Abstract
OBJECTIVE To determine the association of Enhanced Recovery Program (ERP) implementation with length of stay (LOS) and perioperative outcomes after lower-extremity bypass (LEB). BACKGROUND ERPs have been shown to decrease hospital LOS and improve perioperative outcomes, but their impact on patients undergoing vascular surgery remains unknown. METHODS Patients undergoing LEB who received or did not receive care under the ERP were included; pre-ERP (January 1, 2016-May 13, 2018) and ERP (May 14, 2018-July 31, 2022). Clinicopathologic characteristics and perioperative outcomes were analyzed. RESULTS Of 393 patients who underwent LEB [pre-ERP: n = 161 (41%); ERP: n = 232 (59%)], most were males (n = 254, 64.6%), White (n = 236, 60%), and government-insured (n = 265, 67.4%). Pre-ERP patients had higher Body Mass Index (28.8 ± 6.0 vs 27.4 ± 5.7, P = 0.03) and rates of diabetes (52% vs 36%, P = 0.002). ERP patients had a shorter total [6 (3-13) vs 7 (5-14) days, P = 0.01) and postoperative LOS [5 (3-8) vs 6 (4-8) days, P < 0.001]. Stratified by indication, postoperative LOS was shorter in ERP patients with claudication (3 vs 5 days, P = 0.01), rest pain (5 vs 6 days, P = 0.02), and tissue loss (6 vs 7 days, P = 0.03). ERP patients with rest pain also had a shorter total LOS (6 vs 7 days, P = 0.04) and lower 30-day readmission rates (32%-17%, P = 0.02). After ERP implementation, the average daily oral morphine equivalents decreased [median (interquartile range): 52.5 (26.6-105.0) vs 44.12 (22.2-74.4), P = 0.019], while the rates of direct discharge to home increased (83% vs 69%, P = 0.002). CONCLUSIONS This is the largest single-center cohort study evaluating ERP in LEB, showing that ERP implementation is associated with shorter LOS and improved perioperative outcomes.

Abstract
Iatrogenic aortic injury is a rare complication of laparoscopic nephrectomy with potentially catastrophic complications. Delays in recognition and treatment contribute significantly to patient morbidity and mortality. We present the case of a patient with acute limb ischemia and mesenteric ischemia secondary to partial transection of the supraceliac aorta during laparoscopic nephrectomy with a staple ligature. The injury was successfully treated with resection of the stapled aorta and reconstruction of a thoracoabdominal aortic bypass with a jump graft to the celiac artery.

Abstract
OBJECTIVE Aortic endarterectomy (AE), once a treatment of choice for aortoiliac occlusive disease, is now rarely performed in favor of endovascular procedures or open aortobifemoral bypass. However, in select patients with paravisceral or aortoiliac occlusive disease, AE remains a viable alternative for revascularization, either as a primary procedure or after prior interventions have failed. Here, we evaluated outcomes for an extended series of patients undergoing paravisceral or aortoiliac endarterectomy, demonstrating that these procedures can be an excellent alternative with acceptable morbidity and mortality in properly selected patients. METHODS A single institution retrospective review of 20 patients who underwent AE from 2017 to 2023 was performed. RESULTS Five patients (25%) underwent paravisceral endarterectomy and 15 (75%) underwent aortoiliac endarterectomy. There were no perioperative mortalities. One paravisceral patient died 3 months postoperatively from complications of pneumonia. Three patients in the paravisceral group required reinterventions; one acutely due to thrombosis of the superior mesenteric artery (SMA) requiring extension of the endarterectomy and patch angioplasty on postoperative day 0, one due to stenosis at the distal edge of the endarterectomy 1 month postoperatively, successfully treated with SMA stenting, and one at 10-month follow-up due to SMA stenosis at the distal aspect of the endarterectomy, also successfully treated with SMA stenting. With these reinterventions, the 1-year primary patency in the paravisceral group was 40%, primary-assisted patency was 80%, and secondary patency was 100%. In the aortoiliac group, 1-year primary, primary-assisted, and secondary patency were 91%, 91%, and 100%, respectively. One patient developed iliac thrombosis 10 days postoperatively owing to an intimal flap distal to the endarterectomy site. She and one other patient, a young man with an undefined hypercoagulable disorder, ultimately required neoaortoiliac reconstructions at 18 and 32 months postoperatively, respectively (the latter in the setting of stopping anticoagulation). The remaining 13 patients experienced no complications. All patients had rapid resolution of clinical symptoms, and median postoperative ankle-brachial indexes of 1.06 on the right and 1.00 on the left, representing a median improvement from preoperative ankle-brachial indexes of +0.59 on the right and +0.56 on the left (P < .01 and P < .01). CONCLUSIONS In this series of 20 patients undergoing paravisceral and infrarenal aortoiliac endarterectomy, AE was associated with no perioperative mortality, relatively low and manageable morbidity, and excellent clinical outcomes in patients with both paravisceral and aortoiliac occlusive disease. SMA-related early reintervention was not uncommon in the paravisceral group, and attention should be given particularly to the distal endarterectomy site. AE remains a viable treatment for severe multivessel paravisceral or aortoiliac occlusive disease isolated to the aorta and common iliac arteries in select patients.

Abstract
Revascularization of complex pelvic vascular anatomy presents an ongoing clinical challenge when treating aortoiliac disease. As vascular surgeons continue to intervene upon increasingly complex aortoiliac pathology, the role of pelvic revascularization is important for the preservation of pelvic organ function and prevention of devastating spinal cord ischemia. In this study we describe the indications, techniques, and clinical outcomes of a novel hybrid pelvic revascularization repair that focuses on optimizing revascularization while limiting pelvic surgical dissection during the management of complex aortic pathology in patients physiologically or anatomically unsuitable for traditional pelvic revascularization techniques.

