The effect of distal anastomotic site on PTFE graft patency in lower extremity bypass.
The site of distal anastomosis of polytetrafluorethylene (PTFE) lower extremity bypass grafts may significantly affect results. We examined patency in 144 cases; 45 femoro-popliteal above knee (AK), 55 femoro-popliteal below the knee (BK) and 44 femoro-distal (D) PTFE bypasses, the groups being comparable with regard to other risk factors studied. Cumulative graft patency at 3 years was 71.3% for AK, 36.7% for BK, 16.4% for D and overall 35%. The site of distal anastomosis is an important determinant, of PTFE lower extremity bypass patency. We have abandoned the use of PTFE for BK and D, but feel that AK PTFE is a suitable alternative to autogenous reversed saphenous vein.
