Patients presenting with long occlusion of the superficial femoral artery enrolled in bypass arm will undergo suprageniculate femoropopliteal bypass surgery to bypass the occluded superficial femoral artery. And the graft will be artificial blood vessel.
Device: femoral-popliteal bypass with artificial blood vessel
Before operation, take aspirin 100mg every day. Groin and suprageniculate incision, PTFE graft with end to side anastomoses.
Before operation, take aspirin 100mg every day. During the operation, stent is delivered by a catheter and positioned through the narrowing in the artery. The stent is then expanded against the wall of the blood vessel to provide a wider channel for blood. At last, use balloon dilate the stent.
This is a multi-center, prospective, randomized, controlled trial to compare the therapeutic effect of stent and artificial blood vessel bypass to chronic long occlusion of the superficial femoral artery. Totally 200 patients will be entered into the trial. The study population will consist of patients with long superficial femoral stenosis and occlusion lesion (≥15 cm), presenting symptomatic ischemia（Rutherford 3-6）. The lesion does not extend beyond the aortoiliac artery or blow-knee popliteal artery, with at least 1 vessel infra-popliteal runoff to the foot.
Trial participants will be randomized to either stent group or artificial blood vessel bypass group.
Patients will be followed up for 3 years. Study examinations will be done at screening, procedure time, 1, 6, 12, 24 and 36 months after procedure.
This study will be conducted at 3 centers in Beijing, China.