Abstract
OBJECTIVE Hostile aortic neck anatomies such as proximal short necks are known to put patients at an increased risk for type IA endoleaks, migration, and need for reinterventions. The Heli-FX EndoAnchor System was designed to improve seal of aortic stent grafts. Endosuture aneurysm repair (ESAR) using EndoAnchors with the Endurant stent graft has been shown to be safe and effective for the treatment of patients with short necks through one year. This study reports the 5-year patient outcomes of the Aneurysm Treatment using the Heli-FX EndoAnchor System Global Registry (ANCHOR) short neck regulatory cohort. METHODS The 70 patients from the ANCHOR Registry were cohort submitted to regulators for approval of the Endurant short neck indication. Patients had an infrarenal neck length of ≥ 4 mm and <10 mm. At 5 years, this short neck cohort had clinical and imaging follow-up compliance rates of 85% (28/33) and 70% (23/33), respectively. RESULTS The short neck cohort had a mean age of 71.3±8.1 years and was 27.1% (19/70) female. Kaplan Meier freedom from all-cause mortality was 68.5 ± 6.2%, freedom from aneurysm-related mortality was 90.1 ± 4.5%, freedom from any endovascular or surgical secondary procedure was 76.9 ± 7.2%, and freedom from rupture was 95.6 ± 3.2%. Eight patients had a total of nine type IA endoleaks detected through 5 years, of which three resolved spontaneously by the next follow-up visit. There were two patients with renal complications who did not undergo reintervention and there were no device migrations reported through 5 years. After 5 years, 68.2% of patients (15/22) had sac regression, 13.6% (3/22) had stable sacs, and 18.2% (4/22) had increased sac diameter as compared with their 1-month measurements. CONCLUSIONS After ESAR treatment using Heli-FX EndoAnchors with Endurant, the 5-year outcomes of the short neck cohort from the ANCHOR registry had encouraging results with regards to proximal neck-related complications, secondary procedures, and sac regression. This review of ESAR in patients with short proximal necks showed positive outcomes through 5 years although follow-up of a larger cohort is necessary.

Abstract
BACKGROUND Enhanced recovery pathways (ERPs) aim to lower perioperative stress to facilitate recovery. Limited fasting combined with carbohydrate loading is a common ERP element. The effect of limited fasting has not been elucidated in patients with diabetes. Given the known deleterious effects of poor glycemic control in the perioperative period, such as increased rates of surgical site infection, the associations of preoperative limited fasting with perioperative glycemic control and early outcomes after lower extremity bypass (LEB) were investigated. METHODS A single institutional retrospective review of patients who underwent infrainguinal LEB from 2016 to 2022 was performed. The ERP was initiated in May 2018. Patients were stratified by diabetes diagnosis and preoperative hemoglobin A1C (HbA1C) levels. Perioperative glycemic control was compared between the limited fasting and traditional fasting patients (nil per os at midnight). Limited fasting was defined as a clear liquid diet until 2 hours before surgery with recommended carbohydrate loading consisting of 400 cc of a clear sports drink (approximately 30 g of carbohydrates). All limited fasting patients were within the ERP. Early perioperative hyperglycemia (EPH) was defined as blood glucose of >180 mg/dL within the first 24 hours of surgery. Perioperative outcomes such as surgical site infection, readmission, reinterventions, and complications were also compared. RESULTS A total of 393 patients were included (limited fasting patients N = 135; traditional fasting patients N = 258). A trend toward EPH was seen in all limited fasting groups. Evaluating limited fasting within diabetic patients revealed that 74.5% of limited fasting-diabetic patients had EPH compared with 49.6% of traditional fasting-diabetic patients (P = .001). When stratified by the HbA1C level, a significantly higher rate of EPH was seen in the HbA1c >8.0% groups, with 90.5% in the limited fasting patients compared with 67.9% in traditional fasting patients (P = .05). Limited fasting-diabetic patients experience a longer postoperative length of stay at 5.0 days (interquartile range: 3, 9) vs 4.0 days (2, 6) in nondiabetic patients (P = .016). CONCLUSIONS ERP limited fasting was associated with early perioperative hyperglycemia after LEB, particularly in patients with HbA1C >8.0%. Due to the high prevalence of diabetic patients undergoing LEB under ERP, the role of limited fasting and common glycemic elements of ERP may need to be re-evaluated in this subpopulation.

Abstract
Atherosclerotic carotid artery disease has been well studied over the last half-century by multiple randomized controlled trials attempting to elucidate the appropriate modality of therapy for this disease process. Surgical techniques have evolved from carotid artery endarterectomy and transfemoral carotid artery stenting to the development of hybrid techniques in transcarotid artery revascularization. In this article, the authors provide a review of the available literature regarding operative and medical management of carotid artery disease.

Abstract
BACKGROUND In this study, pre-operative medical complexity is estimated by the independently validated Vascular Quality Initiative VQI Cardiac Risk Index (CRI). This study aims to identify and correlate trends of CRI for open abdominal aortic aneurysm (OAR) with trends in the CRI for corresponding endovascular aortic repair (EVAR). This assessment of differences in estimated procedural risks will be used to support the theory that, patient migration is an important factor contributing to decreased POMI following open vascular procedures. METHODS A retrospective review of VQI data from 2003 to 2020 for all patients undergoing elective aortic repairs (OAR and EVAR) was conducted. The CRI scoring developed for the open repair (oCRI) was applied to both the OAR and EVAR cohorts, with variables specific to EVAR translated from similar open repair factors in the model where feasible. To evaluate for changes across time, patients were grouped into Eras based on year of procedure, subsequently, univariate analysis of post-operative myocardial infarction (POMI) rates and CRI scores were perfomed between each era. RESULTS A total of 56,067 elective aortic repairs were identified (83% EVAR, 17% OAR). Within the OAR cohort, the average oCRI estimate was 7.1% with significant decrease across the studied timeframe (8% ± 4.6%→6.9% ± 4.4%, P < 0.001), which corresponded to a significant decrease in observed clinical myocardial infarction (MI) rate (4.1%→1.4%, P < 0.001). Over that same time period, the open CRI was applied to the EVAR cohort, and the average oCRI estimate was 7.2% and showed a significant increase (6.6% ± 2.8%→7.2% ± 4.4%, P < 0.001). Within the EVAR cohort, the eCRI estimate did not show any significant changes over time (average 0.48%), while the actual rate of clinical MI showed a significant decrease (1.1%→0.3%, P = 0.002). Gap analysis was conducted within the EVAR cohort between CRI estimates of procedural risks from an open operation versus an EVAR, which demonstrated that patients within the EVAR cohort would, on an average, has had 6.7% higher risk of POMI had they undergone an open procedure. CONCLUSIONS Paradigm shifts with regard to patient selection for aortic repair is evident within this large national cohort. Over time, OAR patients had fewer preoperative estimated cardiac comorbidities and there is a corresponding decrease in POMI rates. As high-risk patients migrate from OAR to EVAR, there has been a subsequent increase in EVAR estimated pre-operative risks as the patients become more medically high-risk. Despite increasing complexity, rates of POMI in EVAR significantly decreased, potentially explained by improved operative technique and peri-operative care.

