Abstract
OBJECTIVE Inframalleolar disease is present in most diabetic patients presenting with tissue loss. Inframalleolar (pedal) artery disease and pedal medial arterial calcification (pMAC) are associated with major amputation in patients with chronic limb-threatening ischemia (CLTI). This study aimed to examine the impact of pMAC on the outcomes after isolated inframalleolar (pedal artery) interventions. METHODS A database of lower extremity endovascular intervention for patients with tissue loss between 2007 and 2022 was retrospectively queried. Patients with CLTI were selected, and those undergoing isolated inframalleolar intervention on the dorsalis pedis and medial and lateral tarsal arteries and who had foot x-rays were identified. X-rays were assessed blindly for pMAC and scored on a scale of 0 to 5. Patients with concomitant superficial femoral artery and tibial interventions were excluded. Intention to treat analysis by the patient was performed. Amputation-free survival (survival without major amputation) was evaluated. RESULTS A total of 223 patients (51% female; 87% Hispanic; average age, 66 years; 323 vessels) underwent isolated infra-malleolar intervention for tissue loss. All patients had diabetes, 96% had hypertension, 79% had hyperlipidemia, and 63% had chronic renal insufficiency (55% of these were on hemodialysis). Most of the patients had Wound, Ischemia, and foot Infection (WIfI) stage 3 disease and had various stages of pMAC: severe (score = 5) in 48%, moderate (score = 2-4) in 31%, and mild (score = 0-1) in 21% of the patients. Technical success was 94%, with a median of one vessel treated per patient. All failures were in severe pMAC. Overall, major adverse cardiovascular events was 0.9% at 90 days after the procedure. Following the intervention, most patients underwent a planned forefoot amputation (single digit, multiple digits, ray amputation, or trans-metatarsal amputation). WIfI ischemic grade was improved by 51%. Wound healing at 3 months was 69%. Those not healing underwent below-knee amputations. The overall 5-year amputation-free survival rate was 35% ± 9%. The severity of pMAC was associated with decreased AFS. CONCLUSIONS PMAC influences the technical and long-term outcomes of infra-malleolar intervention in diabetes. Severe pMAC is associated with amputation and should be considered as a variable in the shared decision-making of diabetic patients with CLTI.

Abstract
OBJECTIVE Failure to achieve timely arteriovenous fistulae (AVFs) utilization due to excessive depth (>6 mm) remains an ongoing concern for dialysis access. This study evaluates the outcomes of radiocephalic (RCF) and brachiocephalic (BCF) fistula elevation required for access utilization. METHODS A retrospective review of all patients undergoing first-time autologous access over 10 years was undertaken. RCF and BCF were analyzed, and cases of initial access failure due to depth alone were selected for study. Primary and staged brachio-basilic AVF were excluded. Outcomes of early thrombosis, line placement, maturation (successful progression to hemodialysis [HD∖), reintervention, and functional dialysis (continuous HD for 3 consecutive months) were examined. RESULTS From January 2012 to December 2022, 1733 patients (67% female; mean age, 61 ± 14 years) underwent autologous AVF placement. Of these, 298 patients (17%) had depth-related AVF access issues (BCF, 71% and RCF, 29%). Nineteen percent of these AVFs underwent a primary balloon-assisted maturation (BAM), and 2% had side branch coil embolization before consideration for elevation. The average time to intervention for depth was 11 ± 4 weeks after primary creation. During elevation, side branch ligation occurred in 38% of cases, and 15% underwent intraoperative BAM, The pre-elevation depth was 8.2 ± 3.1 mm, and the mean post-elevation depth was 4.7 ± 2.9 mm (P = .002). Early thrombosis (<18 days) occurred in 4% of cases. There was no mortality, and the 30-day major adverse cardiac event rate was 2%, with a 30-day morbidity of 5%, which was driven by wound issues. Six percent of the AVFs underwent follow-up BAM within 3 months. Mean maturation of the AVFs was 74% ± 3% vs 72% ± 3% (P = .58) for the elevation vs no-elevation groups at 24 weeks, respectively. However, there was an increase in tunneled central line placement in pre-emptive fistula patients due to the delay in maturation (elevation, 17% vs no-elevation, 8%; P = .008). There was a mean successful access time of 6 ± 3 weeks after elevation (16 ± 4 weeks after access creation). There was a median of 2.4 secondary interventions per year after elevation compared with a median of 2.7 secondary interventions per year without elevation. Mean access functionality was 68% ± 8% vs 75% ± 8% at 3 years for the elevation vs no-elevation groups, respectively (P = .25). CONCLUSIONS Elevation of deep BCF and RCF occurs late after placement but can be successfully achieved with low morbidity and satisfactory long-term functionality. It results in an increase in tunneled central line placement in pre-emptive fistula patients. Elevation is a valuable adjunct to AVF maturation and enhances an autologous access policy.

Abstract
BACKGROUND Massive pulmonary embolism (MPE) carries significant 30-day mortality risk, and a change in societal guidelines has promoted the increasing use of extracorporeal membrane oxygenation (ECMO) in the immediate management of MPE-associated cardiovascular shock. This narrative review examines the current status of ECMO in MPE. METHODS A literature review was performed from 1982 to 2022 searching for the terms "Pulmonary embolism" and "ECMO," and the search was refined by examining those publications that covered MPE. RESULTS In the patient with MPE, veno-arterial ECMO is now recommended as a bridge to interventional therapy. It can reliably decrease right ventricular overload, improve RV function, and allow hemodynamic stability and restoration of tissue oxygenation. The use of ECMO in MPE has been associated with lower mortality in registry reviews, but there has been no significant difference in outcomes between patients treated with and without ECMO in meta-analyses. Applying ECMO is also associated with substantial multisystem morbidity due to systemic inflammatory response, bleeding with coagulopathy, hemorrhagic stroke, renal dysfunction, and acute limb ischemia, which must be factored into the outcomes. CONCLUSIONS The application of ECMO in MPE should be combined with an aggressive interventional pulmonary interventional program and should strictly adhere to the current selection criteria.

Abstract
BACKGROUND One-third of American adults encompassed by current colorectal cancer screening guidelines fail to obtain recommended screening evaluations. Educational videos are a valuable medium through which to educate and encourage recommended health behaviors in patients. METHODS A cross-sectional study reviewing the quality of patient education videos addressing colorectal cancer screening. Video quality was assessed in 3 domains: accountability, content, and production. RESULTS Forty-four videos met inclusion criteria. Out of 33 possible points, videos scored a median of 15.0 (interquartile range 12.9-16.6). Videos scored 1.0 (interquartile range .8-1.0) out of 4.0 for accountability, 6.0 (interquartile range 4.4-8.0) out of 20 for content, and 8.0 (interquartile range 7.4-8.0) out of 9.0 for production. Colonoscopy was the most frequently discussed method of screening (38, 86%). While 13 (34%) videos discussed the risk of colorectal cancer in the general population and 15 (32%) discussed the risk in those with a family history, few videos addressed those with other risk factors. Most (31, 70%) videos discussed the medical consequences of not receiving screening, but only 1 (2%) video discussed the social consequences. Similarly, medical benefits were discussed in 34 (77%) videos while other benefits were not discussed by any video. Only one-fifth of the videos address three or more barriers to screening. CONCLUSIONS Videos on colorectal cancer screening have excellent production quality but need improvement in the domains of accountability and content. The videos included in this analysis did not adequately address the concerns of viewers nor the benefits of colorectal cancer screening.

