RESUMEN
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.

OBJECTIVE: The 2010 Pacific Vascular Symposium 6 (PVS6) brought venous disease content experts together with a goal of addressing critical issues collated together in the next decade with concrete plans to achieve these goals. This mapping review aims to provide a broader representation of how progress in critical issues of chronic venous disease has been made by extrapolating scientific publications related to the PVS6 initiatives. METHODS: We performed a mapping review identifying original or systematic review/meta-analysis articles related to PVS 6 initiatives (aims) that addressed one of the following key objectives: scales to measure chronic venous disease, effectiveness of interventional deep venous thrombus removal, development of a deep venous valve, and biomarkers related to venous disease. Searches were undertaken in PubMed, Ovid Medline, Cochrane Library, Embase (Elsevier), CINAHL (EBSCO), and Scopus. We extracted descriptive information about the studies and predefined variables for each specific aim, showing what and where research exists on the aims included. RESULTS: A total of 2138 articles were screened from 3379 retrieved articles from six electronic databases. We mapped 186 included articles, finding that the total number of publications significantly increased after the 2010 PVS6 meeting. Aim results were visually summarized. The largest body of data addressed catheter-based thrombus removal strategies for acute iliofemoral deep venous thrombosis. Primary research on artificial venous valves and venous biomarkers remained limited. No new post-thrombotic syndrome (PTS) score has been developed. CONCLUSIONS: This mapping review identified and characterized the available evidence and gaps in our knowledge of chronic venous disease that exist visually, which may guide where more significant investments for the future should be targeted.

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

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.

OBJECTIVE: Aberrant subclavian artery (ASA) and Kommerell's diverticulum (KD) are rare vascular anomalies that may be associated with lifestyle-limiting and life-threatening complications. The aim of this study is to report contemporary outcomes after invasive treatment of ASA/KD using a large international dataset. METHODS: Patients who underwent treatment for ASA/KD (2000-2020) were identified through the Vascular Low Frequency Disease Consortium, a multi-institutional collaboration to investigate uncommon vascular disorders. We report the early and mid-term clinical outcomes including stroke and mortality, technical success, and other operative outcomes including reintervention rates, patency, and endoleak. RESULTS: Overall, 285 patients were identified during the study period. The mean patient age was 57 years; 47% were female and 68% presented with symptoms. A right-sided arch was present in 23%. The mean KD diameter was 47.4 mm (range, 13.0-108.0 mm). The most common indication for treatment was symptoms (59%), followed by aneurysm size (38%). The most common symptom reported was dysphagia (44%). A ruptured KD was treated in 4.2% of cases, with a mean diameter of 43.9 mm (range, 18.0-100.0 mm). An open procedure was performed in 101 cases (36%); the most common approach was ASA ligation with subclavian transposition. An endovascular or hybrid approach was performed in 184 patients (64%); the most common approach was thoracic endograft and carotid-subclavian bypass. A staged operative strategy was employed more often than single setting repair (55% vs 45%). Compared with endovascular or hybrid approach, those in the open procedure group were more likely to be younger (49 years vs 61 years; P < .0001), female (64% vs 36%; P < .0001), and symptomatic (85% vs 59%; P < .0001). Complete or partial symptomatic relief at 1 year after intervention was 82.6%. There was no association between modality of treatment and symptom relief (open 87.2% vs endovascular or hybrid approach 78.9%; P = .13). After the intervention, 11 subclavian occlusions (4.5%) occurred; 3 were successfully thrombectomized resulting in a primary and secondary patency of 95% and 96%, respectively, at a median follow-up of 39 months. Among the 33 reinterventions (12%), the majority were performed for endoleak (36%), and more reinterventions occurred in the endovascular or hybrid approach than open procedure group (15% vs 6%; P = .02). The overall survival rate was 87.3% at a median follow-up of 41 months. The 30-day stroke and death rates were 4.2% and 4.9%, respectively. Urgent or emergent presentation was independently associated with increased risk of 30-day mortality (odds ratio [OR], 19.8; 95% confidence interval [CI], 3.3-116.6), overall mortality (OR, 3.6; 95% CI, 1.2-11.2) and intraoperative complications (OR, 8.3; 95% CI, 2.8-25.1). Females had a higher risk of reintervention (OR, 2.6; 95% CI, 1.0-6.5). At an aneurysm size of 44.4 mm, receiver operator characteristic curve analysis suggested that 60% of patients would have symptoms. CONCLUSIONS: Treatment of ASA/KD can be performed safely with low rates of mortality, stroke and reintervention and high rates of symptomatic relief, regardless of the repair strategy. Symptomatic and urgent operations were associated with worse outcomes in general, and female gender was associated with a higher likelihood of reintervention. Given the worse overall outcomes when symptomatic and the inherent risk of rupture, consideration of repair at 40 mm is reasonable in most patients. ASA/KD can be repaired in asymptomatic patients with excellent outcomes and young healthy patients may be considered better candidates for open approaches versus endovascular or hybrid modalities, given the lower likelihood of reintervention and lower early mortality rate.

