The consequences of a failed femoropopliteal bypass grafting: Comparison of saphenous vein and PTFE grafts

摘要: Objectives Although there are numerous reports comparing saphenous vein (SV) and polytetrafluoroethylene (PTFE) with respect to the patency rates for femoropopliteal bypass grafts, clinical consequences of failed grafts not as well described. This study compares outcomes SV PTFE a specific emphasis on degree acute limb ischemia caused by graft occlusion. Methods Over 6-year period, 718 infrainguinal revascularization procedures were performed, which 189 (SV, 108; PTFE, 81). Society Vascular Surgery/International Cardiovascular Surgery (SVS/ISCVS) standardized runoff scores calculated from preoperative arteriograms. Clinical categories resulting occlusion graded according SVS/ISCVS standards (I, viable; II, threatened; III, irreversible). Primary salvage at 48 months Kaplan-Meier method. Results Patients matched age, sex, comorbidities. Chronic critical was operative indication in most cases 82%; 80%; P =.85).