Abstract
BACKGROUND Arteriovenous accesses develop aneurysms (FA) during their active use, resulting in pain, erosion, bleeding, and difficulty in cannulation. This study aims to evaluate the outcomes of open and endovascular management of single FA in arteriovenous fistulas (AVF). METHODS A retrospective review of all upper extremity primary AVFs over 12 years was undertaken at a single center. Patients undergoing elective open and endovascular repair of a single FA were identified. Thirty-day outcomes, cannulation failure, line placement, re-intervention, and functional dialysis (continuous hemodialysis) for 3 consecutive months were examined. RESULTS Three hundred and seventy nine patients presented with a single FA that met the requirements for intervention: 126 (33%) underwent endovascular repair, and the remainder 253 (67%) underwent open repair. Preoperative fistulogram identified anatomically significant issues in 91% of the cases, and these were treated by balloon angioplasty: 10% within the fistula tract, 44% within the outflow tract, and 47% in the central veins. In open repair, 57% underwent plication, 35% underwent resection and re-anastomosis, and the remainder (8%) underwent interposition grafting. In endovascular repair, successful placement of a stent was achieved in all cases with 1 ± 2 (mean ± standard deviation [SD]) covered stents (diameter: 6 -8 mm) placed, achieving successful exclusion of the FA. The combination of early thrombosis and cannulation failures led to the greater need for a tunneled central line in endovascular repair (6.5% vs. 2.4%; endovascular versus open repair; P = 0.04). As a result, the mean time for establishing renewed access in the index AVF was significantly higher in endovascular repair (2 ± 3 vs. 2 ± 2 weeks, mean ± SD; endovascular open repair versus open repair; P = 0.001). In follow-up, there were more secondary interventions per year in the endovascular compared to open repair groups (3.1 vs. 1.4 secondary interventions per year; endovascular versus open repair; P = 0.04). Median functional dialysis durations were superior in the open repair (48 ± 6%, mean + standard error) compared to the endovascular repair at 5 years. (26 ± 7%; P = 0.03). CONCLUSIONS Open repair results in a more rapid return to access use, lower need for a tunneled central line, lower secondary re-intervention rates, and superior functional dialysis durations compared to endovascular repair. Open FA repair should be considered for symptomatic single FA repairs before endovascular FA repair.

Abstract
OBJECTIVE Maintenance of long-term arteriovenous access is important in long-term care for patients with end-stage renal disease. Arteriovenous access is associated in the long term with the development of fistula aneurysms (FAs). This study aims to evaluate the outcomes of staged FA treatment in dialysis access arteriovenous fistulae (AVF). METHODS A retrospective review of all patients over a 12-year period with primary autogenous AVF was undertaken at a single center. Patients undergoing elective open aneurysm repair were identified and were categorized into three groups: single FA repair (single, control group) and staged and unstaged repair of two FAs (staged and unstaged). A staged repair was a procedure in which the initial intent was to treat both aneurysms in the AVF and in which the most symptomatic aneurysm was treated first. When the incision from the first surgery had healed, the second symptomatic aneurysm in the AVF was treated. An unstaged repair was a procedure in which the initial intent was to repair both symptomatic aneurysms simultaneously. All patients had a fistulogram before the FA repair. Thirty-day outcomes, cannulation failure, line placement, reintervention, and functional dialysis (continuous hemodialysis for 3 consecutive months) were examined. RESULTS Five hundred twenty-seven patients presented with FA that met requirements for open intervention; 44% underwent single FA repair, whereas the remaining 34% and 22% underwent staged and unstaged repair of two FAs, respectively. The majority of patients were diabetic and Hispanic. Ninety-one percent of the patients required percutaneous interventions of the outflow tract (37%) and the central veins (54%). Thirty-day major adverse cardiovascular events were equivalent across all modalities. Thirty-day morbidity and early thrombosis (<18 days) were significantly higher in the unstaged group (4.3%) compared with the two other groups (1.3% and 2.1%, single and staged, respectively), which led to an increased need for a short-term tunneled catheter (8.9%) compared with the two other groups (3.4% and 4.4%, single and staged, respectively), Unstaged repair resulted in an increased incidence of secondary procedures (5.0%) compared with the two other groups (2.6% and 3.1%, single and staged, respectively). Functional dialysis at 5 years was equivalent in the single and staged groups but was significantly decreased in the unstaged group. CONCLUSIONS Open interventions are successful therapeutic modalities for FAs, but unstaged rather than staged repair of two concurrent FAs results in a higher early thrombosis, an increased secondary intervention rate, and a need for a short-term tunneled central line. Staged and single FA repairs have equivalent results. In the setting of two symptomatic FAs, staged repair is recommended.

Abstract
Approximately 3% of all patients presenting with Thoracic Outlet Syndrome have a venous etiology (vTOS), which is considered "effort thrombosis". These patients will present with symptomatic deep venous thrombosis or focal subclavian vein (SCV) stenosis. Endovascular management of vTOS occurs in several phases: diagnostic, preoperative therapeutic intervention before decompression, postoperative interventions after decompression, and delayed interventions in the follow-up after decompression. In the diagnostic phase, dynamic SCV venography can establish functional vTOS. Approximately 4,000 patients have been treated for vTOS and reported in the literature since 1970. Declotting of the SCV was followed by surgical decompression in 53% of patients, while in the remainder, surgical decompression alone (18%), endovascular intervention alone (15%), or conservative therapy with anticoagulation (15%) was performed. The initial intervention was predominantly catheter-directed thrombolysis, with <10% of cases undergoing concomitant balloon angioplasty. 93% of cases were successful. In the postoperative phase, balloon angioplasty was performed to correct residual intrinsic SCV disease after vTOS decompression in under 15% of cases. Stents were rarely deployed. Symptom relief was reported as 94 ± 12% (mean ± SD) and 90 ± 23%, respectively for declotting with decompression and declotting alone. In the delayed phase, balloon angioplasty was performed in under 15% of cases to re-establish patency.

Abstract
OBJECTIVE YouTube® has gained popularity as an unofficial educational resource for surgical trainees, but its content's quality and educational value remain to be evaluated. The aim of this study is to analyze the current content on these techniques for lower extremity DVT (LEDVT) on YouTube®. METHODS A search was performed on YouTube® using 13 search terms in August 2022 on a clear-cached browser. Open-access videos focusing on the surgical techniques of venous thrombolysis or thrombectomy for LEDVT were included. Quality and educational value were assessed and graded based on metrics for accountability (4 items), content (13 items), and production (9 items). RESULTS Out of 138 videos regarding LEDVT oriented towards medical professionals, only 14 met inclusion criteria. Videos ran for a median of 3.4 min (range 0.37-35.6 min) with a median of 941 views (range 106-54624). Videos scored a median of 5.5 (range 1.0-8.0) out of 11 for content, a median of 2.0 out of 6.0 (range 0.0-2.0) for accountability, and a median of 5.5 out of 9.0 (range 3.0-9.0) for production. CONCLUSION Few YouTube® videos focus on the technical aspects of DVT thrombolysis/thrombectomy, and they vary significantly in content with overall poor accountability and production quality.

