Abstract
INTRODUCTION Preoperative anemia has been consistently shown to be a risk factor for acute kidney injury (AKI) after cardiac surgery. However, this association has not been examined in the open abdominal aortic aneurysm repair (OAR) population and is the subject of this analysis. METHODS Targeted Vascular Module from the American College of Surgeons National Surgical Quality Improvement Program was queried for patients undergoing OAR from 2013 to 2019. Anemia was defined according to World Health Organization Guidelines: Hematocrit<36% for women or <39% for men. Primary endpoint was 30-day AKI. Anemia's effect on AKI was determined using inverse probability weighted logistic regression. RESULTS There were 2275 OAR; mean age was 70.9 ± 8.2 y; 24.0% were women. Anemia was present in 498 (26.3%) patients; 165 (7.6%) had a hematocrit<33% and 8 (0.35%) had a hematocrit<24%. Differences in patient factor were nonsignificant after weighting. Any degree of postoperative AKI was more common in the anemia group (11.2% vs 5.1%; unweighted P < 0.001), as was AKI requiring hemodialysis (7.7% vs 3.2%; unweighted P < 0.001). In the weighted multivariable analysis, anemia was independently associated with postoperative AKI (odds ratio 1.51; 95% confidence interval: 1.01-2.26; P = 0.042) while controlling for age and operative factors. Patients with postoperative AKI were significantly more likely to die postoperatively than those without (26.1% vs 1.9%; <0.001). CONCLUSIONS Preoperative anemia was independently associated with post-OAR AKI after propensity weighting and controlling for operative factors. AKI is a major source of morbidity and mortality in these patients, and, if time permits, preoperative correction of anemia or its underlying cause should be considered in high-risk patients.

Abstract
BACKGROUND With increasing regionalization of complex aortic surgery within fewer US centers, patients may face increased travel burden when accessing aortic surgery. Longer travel distances have been associated with inferior outcomes after major surgery; however, the impacts of distance on reinterventions and costs have not been described. This study aims to assess the association between patient travel distance and longer-term outcomes including costs and reinterventions after complex aortic surgery. METHODS A retrospective review was conducted of all patients in the Vascular Implant Surveillance and Interventional Outcomes Network database undergoing complex endovascular aortic repair including internal iliac or visceral vessel involvement, complex thoracic endovascular aortic repair including Zone 0-2 proximal extent or branched devices, and complex open abdominal aortic aneurysm repair including suprarenal or higher clamp sites. Travel distance was stratified by Rural-Urban Commuting Area population-density category. Multinomial logistic regression models, negative-binomial models, and zero-inflated Poisson models were used to assess the association between travel distance and index procedural and comprehensive first-year costs, long-term imaging, and long-term reinterventions, respectively. RESULTS Between 2011 and 2018, 8,782 patients underwent complex aortic surgery in the Vascular Implant Surveillance and Interventional Outcomes Network database, including 4,822 complex endovascular aortic repairs, 2,672 complex thoracic endovascular aortic repairs, and 1,288 complex open abdominal aortic aneurysm repairs. Median travel distance was 22.8 miles (interquartile range 8.6-54.8 miles, range 0-2,688.9 miles). Median age was 75 years for all distance quintiles. Patients traveling farther were more likely to be female (26.8% in quintile 5 [Q5] vs. 19.9% in Q1, P < 0.001) and to have had a prior aortic surgery (20.8% for Q5 vs. 5.9% for Q1, P < 0.001). Patients traveling farther had higher index procedural costs, with adjusted odds ratio (OR) 2.34 (95% confidence interval [CI] 1.86-2.94, P < 0.0001) of being in the highest cost tertile versus lowest for patients in Q5 vs. Q1. For patients with ≥ 1-year follow-up, those traveling farther had higher imaging costs, with adjusted Q5 OR 1.55 (95% CI 1.22-1.95, P = 0.0002), and comprehensive first-year costs, with adjusted Q5 OR 2.06 (95% CI 1.57-2.70, P < 0.0001). In contrast, patients traveling farther had similar numbers of reinterventions and imaging studies postoperatively. CONCLUSIONS Patients traveling farther for complex aortic surgery have higher procedural costs, postoperative imaging costs, and comprehensive first-year costs. These patients should be targeted for increased care coordination for improved outcomes and healthcare system burden.

Abstract
Most kidney cancers are primary renal cell carcinomas (RCC) of clear cell histology. RCC is unique in its ability to invade into contiguous veins - a phenomenon terms venous tumor thrombus. Surgical resection is indicated for most patients with RCC and an inferior vena cava (IVC) thrombus in the absence of metastatic disease. Resection also has an important role in selected patients with metastatic disease. In this review, we discuss the comprehensive management of the patient with RCC with IVC tumor thrombus, emphasizing a multidisciplinary approach to the surgical techniques and perioperative management.

Abstract
OBJECTIVE Recently evolving practice patterns in complex aortic surgery have led to regionalization of care within fewer centers in the United States, and thus patients may have to travel farther for complex aortic care. Travel distance has been associated with inferior outcomes after non-vascular surgery, particularly non-index readmission. This study aims to assess the impact of patient travel distance on perioperative outcomes and readmissions after complex aortic surgery. METHODS A retrospective review was conducted of all patients in the Vascular Quality Initiative and Vascular Implant Surveillance and Interventional Outcomes Network databases undergoing complex endovascular aortic repair (EVAR) including internal iliac or visceral vessel involvement, complex thoracic endovascular aortic repair (TEVAR) including zone 0 to 2 proximal extent or branched devices, and complex open abdominal aortic aneurysm (AAA) repair including suprarenal or higher clamp sites. Travel distance was stratified by rural/urban commuting area (RUCA) population-density category. Wilcoxon and χ2 tests were used to assess relationships between travel distance quintiles and baseline characteristics, mortality, and readmission. Travel distance and other factors were included in multivariable Cox models for survival and Fine-Gray competing risk models for freedom from readmission. RESULTS Between 2011 and 2018, 8782 patients underwent complex aortic surgery in the Vascular Quality Initiative and Vascular Implant Surveillance and Interventional Outcomes Network databases, including 4822 complex EVARs, 2672 complex TEVARs, and 1288 complex open AAA repairs. Median travel distance was 22.8 miles (interquartile range [IQR], 8.6-54.8 miles). Median age was 75 years for all distance quintiles, but patients traveling longer distances were more likely female (26.8% in quintile 5 [Q5] vs 19.9% in Q1; P < .001), white (93.8% of Q5 vs 83.8% of Q1; P < .001), to have larger-diameter AAAs (median 59 mm for Q5 vs 55 mm for Q1; P < .001), and to have had prior aortic surgery (20.8% for Q5 vs 5.9% for Q1; P < .001). Overall 30-day readmission was more common at farther distances (18.1% for Q5 vs 14.8% for Q1; P = .003), with higher non-index readmission (11.2% for Q5 vs 2.7% for Q1; P < .001) and conversely lower index readmission (6.9% for Q5 vs 12.0% for Q1; P < .001). Multivariable-adjusted Fine-Gray models confirmed greater hazard of non-index readmission with farther distance, with a Q5 hazard ratio of 3.02 (95% confidence interval, 2.12-4.30; P < .001). Multivariable-adjusted Cox models demonstrated no association between travel distance and long-term survival but found that non-index readmission was associated with increased long-term mortality (hazard ratio, 1.46; 95% confidence interval, 1.20-1.78; P = .0001). CONCLUSIONS Patients traveling farther for complex aortic surgery demonstrate higher non-index readmission, which, in turn, is associated with increased long-term mortality risk. Aortic centers of excellence should consider targeting these patients for more comprehensive follow-up and care coordination to improve outcomes.

