  3. Provide patency equal to that of autogenous saphenous vein for above-knee femoropopliteal bypass.
  4. May be more resistant than Dacron grafts to pseudoaneurysm formation.
  5. Are currently the prosthetic graft of choice for hemodialysis access.

D. May be more resistant than Dacron grafts to pseudoaneurysm formation.

E. Are currently the prosthetic graft of choice for hemodialysis access.

DISCUSSION: PTFE grafts are manufactured from a unique polymer extrusion process and are not textile grafts. For most surgeons they are currently the prosthetic graft of choice for hemodialysis access. For suprainguinal bypass, PTFE and Dacron provide comparable patency, although PTFE grafts may be more resistant than Dacron grafts to pseudoaneurysm formation. PTFE at all levels in comparable patients is inferior to good-quality saphenous vein for infrainguinal bypass.