Abstract
Massive pulmonary embolism (MPE) carries significant 30-day mortality and is characterized by acute right ventricular failure, hypotension, and hypoxia, leading to cardiovascular collapse and cardiac arrest. Given the continued high mortality associated with MPE, there has been ongoing interest in utilizing extracorporeal membrane oxygenation (ECMO) to provide oxygenation support to improve hypoxia and offload the right ventricular (RV) pressure in the belief that rapid reduction of hypoxia and RV pressure will improve outcomes. Two modalities can be employed: Veno-arterial-ECMO is a reliable process to decrease RV overload and improve RV function, thus allowing for hemodynamic stability and restoration of tissue oxygenation. Veno-venous ECMO can support oxygenation but is not designed to help circulation. Several societal guidelines now suggest using ECMO in MPE with interventional therapy. There are three strategies for ECMO utilization in MPE: bridge to definitive interventional therapy, sole therapy, and recovery after interventional treatment. The use of ECMO in MPE has been associated with lower mortality in registry reviews, but there has been no significant difference in outcomes between patients treated with and without ECMO in meta-analyses. Considerable heterogeneity in studies is a significant weakness of the available literature. Applying ECMO is also associated with substantial multisystem morbidity due to a systemic inflammatory response, hemorrhagic stroke, renal dysfunction, and bleeding, which must be factored into the outcomes. The application of ECMO in MPE should be combined with an aggressive pulmonary interventional program and should strictly adhere to the current selection criteria.

Abstract
BACKGROUND Establishing long-term arteriovenous access is an important component in the long-term care of a patient with end-stage renal disease. The increasing frequency of obesity is reported to impact the access management of end-stage renal disease patients. This study aims to evaluate the outcomes of arteriovenous fistulae (AVF) in obese and nonobese patients. METHODS A retrospective review of all patients over ten years with primary autogenous AVF (radiocephalic, brachiocephalic, and brachial-basilic) was undertaken at a single center. Patients were subcategorized by body mass index into nonobese, class I, II, and III obesity. Outcomes of maturation (successful progression to hemodialysis), reintervention, functional dialysis (continuous hemodialysis for 3 consecutive months), and patency were examined. RESULTS From January 1999 to December 2019, 2311 patients (67% female; mean age, 61 ± 15 years) underwent primary AVF placement (12% radiocephalic, 53% brachiocephalic, and 35% brachial basilic). Forty-one percent were nonobese, 29% had class I obesity, 19% had class II obesity, and 11% had class III obesity. The majority of patients were diabetic and Hispanic. The 30-day major adverse cardiovascular event rate was elevated in class II (0.20%) and class III (0.50%) obesity compared with class I obesity (0.15%) and nonobese (0.05%). The 30-day morbidity rate was higher in all classes of obesity (0.5% vs0.3% vs 0.2% vs 0.05% for class III vs class II vs class I obesity and nonobese, respectively). Early thrombosis was significantly increased in class II (9%) and class III obesity (12%) compared with class I obesity (5%) and nonobese (3%). There was a two-fold increase in procedures to effect maturation in class II (51%) and class III (74%) obesity compared with class I obesity (22%) and nonobese (34%). Secondary patency at 3 years was significantly lower in class III (62 ± 4%) and class II (79 ± 3%) compared with class I obesity (87 ± 2%) and nonobese (93 ± 4%). All classes of obesity required significantly more secondary Interventions per year compared with nonobese (3.9 vs 3.1 vs 2.5 vs 1.4 secondary interventions per year for class III vs class II vs class I obesity and nonobese, respectively). CONCLUSIONS Advancing obesity class is associated with an increased number of procedures to achieve AVF maturation and is associated with poorer patency and functionality as the category of obesity advances.

Abstract
BACKGROUND Aberrant subclavian artery (ASA) with or without Kommerell's diverticulum (KD) is a rare anatomic aortic arch anomaly that can cause dysphagia and/or life-threatening rupture. The objective of this study is to compare outcomes of ASA/KD repair in patients with a left versus right aortic arch. METHODS Using the Vascular Low Frequency Disease Consortium methodology, a retrospective review was performed of patients ≥18 years old with surgical treatment of ASA/KD from 2000 to 2020 at 20 institutions. RESULTS 288 patients with ASA with or without KD were identified; 222 left-sided aortic arch (LAA), and 66 right-sided aortic arch (RAA). Mean age at repair was younger in LAA 54 vs. 58 years (P = 0.06). Patients in RAA were more likely to undergo repair due to symptoms (72.7% vs. 55.9%, P = 0.01), and more likely to present with dysphagia (57.6% vs. 39.1%, P < 0.01). The hybrid open/endovascular approach was the most common repair type in both groups. Rates of intraoperative complications, death within 30 days, return to the operating room, symptom relief and endoleaks were not significantly different. For patients with symptom status follow-up data, in LAA, 61.7% had complete relief, 34.0% had partial relief and 4.3% had no change. In RAA, 60.7% had complete relief, 34.4% had partial relief and 4.9% had no change. CONCLUSIONS In patients with ASA/KD, RAA patients were less common than LAA, presented more frequently with dysphagia, had symptoms as an indication for intervention, and underwent treatment at a younger age. Open, endovascular and hybrid repair approaches appear equally effective, regardless of arch laterality.

Abstract
OBJECTIVE This study seeks to evaluate the quality and readability of freely available online patient information resources for deep vein thrombosis (DVT) and pulmonary embolism (PE). METHODS Internet searches were performed for five DVT and PE search terms in July 2020 across three search engines and two metasearch engines. Qualitative content analysis was performed. Readability was assessed using four validated instruments. RESULTS Two hundred fifty websites were identified of which 62 websites met inclusion criteria.Website structure and content were satisfactory (>50% overall score), accountability was mixed between DVT (47%) and PE (56%) sites, while interactivity was poor (<30%). On qualitative content analysis, anticoagulation (95.2%) was the most discussed treatment while the most discussed procedures were IVC filter placement for DVT and thrombolysis for PE. Overall readability was difficult with median level suitable for ages 14-18 years. CONCLUSION Freely available online DVT and PE patient information resources publish appropriate content but have very variable accountability and poor readability for the average patient.