Abstract
OBJECTIVE Despite the progressive advancement of devices for endovascular aortic repair (EVAR), endografts continue to fail, requiring explant. We present a single-institutional experience of EVAR explants, characterizing modern failure modes, presentation, and outcomes for partial and complete EVAR explantation. METHODS A retrospective analysis was performed of all EVARs explanted at an urban quaternary center from 2001 to 2020, with one infected endograft excluded. Patient and graft characteristics, indications, and perioperative and long-term outcomes were analyzed. Partial versus complete explants were performed per surgeon discretion without a predefined protocol. This process was informed by patient risk factors; asymptomatic, symptomatic, or ruptured aneurysm presentation; and anatomical or intraoperative factors, including endoleak type. RESULTS From 2001 to 2020, 52 explants met the inclusion and exclusion criteria. More than one-half (57.7%) were explants of EVAR devices placed at outside institutions, designated nonindex explants. Most patients were male (86.5%), the median age was 74 years (interquartile range, 70-78 years). More than one-half (61.5%) were performed in the second decade of the study period. The most commonly explanted grafts were Gore Excluder (n = 9 grafts), Cook Zenith (n = 8), Endologix AFX (n = 7), Medtronic Endurant (n = 5), and Medtronic Talent (n = 5). Most grafts (78.8%) were explanted for neck degeneration or sac expansion. Five were explanted for initial seal failure, five for symptomatic expansion, and seven for rupture. The median implant duration was 4.2 years, although ranging widely (interquartile range, 2.6-5.1 years), but similar between index and nonindex explants (4.2 years vs 4.1 years). Partial explantation was performed in 61.5%, with implant duration slightly lower, 3.2 years versus 4.4 years for complete explants. Partial explantation was more frequent in index explants (68.2% vs 56.7%). The median length of stay was 8 days. The median intensive care unit length of stay was 3 days, without significant differences in nonindex explants (4 days vs 3 days) and partial explants (4 days vs 3 days). Thirty-day mortality occurred in two nonindex explants (one partial and one complete explant). Thirty-day readmission was similar between partial and complete explants (9.7% vs 5.0%), without accounting for nonindex readmissions. Long-term survival was comparable between partial and complete explants in Cox regression (hazard ratio, 2.45; 95% confidence interval, 0.79-7.56; P = .12). CONCLUSIONS Explants of EVAR devices have increased over time at our institution. Partial explant was performed in more than one-half of cases, per operating surgeon discretion, demonstrating higher blood loss, more frequent acute kidney injury, and longer intensive care unit stays, however with comparable short-term mortality and long-term survival.

Abstract
BACKGROUND With the evolution in vascular surgery toward increased endovascular therapy and decreased open surgical training, comfort with open procedures by current trainees is declining. A proposed method to improve this discomfort is simulator training. We hypothesized that open, cadaver, and endovascular surgery simulation would be associated with increased self-perceived comfort in performing corresponding procedures. METHODS Integrated (0 + 5) vascular surgery residents and recent graduates in the United States were asked to complete a survey quantifying comfort via a Likert scale with procedures and experience with simulation training. Simulation groups were then matched using coarsened exact matching. Ordinal logistic regression assessed the association between simulation experience and comfort in performing procedures. RESULTS Surveys were completed by 68 trainees and 20 attending surgeons in their first 5 years of practice. On unmatched analyses, there were no significant differences in comfort in performing any open or endovascular aorto-mesenteric or peripheral vascular procedures between respondents who reported experience with open or endovascular simulation, respectively. However, respondents who reported cadaver simulation experience (58%, 51/88) had a significantly higher reported comfort score performing open juxtarenal aortic repair (2.4 vs. 1.7), superior mesenteric artery thrombectomy or bypass (2.5 vs. 1.9), inferior vena cava or iliac vein repair (2.2 vs. 1.7), axillary-femoral artery bypass (3.4 vs. 2.5), femoral-popliteal artery bypass (3.7 vs. 2.8), and inframalleolar artery bypass (2.8 vs. 2.1; all P < 0.05). After matching on training level, number of abdominal cases completed, and number of open vascular cases completed, ordinal logistic regression demonstrated that previous cadaver simulation was significantly associated with increased comfort in performing open aortic repairs, venous repair, visceral revascularization, and peripheral bypasses. CONCLUSIONS In this nationally representative sample, cadaver, but not open or endovascular, simulation was associated with increased comfort in performing open vascular surgery. Providing cadaver simulation to trainees may help to improve comfort levels in performing open surgery. Integrated vascular surgery training programs should consider implementing these experiences into their curriculum.

Abstract
BACKGROUND Abdominal compartment syndrome (ACoS) is a devastating complication after endovascular aneurysm repair for ruptured abdominal aortic aneurysms (rEVAR). This study sought to develop a risk score for ACoS to identify patients who would benefit from early decompressive laparotomy. METHODS Model derivation was performed with VQI data for rEVAR from 2013-2020. The primary outcome was evacuation of abdominal hematoma. Multivariable logistic regression was used to create and validate a scoring system to predict ACoS. The model was validated using institutional data for rEVAR from 1998-2019. RESULTS The derivation cohort included 2,310 patients with rEVAR. Abdominal hematoma evacuation occurred in 265 patients (11.5%). Factors associated with abdominal hematoma evacuation on multivariable analysis included transfer from an outside hospital, preoperative creatinine ≥1.4 mg/dl, preoperative systolic blood pressure ≤85 mmHg, preoperative altered mental status, ≥3.0 liters intraoperative crystalloid, and ≥4 units of red blood cells transfused intraoperatively. The validation cohort consisted of 67 rEVAR; ACoS occurred in 8 patients (11.9%). The c-statistic was 0.84 in the derivation and 0.87 in the validation cohort, while Hosmer-Lemeshow was p= 0.15 in the derivation and 0.84 in the validation cohorts, suggesting good model discrimination and calibration. Points were applied based on β-coefficients to produce a risk score ranging from -1 to 13. A cutoff of risk score ≥8 resulted in a sensitivity and specificity of 87.5% and 83.1% for detecting patients with ACoS, respectively. ACoS conveyed a significantly higher mortality in both the derivation (ACoS: 49.8% vs No ACoS: 17.8%; p<0.001) and validation cohorts (ACoS: 75.0% vs No ACoS: 15.2%; p<0.001). CONCLUSION In patients with equivocal signs/symptoms of ACoS, this scoring system can be used to guide surgeons on when to perform decompressive laparotomy prior to leaving the operating room for rEVAR. Patients with a risk score ≥8 would benefit from decompressive laparotomy at index rEVAR.

Abstract
INTRODUCTION The proportion of open aneurysm repairs requiring at least a suprarenal clamp has increased in the past few decades, partly due to preferred endovascular approaches for most patients with infrarenal aneurysms, suggesting that the management of aortic clamp placement has become even more relevant. This study evaluated the association between proximal clamp site and intraoperative ischemia times with postoperative renal dysfunction and mortality. METHODS We used the Vascular Quality Initiative to identify all patients undergoing open repairs of elective or symptomatic juxtarenal AAAs from 2004-2018 and compared outcomes by clamp site: above one renal artery, above both renal arteries (supra-renal), or above the celiac trunk (supra-celiac). Outcomes evaluated included acute kidney injury (AKI), new-onset renal failure requiring renal replacement therapy (RRT), 30-day mortality, and one-year mortality. We used multilevel logistic regressions and cox-proportional hazards models, clustered at the hospital level, to adjust for confounding. RESULTS We identified 3976 patients (median age 71 years, 70% male, 8.2% non-Caucasian), with a median aneurysm diameter of 5.9cm (IQR 5.4-6.8cm). Proximal clamp sites were: above one renal artery (31%), supra-renal (52%), and supra-celiac (17%). Rates of unadjusted outcomes were 20.5% for AKI, 4.1% for new-onset RRT, 4.9% for 30-day mortality, and 8.3% for one-year mortality. On adjusted analyses, independent of ischemia time, supra-renal clamping relative to clamping above a single renal artery had higher odds of postoperative AKI (aOR 1.50 [95%-CI 1.28-1.75]) but similar odds for new-onset RRT (aOR 1.27 [0.79-2.06]) and 30-day mortality (aOR 1.12 [0.79-1.58]) and hazards for one-year mortality (aHR 1.12 [0.86-1.45]). However, every ten minutes of prolonged intraoperative ischemia time was associated with an increase in odds or hazards ratio of postoperative AKI by +7% (IQR 3-11%), new-onset RRT by +11% (IQR 4-17%), 30-day mortality by +11% (IQR 6-17%), and one-year mortality by +7% (IQR 2-13%). Patients with greater than 40 minutes of ischemia time had notably higher rates of all four outcomes. DISCUSSION Supra-renal clamping relative to clamping above a single renal artery was associated with AKI but not new-onset RRT or 30-day mortality. However, intraoperative renal ischemia time was independently associated with all four postoperative outcomes. While further studies are warranted, our findings suggest that an expeditious proximal anastomosis creation is more important than trying to maintain clamp position below one renal artery, suggesting that suprarenal clamping may be the best strategy for open AAA repair when needed to efficiently perform the proximal anastomosis.