Abstract
BACKGROUND Aortic remodeling of the thoracic aorta has been studied in patients treated with medical or endovascular therapy for the treatment of acute aortic dissections; however, particular attention has not yet focused on identifying specific growth patterns and rates across all aortic zones. Additionally, previous studies have not delineated between dissections with and without visceral aortic involvement, and we hypothesize that these two cohorts may exhibit distinct differences. The aim of this study is to investigate aortic behavior over time in medically managed acute SVS/STS Type B dissections with visceral aortic involvement, and identify potential associations of subsequent aortic behavior with clinical outcomes. METHODS A single-center retrospective review was performed of all patients between 2010-2020 with acute SVS/STS Type B aortic dissections with visceral aortic involvement that were not surgically managed. Short-axis centerline measurements of the true/false lumen and total aortic diameter (TAD) were taken at standardized locations relative to aortic anatomy within each aortic zone, including non-dissected zones. Measurements were taken at the time of diagnosis and at six subsequent yearly intervals. Diameter changes over time were evaluated using repeated measures mixed models linear growth analysis. Aortic enlargement was classified by growth in TAD≥5mm in either the thoracic (Thoracic Segment Enlargement [TSE], Zone 0-4) or visceral segments (Visceral Segment Enlargement [VSE], Zone 5-9). RESULTS A total of 78 patients were identified with a median length of follow-up of 3.3 years (interquartile range [IQR]1.3-6.6 years). Follow-up past 5 years was seen in 31% of the cohort. For the entire cohort, mean thoracic growth in TAD was 2.0±2.0 mm/year and visceral growth in TAD 2.5±2.4 mm/year. TSE was observed in 65% of patients, with a median time until onset of 0.8 years (IQR 0.4-2.3 years). VSE was observed in 57% of the cohort, with a median time until onset of 1.6 years (IQR 0.9-3.3 years). Repeat measures mixed models linear growth analysis identified significant predictable linear growth in all aortic zones except for the non-dissected Zones 0-2. Odds for TSE are significantly increased in patients with known genetically triggered aortic conditions (GenTACs) (OR 2, 95% CI 1.8-4.5, p=0.044) and in cases where the dissection entry tear was in either Zone 1 or 2 (OR 4.8, 95% CI 1.2-8.4, p=0.044). In adjusted regression analysis, odds for intervention in the thoracic aorta were significantly increased in patients with rapid TSE in Zone 3 (OR 3.6 [1.1-8.4], p=0.045). Similarly, odds for intervention targeting the visceral aortic segment were significantly increased in patients with Zone 9 VSE (OR 9.3, 95% CI 1.1-13.3, p=0.014). Odds for 5-year all-cause mortality were significantly increased in cases with large thoracic aneurysms (OR 6.1, 95% CI 1.1-14.9, p=0.042). CONCLUSIONS Aortic enlargement was present in the majority of patients with medically managed acute SVS/STS Type B aortic dissections with visceral aortic involvement, with analysis demonstrating predictable linear growth in all dissected zones. Patients with aortic instability demonstrated higher gross changes in diameter in addition to higher yearly rates of change compared to all comers. Odds for enlargement were impacted by both patient demographic and anatomic dissection characteristics. Growth in Zone 3 and Zone 9 significantly increased odds for aortic intervention. Odds for 5-year mortality were significantly increased in the presence of large thoracic aneurysms. Results highlight risk of progressive degeneration beyond acute phase in SVS/STS Type B aortic dissections with visceral aortic involvement, with life-long surveillance remaining crucial in management of dissections.

Abstract
OBJECTIVES Statin therapy has been associated with improved clinical outcomes in patients undergoing treatment for vascular disease. Current guidelines do not address statin therapy in isolated abdominal aortic aneurysm (AAA) in the absence of other atherosclerotic cardiovascular disease (ASCVD). This study aims to elucidate effects of statin therapy, either as monotherapy or combined with antiplatelet agents, on the long-term mortality of patients with and without ASCVD who undergo elective AAA repair. METHODS A retrospective review was performed on all AAA patients treated electively with endovascular (EVAR) and open aortic repair (OAR) in the Society for Vascular Surgery Vascular Quality Initiative from 2003-2020. Long-term mortality was evaluated based on the presence of statin and antiplatelet medication use at discharge stratified by those with and without a history of ASCVD. Unadjusted survival was estimated by Kaplan Meier methodology. Cox proportional hazards modeling was used to determine mortality risk after adjusting for key factors. RESULTS A total of 47,012 AAA repairs were selected for analysis: 80.7% EVAR (N=40,153) and 19.3% OAR (N=6,859). EVAR patients on combined statin/antiplatelet (AP) therapy had significantly better survival irrespective of whether they had known ASCVD. In the presence of ASCVD, EVAR patients on statin alone had improved survival compared to those not on a statin (10.9±0.5 vs 10.5±0.4 years, Log Rank <.001), with survival being even greater among those receiving combined statin/AP therapy (12.2±0.2 vs 10.5±0.4 years, Log Rank <.001). In the absence of ASCVD, EVAR patients on statin alone also had better mean survival compared to patients not on a statin (8.7±0.5 vs 8.4±0.4 years, Log Rank<.001), with higher survival among statin/AP therapy patients (9.4±0.2 years vs 8.7±0.5 years, Log Rank <.001). Comparison of adjusted survival via Cox multivariable regression demonstrated a protective effect of statins (HR=0.737, p=0.04, vs no medication) and combined statin/AP therapy (HR=0.659, p=0.001, vs no medication) in patients with ASCVD history. A similar protective effect (statin: HR 0.826, p=0.05. Combination statin/AP: HR 0.726, p<.001, vs no medication) was identified in patients without ASCVD history. Within the OAR cohort, statin therapy was not associated with improved survival among patients without ASCVD; however, combined statin/AP therapy had a protective effect for patients with a known ASCVD diagnosis. Based on KM analysis, OAR patients with ASCVD on combined statin/AP therapy had significantly higher mean survival compared to isolated statin therapy (12.7±0.2 vs 10.3±0.65 years) and no medical therapy (10.5±0.8 years, Log Rank <.001). In KM analysis, OAR patients without known ASCVD indications (N=3591) had no significant survival differences based on the presence of combined statin/AP therapy (8.4 ± .07 vs. 8.5 ± .11 years, Log Rank=.638). CONCLUSION Isolated statin therapy and combined statin/AP therapy showed significant survival benefit in all EVAR and OAR patients with ASCVD indications, as well as among EVAR patients without a known ASCVD diagnosis. OAR patients without ASCVD did not have a significant survival benefit from statin therapy, but low numbers in this group may have confounded the findings. Combined statin/AP therapy appears to have significant post-repair survival benefits even in isolated AAA without ASCVD, as demonstrated in post-EVAR patients in this study. Expansion of statin use recommendations within aneurysm treatment guidelines may be warranted.