Abstract
BACKGROUND Patients with chronic limb-threatening ischemia (CLTI) and chronic kidney disease (CKD) are at risk of developing renal injury following revascularization. We aimed to compare the risk of adverse renal events following endovascular revascularization (ER) or open surgery (OS) in patients with CLTI and CKD. METHODS A retrospective analysis of the National Surgical Quality Improvement Program (NSQIP) databases (2011-2017) was performed including patients with CLTI and non-dialysis-dependent CKD, comparing ER to OS. The primary outcome was a composite of postprocedural kidney injury or failure within 30 days. Thirty-day mortality, major adverse cardiac and cerebrovascular events (MACCE), amputation, readmission or target lesion revascularization (TLR) were compared using multivariate logistic regression and propensity-score matched analysis. RESULTS A total of 5009 patients were included (ER: 2361; OS: 3409). The risk for the composite primary outcome was comparable between groups (odds ratio [OR]: 0.78, 95% confidence interval (CI): 0.53-1.17) as for kidney injury (n=54, OR: 0.97, 95% CI: 0.39-1.19) or failure (n=55, OR: 0.68, 95% CI: 0.39-1.19). In the adjusted regression, a significant benefit was observed with ER for the primary outcome (OR: 0.60, p=0.018) and renal failure (OR: 0.50, p=0.025), but not for renal injury (OR: 0.76, p=0.34). Lower rates of MACCE, TLR, and readmissions were observed after ER. Thirty-day mortality and major amputation rates did not differ. In the propensity score analysis, revascularization strategy was not associated with renal injury or failure. CONCLUSIONS In this cohort, the incidence of renal events within 30 days of revascularization in CLTI was low and comparable between ER and OR. CLINICAL IMPACT In a cohort of 5009 patients with chronic limb-threatening ischemia and non-end-stage chronic kidney disease (CKD), postprocedural kidney injury or failure within 30 days was comparable between patients submitted to open or endovascular revascularization (ER). Lower rates of major adverse cardiac and cerebrovascular events, target lesion revascularization, and readmissions were observed after endovascular revascularization. Based on these findings, ER should not be avoided due to fear of worsening renal function in CKD patients with chronic limb-threatening ischemia. In fact, these patients benefit more from ER regarding cardiovascular outcomes with no increased risk of kidney injury.

Abstract
OBJECTIVE Prior research on median arcuate ligament syndrome has been limited to institutional case series, making the optimal approach to median arcuate ligament release (MALR) and resulting outcomes unclear. In the present study, we compared the outcomes of different approaches to MALR and determined the predictors of long-term treatment failure. METHODS The Vascular Low Frequency Disease Consortium is an international, multi-institutional research consortium. Data on open, laparoscopic, and robotic MALR performed from 2000 to 2020 were gathered. The primary outcome was treatment failure, defined as no improvement in median arcuate ligament syndrome symptoms after MALR or symptom recurrence between MALR and the last clinical follow-up. RESULTS For 516 patients treated at 24 institutions, open, laparoscopic, and robotic MALR had been performed in 227 (44.0%), 235 (45.5%), and 54 (10.5%) patients, respectively. Perioperative complications (ileus, cardiac, and wound complications; readmissions; unplanned procedures) occurred in 19.2% (open, 30.0%; laparoscopic, 8.9%; robotic, 18.5%; P < .001). The median follow-up was 1.59 years (interquartile range, 0.38-4.35 years). For the 488 patients with follow-up data available, 287 (58.8%) had had full relief, 119 (24.4%) had had partial relief, and 82 (16.8%) had derived no benefit from MALR. The 1- and 3-year freedom from treatment failure for the overall cohort was 63.8% (95% confidence interval [CI], 59.0%-68.3%) and 51.9% (95% CI, 46.1%-57.3%), respectively. The factors associated with an increased hazard of treatment failure on multivariable analysis included robotic MALR (hazard ratio [HR], 1.73; 95% CI, 1.16-2.59; P = .007), a history of gastroparesis (HR, 1.83; 95% CI, 1.09-3.09; P = .023), abdominal cancer (HR, 10.3; 95% CI, 3.06-34.6; P < .001), dysphagia and/or odynophagia (HR, 2.44; 95% CI, 1.27-4.69; P = .008), no relief from a celiac plexus block (HR, 2.18; 95% CI, 1.00-4.72; P = .049), and an increasing number of preoperative pain locations (HR, 1.12 per location; 95% CI, 1.00-1.25; P = .042). The factors associated with a lower hazard included increasing age (HR, 0.99 per increasing year; 95% CI, 0.98-1.0; P = .012) and an increasing number of preoperative diagnostic gastrointestinal studies (HR, 0.84 per study; 95% CI, 0.74-0.96; P = .012) Open and laparoscopic MALR resulted in similar long-term freedom from treatment failure. No radiographic parameters were associated with differences in treatment failure. CONCLUSIONS No difference was found in long-term failure after open vs laparoscopic MALR; however, open release was associated with higher perioperative morbidity. These results support the use of a preoperative celiac plexus block to aid in patient selection. Operative candidates for MALR should be counseled regarding the factors associated with treatment failure and the relatively high overall rate of treatment failure.

Abstract
BACKGROUND As vascular surgery training continues to evolve with the growth of integrated vascular surgery residency (0+5) programs and the consolidation of fellowship programs, optimizing all aspects of the education for vascular surgery trainees, both fellows and 0+5 residents, has become increasingly important. In the present study, we aimed to determine the prevalence, quality, and content of vascular surgery education publications across journals. METHODS Journal websites (n = 26) and PubMed were queried to identify vascular surgery education publications from 2012 to 2021. The publications were organized into 11 content categories: (1) curriculum, (2) simulation, (3) trainee assessment, (4) program evaluation, (5) wellness/burnout, (6) diversity/inclusion, (7) mentorship/career, (8) case outcomes, (9) perceptions of training, (10) social media, and (11) other. Publication interactivity and quality were measured via PlumX data and Medical Education Research Study Quality Instrument scores. The data were analyzed via univariate analysis and linear regression. RESULTS A total of 115 vascular surgery education publications (0.2% [interquartile range (IQR), 0.04%-0.5%] of total publications) were identified from the selected journals. The Journal of Vascular Surgery had the highest proportion (0.8%) of vascular surgery education publications, followed by the Journal of Surgical Education (0.7%) and Annals of Vascular Surgery (0.6%). Vascular surgery journals constituted most (79%) of the publications. Of the authors, 15% (IQR, 0%-25%) had a master's or doctorate degree in education. Senior authors were more often identified as male gender (77%), and more first authors (41%) were identified as female gender. An interactivity analysis showed that there were 10.3 citations (IQR, 12), 33.1 captures (IQR, 34), and 8.4 social media interactions (IQR 14) per publication. The educational quality had a median Medical Education Research Study Quality Instrument score of 11 (IQR, 9-12.5), with 49% of publications having a score greater than the median. Publications on training (44% curriculum and 20% simulation) were significantly more frequent than other topics (P < .001), with no change in the publication content over 10 years (P = .29). The volume of vascular surgery education publications did not change during the study period (P = .13) despite the ongoing changes in the educational environment. CONCLUSIONS Despite the increasing importance placed on vascular surgery education by national vascular societies, publications on vascular surgery education have remained sparse among all journals. Also, the vascular surgery educational content has not changed during the past 10 years, with a primary focus on curriculum and simulation training. Further promotion of vascular surgery educational research is required to increase the quality, volume, and diversity of education publications.

Abstract
Central venous stenotic disease is reported in 7%-40% of patients needing a central venous catheter for dialysis and in 19%-41% of hemodialysis patients who have had a prior central venous catheter. Half of these patients will be asymptomatic. Venous Thoracic Outlet syndrome in hemodialysis (hdTOS) is part of this spectrum of disease. The extrinsic mechanical compression of the subclavian vein at the costoclavicular triangle between the clavicle and 1st rib results in an area of external compression with a predisposition to intrinsic mural disease in the vein. The enhanced flow induced by the presence of a distal arteriovenous access in all patients exacerbates the subclavian vein's response to ongoing extrinsic and intrinsic injury. Repeated endovascular interventions during the maintenance of vascular access accelerates chronic untreatable occlusion of the subclavian vein in the long term. Similar to patients with central venous stenosis, patients with hdTOS can present immediately after access formation with ipsilateral edema or longitudinally with episodes of access dysfunction. hdTOS can be treated in an escalating manner with arteriovenous access flow reduction to <1,500 ml/min, endovascular management, surgical decompression by first rib resection in healthy patients and medial clavicle resection in less healthy patients followed by secondary venous interventions, or finally, a venous bypass. hdTOS represents a complex and evolving therapeutic conundrum for the dialysis community, and additional clinical investigations to establish robust algorithms are required.

