Raison d’etre of Tibial Artery Bypass for Intermittent Claudication in the Era of Endovascular Therapy

Background:There is currently no positive opinion regarding infrapopliteal revascularization for intermittent claudication (IC) in any guidelines. The aim of this study was to analyze the outcomes of infragenicular bypass and verify the adequacy of tibial artery bypass for IC.Methods and Results:Over a 21-year period, 58 below-knee popliteal artery (BKPOP) bypasses and 35 tibial artery bypasses were performed for IC caused by arteriosclerosis obliterans. Graft patency and major amputation (MA) were examined as primary endpoints and the predictor of each outcome was estimated by multivariate analysis. The primary patency (PP), secondary patency (SP), and freedom from MA (ffMA) rates of a prosthetic/vein graft in all cases at 5 years were 19/68%, 22/86%, and 78/100% (P