Abstract
BACKGROUND Spinal cord ischemia (SCI) is a dreaded complication of thoracic and complex endovascular aortic repair (TEVAR/cEVAR). Controversy exists surrounding cerebrospinal fluid drain (CSFD) use, especially preoperative prophylactic placement, owing to concerns regarding catheter-related complications. However, these risks are balanced by the widely accepted benefits of CSFDs during open repair to prevent and/or rescue patients with SCI. The importance of this issue is underscored by the paucity of data on CSFD practice patterns, limiting the development of practice guidelines. Therefore, the purpose of the present analysis was to evaluate the differences between patients who developed SCI despite preoperative CSFD placement and those treated with therapeutic postoperative CSFD placement. METHODS All elective TEVAR/cEVAR procedures for degenerative aneurysm pathology in the Society for Vascular Surgery Vascular Quality Initiative from 2014 to 2019 were analyzed. CSFD use over time, the factors associated with preoperative prophylactic vs postoperative therapeutic CSFD placement in patients with SCI (transient or permanent), and outcomes were evaluated. Survival differences were estimated using the Kaplan-Meier method. RESULTS A total of 3406 TEVAR/cEVAR procedures met the inclusion criteria, with an overall SCI rate of 2.3% (n = 88). The SCI rate decreased from 4.55% in 2014 to 1.43% in 2018. Prophylactic preoperative CSFD use was similar over time (2014, 30%; vs 2018, 27%; P = .8). After further exclusions to evaluate CSFD use in those who had developed SCI, 72 patients were available for analysis, 48 with SCI and prophylactic CSFD placement and 24 with SCI and therapeutic CSFD placement. Specific to SCI, the patient demographics and comorbidities were not significantly different between the prophylactic and therapeutic groups, with the exception of previous aortic surgery, which was more common in the prophylactic CSFD cohort (46% vs 23%; P < .001). The SCI outcome was significantly worse for the therapeutic group because 79% had documented permanent paraplegia at discharge compared with 54% of the prophylactic group (P = .04). SCI patients receiving a postoperative therapeutic CSFD had had worse survival than those with a preoperative prophylactic CSFD (50% ± 10% vs 71% ± 9%; log-rank P = .1; Wilcoxon P = .05). CONCLUSIONS Prophylactic CSFD use with TEVAR/cEVAR remained stable during the study period. Of the SCI patients, postoperative therapeutic CSFD placement was associated with worse sustained neurologic outcomes and overall survival compared with preoperative prophylactic CSFD placement. These findings highlight the need for a randomized clinical trial to examine prophylactic vs therapeutic CSFD placement in association with TEVAR/cEVAR.

Abstract
BACKGROUND The American Heart Association guidelines instruct use of postoperative telemetry (POT) should be reserved for patients undergoing cardiac procedures and/or those with ischemic cardiac symptoms, but acknowledge that major vascular procedures deserve unique consideration. Telemetry remains a limited resource in many hospitals; however, it has been poorly defined which vascular patients have greatest need for POT. The purpose of this study is to define the rates of postoperative arrhythmias (POAs) after major vascular operations using the Society for Vascular Surgery Vascular Quality Initiative (VQI) registry, identify independent predictors of POA, and determine the effect of POA on mortality to guide the use of POT in vascular patients. METHODS A retrospective cohort study was performed using the following VQI modules: open abdominal aortic aneurysm repair (oAAA), complex endovascular aneurysm repair (EVAR) (thoracic endovascular aortic repair [TEVAR]/c-EVAR), EVAR, suprainguinal bypass (SIB), and infrainguinal bypass (IIB). POA was defined in the VQI as a new rhythm disturbance requiring treatment with medication or cardioversion. The incidence of POA, preoperative risk factors, and demographics were determined for each procedure. RESULTS A total of 121,652 procedures were identified with an overall POA event rate of 5.1% (n = 6,265). Procedure-specific event rates for POA among VQI registries are as follows: oAAA 14.4%, TEVAR/c-EVAR 8.5%, EVAR 2.7%, SIB 6.2%, and IIB 3.8%. Across all procedure types, POA was associated with emergent operations and increased procedure time. Procedure-specific multivariable regression revealed additional independent preoperative intraoperative factors associated with POA that were unique with each procedure. Across all procedural groups, the presence of POA was associated with increased rates of clinical myocardial infarction and decreased survival on Kaplan-Meier analysis. CONCLUSIONS Rates of POA in patients undergoing vascular procedures appear higher than previously reported, and POA is associated with decreased survival. Our study elucidated patient- and procedure-specific predictor factors associated with POA that can be used to inform the use of POT.

Abstract
OBJECTIVE Thoracofemoral bypass (TFB) has been used infrequently but is an alternative for select patients with aortoiliac occlusive disease. Limited data are available in the reported data regarding TFB, with all studies small, single-center series. We aimed to describe the perioperative and long-term survival, patency, and rate of major perioperative complications after TFB in a large national registry. METHODS The Vascular Quality Initiative suprainguinal bypass module was used to identify patients who had undergone TFB for occlusive disease from 2009 to 2019. A descriptive analysis was performed to provide the rates of survival, patency, major complications, and freedom from major amputation in the perioperative period and at 1 year of follow-up. Major complications were compared by procedure indication, with categorical variables analyzed using χ2 tests and continuous variables using analysis of variance. Kaplan-Meier curve analysis was used to estimate survival at the 1- and 5-year follow-up intervals and freedom from major amputation at 1 year. RESULTS A total of 154 TFB procedures were identified. Of the 154 patients, 59 (38.3%) had undergone previous inflow bypass and 22 (14.2%) had undergone previous leg bypass. The procedure indications included claudication (n = 66; 42.9%), rest pain (n = 59; 38.3%), tissue loss (n = 19; 12.3%), and acute limb ischemia (n = 10; 6.5%). Major complications (eg, wound infection, respiratory, major stroke, new dialysis, cardiac, embolic, major amputation, occlusion) occurred in 31.2% of the cohort. When examined by indication, the acute limb ischemia and claudication cohorts had an increased rate of major complications (acute limb ischemia, 60.0%; claudication, 34.8%; critical limb ischemia, 24.4%; P = .05). The survival rate at 30 days was 95.5%, with a Kaplan-Meier estimated 1-year survival rate of 92.7% ± 2.2%. Primary patency at discharge from the index hospitalization was 92.9% and 89.0% at 1 year. Postoperative major amputation was required for 1 patient during the index hospitalization, for a Kaplan-Meier estimated freedom from major amputation at 1 year of 97.1% ± 2.2%. Two patients developed in-hospital bypass occlusion and three patients developed occlusion within 1 year, for an overall freedom from occlusion rate of 96.8% at 1 year. CONCLUSIONS TFB is associated with a high rate of perioperative major complications; however, the long-term survival and patency after TFB remained acceptable when performed for limb salvage. The high perioperative complication rates of TFB procedures performed for claudication suggest TFB should be used rarely in this population. These data can be used to counsel patients and aid in decision making before operative intervention.

