the concept of virtual assistants, describe potential applications of virtual assistants in vascular surgery for clinicians and patients, highlight the benefits and drawbacks of large language models, such as GPT-4, and discuss considerations around the design, safety, and challenges associated with virtual assistants in vascular surgery.

Natural language processing is a subfield of artificial intelligence that aims to analyze human oral or written language. The development of large language models has brought innovative perspectives in medicine, including the potential use of chatbots and virtual assistants. Nevertheless, the benefits and pitfalls of such technology need to be carefully evaluated before their use in health care. The aim of this narrative review was to provide an overview of potential applications of large language models and artificial intelligence chatbots in the field of vascular surgery, including clinical practice, research, and education. In light of the results, we discuss current limits and future directions. [ABSTRACT FROM AUTHOR]

Blood pressure is a critical physiological parameter, particularly in the context of cardiac intensive care and perioperative settings. As a primary indicator of organ perfusion, the maintenance of adequate blood pressure is imperative for the assurance of sufficient tissue oxygen delivery. Among critically ill and major surgery patients, the continuous monitoring of blood pressure is performed as a standard practice for patients. Nonetheless, uncertainties remain regarding blood pressure goals, and there is no consensus regarding blood pressure targets. This review describes the determinants of blood pressure, examine the influence of blood pressure on organ perfusion, and synthesize the current clinical evidence from various intensive care and perioperative settings to provide a concise guidance for daily clinical practice.

Background Early clinical trials validating endovascular therapy (EVT) for emergent large vessel occlusion (ELVO) ischemic stroke in the anterior circulation initially focused on patients with small or absent completed infarctions (ischemic cores) to maximize the probability of detecting a clinically meaningful and statistically significant benefit of EVT. Subsequently, real-world experience suggested that patients with large core ischemic strokes (LCS) at presentation may also benefit from EVT. Several large, retrospective, and prospective randomized clinical trials have recently been published that further validate this approach. These guidelines aim to provide an update for endovascular treatment of LCS. Methods A structured literature review of LCS studies available since 2019 and grading the strength and quality of the evidence was performed. Recommendations were made based on these new data by consensus of the authors, with additional input from the full SNIS Standards and Guidelines Committee and the SNIS Board of Directors. results The management of ELVO strokes with large ischemic cores continues to evolve. The expert panel agreed on several recommendations: Recommendation 1: In patients with anterior circulation ELVO who present within 24 hours of last known normal with large infarct core (70-149 mL or ASPECTS 3-5) and meet other criteria of RESCUE-Japan LIMIT, SELECT2, ANGELASPECT, TESLA, TENSION, or LASTE trials, thrombectomy is indicated (Class I, Level A). Recommendations 2-7 flow directly from recommendation 1. Recommendation 2: EVT in patients with LCS aged 18-85 years is beneficial (Class I, Level A). Recommendation 3: EVT in patients with LCS >85 years of age may be beneficial (Class I, Level B-R). Recommendation 4: Patients with LCS and NIHSS score 6-30 benefit from EVT in LCS (Class I, Level A). Recommendation 5: Patients with LCS and NIHSS score <6 and >30 may benefit from EVT in LCS (Class IIa, Level A). Recommendation 6: Patients with LCS and low baseline mRS (0-1) benefit from EVT (Class I, Level A). Recommendation 7: Patients with LCS and time of last known well 0-24 hours benefit from EVT (Class I, Level A). Recommendation 8: It is recommended that patients with ELVO LCS who also meet the criteria for on-label or guideline-directed use of IV thrombolysis receive IV thrombolysis, irrespective of whether endovascular treatments are being considered (Class I, Level B-NR). Conclusions The indications for endovascular treatment of ELVO strokes continue to expand and now include patients with large ischemic cores on presentation. Further prospective randomized studies, including follow-up to assess the population-based efficacy of treating patients with LCS, are warranted. [ABSTRACT FROM AUTHOR]

