This study states that Despite endovascular advancements, aortofemoral bypass (AFB; aortounifemoral and aortobifemoral bypass) remains the most durable option for aortoiliac occlusive disease. Whereas AFB reduces vascular aortoiliac reintervention, the impact of laparotomy-associated and groin wound complications on morbidity and reintervention is unclear. The aim of this study was to establish the incidence of nonvascular complications after AFB and to determine their effect on reintervention. Institutional data for AFB (2000-2017) were queried. Primary end points included laparotomy-associated and groin wound complications. Total reintervention was defined as the composite outcome of reinterventions for laparotomy and groin wound complications and graft patency. Kaplan-Meier analysis estimated freedom from reintervention. Fine-Gray method for competing long-term risk determined predictors of laparotomy complications. Logistic regression, adjusting variability for patient-level clustering, determined predictors of wound complications.

There were 553 limbs in 281 patients (272 aortobifemoral and 9 aortounifemoral bypasses; age, 67.6 ± 11.0 years; 50.5% female).
