Background: Lesions in distal target arteries hinder surgical bypass procedures in patients with peripheral arterial occlusive disease.
Methods: Between April 2012 and October 2015, 16 patients (18 limbs) with lifestyle- limiting claudication (n=12) or chronic critical limb ischemia (n=6) underwent femoral?above-knee (AK) polytetrafluoroethylene (PTFE) bypass grafts with a bridging stent graft placement between the distal target popliteal artery and the PTFE graft. Ring-supported PTFE grafts were used in all patients with no available vein for graft material. Follow-up evaluations assessed clinical symptoms, the ankle-brachial index, ultrasonographic imaging and/or computed tomography angiography, the primary patency rate, and complications.
Results: All procedures were successful. The mean follow-up was 12.6 months (range, 11 to 14 months), and there were no major complications. The median baseline ankle-brachial index of 0.4 (range, 0.2 to 0.55) significantly increased to 0.8 (range, 0.5 to 1.0) at 12 months (p＜0.01). The primary patency rate at 12 months was 83.3%. The presenting symptoms resolved within 2 weeks.
Conclusion: In AK bypasses with a diffusely diseased distal target popliteal artery or when below-knee (BK) bypass surgery is impossible, this procedure could be clinically effective and safe when used as an alternative to femoral-BK bypass surgery.