The liver requires careful handling intra‐operatively owing to its vital functions and complexity. Traditional open hepatectomy, while standard, is invasive and requires long recovery periods. Laparoscopic hepatectomy is a less invasive option, with its own challenges. The rise of robotic surgery, such as the da Vinci® system, improves precision and control, addressing the limitations of conventional methods, but brings new concerns, such as costs and training. This review focuses on the latest advancements in robotic hepatectomy from 2022/23 articles, delving into topics like "robotic surgery in liver transplantation," "robotic hepatectomy for hilar cholangiocarcinoma," "robotic vascular reconstruction following hepatectomy," "robotic repeat hepatectomy," and "prospective trials in robotic hepatectomy." To retrieve articles, a focused literature search was conducted using PubMed for articles from 2022/23 with a 5‐year filter, excluding reviews. Initially, abstracts were screened, and relevant articles on robotic surgery were examined in full for inclusion in this review. Although all the above items are cutting‐edge, and many of the references are necessarily at the level of case reports, recent articles are still accompanied by surgical videos, which are useful to readers, especially surgeons who are considering imitating the procedures. In summary, we examined the recent advancements in robotic liver resection. The inclusion of videos that present new techniques aids in knowledge transfer. We anticipate the continued growth of this field of research. [ABSTRACT FROM AUTHOR]

Background: Due to its distinct vascular tropism, Campylobacter fetus is recognized as a significant cause of severe systemic infections, especially in immunocompromised individuals, while it is rarely reported as a cause of gastrointestinal infections. Methods: A rare case of mycotic abdominal aortic aneurysm associated with Campylobacter fetus detected on the aneurysm wall itself was described. Results: A 68-year-old male was admitted to the hospital due to severe abdominal pain. The patient was afebrile, hemodynamically stable with elevated C-reactive protein levels. A physical examination revealed a palpable, pulsatile, tender mass located in the periumbilical region. Ultrasonography and multi-slice computer tomography angiography (MSCTA) identified an infrarenal abdominal aortic aneurysm with a maximum diameter of 6.5 cm, showing suspicious signs of dissection. Aneurysmectomy with Dacron tube graft interposition was performed. Although the blood cultures remained negative, the culture of the aneurysmal wall grew Campylobacter fetus, enabling early diagnosis and targeted antibiotic therapy. The patient was treated with meropenem for two weeks, followed by amoxicillin-clavulanate for another two weeks after hospital discharge. Conclusions: Campylobacter fetus associated with abdominal aortic aneurysms represents a life-threatening condition, posing a significant challenge in vascular surgery. Due to the lack of clear guidelines on antibiotic susceptibility testing and the treatment of infections associated with this pathogen, enhanced surveillance of Campylobacter fetus is necessary in both human and veterinary medicine.

We present the case of a 23-year-old woman who reported weakness in the left upper limb, decreased warmth, numbness in the fingers, pain in the clavicular region, and a severe cold sensation in the limb. A thermal imaging camera examination was performed for diagnostic purposes, which guided further diagnostic and therapeutic management towards arterial thoracic outlet syndrome (aTOS). Following surgery and rehabilitation procedures, significant remission of symptoms was achieved and the patient's condition improved. This is the first report on the diagnosis of aTOS using thermal imaging, paving the way for further clinical research into this effective, rapid, and radiation-free method of diagnostic imaging. Conclusion: Thermal imaging is one of the most effective, readily available, and patient-safe methods for diagnosing vascular disease associated with flow disruption. [ABSTRACT FROM AUTHOR]

Calcification of the lower extremities arteries is an unfavorable factor for vascular surgery. Extensive lesions of the femoral segment are an indication for femoropopliteal bypass surgery. Calcification of the femoral arteries complicates the construction of a proximal anastomosis because it precludes clamping the arteries. In addition to technical difficulties in the construction of an anastomosis, significant calcification increases the risks of bleeding and embolic complications and the duration of surgery. In cases of total calcification of the femoral and iliac arteries, balloon occlusion during the construction of an anastomosis makes it possible to occlude the arteries without clamping, which reduces the risks of perioperative complications. We report a case of femoropopliteal bypass surgery in a patient with total calcification of the iliofemoral segment and occlusion of the superficial femoral artery.