Abstract
Pulmonary hypertension is a progressive disease with a poor long-term prognosis and high mortality. Pulmonary artery denervation (PADN) is emerging as a potential novel therapy for this condition. The basis of pursuing a sympathetic denervation strategy has its origins in a body of experimental translation work that has demonstrated that denervation can reduce sympathetic nerve activity in various animal models. This reduction in pulmonary sympathetic nerve activity is associated with a reduction in pathological pulmonary hemodynamics in response to mechanical, pharmacological, and toxicologically induced pulmonary hypertension. The most common method of PADN is catheter-directed thermal ablation. Since 2014, there have been 12 reports on the role of PADN in 490 humans with pulmonary hypertension (311:179; treated: control). Of these, six are case series, three are randomized trials, and three are case reports. Ten studies used percutaneous PADN techniques, and two combined PADN with mitral and/or left atrial surgery. PADN treatment has low mortality and morbidity and is associated with an improved 6-minute walking distance, a reduction in both mean pulmonary artery pressure and pulmonary vascular resistance, and an improvement in cardiac output. These improved outcomes were seen over a median follow-up of 12 months (range 2–46 months). A recent meta-analysis of human trials also supports the effectiveness of PADN in carefully selected patients. Based on the current literature, PADN can be effective in select patients with pulmonary hypertension. Additional randomized clinical trials against best medical therapy are required.

Abstract
BACKGROUND With the move to virtual interviewing, residency websites are an important recruitment resource, introducing applicants to programs across the country and allowing for comparison. Recruitment is highly competitive from a common potential pool between vascular surgery, thoracic surgery, and interventional radiology with the ratio of applicants to positions being highest in interventional radiology, followed by thoracic surgery and lastly vascular surgery, as reported by the National Resident Matching Program. OBJECTIVE The aim of this study is to evaluate the accessibility and availability of online content for those integrated residency programs. METHODS A list of accredited vascular surgery, thoracic surgery, and interventional radiology residencies was obtained from the Accreditation Council for Graduate Medical Education (ACGME) database. Program websites were evaluated by trained independent reviewers (n=2) for content items pertaining to program recruitment and education (scored absent or present). Statistical analysis was performed in R software. RESULTS Of ACGME-accredited programs, 56 of 61 (92%) vascular surgery, 27 of 27 (100%) thoracic surgery, and 74 of 85 (87%) interventional radiology programs had functional websites (P=.12). Vascular surgery websites contained a median of 26 (IQR 20-32) content items, thoracic surgery websites contained a median of 27 (IQR 21-32) content items, and interventional radiology websites contained a median of 23 (IQR 18-27) content items. Two content items considered highly influential to applicant program decisions are procedural experience and faculty mentorship, which were reported at 32% (18/56) and 11% (6/56) for vascular surgery, 19% (5/27) and 11% (3/27) for thoracic surgery, and 50% (37/74) and 15% (11/74) for interventional radiology (P=.008 and P=.75), respectively. Key deficits were work hours, debt management, and curriculum for interventional radiology; resident profiles, sample contracts, and research interests in vascular surgery; and operative experiences and the program director's contact and message for thoracic surgery. Interventional radiology deficits were work hours, and thoracic surgery deficits were procedural experience. Both interventional radiology and thoracic surgery websites lacked information on evaluation criteria and faculty mentorship. CONCLUSIONS This study has uncovered key differences in the availability of online content for residencies recruiting from the same pool of applicants. Thoracic surgery has the most information, followed by vascular surgery, with interventional radiology reporting the least content. In the era of virtual interviewing from the same potential pool of applicants, programs should review and revise their web presence with the aim to increase the availability of online content to attract valuable candidates.

Abstract
Objective Angiosarcoma is a rare malignant vascular tumor, and the management and outcome of this disease are not well-described. The aim of this study was to report the incidence, patient demographics, and outcomes of angiosarcoma based on national data. Methods Data on patients with angiosarcoma were obtained from the Surveillance, Epidemiology, and End Results (SEER) database. Inverse probability treatment weights (IPTW) were used to assess the survival benefit of operation with additional chemo or radiation therapy compared to operation alone. These variables were further compared against patients who did not receive an operation despite being initially offered one. Cox regression was used to assess survival. Statistical analyses were performed on RStudio. Results For this study, 5,135 patients (46% men; median age 69, range 0–102) with angiosarcoma were identified in the SEER database between 1975 and 2016. The age-adjusted incidence rate was 1–4%. Patients were mostly non-Hispanic Caucasian (75.4%). The average tumor size was 4.7 cm, range (.1–98.9). Tumor grades were high at presentation (Grade III 17.2, Grade IV 19, and unknown 50.6%), but half were considered localized tumors. Most patients underwent an operation (66.1%). In 5.6% of patients, the operation was recommended but not performed. The overall 5-year survival was 26.7% (95% CI 25.4–28.1%). IPTW with adjusted Cox proportional hazard model demonstrated worse survival, showing that operation compared to no operation and operation with chemo/radiation compared to operation alone had worse survival between months 0 and 25 but had improved survival after month 25. Conclusions The incidence of angiosarcoma is low and long-term survival is poor. Multimodal therapy in the form of neoadjuvant or adjuvant chemo/radiation therapy offers significant long-term survival benefits over operation alone.

Abstract
OBJECTIVE Integrated vascular surgery residency (VS) programs have increased in popularity and offer an accelerated track compared to the traditional fellowship pathway. We sought to create a simple metric for medical students to better assess the competitiveness of VS training programs compared to general surgery (GS) programs. METHODS GS and VS programs were compared using National Resident Matching Program match data from 2012-2021. Applicant metrics (board scores, research output and experiences, work experiences, and volunteer experiences) from 2015-2019 were obtained using the Association of American Medical Colleges Report on Residents. A competitive index (CI) was created (number of programs ranked per applicant divided by match rate) for each specialty and normalized (NCI) to a value of 1 to improve longitudinal comparisons. NCI and number of programs ranked per applicant were plotted across time and a linear regression was performed to evaluate a ten-year trend. RESULTS The match rate of both specialties was 52% and was similar for GS and VS programs. CI was higher for VS compared to GS (18.4±3.0 vs 14.5±0.4; P<0.001). The number of programs ranked per applicant was higher in VS compared to GS (9.4 vs. 7.7, P<0.05). The linear regression revealed increasing NCI and number of programs ranked per applicant over time for VS programs compared to GS with all R2>0.61 (P<0.001). CONCLUSIONS Matching into a VS programs is becoming increasingly competitive. The average competitive index was approximately 27% higher for VS programs compared to GS programs despite similar match rates. As VS programs continue to evolve, NCI may be a more useful metric for applicants.