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%â6.9% ± 4.4%, P < 0.001), which corresponded to a significant decrease in observed clinical myocardial infarction (MI) rate (4.1%â1.4%, 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%â7.2% ± 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%â0.3%, 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.

BACKGROUND: We investigated the clinical practice and volume trends of inferior vena cava filter (IVCF) usage at a single institution for an extended period and identified the potential factors affecting the clinical decision for placement, follow-up, and retrieval. METHODS: An institutional database was queried for IVCFs placed from 2000 to 2018 using the Current Procedural Terminology codes. The medical records were reviewed to evaluate the demographics, economic status, placement indication, IVCF type, follow-up evaluation for retrieval, and retrieval success rates. Statistical analysis was performed using SPSS, and t tests for continuous and χ2 for categorical variables. RESULTS: A total of 3915 IVCFs were placed from 2000 to 2018. The placement of IVCFs had increased steadily from 2000 (127 IVCFs/y), peaking in 2010 at 371 IVCFs/y and representing a 292% increase in IVCF usage. Since 2010, the number of IVCFs placed has steadily declined until 2016 to 2018, with a 426% decrease from the peak. In a subgroup of IVCFs placed for prophylaxis, the total volume trends paralleled a shift in clinical indications, peaking in 2010 and accounting for 45% of all IVCFs placed and then decreasing from 2013 to 2018 to ≤10%. Overall, 989 permanent IVCFs (25.3%) and 2926 retrievable IVCFs (74.7%) were placed during the entire study period. Before dedicated efforts to implement retrieval follow-up visits, the successful retrieval rate was â¼1% from 2000 to 2006 and had increased to â¼10% to 15% from 2007 to 2015, 36.7% in 2016, 40.2% in 2017, and 40.3% in 2018 after implementation of more active retrieval follow-up protocols. The predictors for the lack of evaluation for IVCF retrieval included an extended length of stay (P = .004) and geographic distance (P < .001). CONCLUSIONS: The use of IVCFs during the past 19 years at our institution reflected increased usage from 2000 to 2010, corresponding to an increase in prophylactic placement, followed by a decreasing total volume from 2011 to 2018, largely attributable to decreased prophylactic IVCF placement. Improved retrieval rates were seen after implementation of an active IVCF retrieval program.

BACKGROUND: 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 < 0.001), with survival being even greater among those receiving combined statin/AP therapy (12.2 ± 0.2 vs. 10.5 ± 0.4 years, Log Rank < 0.001). 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 < 0.001). 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 < 0.001, 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 < 0.001). 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 = 0 638). 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.

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.

A pseudoaneurysm of the proximal right brachial artery is rare, with most caused by penetrating or blunt trauma. We report the case of a 41-day-old patient with a large iatrogenic pseudoaneurysm of the right brachial artery that had been induced by a puncture lesion during peripherally inserted central catheter placement for treatment of Lennox-Gastaut syndrome. The patient was successfully treated with a multidisciplinary approach, that consisted of direct excision of the pseudoaneurysm, followed by microvascular direct anastomosis. The patient was discharged with no complications, and complete exclusion of the pseudoaneurysm was confirmed at the 2-year follow-up examination.
RESUMEN
As the importance of pelvic venous disorders (PeVD) has been increasingly recognized, progress in the field has been limited by the lack of a valid and reliable classification instrument. Misleading historical nomenclature, such as the May-Thurner, pelvic congestion, and nutcracker syndromes, often fails to recognize the interrelationship of many pelvic symptoms and their underlying pathophysiology. Based on a perceived need, the American Vein and Lymphatic Society convened an international, multidisciplinary panel charged with the development of a discriminative classification instrument for PeVD. This instrument, the Symptoms-Varices-Pathophysiology ("SVP") classification for PeVD, includes three domains-Symptoms (S), Varices (V), and Pathophysiology (P), with the pathophysiology domain encompassing the Anatomic (A), Hemodynamic (H), and Etiologic (E) features of the patient's disease. An individual patient's classification is designated as SVPA,H,E. For patients with pelvic origin lower extremity signs or symptoms, the SVP instrument is complementary to and should be used in conjunction with the Clinical-Etiologic-Anatomic-Physiologic (CEAP) classification. The SVP instrument accurately defines the diverse patient populations with PeVD, an important step in improving clinical decision making, developing disease-specific outcome measures and identifying homogenous patient populations for clinical trials.

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.

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.

