Purpose: To compare outcomes between open (OR) and endovascular repair following superficial femoral artery (SFA) injuries.
Methods: This is a cross-sectional study querying the 2012-2014 National Inpatient Sample for SFA injuries. Patients were grouped into OR and stent-graft placement (SGP). Primary outcome was in-hospital mortality. Secondary outcomes included hospital length of stay (HLOS), fasciotomy and amputation rate, and cost. Wilcoxon rank-sum, Kruskal-Wallis, Chi-squared test with Bonferroni adjustment were used as appropriate; p < 0.05 was significant.
Results: 255 Patients were identified. Mean age was 34.6 years and majority were males. OR was performed in 82.7%. Overall mortality rate was 3.7%. Median HLOS was 8 days. Fasciotomies were performed in 31% and lower limb amputations in 3.7%. Males more often underwent OR (89.0% vs. 73.1%, p < 0.01). SGP patients were significantly older (44.9 vs. 32.5 years; p < 0.01), and with Medicare insurance (20.5% vs. 6.5%; p < 0.01. Mortality, HLOS, and hospitalization cost were not significantly different. OR patients had higher rate of fasciotomy (35.4% vs. 15.4%; p < 0.01).
Conclusions: Endovascular management is not inferior to OR following SFA injuries and both carry a low amputation rate. OR is associated with a higher fasciotomy rate. Endovascular repair should be considered when technically feasible.

Background And Objectives: The key points of a monographic vascular access (VA) consultation are an adequate preoperative assessment, as well as a correct management and optimization of waiting lists. Our main objective of present study was to evaluate the degree of exploratory-dependent concordance in outpatient clinics regarding implanted VA, between nephrology and vascular surgery.
Materials And Methods: We analyzed VA created or surgically repaired between 2021 and 2022.

Objectives: This study assessed the association between chronic obstructive pulmonary disease (COPD) severity and postoperative mortality among patients undergoing thoracic endovascular aortic repair (TEVAR) and complex endovascular aortic repair (CEVAR).
Methods: A retrospective review of the Vascular Quality Initiative database identified elective TEVAR and CEVAR cases from 2013-2022 with endograft proximal landing zone ≥2 for thoracic or complex abdominal aortic disease. Symptomatic disease, ruptures, and urgent/emergent surgeries were excluded.

Objective: Frailty has become an increasingly recognized perioperative risk stratification tool. While frailty has been strongly correlated with worsening surgical outcomes, the individual determinants of frailty have rarely been investigated in the setting of aortic disease. The aim of this study was to examine the determinants of an 11-factor modified frailty index (mFI-11) on mortality and postoperative complications in patients undergoing endovascular aortic aneurysm repair (EVAR).

Objectives: Optimal timing for intervention for abdominal aortic aneurysms remains unclear. Given the increased rupture risk with larger aneurysms, timely intervention is critical. This study sought to examine endovascular aortic aneurysm repairs (EVAR) delays across Canadian centers, focusing on potential differences related to geography, sex and race.

Background: Thoracic Endovascular Aortic Repair (TEVAR) reduced mortality for blunt aortic injury (BAI) from 30-50% to < 10%; however, penetrating traumatic aortic injury (PAI) remains highly lethal (>40% mortality). This study's goal is to determine outcomes of TEVAR for PAI.
Methods: Patients undergoing TEVAR for traumatic aortic injuries were identified from the Vascular Quality Initiative database from 2011-2022.
