    ABSTRACT: Recent reports have shown promising early results after endovascular revascularization (percutaneous transluminal angioplasty [PTA]/stent) of patients with peroneal artery-only runoff (PAOR), although the long-term durability is unclear. This study evaluated long-term primary patency and limb salvage of PTA/stent in patients with single-vessel runoff and critical limb ischemia to determine if the peroneal artery yields inferior results. From January 2002 to December 2007, 1075 infrainguinal PTA/stent procedures were performed in 920 patients. The study cohort comprised 201 limbs in 187 patients with single-vessel runoff and critical limb ischemia. End points included primary patency, assisted patency, limb salvage, and survival. Long-term outcomes were determined by Kaplan-Meier life-table and multivariate Cox regression analyses. There were 104 PAOR and 97 limbs with single-vessel posterior or anterior tibial artery runoff (non-PAOR). Median follow-up was 25 months (range, 0-75 months). PAOR patients tended to be older (77.36 ± 0.92 vs 72.65 ± 1.18 years, P = .002) and were more likely to be taking clopidogrel at presentation (88% vs 76%; P = .04). There were no statistically significant differences in 5-year primary patency (26% ± 6.8% vs 30% ± 7.6%; P = .79), assisted patency (75% ± 8.8% vs 81% ± 7.0%; P = .77), limb salvage (74% ± 8.0% vs 75% ± 7.1%; P = .47), and survival (38% ± 7.7% vs 47% ± 6.6%; P = .99) between the PAOR and the non-PAOR groups, respectively. On Cox regression multivariate analysis, total occlusions predicted decreased assisted patency (hazard ratio, 2.99; 95% confidence interval, 1.21-7.41; P = .02), whereas younger age predicted poor limb salvage (hazard ratio, 0.97; 95% confidence interval, 0.94-0.99; P = .04). PAOR was not an independent predictor of any outcome on multivariate analysis. Patients with PAOR have similar long-term outcomes to patients with non-PAOR. Thus, infrainguinal endovascular revascularization can be considered a first-line therapy for patients with PAOR and critical limb ischemia.
