our preliminary results support the view that infrainguinal bypass grafting can be safely done even in diabetics. Despite increased mortality in this group, liberal indication for reconstructive vascular surgery seems to be justified by favourable patency rates and clinical outcome in selected patients.

Although the patency of prosthetic grafts is not as satisfactory as that of autologous vein grafts, the limb salvage rate justifies an aggressive approach to infrapopliteal bypass grafting with polytetrafluoroethylene prostheses when the limb is threatened and vein is not available.