Abstract
OBJECTIVE Thromboelastography (TEG) is diagnostic modality that analyzes real-time blood coagulation parameters. Clinically, TEG primarily allows for directed blood component resuscitation among patients with acute blood loss and coagulopathy. The utilization of TEG has been widely adopted in among other surgical specialties; however, its use in vascular surgery is less prominent. We aimed to provide an up-to-date review of TEG utilization in vascular and endovascular surgery. METHODS Using PRISMA guidelines, a literature review with the Medical Subject Headings (MeSH) terms "TEG and arterial events", "TEG and vascular surgery", "TEG and vascular", "TEG and endovascular surgery", "TEG and endovascular", "TEG and peripheral artery disease", "TEG and prediction of arterial events", "TEG and prediction of complications ", "TEG and prediction of thrombosis", "TEG and prediction of amputation", and "TEG and amputation" was performed in Cochrane and PubMed databases to identify all peer-reviewed studies of TEG utilization in vascular surgery, written between 2000-2021 in the English language. The free text and MeSH subheadings search terms included diagnosis, complications, physiopathology, surgery, mortality, and therapy to further restrict the articles. Studies were excluded if they were not in humans or pertaining to vascular or endovascular surgery. Additionally, case reports and studies with limited information regarding TEG utilization were excluded. Each study was independently reviewed by two researchers to assess for eligibility. RESULTS Of the 262 studies identified through the MeSH strategy, 15 studies met inclusion criteria and were reviewed and summarized. Literature on TEG utilization in vascular surgery spanned cerebrovascular disease (n=3), peripheral arterial disease (n=3), arteriovenous malformations (n=1), venous thromboembolic events (n=7), and perioperative bleeding and transfusion (n=1). In cerebrovascular disease, TEG may predict the presence and stability of carotid plaques, analyze platelet function before carotid stenting, and compare efficacy of antiplatelet therapy after stent deployment. In peripheral arterial disease, TEG has been used to predict disease severity and analyze the impact of contrast on coagulation parameters. In venous disease, TEG may predict hypercoagulability and thromboembolic events among various patient populations. Finally, TEG can be utilized in the postoperative setting to predict hemorrhage and transfusion requirements. CONCLUSIONS This systematic review provides an up-to-date summarization of TEG utilization in multiple facets of vascular and endovascular surgery.

Abstract
BACKGROUND Superficial femoral artery (SFA) and profunda patency has been shown to affect aortofemoral bypass (AFB) limb patency. However, the effect of retrograde flow through the external iliac artery (EIA) is unknown and is the subject of this analysis. METHODS Institutional AFB data from 2000-2017 were gathered, excluding those where SFA/EIA patency could not be determined. The cohort was divided into limbs with and without EIA occlusion; primary outcome was limb-based primary patency. Kaplan-Meier estimated patency; cox proportional-hazards model evaluated EIA patency while controlling for other factors. RESULTS Over the study period, there were AFB 557 limbs in 281 patients. Of the 435 AFB limbs in 220 patients that met inclusion criteria and were included in the analysis, 162 had EIA occlusion and 273 had a patent EIA. Mean age was 69.6±9.0. EIA occlusions were more common in male patients (59.9% vs 44.6%; p=0.001), patients with CAD (43.8% vs 34.1%; p=0.042), COPD (34.6% vs 20.5%; p=0.001), and CHF (14.8% vs 5.9%; p=0.002). Limbs with EIA occlusions more often underwent end-to-side proximal anastomosis (40.7% vs 24.2%; p<0.001) and simultaneous infrainguinal bypass (7.4% vs 0.7%; p<0.001). Median clinical follow-up was 4.4 years (IQR: 1.6-8.4). Five-year primary patency was 83.1% (95% CI: 74.5%-90.0%) for EIA occlusion limbs and 85.9% (95% CI: 80.2%-90.0%) with patent EIA limbs (p=0.96). While controlling for other factors, EIA stenosis or occlusion did not affect primary patency. For patients with a proximal occlusion (occluded aorta, occluded common iliac, or end-to-end proximal anastomosis) and occluded SFA (N=73), EIA occlusion had a HR of 1.92 for loss of patency, but this was not statistically significant. CONCLUSION EIA patency did not influence primary patency in the overall cohort Further investigation on the topic in specific patient subgroups is warranted to determine the effect of EIA patency.

Abstract
BACKGROUND Unlike periprocedural Type 1A endoleaks, late appearing proximal endoleaks have been poorly described. METHODS We studied all elective EVAR from 2010 -2018 in a single institution. Late endoleaks were defined as those appearing after 1 year. We used Cox regression to study factors associated with late Type 1A endoleaks and survival. RESULTS Of 477 EVAR during the study period, 411 (86%) had follow-up imaging, revealing 24 Type 1A endoleaks; 4 early and 20 late. Freedom from Type 1A endoleaks was 99%, 92-81% at 1, 5 and 8 years with a median time to occurrence of 2.5 years (.01-8.2 years). On completion angiogram, only 10% of patients with a late Type 1A had a proximal endoleak, and 60% had no endoleak. Only 21% of late Type 1As were diagnosed on routine 1-year CT angiogram, but 79% had stable or expanding sacs. Two thirds (65%) of the patients eventually diagnosed with late Type 1A endoleaks had previously been treated for other endoleaks, mostly Type 2 (10/13). Age (HR 1.07/year [1.02-1.12], P = 0.01), neck diameter >28mm (HR 3.5 [1.2-10.3], P = 0.02), neck length <20mm (HR 3.0 [1.1-8.6], P = 0.04), and neck angle>60 degrees (HR 3.4 [1.5-7.9], P = 0.004) were associated with higher rates of Type 1A endoleak, but not female sex, endograft, or the use of suprarenal fixation. 2 patients had proximal degeneration and 5 experienced graft migration. There were 2 ruptures (10%), and 13 patients underwent repair with 5 open conversions. Median survival after late Type 1A repair was 6.6 years (0-8.4 years). CONCLUSION Late appearing Type 1A endoleaks have a high rate of rupture and present significant diagnostic and management challenges. Careful surveillance is needed in patients with hostile neck anatomy and those who undergo intervention for other endoleaks. Adverse neck anatomy may be better suited for open repair or fenestrated/branched devices rather than conventional EVAR.

Abstract
BACKGROUND The Society for Vascular Surgery (SVS) recently published clinical practice guidelines on the management of visceral aneurysms. However, studies investigating the perioperative outcomes of open repair of visceral aneurysms have been limited to single-center experiences with variable results that span multiple decades. In the present study, we sought to detail the morbidity and mortality associated with open repair of visceral aneurysms using a national database in the contemporary era. METHODS National Surgical Quality Improvement Program data from 2013 to 2019 were queried for patients who had undergone open repair of visceral aneurysms, which had been classified as mesenteric, renal, or splenic using Current Procedural Terminology and International Classification of Diseases codes. The primary endpoint was the composite of major complications (cardiovascular, pulmonary, progressive renal failure, deep wound infection, return to operating room, sepsis) and 30-day mortality. Logistic regression was used to identify the predictors of the primary endpoint for nonruptured aneurysm cases. RESULTS Of the 304 aneurysms, 263 were nonruptured (137 mesenteric, 66 renal, 60 splenic) and 41 were ruptured (24 mesenteric, 1 renal, 16 splenic) and had undergone open repair. For those with nonruptured aneurysms, their mean age was 59.4 ± 14.7 years and 48.3% were women. For those with nonruptured aneurysms, the 30-day mortality was 1.9% and the major complication rate was 12.9%. A return to the operating room (5.3%) and prolonged ventilator support (3.8%) were especially common. As expected, rupture was associated with significantly greater mortality (22.0%; P < .001) and major complications (34.1%; P = .001). The use of postoperative transfusion was common in the elective group but was significantly greater in the ruptured group (24.3% vs 80.5%; P < .001). The predictors of the primary outcome for nonruptured aneurysms included male sex (odds ratio [OR], 2.93; 95% confidence interval [CI], 1.28-6.7; P = .011), anticoagulation (not discontinued before surgery) or bleeding disorder (OR, 4.52; 95% CI, 1.37-14.7; P = .012), and albumin <3.0 g/dL (OR, 4.66; 95% CI, 1.17-18.6; P = .029). Neither age nor aneurysm location were significant risk factors. CONCLUSIONS Open repair of visceral aneurysms was associated with acceptable morbidity and mortality, although these risks are significantly greater once ruptured. Male sex, bleeding risk, and low albumin were all risk factors for adverse events and should be considered for operative planning and postoperative care.

