Abstract
The in situ vein bypass procedure has been rendered much simpler and less demanding after destruction of the valves was achieved by new types of intraluminal valve strippers. The stripper is introduced from the distal end of the vein and retracted several times. Amongst the first 50 patients operated on, there were 2 postoperative deaths. 94% of the vein grafts were patent at discharge. 80% of the grafts were patent at follow-up from 4 to 27 months. The cause of late occlusions seems in most cases to be advanced arteriosclerotic disease, and not inadequate destruction of the valves.