Abstract
We review and expand on our work to impose constraints on the effective Kohn-Sham (KS) potential of local and semi-local density-functional approximations. Constraining the minimisation of the approximate total energy density-functional invariably leads to an optimised effective potential (OEP) equation, the solution of which yields the KS potential. We review briefly our previous work on this and demonstrate with numerous examples that despite the well-known mathematical issues of the OEP with finite basis sets, our OEP equations are numerically robust. We demonstrate that appropriately constraining the 'screening charge' which corresponds to the Hartree, exchange and correlation potential not only corrects its asymptotic behaviour but also allows the exchange and correlation potential to exhibit a non-zero derivative discontinuity, a feature of the exact KS potential that is necessary for the accurate prediction of band-gaps in solids but very hard to capture with semi-local approximations.

Abstract
OBJECTIVE Traditional open surgical repair of thoracoabdominal aortic aneurysms (TAAAs) has historically resulted in 30-day mortality rates ranging from 6% to 20%, depending on the Crawford anatomic extent. Although short-term survival is important, long-term survival is essential for patients to benefit from these often elective and potentially morbid procedures. The aneurysm extent affects the long-term survival after open repair; however, effect on endovascular repair is unknown and could influence the decision process for repair. We evaluated the association between aneurysm extent and survival and identified patient and perioperative factors associated with mortality after endovascular repair. METHODS A retrospective cohort of patients treated for TAAAs recorded in the Society for Vascular Surgery Vascular Quality Initiative thoracic and complex endovascular aneurysm repair registry were evaluated. All patients treated for asymptomatic degenerative aneurysms from 2010 to 2019 were included. Crawford extent I to V was defined according to the proximal and distal landing zones documented in the registry. Patients without extension into the visceral aorta were used for comparison and categorized as having extent 0a or 0b, depending on the distal landing zone in the thoracic aorta. Kaplan-Meier plots were used to estimate survival, and Cox proportional hazard regression models were created to identify the predictors of mortality. RESULTS From 2010 to 2019, 15,333 patients were entered into the registry, of whom 2062 met the inclusion criteria. The Crawford extent was 0a for 379, 0b for 848, I for 81, II for 98, III for 130, IV for 454, and V for 72. Three groups were created in accordance with the similar outcomes noted on a preliminary analysis: (1) extent 0a and 0b; (2) extent I, II, and III; and (3) extent IV and V. The mean survival time for the extent 0a and 0b group was 70.7 ± 1.43 months and was 48.6 ± 1.65 months for the extent I, II, and III group and 57.6 ± 1.24 months for the extent IV and V group. The corresponding 1-year mortality was 8.4%, 18.4%, and 7.8%. Cox regression analysis identified the following preoperative factors were associated with mortality: chronic obstructive pulmonary disease (odds ratio [OR], 1.70; P < .001), Crawford extent I to III (OR, 1.64; P = .015), preexisting chronic kidney disease (OR, 1.37; P = .024), and age per year (OR, 1.03; P < .001). A number of postoperative factors were also associated with mortality. CONCLUSIONS Similar to open TAAA repair, patients with more extensive aortic disease treated with endovascular repair had worse 1-year and long-term survival. The extent of aortic disease and anticipated postoperative survival should factor prominently into the surgical decision-making process for elective endovascular TAAA repair.

Abstract
BACKGROUND Vascular surgery has seen rapid increase in the use of less invasive endovascular therapies along with advancements in cardiac perioperative optimization in the past 2 decades. However, a recent American College of Surgeons National Surgical Quality Improvement Program database study found no improvement in postoperative myocardial infarction (POMI) over a 10-year period in high-risk procedures. The national Society for Vascular Surgery Vascular Quality Initiative (VQI) registry provides a more in-depth characterization of vascular surgery procedures. Here, we sought to evaluate long-term trends in POMI using VQI registry data for patients undergoing carotid endarterectomy (CEA), thoracic endovascular aortic repair (TEVAR), endovascular aortic repair (EVAR), open abdominal aortic aneurysm repair (oAAA), suprainguinal bypass (SIB), and infrainguinal bypass (IIB). METHODS A retrospective cohort study was performed using data on elective procedures from 2003 to 2017. Procedures were subdivided by date of operation into 3-year era consecutive groups for subanalysis (2003-05, 2006-08, 2009-11, 2012-14, and 2015-17). The incidence of POMI, preoperative risk factors (including individual patient VQI cardiac risk index (CRI)), and demographics were determined over time. RESULTS A total of 227,837 elective procedures were identified: CEA (n = 88,805, 39.0%), TEVAR (n = 7,494, 3.3%), EVAR (n = 34,376, 15.1%), oAAA (n = 7,568, 3.3%), SIB (n = 11,354, 5.0%), and IIB (n = 34,661, 15.2%). Across all procedures, the overall rate of POMI was 1.3%. POMI rates from 2003-05 to 2015-17 for CEA decreased from 0.9% to 0.7% (P = 0.21), EVAR from 2.0% to 0.7%, P = 0.003, oAAA from 6.8% to 5.1% (P = 0.12), and IIB from 3.8% to 2.4% (P = 0.003). SIB POMI decreased from 3.06% to 2.95%, P = 0.85 from 2009 to 17. While POMI after TEVAR increased from 2.40% to 2.56% from 2009 to 17, P = 0.91. Over these same time periods, only EVAR and IIB had a reduction in CRIs (P = 0.059 and P < 0.001, respectively). CEA, EVAR, IIB, and oAAA all showed a significant (P < 0.001) increase in preoperative statin use. CONCLUSIONS Except for TEVAR, the incidence of POMI has remained unchanged or decreased over the past 15 years in VQI registries. Patients undergoing IIB and EVAR demonstrated decreases in POMI rates that correspond with a reduction in CRIs and increased preoperative statin use. CEA and SIB had no significant change in POMI rates nor CRIs. The etiology of decreased POMI rate is uncertain, but increasing statin use, patient-specific factors, and patient selection for procedures may be important drivers of this improvement.

