OBJECTIVE: Peroneal artery bypass is effective for limb salvage (LS), however, the efficacy of peroneal artery-only runoff (PAOR) following endovascular (EV) interventions is unknown. The goal of our article was to compare the efficacy of EV interventions with PAOR to those with other runoff vessels for LS in patients presenting with tissue loss. METHODS: A retrospective review of 111 consecutive patients who underwent infrainguinal EV revascularizations for nonhealing ulcers/gangrene between June 2001 and December 2006 was performed. Patients with PAOR (n = 33) were compared with those with other vessel runoff (OTHER, n = 78). Fisher exact test and chi2 test were used for comparing variables, Kaplan-Meier analyses for patency, LS, and Cox regression multivariate analysis was used for identifying factors associated with limb loss. RESULTS: The patients in PAOR were older, but other morbidities were similar between groups. The most distal level of intervention was infrapopliteal (tibioperoneal or peroneal artery) in 42% in PAOR group whereas this was 24% in OTHER group (P = .071). Preoperative ankle-brachial index (ABI) was similar (0.49 +/- 0.23 vs 0.50 +/- 0.23), however, postprocedure ABI was significantly less for patients with PAOR (0.76 +/- 0.21 vs 0.92 +/- 0.13, P = .001). The primary patency, assisted primary patency, secondary patency and LS were not significantly different between groups. There was also no difference in time-to healing between groups (PAOR vs OTHER, 2.9 +/- 2.1 mo vs 3.7 +/- 3.6 mo, P = .319). We found the presence of gangrene (odds ratio [OR]: 3.5, 95% confidence interval [CI], 1.1-10.8, P = .028) and dialysis-dependence (OR: 2.9, 95% CI, 1.0-8.2, P = .046) to be associated with limb loss, when adjusted for diabetes, hypertension, hyperlipidemia, smoking, location of wound, and PAOR. CONCLUSION: Endovascular revascularization with PAOR results in acceptable patency and limb salvage rates in patients presenting with tissue loss, and is equivalent to other vessel runoff for patency, limb salvage and wound healing rates.