Abstract Background and objectives Considering the absence of integrated vascular surgery residency programs in Saudi Arabia, and the need for planning training pathways, we aim to identify how many medical students are interested in vascular surgery, and the factors affecting students’ opinions on pursuing vascular surgery. Materials and Methods: A cross-sectional study was conducted using an online questionnaire that was distributed to medical students nationwide via social media and email. Data were collected from 13 February 2022 to 1 March 2022. Results: A total of 408 students participated. Among them, 152 students were interested in general surgery, of which 103 were considering vascular surgery as a possible future fellowship. However, only 29 out of 408 (7.1%) students picked vascular surgery as their 1st choice. The main motivating factors for students to pursue vascular surgery as a career were: an interest in vascular cases (cardiovascular science), the use of emerging technologies, and the endovascular capabilities of vascular surgeons. The negative factors were simply a preference for another specialty, followed by a lack of experience in vascular surgery. Conclusion: This study reveals that only 7.1% of students consider vascular surgery their first choice. Both the lack of vascular surgeons and students’ experience in vascular surgery affected awareness levels. Interaction with vascular surgeons through virtual rotations for under-served medical schools and the introduction of vascular sciences within the cardiology blocks during basic science years are recommended strategies.

Objectives: We developed a new simulator for hands-on teaching of vascular surgical skills, the Leipzig Latex Patch Model (LPM). This study aimed to quantify the effectiveness and acceptance of the LPM evaluated by students, as well as evaluation of the results by experienced vascular surgeons. Methods: A prospective, single-center, single-blinded, randomized study was conducted. Fifty 5th-year medical students were randomized into two groups, first performing a patch suture on the LPM (study group) or established synthetic tissue model (control), then on porcine aorta. The second suture was videotaped and scored by two surgeons using a modified Objective Structured Assessment of Technical Skill (OSATS) score. We measured the time required for suturing; the participants completed questionnaires. Results: Participants required significantly less time for the second suture than the first (median: LPM 30 min vs. control 28.5 min, p = 0.0026). There was no significant difference in suture time between the groups (median: 28 min vs. 30 min, p = 0.2958). There was an increase in confidence from 28 % of participants before to 58 % after the course (p

Brain arteriovenous malformations (AVM) present complex treatment decisions, particularly for low-grade AVM where surgical resection is often considered the standard. This case report emphasizes the importance of patient preferences and cultural considerations in selecting endovascular embolization over traditional surgical approaches for Spetzler-Martin Grade I AVM management, highlighting the evolving practice of patient-centered care in neurointervention. A 30-year-old male presented with recurrent seizures, characterized by a sudden onset of headache followed by speech arrest, without any preceding medical history of neurological deficits. Initial physical examination revealed no focal neurological deficits. Non-contrast computed tomography, magnetic resonance imaging, and magnetic resonance angiography suggested an AVM involving the cortical-subcortical regions of the left frontal lobe, measuring approximately 1.7 × 2.6 × 1.5 cm, fed by the left middle cerebral artery M3 segment, and draining into the superior sagittal sinus. Spetzler-Martin Grade I classification was confirmed via digital subtraction angiography. Given the patient's strong preference against invasive procedures, driven by personal and cultural beliefs, endovascular embolization was selected as the treatment strategy. Post-embolization, the patient showed marked symptomatic improvement with no evidence of residual AVM on follow-up imaging, and no postprocedure complications were reported. This case highlights the importance of considering patient preferences in AVM treatment planning, illustrating that endovascular embolization can be an effective and less invasive alternative to surgery in selected patients, reinforcing the need for personalized, patient-centered approaches in neurointerventional care.

Background: Extracranial carotid artery aneurysm (ECAA) is a rare condition, with varied symptoms and etiology. The current series describes the profile and treatment outcomes of those with ECCA. Materials and Methods: A record-based retrospective case study on 10 years of data from a hospital was done. Data on sociodemography including age and gender, symptoms, examination findings, radiological investigations, and management techniques were collected. Results: A case series of 12 cases presenting with different symptoms of extracranial internal carotid artery aneurysm are discussed. Age of the participants varied from being adolescents, adults, or elderly patients. Three-fourth of the cases were males. Pulsatile swelling in the neck was the most common presentation, though asymptomatic manifestations are also present. All 12 were managed by different techniques, with surgical resection and end-to-end anastomosis being the most common type of repair. All had good outcomes following treatment. Conclusion: ECCA has male predominance and occurs mainly in those above 50 years of age. The most common presentation is swelling in the neck and the most common management technique is open surgical repair.