Abstract
BACKGROUND Although endovascular peripheral vascular interventions (PVI) are typically limited to vessels above the knee in intermittent claudication (IC), some patients have concomitant or isolated infrapopliteal disease with IC. The benefits and risks of undergoing tibial intervention remain unclear in IC patients. The purpose of this study is to evaluate the prevalence and outcomes of infrapopliteal PVI for IC. METHODS The Vascular Quality Initiative was queried for PVI procedures performed for IC between 2003 and 2018. Patients were divided into 3 groups: isolated femoropopliteal (FP), isolated infrapopliteal (IP), and combined above and below knee interventions (COM). Multivariable logistic regression models identified predictors of minor and major amputation, as well as freedom from reintervention. Kaplan-Meier plots estimate amputation-free survival. RESULTS We identified 34,944 PVI procedures for IC. There were 31,110 (89.0%) FP interventions, 1,045 (3.0%) IP interventions, and 2,789 (8.0%) COM interventions. Kaplan-Meier plots of amputation-free survival revealed that patients with any IP intervention had significantly higher rates of both minor and major amputation (log rank <0.001). Freedom from reintervention at 1-year was 89.2% for the FP group, 91.3% for the IP group, and 85.3% for the COM group (P < 0.0001). In multivariable analysis, factors associated with an increased risk of major amputation included isolated IP intervention (OR 6.47, 95% CI, 6.45-6.49; P < 0.0001), COM interventions (OR 2.32, 95% CI, 2.31-2.33; P < 0.0001), dialysis dependence (OR 3.34, 95% CI, 3.33-3.35; P < 0.0001), CHF (OR 1.86, 95% CI, 1.85-1.86; P = 0.021) and, nonwhite race (OR 1.64, 95% CI, 1.63-1.64; P = 0.013). CONCLUSIONS PVI in the infrapopliteal vessels for IC is associated with higher amputation rates. This observation may suggest the need for more careful patient selection when performing PVI in patients with IC where disease extends into the infrapopliteal level.

Abstract
OBJECTIVE Enhanced recovery programs (ERPs) have gained wide acceptance across multiple surgical disciplines to improve postoperative outcomes and to decrease hospital length of stay (LOS). However, there is limited information in the existing literature for vascular patients. We describe the implementation and early results of an ERP and barriers to its implementation for lower extremity bypass surgery. Our intention is to provide a framework to assist with implementation of similar ERPs. METHODS Using the plan, do, check, adjust methodology, a multidisciplinary team was assembled. A database was used to collect information on patient-, procedure-, and ERP-specific metrics. We then retrospectively analyzed patients' demographics and outcomes. RESULTS During 9 months, an ERP (n = 57) was successfully developed and implemented spanning preoperative, intraoperative, and postoperative phases. ERP and non-ERP patient demographics were statistically similar. Early successes include 97% use of fascia iliaca block and multimodal analgesia administration in 81%. Barriers included only 47% of patients achieving day of surgery mobilization and 19% receiving celecoxib preoperatively. ERP patients had decreased total and postoperative LOS compared with non-ERP patients (n = 190) with a mean (standard deviation) total LOS of 8.32 (8.4) days vs 11.14 (10.1) days (P = .056) and postoperative LOS of 6.12 (6.02) days vs 7.98 (7.52) days (P = .089). There was significant decrease in observed to expected postoperative LOS (1.28 [0.66] vs 1.82 [1.38]; P = .005). Variable and total costs for ERP patients were significantly reduced ($13,208 [$9930] vs $18,777 [$19,118; P < .01] and $29,865 [$22,110] vs $40,328 [$37,820; P = .01], respectively). CONCLUSIONS Successful implementation of ERP for lower extremity bypass carries notable challenges but can have a significant impact on practice patterns. Further adjustment of our current protocol is anticipated, but early results are promising. Implementation of a vascular surgery ERP reduced variable and total costs and decreased total and postoperative LOS. We believe this protocol can easily be implemented at other institutions using the pathway outlined.

Abstract
OBJECTIVE Previous publications have clearly established a correlation between timing of thoracic endovascular aortic repair (TEVAR) and complications after treatment of complicated acute type B aortic dissection (ATBAD). However, the temporal association of TEVAR with morbidity after uncomplicated presentations is poorly understood and has not previously been examined using real-world national data. Therefore, the objective of this analysis was to determine whether TEVAR timing of uncomplicated ATBAD (UATBAD) is associated with postoperative complications. METHODS The Vascular Quality Initiative TEVAR and complex endovascular aneurysm repair registry was analyzed from 2010 to 2019. Procedures performed for non-dissection-related disease as well as for ATBAD with malperfusion or rupture were excluded. Because of inherent differences between timing cohorts, propensity score matching was performed to ensure like comparisons. Univariate and multivariable analysis after matching was used to determine differences between timing groups (symptom onset to TEVAR: acute, 1-14 days; subacute, 15-90 days) for postoperative mortality, in-hospital complications, and reintervention. RESULTS A total of 688 cases meeting inclusion criteria were identified. After matching 187 patients in each of the 1- to 14-day and 15- to 90-day treatment groups, there were no statistically significant differences between groups. On univariate analysis, the 1- to 14-day treatment group had a higher proportion of cases requiring reintervention within 30 days (15.3%) compared with UATBAD patients undergoing TEVAR within 15 to 90 days (5.2%; P = .02). There was also a difference (P = .007) at 1 year, with 33.8% of the 1- to 14-day UATBAD patients undergoing reintervention compared with 14.5% for the 15- to 90-day group. There were no statistically significant differences on multivariable analysis for long-term survival, complications, or long-term reintervention. There was a trend toward significance (P = .08) with the 1- to 14-day group having 2.3 times the odds of requiring an in-hospital reintervention compared with the 15- to 90-day group. CONCLUSIONS Timing of TEVAR for UATBAD does not appear to predict mortality or postoperative complications. However, there is a strong association between repair within 1 to 14 days and higher risk of reintervention. This may in part be related to the 1- to 14-day group's representing an inherently higher anatomic or physiologic risk population that cannot be entirely accounted for with propensity analysis. The role of optimal timing to intervention should be incorporated into future study design of TEVAR trials for UATBAD.

