Hybrid surgery for bilateral lower extremity inflow revascularization

AbstractObjectiveAortobifemoral (ABF) bypass is the preferred method of bilateral inflow revascularization, with axillobifemoral (AXBF) bypass reserved for high-risk patients. Hybrid (HYB) surgery in the form of femorofemoral bypass and retrograde endovascular aortoiliac intervention is increasingly being used to achieve the same goal. This study compared the perioperative outcomes of HYB surgery with traditional surgery for bilateral inflow revascularization. MethodsThe American College of Surgeons National Surgical Quality Improvement Program files for the years 2012 to 2015 were reviewed, and all patients undergoing ABF bypass, AXBF bypass, and HYB surgery (femoral-femoral bypass and retrograde endovascular intervention) were included. Patients' demographics, comorbidities, and outcomes were compared between the three groups. A propensity-matched analysis was subsequently performed to compare HYB surgery with ABF bypass only. The χ2 test and analysis of variance with post hoc analysis were conducted to evaluate between-group differences in risk factors and outcomes. SPSS statistical software (IBM Corp, Armonk, NY) was used. ResultsThere were 1426 patients (ABF bypass, 976; AXBF bypass, 257; HYB surgery, 193). There were significant differences in the three populations of patients, with ABF bypass patients significantly more likely to have age
