Abstract

Background: No adequately powered studies exist to compare major clinical outcomes after endovascular therapy (EVT) with stent implantation vs bypass surgery (BSx) for symptomatic femoropopliteal peripheral artery disease. Objectives: This study sought to perform a pooled analysis of individual patient data from all randomized controlled trials comparing EVT vs BSx. Methods: Principal investigators of 5 of 6 available randomized controlled trials agreed to pool individual patient data. The primary endpoint was major adverse limb events, a composite of all-cause death, major amputation, or target limb reintervention. Secondary endpoints included amputation-free survival, individual major adverse limb event components, and primary patency. Early complications were bleeding, infection, or all-cause death within 30 days. Results: A total of 639 patients were analyzed with a mean age of 68.1 ± 9.1 years and 29.0% women. Baseline characteristics were comparable between groups. At 2 years, there were no significant differences between patients who received EVT and those who received BSx regarding major adverse limb events (40.1% vs 36.4%; log-rank P = 0.447; adjusted HR [aHR]: 1.04; 95% CI: 0.80-1.36), amputation-free survival (88.1% vs 90.0%; log-rank P = 0.455; aHR for death or amputation: 1.04; 95% CI: 0.63-1.71) and the other secondary endpoints except for primary patency, which was lower in patients who received EVT vs those who received BSx (51.2% vs 61.3%; log-rank P = 0.024; aHR for loss of primary patency: 1.31; 95% CI: 1.02-1.69). EVT was associated with significantly lower rates of early complications (6.8% vs 22.6%; P < 0.001) and shorter hospital stay (3.1 ± 4.2 days vs 7.4 ± 4.9 days; P < 0.001). Conclusions: These findings further support the efficacy and safety of EVT as an alternative to BSx in patients with symptomatic femoropopliteal peripheral artery disease.