OBJECTIVE: Carotid endarterectomy (CEA) with concomitant distal endovascular intervention (CEA+D) is infrequently necessary but has often been used as a salvage maneuver when complications occur during CEA. The present study aimed to determine whether preoperative risk factors associated with CEA requiring CEA+D exist and to evaluate the outcomes compared with isolated CEA. METHODS: The Vascular Quality Initiative CEA registry was used to identify patients who had undergone CEA or CEA+D for asymptomatic or symptomatic carotid stenosis from 2013 to 2019. Data regarding distal intervention included whether angioplasty or stenting of the distal internal carotid artery (ICA) and/or bifurcation had been required. However, information regarding the indication or whether the intervention had been planned was not included. The χ2 test and analysis of variance were used to evaluate the categorical and continuous perioperative variables. Variables with P < .20 on univariate analysis were included in the multivariable analysis to assess for preoperative predictors of the need for CEA+D and the association with perioperative stroke. RESULTS: From 2013 to 2019, 327 CEA+D cases were identified and compared with 105,192 isolated CEA cases. The CEA+D patients were more likely to have undergone previous ipsilateral CEA (CEA, 1.8%; CEA+D, 4.9%; P < .01) and contralateral ICA occlusion (CEA, 4.6%; CEA+D, 11.0%; P < .01) but were less likely to have had ipsilateral stenosis ≥70% (CEA, 88.3%; CEA+D, 80.6%; P < .01). The preoperative factors associated with the need for CEA+D on multivariable analysis included previous peripheral vascular intervention, American Society of Anesthesiologists class ≥4, contralateral ICA occlusion, low-volume surgeon, and previous ipsilateral CEA. CEA+D was associated with significantly increased rates of stroke in both asymptomatic (CEA+D, 3.9%; CEA, 0.9%; P < .01) and symptomatic (CEA+D, 9.4%; CEA, 1.9%; P < .01) patients. CEA+D was associated with decreased rates of 30-day survival in both asymptomatic (CEA+D, 98.3%; CEA, 99.4%; P = .02) and symptomatic (CEA+D, 94.8%; CEA, 99.1%; P < .01) cohorts. On multivariable analysis, CEA+D remained significantly associated with stroke (odds ratio, 3.17; 95% confidence interval, 1.80-5.60; P < .01). Other factors significantly associated with perioperative stroke included procedure length >135 minutes, diabetes, hypertension, shunt for indication, symptomatic status, previous ipsilateral CEA, contralateral ICA occlusion, urgent or emergent procedure, intravenous medications for hemodynamic instability, and re-exploration at the initial operation. CONCLUSIONS: Although markers of more significant cardiovascular disease burden were associated with the use of CEA+D, their power to predict CEA+D use was limited. In cases in which CEA+D was used, CEA+D was associated with significantly greater rates of perioperative stroke and mortality compared with isolated CEA for both asymptomatic and symptomatic patients, which could be useful for framing the expected outcomes after these procedures.

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.

OBJECTIVE: Surgical site infection (SSI) is an important complication of lower extremity bypass (LEB) and the rate of SSI after LEB varies widely in the existing literature, ranging from 4% to 31%. Prolonged length of stay (LOS) has been implicated in the occurrence of SSI across multiple surgical disciplines. The impact of preoperative LOS in patients with chronic limb-threatening ischemia (CLTI) undergoing LEB is unknown. We examined the association of preoperative LOS on SSI after LEB. METHODS: A retrospective analysis of the Society for Vascular Surgery Vascular Quality Initiative Infrainguinal Bypass Registry identified patients undergoing elective LEB for chronic limb-threatening ischemia from 2003 to 2019. Patients undergoing LEB for acute limb ischemia, urgent/emergent procedures, aneurysm, or who had concomitant suprainguinal bypass were excluded. The primary outcome measure was postoperative SSI. Multivariable forward stepwise logistic regression was then performed including all variables with a P value of less than .10 in both matched and unmatched cohorts to evaluate for demographic and perioperative predictors of SSI. Propensity score matching was used to create matched cohorts of patients for each LOS group. RESULTS: A total of 17,883 LEB procedures were selected for inclusion: 0 days (12,362 LEB), 1 to 2 days (1737 LEB), and 3 to 14 days (3784 LEB). Patients with the greatest preoperative LOS were more likely to have vein mapping (0 days preoperative LOS, 66.3%; 1-2 days, 65.2%; 3-14 days, 73.2%; P < .01) or computed tomography angiography/magnetic resonance angiography (0 days, 32.1%; 1-2 days, 34.4%; 3-14 days, 38.4%; P < .01). Patients with 3 or more days of preoperative LOS had longer procedure lengths (0 days, 244 minutes; 1-2 days, 243 minutes; 3-14 days, 255 minutes; P < .01) and were more likely to have completion angiogram (0 days, 27.1%; 1-2 days, 29.5%; 3-14 days, 31.6%; P = .02). Multivariable logistic regression demonstrated that preoperative LOS of 3 to 14 days was associated with increased rate of SSI (odds ratio [OR], 1.92; 95% confidence interval [CI], 1.20-3.07; P = .01). Transfusion of 3 or more units (OR, 2.87; 95% CI, 1.89-4.36; P < .01) and prolonged procedure length (>220 minutes; OR, 1.86; 95% CI, 1.26-2.73; P < .01) were also significantly associated with postoperative SSIs. CONCLUSIONS: Many factors including preoperative comorbidities and operative complexity covary with preoperative LOS as risk factors for SSI. However, when patients are matched based on comorbidities and factors that would predict overall clinical complexity, preoperative LOS remains important in predicting SSI.

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.

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.

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.
