    Abstract

    Eight hundred twenty-two polytetrafluoroethylene (PTFE) grafts were used in arterial reconstructions for lower limb ischemia over the last eight years at Montefiore Medical Center, Albert Einstein College of Medicine. Four hundred twenty-seven femoropopliteal reconstructions with PTFE had a six-year cumulative life table patency rate of 55%, with follow-up of seventy-six grafts for more than three years and twenty-eight grafts for more than four years. Seventy-nine bypasses to an isolated popliteal segment had a six-year cumulative patency rate of 72%. There were 207 bypasses performed to the tibial, peroneal, or dorsalis pedis arteries. Life table patency rates were 55% at one year, 40% at two years, and 37% at four years. Ninety-two PTFE femorofemoral and sixty-two axillofemoral bypasses had a five-and-one-half-year cumulative life table patency rates of 83 and 75%, respectively. Axillopopliteal PTFE bypasses can salvage otherwise doomed limbs. Thirty-four such grafts had 74% one-year and 45% five-year patency rates. The overall infection rate in all 822 PTFE grafts was only 0.5%. Thus, PTFE is a promising vascular prosthetic material that can facilitate otherwise difficult or impossible limb salvage procedures.