Abstract
OBJECTIVES Kommerell diverticulum (KD) is a rare congenital vascular anomaly often associated with an aberrant subclavian artery (ASCA). Definitive indications for intervention remain unclear. We present open and endovascular (EV) operative outcomes in a large contemporary series and propose a management algorithm. METHODS Between 2004 and 2020, 224 patients presented with ASCA and associated KD to our institution. Of the 43 (19.2%) patients who underwent operative repair, 31 (72.1%) had open surgical (OS) repair via thoracotomy and 12 (27.9%) had EV repair. Univariable and bivariable statistical analyses were conducted stratified by approach. The median follow-up time was 5.4 years (IQR, 2.9-9.7). RESULTS Patients in EV group were older (68 years vs 47 years, P < 0.001) and had larger aneurysms (base diameter 3.2 cm vs 21.5 cm, P = 0.007). All patients with dysphagia lusoria were treated with open surgery (n = 20). Asymptomatic patients with incidentally detected KD (50% vs 16.1%), those with chest or back pain (50% vs 19.4%) and patients who presented with an aortic emergency (25% vs 6.5%) were more likely to be treated endovascularly (P = 0.001). Carotid-to-subclavian bypass was used in 38 (88.4%) patients. There were no operative mortalities. In-hospital mortality was similar between groups (3.2% vs 16.7%, P = 0.121). Mid-term mortality was higher in the EV group [4 (33.8%) vs 0, P < 0.001]. There were 2 (15.4%) postoperative strokes in the EV group. There were no statistically significant differences in other postoperative complications or hospital length of stay between groups. CONCLUSIONS KD can be managed using open or EV approaches with low morbidity and mortality. Treatment strategy should depend on clinical presentation and patient factors.

Abstract
Background: Literature detailing the natural history of asymptomatic penetrating aortic ulcers (PAU) is sparse and lacks long-term follow-up. This study sought to determine the rate of asymptomatic PAU growth over time and adverse events from asymptomatic PAU. Methods: A cohort of patients with asymptomatic PAU from 2005-2020 was followed. One ulcer was followed per patient. Primary endpoints were change in size over time and the composite of symptoms, radiographic progression, rupture, and intervention; cumulative incidence function estimated the incidence of the composite outcome. Ulcer size and rate of change were modeled using a linear mixed effects model. Patient and anatomic factors were evaluated as potential predictors of the outcomes. Results: There were 273 patients identified. Mean age was 75.5±9.6 years; 66.4% were male. The majority of ulcers were in the descending thoracic aorta (53.9%), followed by abdominal aorta (41.4%), and aortic arch (4.8%). Fusiform aneurysmal disease was present in 21.6% of patients at a separate location; 2.6% had an associated intramural hematoma; 23.6% had at least one other PAU. Symptoms developed in one patient who ruptured; 8 patients (2.9%) underwent an intervention for PAU (one for rupture, 2 for radiographic progression, 5 for size/growth) at a median of 3.1 years (IQR:1.0-6.5) after diagnosis. Five and 10-year cumulative incidence of the primary outcome, adjusted for competing risk of death, was 3.6% (95% CI: 1.6-6.9%) and 6.5% (95% CI: 3.1-11.4%), respectively. For 191 patients with multiple CT scans (760 total CT's) with median radiographic follow-up of 3.50 years (IQR:1.20-6.63 years), mean initial ulcer width, ulcer depth, and total diameter in millimeters (mm) was 13.6, 8.5, and 31.4, respectively. Small, but statistically significant change over time was observed for ulcer width (0.23 mm/year) and total diameter (0.24 mm/year); ulcer depth did not significantly change over time. Hypertension, hyperlipidemia, diabetes, initial ulcer width>20 mm, thrombosed PAU, and associated saccular aneurysm were associated with larger changes in ulcer size over time, however the magnitude of difference was small, ranging from 0.4-1.9 mm/year. Conclusions: Asymptomatic PAU displayed minimal growth and infrequent complications including rupture. Asymptomatic PAU may be conservatively managed with serial imaging and risk-factor modification.

Abstract
OBJECTIVES In the ever-advancing era of endovascular thoracoabdominal aneurysm (TAAA) repair, understanding long-term patency of renovisceral reconstructions after open TAAA repair provides important benchmarks. METHODS Institutional open TAAA repair patient data were queried. Patients dying during index admission or with incomplete operative detail were excluded. Visceral and renal reconstructions were categorized as bypass, incorporation into a proximal or distal beveled aortic anastomosis, inclusion button, Carrel patch, or hybrid stent along with endarterectomy/stent adjuncts. Axial imaging or angiography determined long-term patency. Vessel event was defined as new occlusion or reintervention after repair. Overall time-to-event analysis was performed as well as separate analyses for each vessel (Celiac, SMA, right renal, left renal) by reconstruction type utilizing Kaplan-Meier methods. Log-rank testing was employed to compare reconstructive strategies. RESULTS Over 28-years, 604 repairs [Type I 106(18%), Type II 73(12%), Type III 195(32%), Type IV 230(38%)] were identified. Follow-up (median 500 days) was available in 410/570(72%) Celiac, 406/573(71%) SMA, 379/532(71.2%) right renal, and 370/515(72%) left renal reconstructions. There were five celiac, one SMA, eight right renal, and ten left renal events. No type of reconstruction or adjunct was significantly associated with event. Overall 5-year patency of all renal/visceral reconstructions was 94% (95%CI [90%-96%]). Estimated 5-year patency of the Celiac, SMA, left renal, and right renal were similar, and were 99%, 100%, 97%, and 96%, respectively (p = .09). CONCLUSIONS Visceral and renal long-term patency after open TAAA repair is excellent regardless of reconstructive technique. No differences are appreciated even when target vessel disease is addressed at the time of reconstruction. These findings continue to substantiate the effective long-term durability of open TAAA repair and are particularly germane to the ongoing evolution of endovascular strategies.

Abstract
OBJECTIVE/BACKGROUND Endovascular aneurysm repair (EVAR) is associated with worse outcomes in patients whose anatomy does not meet the device instructions for use (IFU). However, whether open surgical repair (OSR) and commercially available fenestrated EVAR (Zenith Fenestrated [ZFEN]) represent better options for these patients is unknown. METHODS We identified all patients without prior aortic surgery undergoing elective repair of abdominal aortic aneurysms with neck length ≥4 mm at a single institution with EVAR, OSR, and ZFEN. We applied device-specific aneurysm neck-related IFU to EVAR patients, and a generic EVAR IFU to ZFEN and OSR patients. Long-term outcomes were studied using propensity scores with inverse probability weighting. We compared outcomes in patients undergoing EVAR by adherence to IFU and outcomes by repair types in the subset of patients not meeting IFU. RESULTS Of 652 patients (474 EVAR, 34 ZFEN, 143 OSR), 211 had measurements outside of standard EVAR IFU (109 EVAR [23%], 27 ZFEN [80%], and 74 OSR [52%]). Perioperative mortality was 0.5% overall. For EVAR, treatment outside the IFU was associated with significantly higher adjusted rates of long-term type IA endoleak (22% at 5 years compared to 2% within IFU, hazard ratio [HR]: 5.8 [3.1-10.9], P < .001), and lower survival (5- and 10-year survival: 56% and 34% vs 81% and 53%, HR: 2.3 [1.2-4.3], P = .01). There was no difference in reinterventions or open conversion. In patients not meeting IFU, ZFEN was associated with higher adjusted rates of reinterventions (EVAR as referent: HR: 2.6 [1.5-4.4, P < .001), whereas OSR and EVAR patients experienced similar reintervention rates (HR: 0.7 [0.4-1.1], P = .13). Patients outside the IFU experienced lower mortality with OSR compared with either EVAR (HR: 0.4 [0.2-0.9], P = .005) or ZFEN (HR: 0.3 [0.1-0.7], P = .002). When restricted to patients outside the IFU deemed fit for open repair, OSR patients remained associated with lower adjusted mortality compared with ZFEN (HR: 0.2 [0.1-0.5], P < .001), but statistical significance was lost in the comparison to EVAR (HR: 0.6 [0.3-1.1], P = .1). CONCLUSIONS Treatment outside device-specific IFU is associated with adverse long-term outcomes. Open surgical repair is associated with higher long-term survival in patients who fall outside of the EVAR IFU and should be favored over EVAR or ZFEN in suitable patients. A three-vessel-based fenestrated strategy may not be a durable solution for difficult aortic necks, but more data are needed to evaluate the performance of newer, four-vessel devices.

