Abstract
Objective: Although autologous veins are the first-choice conduit for femorotibial artery bypass, if there are no appropriate autologous veins, we perform femorotibial artery bypass using polytetrafluoroethylene (PTFE) with a distal vein cuff for patients with critical limb ischemia (CLI). This study examined the long-term outcomes of femorotibial artery bypass using PTFE with a Miller's cuff. Materials and Methods: Using prospectively collected data for 444 distal bypasses, a retrospective analysis was conducted for 32 femorotibial PTFE bypasses with a Miller's cuff (PTFE-Miller's cuff) performed for patients with CLI from April 1994 to December 2016. Results: Primary and secondary patency rates of PTFE-Miller's cuff at 3 years were 35.8% and 51.2%, respectively. Limb salvage rate of PTFE-Miller's cuff at 3 years was 71.0%. Conclusion: Although the patency rate was low and failed to yield satisfactory results, the limb salvage rate remained relatively high. Femorotibial PTFE bypass with a Miller's cuff was a useful technique of limb salvage for patients with CLI in whom an appropriate autologous vein could not be used.
