Objective: We assessed early and late outcomes following hybrid intervention (common femoral artery endarterectomy and superficial femoral artery (SFA) stenting) versus above-the-knee (AK) femoro-popliteal bypass performed for peripheral artery occlusive disease (PAOD) in a double-center retrospective comparative cohort study. Materials and methods: From January 2006 to December 2017, 82 hybrid revascularizations with femoral endarterectomy and SFA stenting (HY Group) and 98 AK femoro-popliteal bypasses with femoral endarterectomy (BP Group) were performed at two academic vascular centers. The two groups were compared in terms of preoperative and intraoperative details and of perioperative (<30 days) outcomes with χ2 test. Long-term results were compared using Kaplan-Meier curves and log-rank test. Results: No differences were found in demographics variables, risk factors, comorbidities and clinical presentation between the two groups. Also perioperative outcomes were similar between the two groups. Median duration of follow-up was 38 months. At five years, the estimated survival rate was 60% in HY Group and 77.5% in BP Group (p = 0.002) Five-year primary patency rates were 46% in HY Group and 64% in BP Group (p = 0.005). Overall, 13 patients in HY Group required conversion to open surgery and 6 patients in BP Group underwent below-knee (n = 4) or distal (n = 2) bypass. The 5-year rate of limb maintenance was 85% in HY Group and 94% in BP Group (p = 0.1) and was not significantly different regardless of presentation, claudication or critical limb ischemia. Conclusions: In patients with PAOD due to complex long lesions of the infrainguinal arteries, open-surgical treatment with AK bypass provided better long-term survival and patency rates compared to a hybrid approach.

Abstract

Objective: We assessed early and late outcomes following hybrid intervention (common femoral artery endarterectomy and superficial femoral artery (SFA) stenting) versus above-the-knee (AK) femoro-popliteal bypass performed for peripheral artery occlusive disease (PAOD) in a double-center retrospective comparative cohort study. Materials and methods: From January 2006 to December 2017, 82 hybrid revascularizations with femoral endarterectomy and SFA stenting (HY Group) and 98 AK femoro-popliteal bypasses with femoral endarterectomy (BP Group) were performed at two academic vascular centers. The two groups were compared in terms of preoperative and intraoperative details and of perioperative (<30 days) outcomes with χ2 test. Long-term results were compared using Kaplan-Meier curves and log-rank test. Results: No differences were found in demographics variables, risk factors, comorbidities and clinical presentation between the two groups. Also perioperative outcomes were similar between the two groups. Median duration of follow-up was 38 months. At five years, the estimated survival rate was 60% in HY Group and 77.5% in BP Group (p = 0.002) Five-year primary patency rates were 46% in HY Group and 64% in BP Group (p = 0.005). Overall, 13 patients in HY Group required conversion to open surgery and 6 patients in BP Group underwent below-knee (n = 4) or distal (n = 2) bypass. The 5-year rate of limb maintenance was 85% in HY Group and 94% in BP Group (p = 0.1) and was not significantly different regardless of presentation, claudication or critical limb ischemia. Conclusions: In patients with PAOD due to complex long lesions of the infrainguinal arteries, open-surgical treatment with AK bypass provided better long-term survival and patency rates compared to a hybrid approach.