Abstract
BACKGROUND A recent review of Vascular Study Group of New England data suggested that simultaneous endovascular treatment of tandem carotid lesions (TCAL: common carotid artery + internal carotid artery) is associated with a fourfold increase in perioperative neurologic events and death. However, given the small cohort, the effect of symptomatic status could not be evaluated. This study sought to determine the risk of simultaneous TCAL stenting in cohorts stratified by symptom status. METHODS Vascular Quality Initiative data (2005-2020) were queried for carotid stenting procedures (CAS). Emergent and bilateral procedures, patients with prior ipsilateral CAS, internal carotid artery lesions with stenosis <50%, and hybrid transcarotid procedures were excluded. The cohort was stratified by symptomatic status. The primary outcome was the composite of perioperative stroke and death. Predictors of stroke/death were determined with multivariable logistic regression for symptomatic and asymptomatic patients with TCAL forced into the models. RESULTS There were 18,886 carotid arteries stented (18,441 patients): 18,077 (96%) with isolated carotid artery lesions and 809 (4%) with TCAL. Mean age was 70.0 ± 9.7. Symptomatic lesions were present in 58.9% of cases (isolated carotid artery lesions: 59.1% vs TCAL: 52.5%; P < .001). More TCAL arteries had a prior carotid endarterectomy (38.3% vs 23.8%; P < .001). TCAL had a higher perioperative stroke/death (3.4% vs 1.8%; P = .026) for asymptomatic lesions, but not symptomatic lesions (4.5% vs 3.7%; P = .41). TCAL were independently associated with stroke/death in asymptomatic patients (odds ratio, 1.85; 95% confidence interval, 1.03-3.33; P = .039) but not symptomatic patients (odds ratio, 1.22; 95% confidence interval, 0.76-1.97; P = .42). CONCLUSIONS The addition of endovascular treatment of common carotid artery lesions with CAS is associated with almost double the risk of perioperative stroke/death in asymptomatic patients and should be avoided if possible. Treatment of TCAL is not associated with an increased risk of stroke/death for symptomatic lesions.

Abstract
BACKGROUND Anterior lumbar spine surgery (ALSS) requires mobilization of the great vessels, resulting in a high risk of iatrogenic vascular injury (VI). It remains unclear whether VI is associated with increased risk of postoperative complications and other related adverse outcomes. PURPOSE The purpose of this study was to (1) assess the incidence of postoperative complications attributable to VI during ALSS, and (2) outcomes secondary to VI such as procedural blood loss, transfusion of blood products, length of stay (LOS), and in hospital mortality. STUDY DESIGN Retrospective propensity-score matched, case-control study at 2 academic and 3 community medical centers, PATIENT SAMPLE: Patients 18 years of age or older, undergoing ALSS between January 1st, 2000 and July 31st, 2019 were included in this analysis. OUTCOME MEASURES The primary outcome was the incidence of postoperative complications attributable to VI, such as venous thromboembolism, compartment syndrome, transfusion reaction, limb ischemia, and reoperations. The secondary outcomes included estimated operative blood loss (milliliter), transfused blood products, LOS (days), and in-hospital mortality. METHODS In total, 1,035 patients were identified, of which 75 (7.2%) had a VI. For comparative analyses, the 75 VI patients were paired with 75 comparable non-VI patients by propensity-score matching. The adequacy of the matching was assessed by testing the standardized mean differences (SMD) between VI and non-VI group (>0.25 SMD). RESULTS Two patients (2.7%) had VI-related postoperative complications in the studied period, which consisted of two deep venous thromboembolisms (DVTs) occurring on day 3 and 7 postoperatively. Both DVTs were located in the distal left common iliac vein (CIV). The VI these patients suffered were to the distal inferior vena cava and the left CIV, respectively. Both patients did not develop additional complications in consequence of their DVTs, however, did require systemic anticoagulation and placement of an inferior vena cava filter. There was no statistical difference with the non-VI group where no instances (0%) of postoperative complications were reported (p=.157). No differences were found in LOS or in hospital mortality between the two groups (p=.157 and p=.999, respectively). Intraoperative blood loss and blood transfusion were both found to be higher in the VI group in comparison to the non-VI group (650 mL, interquartile range [IQR] 300-1400 vs. 150 mL, IQR 50-425, p≤.001; 0 units, IQR 0-3 vs. 0 units, IQR 0-1, p=.012, respectively). CONCLUSION This study found a low number of serious postoperative complications related to VI in ALSS. In addition, these complications were not significantly different between the VI and matched non-VI ALSS cohort. Although not significant, the found DVT incidence of 2.7% after VI in ALSS warrants vigilance and preventive measures during the postoperative course of these patients.

Abstract
OBJECTIVE Splenectomy is often performed during open thoracoabdominal aortic aneurysm (TAAA) repair, because capsular tears are common and can be associated with significant bleeding. It is unknown whether splenectomy affects the short- or long-term outcomes after TAAA repair. METHODS All open type I to IV TAAA repairs performed from 1987 to June 2015 were evaluated using a single institutional database. The primary endpoints were in-hospital death, major adverse events (MAE) and long-term survival. The secondary endpoint was hospital length of stay (LOS). All repairs performed for aneurysm rupture were excluded. Univariate analysis was conducted using the Fisher's exact test for categorical variables and the Wilcoxon rank sum test for continuous variables. Logistic and linear multivariable regression were used for the in-hospital endpoints, and survival analyses were performed using Cox proportional hazards modeling and Kaplan-Meier techniques. RESULTS A total of 649 patients met the study inclusion criteria. Of the 649 patients, 150 (23%) underwent concurrent splenectomy (CS) and six required emergency splenectomy secondary to bleeding postoperatively, leading to 156 cases of total in-hospital splenectomy. The perioperative mortality rate was 5.2% in the CS group and 5.2% in the non-CS group (P = 1.0). MAE were experienced by 48% of the CS patients compared with 34% of the non-CS patients (P = .003). Multivariable analysis revealed splenectomy was not independently predictive of perioperative death (adjusted odds ratio, 0.95; 95% confidence interval [CI], 0.41-2.23; P = .9). However, splenectomy was independently associated with any MAE (adjusted odds ratio, 1.78; 95% CI, 1.19-2.65; P = .005). Splenectomy was also associated with a longer length of stay (+5.39 days; 95% CI, 1.86-8.92; P = .003). No survival difference was found between the cohorts in the total splenectomy cohort in the unadjusted (log-rank P = 1.0) or adjusted (splenectomy adjusted hazard ratio, 1.02; 95% confidence interval, 0.78-1.35; P = .9). CONCLUSIONS CS during open TAAA repair did not lead to increased perioperative mortality but did lead to significantly increased perioperative morbidity and longer hospital lengths of stay. We found no difference in long-term survival outcomes when CS was performed. Splenectomy during TAAA repair did not affect long-term survival.

Abstract
BACKGROUND Addition of ipsilateral proximal endovascular intervention (PEI, common carotid/innominate) increases the risk of perioperative stroke/death for both carotid endarterectomy (CEA) and carotid stenting (CAS). However, these approaches have not been directly compared and is the subject of this study. METHODS VQI (2005-2020) was queried for CEA and CAS with PEI, excluding emergent, bilateral, and repeat procedures, patients with prior ipsilateral CAS, ICA lesions with stenosis<50%, and transcarotid ICA stents. Primary outcome were the composite of perioperative stroke/death and long-term stroke/reintervention/death. Operative approach was evaluated with logistic regression, adjusted propensity scores, symptomatic status, and stenosis>70%. Long-term outcomes were compared with Kaplan-Meier Analysis. RESULTS There were 1,433 patients (795 endovascular;638 hybrid); mean age 69.8±9.4 years. Patients undergoing hybrid procedures were more likely to be female (49.4% vs. 37.5%; P < 0.001), less likely to have diabetes (29.5% vs. 38.2%; P P< 0.001), less likely to have a prior ipsilateral CEA (3.8% vs. 32.2%; P< 0.001), less likely to be symptomatic (34.6% vs. 52.8%; P < 0.001), and less likely to have >70% stenosis (77.3% vs. 95.6%%; P < 0.001). Perioperative stroke/death was 3.6% for hybrid and 3.9% for endovascular approaches (P = 0.77). In the multivariable model, hybrid operative approach (compared to the total endovascular approach) was not significantly associated with stroke/death (OR 1.29; 95%CI: 0.55-3.07; P = 0.56). For the 981 patients with long-term follow-up (556 endovascular; 425 hybrid), 1-year freedom from stroke/reintervention/death was 94.0% (95%CI: 90.9%-96.0%) for hybrid approach vs. 92.3% (95%CI: 89.5%-94.4%) for endovascular approach (P = 0.27). CONCLUSION Although simultaneous repair of tandem carotid lesions portends worse outcomes when compared to CEA or CAS alone, there was no difference in short or long-term stroke and death rates with a hybrid or totally endovascular approach. Therefore, it is reasonable to use either approach in the select patients who require simultaneous repair of both lesions.

