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.
