[Long-term results of reversed venous femoro-popliteal bypass. Apropos of 151 cases].

Of 151 inversed autogenous vein grafting done in 137 patients for femoro-popliteal disease, 97 (65%) have been done for severe ischemia (rest pain or gangrene); others (35%) have been done for severe walking pain or popliteal and/or femoro-popliteal aneurysms. The follow-up is of 13 years. Hospital mortality was 5 (3,3%). Early failure is of 6%. Patency rate at 5 years is 60% and at 10 years 46%. The lower the anastomosis is done on the popliteal artery the better is the long-term patency rate. The worst results are in diabetic and younger patients. Technic of in situ vein grafting would have not allowed 26% of patients venous revascularization because of the poor condition of the saphenous vein, that the inversed technic permitted (on using internal + external saphenous, resection-suture, etc).