Abstract
OBJECTIVE In the last two decades, vascular surgery training evolved from exclusively learning open skills to learning endovascular skills in addition to a functional reduction in training duration with 0+5 residency programs. The implications for this on trainee evolution to independence are unknown. We aimed to assess self-perceived comfort performing open and endovascular procedures and to identify predictors of high comfort among senior vascular surgery trainees and recent graduates. METHODS Junior and senior 0+5 vascular surgery residents, traditional fellows, and attendings in their first 4 years of practice were asked to complete a survey assessing the number of vascular procedures performed to date, comfort performing these procedures on a Likert scale, and validated scales of self-efficacy and grit. Groups were then matched by training level and age. Logistic regression identified independent predictors of the top quartile of self-perceived comfort performing procedures. RESULTS Surveys were completed by 92 trainees and 71 attending surgeons in their first 4 years of practice. After matching, completing ≥7 open juxtarenal aortic repairs (OR = 4.73, 95% CI = 1.59-14.07) and a higher self-efficacy score (OR = 3.24, 95% CI = 1.20-8.76), were independent predictors of top quartile comfort performing open vascular procedures. 0+5 residency training inversely correlated with top quartile comfort performing open vascular operations (OR = 0.12, 95% CI = 0.03-0.47). Completing ≥7 complex EVARs (OR = 3.94, 95% CI = 1.61-9.59) and a higher self-efficacy personality score (OR = 2.76, 95% CI = 1.09-7.02) were predictors of top quartile comfort performing endovascular procedures. CONCLUSION In this nationally representative survey, both trainees and junior attendings completed a paucity of complex open vascular cases, which corresponded to reduced comfort performing these procedures. Furthermore, 0+5 residency training was associated with lower self-perceived comfort performing open vascular surgery, a trend that persisted through the first years of practice. Endovascular comfort did not show a similar correlation.

Abstract
BACKGROUND A nationwide variation in mortality stratified by hospital volume exists after open repair of complex abdominal aortic aneurysms (AAAs). In the present study, we assessed whether the rates of postoperative complications or failure-to-rescue (defined as death after a major postoperative complication) would better explain the lower mortality rates among higher volume hospitals. METHODS Using the 2004 to 2018 Vascular Quality Initiative database, we identified all patients who had undergone open repair of elective or symptomatic AAAs, in which the proximal clamp sites were at least above one renal artery. We divided the patients into hospital quintiles according to the annual hospital volume and compared the risk-adjusted outcomes. Multivariable logistic regression, adjusted for patient characteristics, operative factors, and hospital volume, was used to evaluate three outcomes: 30-day mortality, overall complications, and failure-to-rescue. RESULTS We identified 3566 patients who had undergone open repair of elective or symptomatic complex AAAs (median age, 71 years; 29% women; 4.1% black; 48% Medicare insurance). The unadjusted rates of 30-day postoperative mortality, overall complications, and failure-to-rescue were 5.0%, 44%, and 10%, respectively. Common complications included renal dysfunction (25%), cardiac dysrhythmia (14%), and pneumonia (14%), with the specific failure-to-rescue rate ranging from 12% to 22%. On adjusted analysis, the risk-adjusted mortality rate was 2.5 times greater for the lower volume hospitals relative to the higher volume hospitals (7.4% vs 3.0%; P < .01). Although the risk-adjusted complication rates were similar between these hospital groups (30% vs 27%; P = .06), the failure-to-rescue rate was 2.3 times greater for the lower volume hospitals relative to the higher volume hospitals (6.3% vs 2.7%; P = .02). CONCLUSIONS Higher volume hospitals had lower mortality rates after open repair of complex AAAs because they were better at the "rescue" of patients after the occurrence of postoperative complications. Both an understanding of the clinical mechanisms underlying this association and the regionalization of open repair might improve patient outcomes.

Abstract
Right ventricular (RV) function is a critical determinant of survival in patients with pulmonary arterial hypertension (PAH). While miR-21 is known to associate with vascular remodeling in small animal models of PAH, its role in RV remodeling in large animal models has not been characterized. Herein, we investigated the role of miR-21 in RV dysfunction using a sheep model of PAH secondary to pulmonary arterial constriction (PAC). RV structural and functional remodeling were examined using ultrasound imaging. Our results showed that post PAC, RV strain significantly decreased at the basal region compared with t the control. Moreover, such dysfunction was accompanied by increases in miR-21 levels. To determine the role of miR-21 in RV remodeling secondary to PAC, we investigated the molecular alteration secondary to phenylephrine induced hypertrophy and miR21 overexpression in vitro using neonatal rat ventricular myocytes (NRVMs). We found that overexpression of miR-21 in the setting of hypertrophic stimulation augmented only the expression of proteins critical for mitosis but not cytokinesis. Strikingly, this molecular alteration was associated with an eccentric cellular hypertrophic phenotype similar to what we observed in vivo PAC animal model in sheep. Importantly, this hypertrophic change was diminished upon suppressing miR-21 in NRVMs. Collectively, our in vitro and in vivo data demonstrate that miR-21 is a critical contributor in the development of RV dysfunction and could represent a novel therapeutic target for PAH associated RV dysfunction.

Abstract
BACKGROUND Tandem carotid artery lesions that involve simultaneous internal carotid artery (ICA) and common carotid artery (CCA) stenoses present a complex clinical problem. Some studies have shown that the addition of a retrograde proximal intervention to treat a CCA lesion during a carotid endarterectomy (CEA) increases the risk of stroke and death. However, the stroke and death risks associated with a totally endovascular approach to tandem lesions is unknown and is the subject of this study. METHODS Vascular Study Group of New England data for the years 2005 to 2020 were queried for carotid artery stenting (CAS) procedures. Emergent and bilateral procedures, procedures for indications other than atherosclerosis, patients with prior ipsilateral CAS, ICA lesions with stenosis of less than 50%, and transcarotid procedures were excluded. The cohort was divided into tandem and isolated lesion groups. The primary outcome was the composite of stroke and death. Predictors of stroke or death were determined with multivariable logistic regression. RESULTS There were 2016 carotid arteries stented in 1950 patients-1881 (96%) with isolated lesions and 135 (4%) with tandem lesions. The mean patient age was 69.6 ± 9.0 years. Tandem lesions were more likely to be present in women (50.4% vs 33.0%; P < .001) and in patients with a prior carotid endarterectomy (45.9% vs 35.4%; P = .014). Other covariates were similar between the groups. Symptomatic lesions accounted for 42.3% of cases (isolated, 42.2% vs tandem, 43.0%; P = .86). Arteries in the tandem group more often required multiple stents to treat the ICA lesion (9.6% vs 5.2%; P = .027). ICA neuroprotection had similar outcomes in both groups (tandem: success 94.1%, failure 3.7%; isolated: success 96.3%, failure 1.8%; P = .29). The tandem group experienced a higher 30-day mortality (2.2% vs 0.6%; P = .039), more perioperative neurologic events (stroke or transient ischemic attack) (8.1% vs 2.0%; P < .001), and a higher incidence of stroke or death (5.9% vs 1.9%; P = .002). Predictors of the primary outcome in the multivariable model included treatment of tandem lesions (odds ratio [OR], 3.10; 95% confidence interval [CI], 1.39-6.89; P = .006), symptomatic lesions (OR, 2.24; 95% CI, 1.21-4.17; P = .010), chronic obstructive pulmonary disease (OR, 2.14; 95% CI, 1.17-3.92; P = .014), general anesthesia (OR, 3.34; 95% CI, 1.35-8.26; P = .009), and advancing age (OR, 1.05 per year; 95% CI, 1.01-1.09; P = .006). CONCLUSIONS The addition of endovascular treatment of tandem CCA lesions with CAS is associated with a three-fold increase in perioperative stroke and death and should be avoided if possible.