Abstract
BACKGROUND Vein conduit is known to have better patency than prosthetic for infrainguinal bypass. Here we explore if racial disparities exist in infrainguinal bypass vein conduit use amid preoperative patient and systemic factors. METHODS Retrospective Society for Vascular Surgery Vascular Quality Initiative data for 23,959 infrainguinal bypasses between 2003 and 2017 for occlusive disease were analyzed. For homogeneity, only infrainguinal bypasses originating from the common femoral artery were included. Demographics of patients receiving vein vs prosthetic were compared and logistic regression analyses were performed with race and preoperative factors to evaluate for predictors of vein conduit use. RESULTS Adjusted regression models demonstrated black patients were 76% as likely (p < .001) and Hispanic patients 79% as likely (p = .003) to have vein conduit compared to white patients. Factors positively correlating with vein use included vein mapping, more distal bypass target, tissue loss or acute ischemia bypass indications, commercial insurance, and weight. Factors against vein use included advanced age, female gender, ASA class 4, urgent procedure, preoperative mobility limitation, prior CABG or leg bypass, prior smoking, preoperative anticoagulation, and a bypass performed in the Southern US or before 2012. While black and Hispanic patients were less likely to receive vein, they were vein mapped at similar or higher rates than other groups. CONCLUSION Racial disparities exist in conduit use for infrainguinal bypass, with black and Hispanic patients less likely to receive vein bypasses. However, the contribution of race to conduit selection is small in adjusted and unadjusted models. Overall, pre-operative variables in the Vascular Quality Initiative poorly predicted vein conduit use for infrainguinal bypass.

Abstract
BACKGROUND Fenestrated and branched endovascular aortic repair (F/BEVAR) is increasingly used to manage pararenal and thoracoabdominal aortic disease (TAAA). Device-related reintervention after F/BEVAR is common, but little is known about its impact on postoperative mortality. The purpose of this analysis was to describe secondary intervention (SI) after F/BEVAR and determine the impact of these procedures on patient survival. METHODS A single-center review was done on all consecutive F/BEVARs performed from 2010 to 2016. Primary end points were incidence of secondary aortic, branch, and/or access vessel‒related SI, and survival. SI was categorized as minor endovascular (branch restenting, access vessel treatment, or percutaneous coil embolization), major endovascular (new aortic graft placement), or open (bleeding, access vessel, and/or aortic). Kaplan-Meier methodology was used to estimate freedom from SI and survival. Multivariable analysis was used to identify predictors of SI. RESULTS A total of 308 F/BEVAR procedures were performed (75% physician-modified, 18% custom, 7% Zfen), with 1022 vessels revascularized (celiac, 228; superior mesenteric artery [SMA], 263; renal, 525). There were 117 (39%) extent I-III TAAA, 132 (44%) extent IV TAAA/4-vessel pararenal, and 54 (18%) <4-vessel pararenal repairs performed. Any type of SI occurred in 24% (74) of patients during the mean follow-up of 20 ± 21 months. The majority of reinterventions were endovascular (minor, 53% [n = 39]; major, 32% [n = 24]), whereas 12% (n = 9) were open and 3% (n = 2) hybrid. Primary indication for SI included: 22 (29%) with branch-related endoleaks (1C or III); 15 (22%) with proximal or distal aortic degeneration; 8 (12%) with branch vessel thrombosis/stenosis; 10 (11%) with aortic device type III endoleak/loss of overlap; 4 (6%) with postoperative mesenteric or renal bleeding events; 5 (5%) with type II endoleak; 3 (5%) with access vessel complication; and 2 (3%) with graft infection. Most SIs were elective (65%; n = 48) with the remainder occurring emergently (24%; n = 18) or for symptoms/urgently (11%; n = 8). Compared with endovascular remediation, open SI was more likely to be emergent (89%, 8 of 9; P = .001). Freedom from SI was 80 ± 3% and 64 ± 4% at 1 and 3 years, respectively. One- and 5-year survival with or without SI was: 1 year, 88 ± 4% vs 81 ± 3%; 5 years, 76 ± 5% vs 59 ± 4% (log rank test, P = .06). There was no survival difference based on type of SI (log rank test, P = .3). Extent I-III TAAA (HR, 1.6; 95% CI, 0.98-3.3; P = .06) and history of cerebrovascular disease (HR, 1.8; 95% CI, 0.97-2.6; P = .07) were predictive of SI. CONCLUSIONS SIs after F/BEVAR most frequently involve branch vessel or aortic device remediation procedures; however, they do not negatively impact out-of-hospital survival. These results further highlight the crucial role of imaging surveillance after F/BEVAR to maintain durability. Discussions with patients, periprocedural planning, and the next generation of device design must focus on issues surrounding the risk of device-related SI events.

Abstract
INTRODUCTION Type 2 endoleaks (T2Es) after endovascular repair (EVAR) of abdominal aortic aneurysm (AAA) can lead to sac expansion or failure of sac regression, and often present as a management dilemma. The intraluminal thrombus (ILT) may influence the likelihood of endoleaks after EVAR and can be characterized using routine preoperative imaging. We examined the relationship between preoperative spatial morphology of ILT and the incidence of postoperative T2E. METHODS All patients who underwent EVAR at the John Radcliffe Hospital (Oxford, UK) were prospectively entered in a clinical database. Computed tomography angiograms (CTAs) were performed as part of routine clinical care. The ILT morphology of each patient was determined using the preoperative CTA. Arterial phase cross-sectional images of the AAA were analyzed according to the presence and morphology of the thrombus in each quadrant. The overall ILT morphology was defined by measurements obtained over a 4-cm segment of the AAA. The diagnosis of T2Es during EVAR surveillance was confirmed by CTAs. The relation between the ILT morphology and T2E was assessed using logistic regression. RESULTS Between September 2009 and July 2016, 271 patients underwent EVAR for infrarenal AAAs (male: 241, age = 79 ± 7). The ILT was present in 265 (98%) of AAAs. Mean follow-up was 1.9 ± 1.6 years. The T2E was observed in 77 cases. Sixty-one percent of T2Es were observed within the first week after surgery. The T2E was observed in 50% (3/6) of cases without the ILT (no-ILT). Compared with no-ILT, the presence of circumferential or posterolateral ILTs was protective from T2Es (odds ratio = 0.33 and 0.37; P = 0.002 and P = 0.047, respectively). CONCLUSIONS The spatial ILT morphology on routine preoperative CTA imaging can be a biomarker for post-EVAR T2Es. ILTs that cover the posterolateral aspects of the lumen, or circumferential ILTs, are protective of T2Es. This information can be useful in the preoperative planning of EVARs.