The objective was to study the occurrence of perioperative cardiovascular complications (CVС) and clinical and laboratory cardioprotection signs in patients treated with phosphocreatine infusion in intraoperative period of vascular surgery.Materials and methods. The study involved 204 patients with high cardiac risk (revised cardiac risk index > 2, risk of perioperative myocardial infarction or cardiac arrest > 1%) who underwent elective vascular surgery. The patients were randomly divided into two groups. Group I patients received intraoperative infusion of phosphocreatine at a dose of 75.9 [69.8–85.7] mg/kg during 120.0 [107.1–132.0] min. Group II was a control group. The occurrence of CVC, the blood level of the cardiospecific troponin I (cTnI) and N-terminal segment of natriuretic B-type prohormone (NT-proBNP) were analyzed. The data were statistically processed, using the Fisher’s exact test, Mann–Whitney test and logistic regression.Results. Perioperative CVС were recorded in 5 (4.9%) patients in group I and in 18 (17.6%) patients in group II (p = 0.007). Intraoperative administration of phosphocreatine was associated with a reduced risk of CVС: OR 0.2405, 95% CI 0.0856–0.6758, p = 0.007. The cTnI level in patients of groups I and II was 0.021 [0.016–0.030] and 0.019 [0.011–0.028] ng/ml (p = 0.102) before surgery, 0.025 [0.020–0.036] and 0.022 [0.015–0.039] ng/ml (p = 0.357) after surgery, 0.025 [0.020–0.031] and 0.028 [0.018–0.033] ng/ml (p = 0.531) before discharge from the hospital. At the same stages, the level of NT-proBNP was 233.5 [195.0–297.5] and 237.8 [171.3–310.1] pg/ml (p = 0.404), 295.5 [257.3–388.0] and 289.0 [217.5–409.5] pg/ml (p = 0.226), 265.5 [204.8–348.5] and 259.6 [171.0–421.6] pg/ml (p = 0.369).Conclusion. In patients with high cardiac risk undergoing vascular surgery, intraoperative phosphocreatine infusion at a total dose of 75.9 [69.8–85.7] mg/kg reduces the risk of perioperative CVC per 24%. Administration of phosphocreatine to patients with high cardiac risk during vascular surgery does not affect perioperative cTnI and NT-proBNP blood levels.

Objective: The aim of this article is to determine the predictive value of the leukocyte-glycemic index in the long-term evolution of diabetic patients with peripheral arterial disease following endovascular treatment.

Although robot-assisted surgical procedures using the da Vinci robotic system (Intuitive Surgical, Sunnyvale, CA) have been performed in more than 13 million procedures worldwide over the last two decades, the vascular surgical community has yet to fully embrace this approach (Intuitive Surgical Investor Presentation Q3 (2023) https://investor.intuitivesurgical.com/static-files/dd0f7e46-db67-4f10-90d9-d826df00554e. Accessed February 22, 2024). In the meantime, endovascular procedures revolutionized vascular care, serving as a minimally invasive alternative to traditional open surgery. In the pursuit of a percutaneous approach, shorter postoperative hospital stay, and fewer perioperative complications, the long-term durability of open surgical vascular reconstruction has been compromised (in Lancet 365:2179–2186, 2005; Patel in Lancet 388:2366–2374, 2016; Wanhainen in Eur J Vasc Endovasc Surg 57:8–93, 2019). The underlying question is whether the robotic-assisted laparoscopic vascular surgical approaches could deliver the robustness and longevity of open vascular surgical reconstruction, but with a minimally invasive delivery system. In the meantime, other surgical specialties have embraced robot-assisted laparoscopic technology and mastered the essential vascular skillsets along with minimally invasive robotic surgery. For example, surgical procedures such as renal transplantation, lung transplantation, and portal vein reconstruction are routinely being performed with robotic assistance that includes major vascular anastomoses (Emerson in J Heart Lung Transplant 43:158–161, 2024; Fei in J Vasc Surg Cases Innov Tech 9, 2023; Tzvetanov in Transplantation 106:479–488, 2022; Slagter in Int J Surg 99, 2022). Handling and dissection of major vascular structures come with the inherent risk of vascular injury, perhaps the most feared complication during such robotic procedures, possibly requiring emergent vascular surgical consultation. In this review article, we describe the impact of a minimally invasive, robotic approach covering the following topics: a brief history of robotic surgery, components and benefits of the robotic system as compared to laparoscopy, current literature on "vascular" applications of the robotic system, evolving training pathways and future perspectives.
