Abstract Objective: To evaluate the clinical effectiveness after stenting of superficial femoral artery(SFA) obliterans in 3-year follow-up, and to evaluate the relevant factors affecting therapeutic effect. Methods: Seventy-nine patients were diagnosed as superficial femoral artery obliterans and received stent placement from January 2010 to December 2012 in the interventional department, Shengjing Hospital. The clinical data after stenting were retrospectively analyzed. All the patients suffered with different degrees of lower extremity ischemic symptoms. The criteria for observation was primary patency with limb save at 6th, 12th, 24th, and 36th months after stent placement and the restenosis rate. The multiple factor analysis of the survival and effective rate was performed. Results: All the 79 patients received balloon expanding with stent placement and postoperative angiography showed 100% technical success. All the patients received Rutherford classification with the preoperative average score of 3.60±0.89, and postoperative score of 1.41±1.18 at 36th month, there was statistical significance difference. The recurrence of ischemic symptoms was seen in 27 limbs within one month to 3 years after treatment. No recurrence, only in 8 patients who did not have good control of diabetes and 10 still continued smoking. Conclusion: Endovascular treatment with stent plantation for 79 cases of superficial femoral artery obliterans was effective and safe at postoperative within 3 years. The result of primary patency had statistical significance between the length of the occluded SFA segment(5~15 cm) and (>15 cm). Effective control of diabetes and smoking, are the main factors which affect therapeutic results.
