    Abstract:
    INTRODUCTION: The purpose of the study was to evaluate the efficacy and safety of the "percutaneous direct puncture of occluded superficial femoral artery (SFA)" technique for recanalization of SFA, after failure of antegrade recanalization in patients with limited access to retrograde popliteal and crural arteries. MATERIAL AND METHODS: Between April 2014 and November 2017, 10 patients with CLI (Critical limb ischemia) underwent endovascular recanalization with direct percutaneous puncture of occluded SFA after failed antegrade recanalization. All patients had a long segment (39,9 ± 2.8 cm) occluded SFA without stump causing failed antegrade recanalization with a cannulated guidewire in the SFA origin. After unsuccessful attempts with the antegrade approach, the retrograde direct puncture technique of the occluded SFA was performed and followed by antegrade recanalization. Patients were followed up clinically with Doppler ultrasonography and according to the Rutherford scale at 1, 3, 6 and 12 months after discharge. RESULTS: Technical success was achieved in 8/10 patients (80%).The mean follow-up period was 25,1 ± 9,6 months. One patient underwent major amputation, resulting in 90% limb salvage rate at 12 and 24 months. Amputation-free survival estimated by Kaplan-Meier analysis was 60% at 12 and 24 months. Primary patency rates were 62.5% at 12 and 24 months and secondary patency rates were 87.5% at 12 and 24 months. CONCLUSION: Treatment of SFA occlusions without a stump in CLI patients via the percutaneous direct puncture of occluded SFA approach improved technical success and clinical recovery, especially in cases unsuitable for conventional antegrade and retrograde approaches.
