Effectiveness and Safety of Atherectomy versus Plain Balloon Angioplasty for Limb Salvage in Tibioperoneal Arterial Disease

Abstract

PurposeTo evaluate the effectiveness and safety of atherectomy versus plain balloon angioplasty (POBA) for treatment of critical limb ischemia (CLI) due to tibioperoneal arterial disease (TPAD). Materials and MethodsPatients enrolled in the Vascular Quality Initiative registry who had CLI (Rutherford Class 4–6) and underwent atherectomy versus POBA alone for isolated TPAD were retrospectively identified. Of eligible patients, a cohort of 2,908 patients was propensity matched 1:1 by clinical and angiographic characteristics. The atherectomy group comprised 1,454 patients with 2,183 arteries treated, and the POBA group comprised 1,454 patients with 2,141 arteries treated. The primary study endpoint was major ipsilateral limb amputation. Secondary endpoints were minor ipsilateral amputations, any ipsilateral amputation, primary patency, target vessel reintervention (TVR), and wound healing at 12 months. ResultsThe median follow-up period was 507 days, the mean patient age was 69 years ± 11.7, and the mean occluded length was 6.9 cm ± 6.5. There was a trend toward higher technical success rates with atherectomy than with POBA (92.9% vs 91.0%, respectively; P = .06). The rates of major adverse events during the procedure were not significantly different. The 12-month major amputation rate was similar in the atherectomy and POBA groups (4.5% vs 4.6%, respectively; P = .92; odds ratio, 0.97; 95% CI, 0.68–1.37). There was no difference in 12-month TVR (17.9% vs 17.8%; P = .97) or primary patency (56.4% vs 54.5%; P = .64) between the atherectomy and POBA groups. ConclusionsIn a large national registry, treatment of CLI from TPAD using atherectomy versus POBA showed no significant differences in procedural adverse events, major amputations, TVR, or vessel patency at 12 months.
