Treatment of SFA occlusions (TASC IIB and C or Imelda Ia and II) should be done by PTFE bypass rather than by PTFE thrupass, as thrupass is connected with worse early outcome. These results represent only a small category of femoral disease.

Adjuvant AV-fistula does not improve the patency of a femorocrural PTFE bypass with a distal vein cuff.

In a group of diabetic patients increased flow in a vascular bypass graft was achieved by an internal av-fistula within a radial forearm flap. This method is useful in selected cases with poor run off and large ischaemic lesions.

The adjuvant AV fistula increased graft flow significantly in a poor-outflow venous bypass. In this extreme patient group, acceptable patency and leg salvage was achieved without adverse effects. Despite this, the AV fistula did not improve the outcome.

The adjuvant av-fistula neither caused any adverse effects nor had any effect on patency.
