Peripheral Arterial Bypass Graft - Vascular Society

Artificial Dacron or PTFE grafts are used to bypass larger arteries, but below the groin the smaller femoral and popliteal vessels are often best bypassed using the patients own vein. The long saphenous vein is ideally situated for this. ... At release of clamps blood will then flow through the graft, bypassing the diseased segment.

The effect of anticoagulation therapy and graft …

Objective: A recent retrospective study showed that the ischemic consequences of femoropopliteal bypass graft occlusion were more severe with polytetrafluoroethylene (PTFE) than with vein. This study examines this conclusion and whether oral anticoagulation therapy reduces the degree of ischemia after occlusion of PTFE and vein femoropopliteal bypass grafts.

1998-12-1 · Gore-tex and Impra PTFE grafts differ from each other in the way they are manufactured. When PTFE was initially used in hemodialysis conduits, aneurysmal dilation occurred in the graft secondary to repeated needle punctures. Gore-tex solved this problem by adding an outer wrap of porous PTFE to reinforce the graft.