Abstract
BACKGROUND Venous arterialization is an upcoming and novel alternative in chronic limb threatening ischemia (CLTI) patients in the absence of standard revascularization options. The aim of this study is to systematically review and analyze outcomes of venous arterialization. STUDY DESIGN A systematic literature search was performed in 5 databases using the PRISMA methodology. Inclusion criteria were English language original research papers on CLTI patients treated with venous arterialization. EXCLUSION CRITERIA absence of CLTI due to atherosclerosis, duplicate study or reporting of patients, meeting abstract only. Quality and risk of bias were evaluated. Meta-analysis was performed using random effects model on articles that have a sample size of equal or greater than 10. RESULTS Twelve studies included 442 patients that underwent treatment for 445 limbs (374 patients and 377 limbs underwent venous arterialization while remainder underwent traditional bypass and served as control subjects). Average age was 66 [18 studies, range 37-91 years], 68% were male [271/366, 15 studies] and 67% diabetic [271/406, 16 studies]). Most limbs (88%, 352/398, 16 studies) had tissue loss. Pooled 30-day mortality was 3.7% (95%-confidence interval [CI] 0.8-6.6%), 30-day morbidity was 15.5% (95%-CI 3.2-27.8%), 30-day major adverse cardiovascular event was 5.2% (95%-CI 1.7-8.6%) and 30-day major adverse limb event was 16.7% (95%-CI 1.5-31.9%). Pooled 1-year limb-salvage rate was 79.0% (95%-CI 68.7-90.7) and 1-year survival rate was 85.7% (95%-CI 76.2-96.4). Studies quality varied significantly across studies. CONCLUSION Venous arterialization has an acceptable a 1-year limb salvage rate of 79%, however, this is based on low levels of evidence. More randomized controlled trials or high-quality cohort studies are needed to further define the effectiveness of this procedure for CLTI.

Abstract
BACKGROUND Websites are an important source of information for fellowship applicants, as they can influence ongoing interest and potential program selection. OBJECTIVE This study aims to evaluate the current state of colorectal fellowship websites. METHODS This cross-sectional study evaluates the quantity and quality of information available on websites of colorectal fellowship programs verified by the Accreditation Council for Graduate Medical Education in 2019. RESULTS A total of 63 colorectal fellowships were included for evaluation. Websites were surveyed for content items that previous studies have found to be influential to program applicants. The 58 (91%) programs with a functional website were evaluated using an information index (calculated as a function of availability of content items concerning education, application, personnel, and benefits) and an interactive index (calculated as a function of accessibility and usability of the webpage). Programs had a median total score of 27.8 (IQR 21.5-34.5) of 79. The median score for the interactive index was 7.5 of 15 and for the information index was 20 of 64. The median scores for website application, education, personnel, and benefits or life considerations were 5, 5.5, 3.3, and 4 of 13, 24, 13, and 14, respectively. There was no difference in total score between programs in different geographical regions (P=.46). CONCLUSIONS Currently, colorectal surgery fellowship program websites do not provide enough content for applicants to make informed decisions. All training programs, regardless of specialty, should evaluate and improve their digital footprint to ensure their websites are accessible and provide the information desired by applicants.

Abstract
OBJECTIVE Stress and burnout due to electronic health record (EHR) technology has become a focus for burnout intervention. The aim of this study is to systematically review the relationship between EHR use and provider burnout. MATERIALS AND METHODS A systematic literature search was performed on PubMed, EMBASE, PsychInfo, ACM Digital Library in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. Inclusion criterion was original research investigating the association between EHR and provider burnout. Studies that did not measure the association objectively were excluded. Study quality was assessed using the Medical Education Research Study Quality Instrument. Qualitative synthesis was also performed. RESULTS Twenty-six studies met inclusion criteria. The median sample size of providers was 810 (total 20 885; 44% male; mean age 53 [range, 34-56] years). Twenty-three (88%) studies were cross-sectional studies and 3 were single-arm cohort studies measuring pre- and postintervention burnout prevalence. Burnout was assessed objectively with various validated instruments. Insufficient time for documentation (odds ratio [OR], 1.40-5.83), high inbox or patient call message volumes (OR, 2.06-6.17), and negative perceptions of EHR by providers (OR, 2.17-2.44) were the 3 most cited EHR-related factors associated with higher rates of provider burnout that was assessed objectively. CONCLUSIONS The included studies were mostly observational studies; thus, we were not able to determine a causal relationship. Currently, there are few studies that objectively assessed the relationship between EHR use and provider burnout. The 3 most cited EHR factors associated with burnout were confirmed and should be the focus of efforts to improve EHR-related provider burnout.

Abstract
Background The internet has become a popular platform for patients to obtain information and to review the health care providers they interact with. However, little is known about the digital footprint of vascular surgeons and their interactions with patients on social media. Objective This study aims to understand the activity of academic vascular surgeons on physician rating websites. Methods Information on attending vascular surgeons affiliated with vascular residency or with fellowships in the Southern Association for Vascular Surgery (SAVS) was collected from public sources. A listing of websites containing physician ratings was obtained via literature reviews and Google search. Open access websites with either qualitative or quantitative evaluations of vascular surgeons were included. Closed access websites were excluded. Ranking scores from each website were converted to a standard 5-point scale for comparison. Results A total of 6238 quantitative and 967 qualitative reviews were written for 287 physicians (236 males, 82.2%) across 16 websites that met the inclusion criteria out of the 62 websites screened. The surgeons affiliated with the integrated vascular residency and vascular fellowship programs in SAVS had a median of 8 (IQR 7-10) profiles across 16 websites, with only 1 surgeon having no web presence in any of the websites. The median number of quantitative ratings for each physician was 17 (IQR 6-34, range 1-137) and the median number of narrative reviews was 3 (IQR 2-6, range 1-28). Vitals, WebMD, and Healthgrades were the only 3 websites where over a quarter of the physicians were rated, and those rated had more than 5 ratings on average. The median score for the quantitative reviews was 4.4 (IQR 4.0-4.9). Most narrative reviews (758/967, 78.4%) were positive, but 20.2% (195/967) were considered negative; only 1.4% (14/967) were considered equivocal. No statistical difference was found in the number of quantitative reviews or in the overall average score in the physician ratings between physicians with social media profiles and those without social media profiles (departmental social media profile: median 23 vs 15, respectively, P=.22; personal social media profile: median 19 vs 14, respectively, P=.08). Conclusions The representation of vascular surgeons on physician rating websites is varied, with the majority of the vascular surgeons represented only in half of the physician rating websites The number of quantitative and qualitative reviews for academic vascular surgeons is low. No vascular surgeon responded to any of the reviews. The activity of vascular surgeons in this area of social media is low and reflects only a small digital footprint that patients can reach and review.

Abstract
The Impella is a percutaneously placed intra-arterial flow pump positioned across the aortic valve for circulatory support. A limitation of the Impella is that it lacks a central wire channel, to maintain intra-arterial wire access when removing the device. Open surgical arterial cutdown is needed for the removal of the Impella CP placed emergently, without the use of preclose sutures. This case review describes an alternative removal method for the aforementioned occasions.

