The 5 year results using polytetrafluoroethylene (PTFE-Gore-Tex) grafts mainly for superficial femoral occlusion have been reviewed. The majority of these grafts were inserted in an elderly poor risk group of patients with critical ischaemia of the lower limb. The overall cumulative patency at 2 years was 29% falling to 18% at 5 years. Further analyses were performed to take into account risk factors, namely, patient's age, diabetes, hypertension, continuation of smoking, peroperative angiographic findings and the site of the distal graft anastomosis. Peroperative angiographic run off was found to be the only risk factor significantly affecting the cumulative graft patency. The presence of diabetes was found to have a significant detrimental effect on limb salvage.