Abstract
Acceptance of endovascular technology has followed a predictable pattern in the treatment of aortic aneurysm disease. Initially, endovascular aneurysm repair (EVAR) was used to treat infrarenal abdominal aortic aneurysms (AAA) only in patients deemed medically unsuitable for open surgical repair (OSR). With improvement in device design, increased operative experience and favorable mortality benefits in randomized control trials, EVAR is now the preferred method for treatment of AAA worldwide. As the results with OSR are even worse as one ascends the aorta into the visceral segment and above, it stands to reason that EVAR technology to accommodate the aortic branches should have a similar adoption in treatment of proximal AAA and thoraco-abdominal aortic aneurysm (TAAA) disease. The first devices trialed and approved for treatment of the visceral aorta are custom manufactured and have had excellent results in complex pathology. However, there are several temporal, engineering and anatomic limitations to custom, manufactured branched and fenestrated endografts. Surgeon modified endovascular aneurysm repair (SM-EVAR) is able to overcome many of these constraints and expands this technology to more patients with excellent short term results in select centers.

Abstract
Brachial artery pseudoaneurysms secondary to intravenous drug abuse represent a limb-threatening problem to patients and a technical challenge to the vascular surgeon. Here information is reported about a patient with metachronous bilateral giant brachial artery pseudoaneurysms secondary to intravenous drug use that were successfully treated with excision of the aneurysm and ligation of the brachial artery. Furthermore, a review of the current literature on the treatment of brachial artery aneurysm is presented.

Abstract
Open repair of abdominal aortic aneurysms (AAAs) or occlusive disease can be complicated by pseudoaneurysm formation and aneurysmal dilatation of native vessels. Reports of reoperation for these new lesions have a mortality rate of 5–17% electively, and 24–88% if ruptured. These complications are commonly several years after initial repair, and progression of other comorbidities can further complicate a repeat exploration. The authors reviewed 5 cases of late complications of open aortic bypass surgery treated with endovascular stent grafting as an alternative to reexploration in patients with increased risk for morbidity and mortality. Over a 6-year experience, 5 patients underwent endovascular stent grafting to repair paraanastomotic aneurysms. Patient records were reviewed and clinical cardiac risk evaluation was performed. Follow-up clinic notes and computed tomography (CT) scans were evaluated. Between October 1996 and February 2002, 5 patients underwent 6 endovascular procedures to repair paraanastomotic aneurysms. Mean period between interventions was 16.6 ±6.27 years (range 10–25); mean age at endovascular procedure 74.2 ±6.37 years (range 67–84). Cardiac clinical risk index increased in 80% of patients by Goldman Risk Index and in 40% by the Modified Cardiac Risk Index. On completion angiography, there was complete exclusion of the paraanastomotic aneurysms in all cases (100%). Length of postoperative stay was 1.5 ±0.547 days. Mean estimated blood loss at conclusion of endovascular procedure was 577 ±546.504 cc (range, 60 cc–1,500 cc). Mean follow-up was 24.4 ±24.593 months (range, 5–67 months). On repeat imaging, all stent grafts remain patent without rupture or endoleak. Endovascular stent grafting to repair late complications of open AAA repair is a viable alternative to reexploration in patients with significant comorbidities. These procedures can be performed without violating the previous surgical planes of sites. The operations can be performed under local anesthesia and with reduced hospitalizations. In patients with increased risk factors, endovascular stent grafting is a less morbid alternative to open surgical techniques.

Abstract
OBJECTIVE Patients with vascular disease often have multisystem atherosclerosis and multiple comorbidities requiring comprehensive interdisciplinary specialty care. Consultation is a critical component of a tertiary vascular surgery practice, but analysis of this service is under-reported in the literature. After-hours inpatient consultations and interhospital transfers are associated with urgent patient care. METHODS A retrospective analysis of vascular surgery consultations was carried out from January 1, 2013, to December 31, 2013. Consultations included inpatient services, the emergency department, surgical and medical intensive care unit, and interhospital transfers. Data analysis included number of consults, time of consultation (during hours, 0700-1859; after hours, 1900-0659), referring service, nature, and outcome of consultation. Consultations were then classified as urgent if vascular surgical intervention was required as an intraoperative consultation, within 24 hours, or during the same hospitalization. Patients without a same-hospital vascular surgical intervention were classified as nonurgent. RESULTS During a 1-year period, 823 independent consult requests of 749 patients were analyzed. It was found that 57.8% of after-hours consults resulted in urgent patient care (P = .003); 29.7% of medicine, 33.3% of medical intensive care unit, 41.9% of trauma surgery, and 60% of emergency department after-hours consultations were urgent; 73% of surgery and 79.2% of interhospital after-hours consults required urgent vascular surgical intervention. Extremity ischemia, aortic disease, and iatrogenic consults accounted for 44.8%, 20.4%, and 11.1% of after-hours consults, with 57.9%, 56.4%, and 70% requiring urgent vascular surgical intervention, respectively. CONCLUSIONS After-hours consultations are not always associated with an urgent vascular surgical intervention. Nonurgent after-hours consultations are requested more frequently from some services and may present an opportunity for education that could improve workflow of the vascular workforce.

Abstract
OBJECTIVE Readmission rates after vascular surgery are among the highest within surgical specialties, and lower extremity bypass has the highest readmission rate of vascular surgery procedures. We analyzed how 30-day readmissions and risk factors for readmissions vary by indication for lower extremity bypass. METHODS We queried the 2012-2014 American College of Surgeons National Surgical Quality Improvement Program procedure-targeted vascular cohort to identify all patients who underwent lower extremity bypass. Emergent procedures and planned readmissions were excluded. Patients were stratified by surgical indication: claudication, critical limb ischemia rest pain (CLI RP), critical limb ischemia tissue loss (CLI TL), and other. The χ2 and Wilcoxon rank sum tests were used to test the differences between categorical and continuous variables, respectively. Logistic regression was used to estimate odds ratios for predictors of readmission adjusted for preoperative factors that were selected a priori. RESULTS The overall 30-day readmission rate among the 6112 patients who underwent lower extremity bypass was 14.8%. Readmission rates varied significantly on the basis of the indication for surgery. In unadjusted comparisons, 18.8% of patients with CLI TL were readmitted compared with 16.5% with CLI RP, 9.4% with claudication, and 8.2% with other indications (P < .001). After adjustment for preoperative factors, 30-day readmissions were higher for patients with CLI TL (odds ratio, 1.67; 95% confidence interval, 1.35-2.06) and CLI RP (odds ratio, 1.70; 95% confidence interval, 1.38-2.09) compared with patients with claudication. CONCLUSIONS The 30-day readmission rates after lower extremity bypass vary significantly by surgical indication. Because lower extremity bypasses are performed for multiple indications, if readmission rates are publically reported and hospitals can be penalized for higher than expected readmission rates, the expected readmission rates should be adjusted for surgical indication.
