ABSTRACT

OBJECTIVES: This study was performed to study the outcomes of operations in the patients with atherosclerosis obliterans of lower extremities. METHODS: Forty patients underwent vascular bypass operations from January 2006 to December 2010 and were analyzed retrospectively with clinical records. RESULTS: Forty six bypassing procedures were performed in 40 limbs. The type of operations were femoro-popliteal bypass in 29 limbs, femoro-femoral bypass in 15 patiens and popliteo-posterior tibial bypass in 2 limbs. Forty three procedure were done with polytetrafluoroethylene(PTFE) graft and 3 were done with great saphenous vein. The cumulative patency rates of 5years was 58.9% respectively. In two patients, amputations of the lower extremities were done. Reoperations were performed in 9 patients. CONCLUSIONS: A thoughtful management can prevent the progress of atherosclerosis obliterans(ASO) and may preserve the function of lower limb. In this study, bypass surgery using PTFE and great saphenous vein as conduit revealed acceptable patency rate.