Abstract
OBJECTIVE The objective of this study was to assess the perioperative and long-term outcomes of carotid body tumor (CBT) resection with a multispecialty (head and neck surgery/vascular surgery) approach. METHODS Our institutional data registry was queried for Current Procedural Terminology codes (60600, 60605) pertaining to CBT excision. These patient records and operative reports were individually reviewed to determine laterality, preoperative tumor embolization, operative time, estimated blood loss, need for intraoperative transfusion, intraoperative electroencephalogram changes, intraoperative division of the external carotid artery, carotid artery repair, resection of the carotid bifurcation, tumor volume, final pathology, cranial nerve injury, stroke, death, and clinical or radiographic evidence of recurrence. RESULTS From 1996 to 2018, 74 CBT resections were identified in 68 patients (41 [60%] females; mean age, 50.83 years). The mean tumor volume was 9.92 ± 14.26 cm3 (range, 0.0250-71.0627 cm3). Embolization was performed by a neurointerventional specialist in 27 CBT resections (36%) based on size (embolization 14.27 ± 16.84 cm3 vs 7.17 ± 11.86 cm3; P = .063) and superior extension. This practice resulted in one asymptomatic vertebral dissection, which postponed the surgery. There was a trend toward greater blood loss in the embolization group (embolization 437 ± 545 mL vs 262 ± 222 mL; P = .17); however, no transfusions were required in any patient. The mean operative time was also significantly longer in the embolization group (198.33 ± 61.13 minutes vs 161.5 ± 55.56 minutes; P = .03). Three resections had reversible intraoperative electroencephalogram changes, one of which occurred during carotid clamping. These changes resolved with shunting. Eight external carotid resections (11%) and 6 carotid reconstructions (8.1%; two primary, two patch, and two primary anastomosis) were required. Malignancy was identified in four tumors (5.4%), accounting for four of the six carotid reconstructions. There were no postoperative cranial nerve injuries, no strokes, no reexplorations, and no deaths. One patient developed transient dysphagia from pharyngeal tumor infiltration. Long-term follow-up (mean, 43 ± 54 months), available in 61 of the 68 patients (89.7%), revealed three (4.4%) recurrences. CONCLUSIONS This large, single-institution series demonstrates that a multispecialty team combining two surgical skill sets for the treatment of this rare, challenging condition yields unparalleled low complication rates with short operative times. This approach, including long-term surveillance for recurrent disease, should be considered to optimize outcomes of CBT resection.

Abstract
OBJECTIVE Although the transabdominal approach (TAA) and lateral approach (LA) to open abdominal aortic aneurysm repair (OAR) are both acceptable and widely used, a paucity of data evaluating subsequent postoperative laparotomy-associated complications (LCs) is available. The aim of the present study was to establish the incidence of LCs after OAR and determine which approach was associated with an increase in long-term LCs. METHODS An institutional database for OAR (2010-2019) was queried, excluding urgent and emergent cases. The primary endpoint was long-term LCs, defined as any complication related to entry into the abdomen. The LA included retroperitoneal and thoracoabdominal approaches and the TAA included all patients with midline incisions. A Kaplan-Meier analysis was used to estimate the freedom from LCs, and the Fine-Gray method was used to determine the predictors of LCs, with death as a competing risk. RESULTS A total of 241 patients (mean age, 70.0 ± 9.1 years; 71.7% men) had undergone OAR, 91 via a TAA and 150 via a LA. The patients in the TAA group were significantly younger (age, 66.7 ± 8.9 vs 72.1 ± 8.7 years; P < .001), more likely to be male (83.5% vs 64.7%; P = .002), and more likely to have a history of small bowel obstruction (SBO; 3.3% vs 0%; P = .025). Patients in the LA group were more likely to have required a supraceliac clamp (20.7% vs 1.1%; P < .001). No difference was found in the incidence of perioperative complications or long-term mortality. The most common LCs were hernia (TAA, 26.4%; LA, 11.3%; P = .003), SBO (TAA, 8.8%, LA, 1.3%; P = .005), and other (TAA, 13.2%; LA, 2.0%; P = .001), which included evisceration, bowel ischemia, splenic injuries requiring reintervention, enterocutaneous fistula, internal hernia, and retrograde ejaculation. Operative LCs were more common in the TAA group (17.6% vs 2.7%; P < .001). The unadjusted 1-, 3-, and 5-year freedom from LCs was 77.7% (95% confidence interval [CI], 66.0%-85.8%), 60.5% (95% CI, 46.5%-71.9%), and 54.0% (95% CI, 38.8%-67.0%) for TAA and 94.8% (95% CI, 88.8%-97.7%), 82.2% (95% CI, 72.2%-88.9%), and 79.1% (95% CI, 68.4%-86.5%) for LA, respectively (log-rank P < .001). The predictors for LCs were a history of SBO (P = .001), increasing body mass index (P = .005), and the use of the TAA (P < .001). CONCLUSIONS Use of the TAA was an independent predictor of long-term LCs after OAR, along with an increasing body mass index and a history of SBO. In patients with amenable anatomy, the LA is favorable for preventing long-term LCs, especially in high-risk patients.

Abstract
OBJECTIVE Although percutaneous brachial access has been used more often for peripheral vascular interventions (PVIs), previous studies have suggested that open brachial artery exposure for access is associated with fewer complications than percutaneous access. The present study sought to determine the incidence of complications for each access method and identify the predictors of access site complications after brachial access. METHODS The Vascular Quality Initiative national database was queried for all patients who had undergone PVI with brachial artery access from 2016 to 2019. Procedures with simultaneous thrombolysis or open procedures were excluded. The primary outcome was any perioperative brachial artery access complications. Multivariable logistic regression was used to identify any associated predictors. RESULTS A total of 1400 procedures had been performed for 1242 patients; 189 procedures (13.5%) had used an open exposure. The mean patient age was 67.3 ± 9.5 years, and 55.7% of the procedures were on men. No significant demographic differences were found between the open and percutaneous groups. Open exposure procedures were more likely to have used sheaths >5F (79.4% vs 59.0%; P < .001) and treated more arteries (2.0 ± 1.8 vs 1.7 ± 0.9; P < .001) but less likely to have used multiple access sites (8.5% vs 20.1%; P < .001). Access complications occurred in 7.5% of the percutaneous procedures and 1.6% of the open exposures (P = .003). Percutaneous access was independently associated with the occurrence of brachial access complications (odds ratio [OR], 5.92; 95% confidence interval [CI], 1.76-19.9; P = .004). Other associated factors included female sex (OR, 2.23; 95% CI, 1.44-3.44; P < .001), congestive heart failure (OR, 2.02; 95% CI, 1.26-3.24; P = .003), and increasing sheath size (OR, 1.36 per each 1F increase in size; 95% CI, 1.07-1.72; P = .011); diabetes was protective (OR, 0.53; 95% CI, 0.33-0.83; P = .006). CONCLUSIONS Open exposure might be advantageous compared with percutaneous access for preventing complications after brachial access. However, the difference in complications was driven by hematomas that were managed nonoperatively. Operative complications were more common in the percutaneous group, although this did not reach statistical significance. Percutaneous access should be used cautiously in women, patients with a history of congestive heart failure, those without diabetes, and interventions in which larger sheaths are required.

BACKGROUND Although outcomes after infrarenal abdominal aortic aneurysm surgery are worse in females, sex-specific differences in outcomes after open thoracoabdominal aortic aneurysm (TAAA) repair are less clear. The goal of this study was to identify sex-based disparities in short- and long-term outcomes after open type I-III TAAA surgery. METHODS All open type I-III TAAA repairs performed from 1987 to 2015 were evaluated using an institutional database. Charts were retrospectively evaluated for perioperative outcomes: major adverse events (MAEs), in-hospital death, and long-term survival. Univariate analysis was performed using the Fisher's exact test for categorical variables and the Wilcoxon rank-sum test for continuous variables. Logistic regression was used for in-hospital end points; survival analyses were performed with Cox proportional hazards modeling and Kaplan-Meier techniques. Sensitivity analyses were performed for relevant multivariable models, one with ruptures removed and another evaluating only repairs performed before 2006 to account for any selection bias due to wider use of complex endovascular technology. RESULTS Five-hundred sixteen patients underwent open type I-III TAAA repair during the study period. Females accounted for 54.3% (n = 280) of the cohort. Women were older, less likely to have a chronic dissection etiology, more likely to present with a symptomatic/ruptured lesion, and had a lower admission creatinine than men. Perioperative death occurred in 23 men (9.8%) and 19 women (6.8%) (P = 0.26); 133 women (47.3%) and 116 men (49.2%) suffered an MAE (P = 0.72). Multivariable analyses revealed no sex-based difference in perioperative death (Female sex adjusted odds ratio (AOR): 0.72, 95% confidence interval (CI): 0.4-1.4, P = 0.34) or MAE (AOR: 1.0 CI: 0.7-1.5, P = 0.82). Unadjusted survival at five years was 50% for women and 67% for men (log-rank P < 0.001). Female sex was an independent predictor of decreased survival (hazard ratio (HR): 1.5 95% CI: 1.2-1.9, P = 0.001) when adjusted for age, aneurysm extent, creatinine, chronic obstructive pulmonary disease, and ruptures. After removing all ruptures, female sex remained nonpredictive of perioperative death (AOR: 1.1, 95% CI 0.5-2.5, P = 0.75) or MAE (AOR: 1.2, CI: 0.8-1.9, P = 0.31) and predictive of decreased long-term survival (HR: 1.5, 95% CI: 1.2-2.0, P = 0.001). CONCLUSIONS Those undergoing open type I-III TAAA repair have similar rates of perioperative mortality and MAEs, regardless of sex. However, female sex is an independent risk factor for decreased long-term survival.

