Different strategies exist in the treatment of chronic long occlusion of the superficial femoral artery. Traditionally, these patients should be treated with bypass. If the great saphenous vein is unavailable, doctor has to choose artificial vessel as graft. Now, the skill of endovascular treatment is developing rapidly, and lots of doctors think most of such patients could be treated with stent. The purpose of this trial is to compare stent and artificial blood vessel bypass in the treatment of long occlusion of the superficial femoral artery. The study hypothesis is that patency rates are comparable and therefore the minimal invasive treatment of stent can be considered in such patients.
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.

We describe a case of an infected popliteal artery stent with septic emboli presenting 6 years after peripheral vascular intervention for intermittent claudication. Management included resection of th...
Endovascular salvage of failed surgical bypasses has been scantly reported for treatment of infrainguinal occlusive disease. While catheter-directed thrombolysis and/or mechanical thromboembolectomy h...
Angiosarcoma is an exceedingly rare and aggressive neoplasm. Due to early metastasis even in low-grade tumors, it is associated with poor survival. We report a late development of an angiosarcoma in a...
As opposed to an endoluminal stent-graft, a multilayer stent (MS) consists of a porous mesh, which allows for the possibility of treating pararenal aortic aneurysms (PRAAs) that involve a significant ...
Previous studies have indicated that stent implantation could alter the vessel geometry, which may impact the neointimal healing process. Curvature is an important parameter for evaluating vessel geom...
Surgical construction of an artificial opening (stoma) for external fistulization of a duct or vessel by insertion of a tube with or without a supportive stent.
The continuation of the femoral artery coursing through the popliteal fossa; it divides into the anterior and posterior tibial arteries.
The vein formed by the union of the anterior and posterior tibial veins; it courses through the popliteal space and becomes the femoral vein.
The vein accompanying the femoral artery in the same sheath; it is a continuation of the popliteal vein and becomes the external iliac vein.
Diversion of the flow of blood from the entrance of the right atrium directly to the aorta (or femoral artery) via an oxygenator thus bypassing both the heart and lungs.
A stent is a small mesh tube that's used to treat narrow or weak arteries. Arteries are blood vessels that carry blood away from your heart to other parts of your body. A stent is placed in an artery as part of a procedure called angioplasty. &...
