Objective The purpose of this study is to determine whether the TransAtlantic InterSociety Consensus (TASC) criteria (Ⅱ-2007 versions), the Society of Vascular Surgery (SVS) runoff score or risk factors for peripheral arterial disease were correlated with postoperative outcome of superficial femoral artery occlusive disease. Methods From January 2006 to September 2009, patients who suffered from lower extremity atherosclerosis occlusion disease and underwent endovascular or surgical therapy in superficial femoral artery segment were reviewed retrospectively at Beijing Tongren Hospital. Femoralpopliteal artery lesions were graded according to the TASC Ⅱ criteria. Runoff scores were determined in infrapopliteal artery segment lesions. All patients were followed up. Kaplan-Meier method was applied to calculate primary patency rate, and COX regression analysis was used to determine if TASC Ⅱ classification,runoff score, or factors for peripheral arterial disease affected primary patency rate. Results 142 patients (197 limbs) were followed up after treatment at 1 month, 3 months, 6 months, and every 6 months thereafter. Median follow-up time was 13 months. By Cox regression analysis, TASC Ⅱ classification(RR =1.471,P = 0. 012 ), runoff score ( RR = 1.190, P = 0. 004 ), and type 2 diabetic mellitus ( RR = 2. 320, P =0.019) significantly affected primary patency. Conclusions Postoperative poor patency rates are associated with higher degree of the TASC Ⅱ lesions, poor initial runoff score, and type 2 diabetic mellitus in patients of superfical femoral artery occlusive disease.