Abstract
OBJECTIVE Open repair of thoracoabdominal aortic aneurysms (TAAAs) that have developed secondary to chronic dissection (CD) is often more complex than repair of degenerative aneurysms (DAs). However, the literature is conflicted regarding the effect of CD on perioperative and long-term outcomes after open TAAA repair. The goal of this study was to determine whether CD predicts negative outcomes after TAAA repair. METHODS All open type I to type III TAAA repairs performed from 1987 to 2015 were evaluated using a single institutional database. End points included in-hospital death, spinal cord ischemia (SCI), major adverse events (MAEs), and long-term survival. Repairs performed for rupture or acute dissection were excluded. Univariate analysis was conducted using the Fisher's exact test for categorical variables and the Wilcoxon rank sum test for continuous variables. Logistic multivariable regression was used for the in-hospital end points, and survival analyses were performed with Cox proportional hazards modeling and Kaplan-Meier techniques. RESULTS During the study period, 453 patients underwent an intact open type I to type III TAAA repair. Ninety (20%) were performed for patients with CD. Those with CD were more likely to be younger (59 years vs 72 years; P < .001), to have an extent II lesion (30% vs 16%; P < .001), and to have Marfan syndrome (18% vs 0.6%; P < .001) and less likely to have coronary artery disease (28% vs 25%; P = .01) or chronic obstructive pulmonary disease (12% vs 27%; P = .004) compared with patients with DA. Twelve percent of patients with CD died perioperatively compared with 6% of those with DA (P = .03). Eighteen percent of CD patients suffered from SCI compared with 12% of DA patients (P = .2). Fifty-nine CD patients suffered a MAE compared with 42% of those with DA (P = .006). Multivariable analysis revealed CD to be an independent predictor of perioperative death (adjusted odds ratio [AOR], 3.1; 95% confidence interval [CI], 1.2-8.0; P = .02) with adjustment for age and Crawford extent. CD was also found to be independently predictive of any MAE (AOR, 2.5; 95% CI, 1.4-4.6; P = .002). CD was not associated with increased risk of SCI (AOR, 1.4; 95% CI, 0.6-3.2; P = .4). There was a long-term survival advantage in the CD cohort in the unadjusted analysis (log-rank, P = .009) but not in the adjusted analysis (CD adjusted hazard ratio, 0.9; 95% CI, 0.6-1.4; P = .7). CONCLUSIONS When analysis is limited to type I to type III TAAAs, open repair of patients with CD leads to increased perioperative mortality and morbidity compared with patients with DA. However, age-adjusted long-term survival is no different between the two cohorts.

Abstract
BACKGROUND No standard exists for the use of deceased donor liver biopsy during procurement. We sought to evaluate liver biopsy and the impact of findings on outcomes and graft utilization. METHODS A prospective observational study of donors after neurologic determination of death was conducted from 02/2012-08/2017 (16 OPOs). Donor data were collected through the UNOS Donor Management Goals Registry Web Portal and linked to the Scientific Registry of Transplant Recipients (SRTR) for recipient outcomes. Recipients of biopsied donor livers (BxDL) were studied and a Cox proportional hazard analysis was used to identify independent predictors of 1-year graft survival. RESULTS Data from 5449 liver transplant recipients were analyzed, of which 1791(33%) received a BxDL. There was no difference in graft or patient survival between the non-BxDL and BxDL recipient groups. On adjusted analysis of BxDL recipients, macrosteatosis (21%-30%[n = 148] and >30%[n = 92]) was not found to predict 1-year graft survival, whereas increasing donor age (HR1.02), donor Hispanic ethnicity (HR1.62), donor INR (HR1.18), and recipient life support (HR2.29) were. CONCLUSIONS Excellent graft and patient survival can be achieved in recipients of BxDL grafts. Notably, as demonstrated by the lack of effect of macrosteatosis on survival, donor to recipient matching may contribute to these outcomes.

Abstract
OBJECTIVE Patients with Marfan syndrome (MFS) often present with acute catastrophic aortic events at a young age and have a shortened life span. This study examines the impact of presentation and demographics on late survival in patients with MFS. METHODS Adults with confirmed MFS in our thoracic aortic center dataset were identified and statistical analysis performed to identify the incidence and predictors of aortic interventions and late mortality. RESULTS We identified 301 patients with a MFS initial diagnosis at age 17 years (interquartile range, 4-30 years) with presentation into our thoracic aortic center at 21 years (interquartile range, 8-34 years). The average follow-up in our center was 10 ± 10 years. Clinical features were 41% male, 86% white race, coronary artery disease 28%, hypertension 40%, peripheral vascular disease 19%, and anti-impulse agent in 51% (β-blocker, angiotensin-converting enzyme inhibitor/angiotensin receptor blocker, calcium channel blocker). Distribution of operative aortic pathology was isolated to the ascending aorta (70%) and descending aorta (8%). One hundred seventy-eight patients (59%) required primary aortic surgery (36% emergent). Primary procedures were cardiac (aortic valve/root) in nature in 94%. Seventy-four patients (42%) required multiple aortic procedures at a mean of 9.2 ± 6.9 years, involving the thoracoabdominal aorta in 65%, thoracic aorta in 37%, and abdominal aorta in 21%. Patients who required multiple aortic procedures were more likely (P < .05) to have coronary artery disease (50% vs 30%), and peripheral vascular disease (43% vs 18%). Multiple aortic procedures were also more likely (P < .05) in patients who developed de novo distal dissection (14% vs 0%), had prior dissection (47% vs 18%), or unknown MFS at the time of the initial procedure (27% vs 63%). Multivariable analysis identified prior dissection as an independent predictor of need for emergent surgery (odds ratio, 13.20; 95% confidence interval, 4.64-37.30; P < .05), as well as additional aortic surgery (odds ratio, 4.42; 95% confidence interval, 1.87-10.50; P < .05). Kaplan-Meier analysis showed similar 10-year survival with or without aortic interventions (82% with vs 89% without; P = .08). Late survival was decreased in patients undergoing emergent initial procedures (66% vs 89%; P < .01), as well as those undergoing multiple operations (74% vs 86%; P = .03). CONCLUSIONS These data indicate that, in the modern era, the mode of presentation and need for multiple procedures have a detrimental impact on late survival. Additionally, the presence of acute or chronic dissection predicts the need for additional aortic procedures during follow-up.

Abstract
OBJECTIVE The management of patients with carotid stenosis and symptomatic coronary artery disease (CAD) is challenging. This study assessed the impact of clinical coronary disease severity on carotid endarterectomy (CEA) with and without combined coronary artery bypass (CCAB). METHODS Using the Vascular Quality Initiative, patients with symptomatic CAD who underwent CCAB or isolated CEA (ICEA) from 2003 to 2017 were identified. Patients were stratified by CAD severity: stable angina (SA) and recent myocardial infarction/unstable angina (UA). Primary outcomes, including perioperative stroke, myocardial infarction (MI), and stroke/death/MI (SDM), were assessed between procedures within each CAD cohort. RESULTS There were 9098 patients identified: 887 CCAB patients (215 [24%] SA, 672 [76%] UA) and 8211 ICEA patients (6385 [78%] SA, 1826 [22%] UA). Overall, CCAB patients had higher rates of stroke (2.6% vs 1.3%; P = .002) and SDM (7.3% vs 3.5%, P < .001) but similar rates of MI (0.9% vs 1.6%; P = .12) compared with ICEA patients. In SA patients, no difference was seen in stroke (ICEA 1.2% vs CCAB 1.9%; P = .36), MI (1.3% vs 1.4%; P = .95), or SDM (2.9% vs 4.7%; P = .13). In UA patients, no difference was seen in stroke (ICEA 1.6% vs CCAB 2.8%; P = .06), but ICEA patients had higher rates of MI (2.4% vs 0.7%; P = .01) and CCAB patients had higher rates of SDM (8.2% vs 5.5%; P = .01). After logistic regression in the UA cohort, predictors of MI included ICEA (odds ratio [OR], 2.7; 95% confidence interval [CI], 1.1-7.0; P = .04) and carotid symptomatic status (OR, 2.1; 95% CI, 1.1-3.8; P = .01); carotid symptomatic status also predicted stroke (OR, 2.0; 95% CI, 1.1-3.6; P = .03), but CCAB did not. CONCLUSIONS In patients with symptomatic CAD, both clinical CAD severity and operative strategy affect outcomes. In SA patients, CCAB does not increase perioperative morbidity. However, CCAB in UA patients prevents MI while not appreciably increasing stroke risk. This suggests that coronary revascularization before or concomitant with CEA should be considered in UA patients but that prioritizing coronary intervention is less important in SA patients.
