Femoropopliteal vein grafts for intermittent claudication

Femoropopliteal vein grafts were performed for intermittent claudication in 160 patients (182 legs) over a 12-year period. The accumulative patency rate was 67 per cent at 5 years. However, patency rates improved significantly in the latter 6 years of the study, to 75 per cent at 5 years. Early postoperative occlusion and morbidity rates also markedly declined in this latter period. Patency rates were significantly better in males than in females, in patients who were able to stop smoking after operation and in legs with a three-vessel run-off compared with those with a two- or one-vessel run-off. The patients' age did not influence graft patency rates.
