OBJECTIVE: To evaluate the efficacy of infra-inguinal, primary angioplasty as a method of limb salvage in patients with trophic lesions secondary to critical ischemia. MATERIALS AND METHODS: Thirty-six patients submitted to primary percutaneous transluminal angioplasty without stenting were evaluated. All of them presented critical limb ischemia with trophic lesion (Rutherford grade III, category 5). Eighty-four angioplasties were performed for 17 lesions in superficial femoral artery, 16 lesions in popliteal artery, and 51 lesions in below-knee arteries. Additionally, prevalence in relation to sex, age, limb involved and main comorbidities have been discussed, with technical considerations regarding procedures and materials utilized. RESULTS: Clinical success has been defined as complete healing of the trophic lesion or amputation level limited to toes or forefoot, not requiring bypass surgery, independently from time, drugs utilized and number of debridement procedures performed. CONCLUSION: Femoropopliteal and belowknee angioplasties present high technical success, low mortality and low complications rates and are highly effective in the treatment of patients with critical lower limb ischemia.
