Abstract Objective: To study the safety and effect of endovascular therapy of long-segment total occlusion of superficial femoral artery using femoropopliteal artery dual input technique. Materials and Methods: Fifteen patients were treated with endovascular therapy of long-segment total occlusion of superficial femoral artery using femoropopliteal artery dual input technique. CTA examination of lower limb were performed for all patients which can be evaluated the length of occlusion segment and distal outflow tract. All patients underwent retrograde popliteal artery puncture and the balloon angioplasty and the stent implantation were performed in all cases. The ankle/braehial index(ABI) and symptoms post-treatment and pre-treatment were analyzed. Ankle-brachial index and Doppler ultrasound of lower extremity arteries were peformed every 3 months after endovascular therapy. Results: Fifteen cases with long-segment total occlusion of superficial femoral artery were recallalized, with technical success rate of 100%. The symptoms of rest pain disappeared in 14 cases． The ABI was 0.68±0.088 for post-treatment and 0.36±0.12 for pre-treatment respectively(t=18．62, P<0.01)． During 2～16 months’ follow up, 1 case of foot ulcers has not been controled, undergoing amputation 2 months after interventional treatment; 1 case recurrence of rest pain 3 months after therapy, Doppler ultrasound showing femoral artery stent restenosis, which was treated successfully once again after balloon angioplasty. The remaining patients with no recurrence. Conclusion: It is safe and effective to apply femoral artery combined with popliteal artery puncture technique to treat long-segment total occlusion of superficial femoral artery. It is a new idea for interventional treatment of lower extremity arterial occlusion.