Abstract
BACKGROUND The aim of the present study was to assess the effects of the extent of heel ulceration on the outcomes of limb threatening critical ischemia due to isolated infrapopliteal disease. METHODS A retrospective review identified 989 patients with isolated infrapopliteal disease and heel ulceration treated from 2001 to 2018. The heel was defined as the back of the foot, extending from the Achilles tendon to around the plantar surface and covering the apex of the calcaneum bone. Heel ulceration was categorized into three groups by area: <5 cm2, 5 to 10 cm2, and >10 cm2. The interventions were endovascular, open bypass, major amputation, and wound care. An intention-to-treat analysis by patient group was performed. The 30-day outcomes and amputation-free survival (AFS; survival without a major amputation) were evaluated. RESULTS Of the 989 patients, 384 (58% male; average age, 65 years; n = 768 vessels) had undergone isolated endovascular tibial intervention, 124 (45% male; average age, 59 years) had undergone popliteal tibial vein bypass for limb threatening critical ischemia, 219 (52% male; average age, 67 years) had undergone major amputation, and 242 (49% male; average age, 66 years) had received wound care. No difference was found in the 30-day major adverse cardiac events in the endovascular and open bypass groups, with significantly more events in the major amputation group (P = .03). The 30-day major adverse limb events and 30-day amputation rates were equivalent between the open bypass and endovascular groups. The 5-year AFS rate was superior in the open bypass group (37% ± 8%; mean ± standard error of the mean) compared with the endovascular group (27% ± 9%; P = .04). The wound care group had a 5-year AFS rate of 20% ± 9%, which was not significantly different from that of the endovascular group. Patients with heel ulcers of <5 cm2 had better AFS (47% ± 8%) than those with 5- to 10- cm2 heel ulceration (24% ± 9%). Heel ulcers >10 cm2 were associated with markedly worse 5-year AFS outcomes (0% ± 0%). The presence of end-stage renal disease, osteomyelitis, uncontrolled diabetes (hemoglobin A1c >10%), and/or frailty combined with a heel ulcer >10 cm2 were predictive of poor AFS. CONCLUSIONS An increasing heel ulcer area combined with osteomyelitis and systemic comorbidities was associated with worsening 30-day outcomes and 5-year AFS, irrespective of the therapy chosen.

Abstract
The Society for Vascular Surgery Alternative Payment Model (APM) Taskforce document explores the drivers and implications for developing objective value-based reimbursement plans for the care of patients with peripheral arterial disease (PAD). The APM is a payment approach that highlights high-quality and cost-efficient care and is a financially incentivized pathway for participation in the Quality Payment Program, which aims to replace the traditional fee-for-service payment method. At present, the participation of vascular specialists in APMs is hampered owing to the absence of dedicated models. The increasing prevalence of PAD diagnosis, technological advances in therapeutic devices, and the increasing cost of care of the affected patients have financial consequences on care delivery models and population health. The document summarizes the existing measurement methods of cost, care processes, and outcomes using payor data, patient-reported outcomes, and registry participation. The document also evaluates the existing challenges in the evaluation of PAD care, including intervention overuse, treatment disparities, varied clinical presentations, and the effects of multiple comorbid conditions on the cost potentially attributable to the vascular interventionalist. Medicare reimbursement data analysis also confirmed the prolonged need for additional healthcare services after vascular interventions. The Society for Vascular Surgery proposes that a PAD APM should provide patients with comprehensive care using a longitudinal approach with integration of multiple key medical and surgical services. It should maintain appropriate access to diagnostic and therapeutic advancements and eliminate unnecessary interventions. It should also decrease the variability in care but must also consider the varying complexity of the presenting PAD conditions. Enhanced quality of care and physician innovation should be rewarded. In addition, provisions should be present within an APM for high-risk patients who carry the risk of exclusion from care because of the naturally associated high costs. Although the document demonstrates clear opportunities for quality improvement and cost savings in PAD care, continued PAD APM development requires the assessment of more granular data for accurate risk adjustment, in addition to largescale testing before public release. Collaboration between payors and physician specialty societies remains key.

Abstract
BACKGROUND Inframalleolar disease is present in many diabetic patients presenting with tissue loss. The aim of this study was to examine the patient-centered outcomes after isolated inframalleolar interventions. METHODS A database of patients undergoing lower extremity endovascular interventions for tissue loss (critical limb-threatening ischemia, Wound, Ischemia, and foot Infection [WIfI] stage 1-3) and a de novo intervention on the index limb between 2007 and 2017 was retrospectively queried. Those patients with isolated inframalleolar interventions on the dorsalis pedis and medial and lateral tarsal arteries were identified. Patients with concomitant superficial femoral artery and tibial interventions were excluded. Intention-to-treat analysis by patient was performed. Patient-oriented outcomes of clinical efficacy (absence of recurrent symptoms, maintenance of ambulation, and absence of major amputation), amputation-free survival (AFS; survival without major amputation), and freedom from major adverse limb events (above-ankle amputation of the index limb or major reintervention [new bypass graft, jump or interposition graft revision]) were evaluated. RESULTS There were 109 patients (48% male; average age, 65 years; 153 vessels) who underwent isolated inframalleolar interventions for tissue loss. All patients had diabetes, and 53% had chronic renal insufficiency (47% of these were on hemodialysis). The majority of the patients had WIfI stage 3 disease. Technical success was 81%, with a median of one vessel treated per patient. Thirty-four percent of interventions were a direct revascularization of the intended angiosome in the foot. The 30-day major adverse cardiovascular event rate was 0%. The majority of patients underwent some form of planned forefoot surgery (single digit, multiple digits, ray or transmetatarsal amputation). Wound healing at 3 months in those not requiring amputation was 76%. Predictors for wound healing were improved pedal runoff score (<7), absence of infection, direct angiosome revascularization, and absence of end-stage renal disease. Those in whom the primary wounds or the initial amputation site failed to heal ultimately underwent below-knee amputations. The clinical efficacy was 25% ± 7% (mean ± standard error of the mean) at 5 years. The 5-year AFS rate was 33% ± 8%, and the 5-year freedom from major adverse limb events was 27% ± 9%. On Cox proportional multivariate analysis, predictors for AFS were absence of significant coronary disease, postprocedure pedal runoff score <7 (good runoff), WIfI stage <3, and absence of end-stage renal disease. CONCLUSIONS Inframalleolar intervention can be successfully performed in high-risk limbs with acceptable short-term results. However, long-term AFS remains poor because of the underlying disease process.

Abstract
Tracheoinnominate fistula is a rare but lethal condition that requires emergent surgical intervention to prevent ensuing exsanguinating hemorrhage. In clinical situations where the risk of open surgery is prohibitively high, endovascular repair may provide a life-saving alternative to control hemorrhage and serve as a temporizing or definitive solution based on a given clinical scenario. The authors report successful endovascular repair of the bleeding tracheoinnominate fistula with a stent in a liver transplant patient with high comorbidities and review the current literature.

