A technique of arterial reconstruction suitable for patients with extensive arterial occlusions and for previous failed arterial surgery is described. The "hitch-hike" graft consists of a proximal limb of 6-mm velour Dacron prosthesis and a distal limb of autogenous vein. The intermediate prosthesis-to-vein anastomosis is made into an endarterectomized segment of upper popliteal artery. The results in the first 16 limbs are described. Eleven grafts are functioning from 2 to 14 months after operation and 5 of these have functioned for more than 1 year. The advantages of the technique are: long arterial occlusions may be bridged; autogenous vein is used to cross the knee joint; good measured blood flows may be demonstrated at operation; acceptable patency rates may be obtained up to 1 year.