Abstract
BACKGROUND The 0+5 integrated vascular surgery residency program (IVSR) was introduced as a training model toward board certification in vascular surgery over 10 years ago. The pros and cons of this training model have been debated. OBJECTIVE The purpose of this review is to investigate, using qualitative methods, what is known about the development, implementation, and outcomes of the IVSR paradigm. DESIGN A systematic search of the literature pertaining to the IVSR training model was conducted to include literature from 2005 to 2016. A search strategy involving use of 4 literature databases, 4 search terms, and 4 inclusion criteria was used. Three independent reviewers screened titles and abstracts for inclusion. Data abstraction was performed by 1 reviewer. Qualitative content analysis was completed using the method of constant comparative analysis associated with a grounded theory design by all 3 reviewers. RESULTS Of 890 articles initially identified, 33 articles were found to meet inclusion criteria for full review. Nineteen (57%) were research articles with an average Medical Education Research Study Quality Instrument score of 6.3 out of 18. The remaining articles were categorized as editorials, presidential addresses, invited commentaries, and historical summaries. Three major themes related to the IVSR program were identified: context of program development, processes of the program once implemented, and outcomes. CONCLUSIONS The literature on the IVSR paradigm reflects contextual, process, and outcome issues. Research articles are of generally low quality and there is a paucity of analyses of outcome issues. Further research is recommended to identify and understand the outcomes of the model.

Abstract
BACKGROUND Critical hand ischemia owing to vascular access-induced steal syndrome (VASS) continues to be a significant problem. The aim of this study was to examine the outcomes of arterial endovascular interventions in the upper extremity of patients presenting with VASS. METHODS A database of patients presenting with documented VASS between 2006 and 2016 was retrospectively queried. Patients who underwent isolated endovascular intervention in the upper extremity were analyzed. RESULTS Ninety-eight patients (66% female; average age 65 years) presented with VASS: 28 presented with upper arm atherosclerotic disease above the arteriovenous (AV) anastomosis (above elbow) and the remaining 70 patients with below AV anastomotic atherosclerotic disease at the elbow (below elbow). Sixty-three percent of the entire patient cohort (N = 65) presented with rest pain and the remainder (n = 33 [34%]) with minor digital ulceration. Of those with upper arm disease above the AV anastomosis, one-third of patients had subclavian occlusive disease and two-thirds had brachial artery occlusive disease. Patients with subclavian disease underwent stent placement, and patients with brachial artery disease underwent balloon angioplasty. Technical success was 100% (n = 28). Ninety-one percent of these patients (n = 25) had symptomatic success at 30 days and the remainder (n = 3) required proximalization of the access. Of those with below AV anastomosis at the elbow disease, all had disease in the forearm vessels with 42% (n = 29) having either the ulnar or radial artery occlusion. Balloon angioplasty was performed in one vessel in 55% (n = 38) and in two vessels in 45% (n = 32) of patients. Technical success was 79% (n = 81 of 102 vessels) with 51% of the patients (n = 36) having symptomatic success at 30 days; of those who remained symptomatic, 80% (n = 27) required proximalization of the access and 20% (n = 7) required ligation. The major adverse cardiovascular event rate for the entire patient cohort was 4% (n = 4). The 30-day complications for the entire patient cohort included continued steal (38%; all resolved with secondary procedures), thrombosis (3%; all forearm vessels treated for occlusion), bleeding (0%), infection (0%), and mortality (1%). Primary clinical success defined as the relief of distal ischemic symptoms and the preservation of a functional access site for dialysis showed rates of 42 ± 9% (mean ± standard error of the mean) and 0 ± 0% at 5 years (above and below elbow groups, respectively). CONCLUSIONS Upper extremity interventions for VASS owing to above elbow disease are associated with a high rate of success, whereas interventions for below elbow disease have a poor clinical success with more patients requiring secondary procedures and low long-term survival for the access site. Male patients presenting with rest pain, larger forearm vessels (approximately 3 mm), short occlusive lesions (<100 mm), two-vessel runoff, and an intact palmer arch are good candidates for below elbow interventions.

Abstract
BACKGROUND Critical hand ischemia owing to below-the-elbow atherosclerotic occlusive disease is relatively uncommon. The aim of this study was to examine the outcomes in patients presenting with critical ischemia owing to below-the-elbow arterial atherosclerotic disease who underwent nonoperative and operative management. METHODS A database of patients undergoing operative and nonoperative management for symptomatic below-the-elbow atherosclerotic disease between 2006 and 2016 was retrospectively queried. Patients with critical ischemia (tissue loss and rest pain) were identified. Three management groups were identified: no revascularization (None), endovascular revascularization (Endo), and open revascularization by bypass (Bypass). Patients with acute embolism, active vasculitis, end-stage renal disease, ipsilateral dialysis access complications of steal, and ipsilateral trauma were excluded. RESULTS One hundred eight patients (56% male; average age, 59 years) presented with symptomatic below-the-elbow disease: 93% presented with digital ulceration and the remainder with rest pain. Eighty-one percent had diabetes and 41% had chronic renal insufficiency (not on dialysis). All underwent catheter-based angiography. Fifty-three patients (49%) had no intervention and subsequently were committed to wound care; 26 of these required no further intervention, 10 had an interval palmar sympathectomy, and 17 underwent either a phalanx or digital amputation. Thirty-four patients (31%) underwent an endovascular intervention with a median of 1.5 vessels (ulnar, radial, or interosseous arteries) intervened on. Technical success was achieved in 29 patients (85%). Of the five technical failures, two went on to bypass, one had a focal endarterectomy and patch angioplasty, and one was treated conservatively. Ten patients in the Endo group required either a phalanx or digital amputation. Twenty-one patients (19%) underwent a saphenous vein bypass (reversed or nonreserved) to the radial in 12 and the ulnar in 11 limbs. In follow-up, 11 patients underwent open or endovascular intervention to maintain patency of the bypass. There were nine phalanx or digital amputations in the Bypass group. No below-the-elbow or above-the-elbow amputations were performed within 30 days. The wound healing rate without amputation was 78% (85 of 108). The predictors of wound healing were technical success of the revascularization, intact palmar arch and presence of digital run-off. The presence of an incomplete arch and poor digital run-off were associated with a phalanx or digital amputation. CONCLUSIONS Upper extremity interventions for critical ischemia are associated with a high rate of success. Major amputations are rare and the many can be treated nonoperatively. In appropriately selected patients, both endovascular and open interventions have a high rate of success.

Abstract
OBJECTIVE Advanced renal cell carcinoma (RCC) has a significant predisposition to vascular invasion. Tumor vascular invasion and thrombus are found in the renal vein and the inferior vena cava (IVC) in up to 10% to 25% of patients. This study reviewed the current status of radical nephrectomy with IVC thrombectomy for advanced RCC. METHODS A two-level search strategy of the literature (MEDLINE, PubMed, The Cochrane Library, and Google Scholar) for relevant articles listed between January 2000 and December 2015 was performed. The review was confined to patients with primary RCC associated with vascular invasion. RESULTS Untreated RCC with intravascular thrombus has a median survival of 5 months. Surgical exposure and intervention are tailored to the level of tumor thrombus. The 30-day mortality for radical nephrectomy with IVC thrombectomy is low (1.5%-10%), and the complication rates have been reported to be 18%, 20%, 26%, and 47% for IVC tumor thrombus level I, II, III, and IV disease, respectively. Disease-specific survival ranges from 40% to 60% at 5 years after nephrectomy and removal of the intravascular tumor. CONCLUSIONS Radical nephrectomy with IVC thrombectomy is an effective cancer control operation that can be safely performed with acceptable mortality and morbidity. Preoperative imaging coupled with perioperative surgical management of the IVC is critical to procedural success and patient outcomes.
