title: The long term behaviour of autogeneou vein by-pass grafts.
abstract: The results of the follow-up of 50 consecutive atuogeneous vein bypass grafts during 1958-65 are described. Arteriography was performed at regular intervals throughout the follow-up lasting from 8-15 years. 11 grafts failed in less than 2 years and were considered technical failures. Thereafter, of the 37 cases on whom arteriographic information is available, a further 5 grafts failed. Deterioration of the graft itself occurred in 19 percent, proximal anastomosis dilatation it 16 percent, and distal anastomosis narrowing in 25 percent. Improvement of flow to the lower leg vessels did not accelerate progression of the long saphenous vein at the time of operation is the limiting factor in longterm graft deterioration. The majority of grafts remained patient without degeneration for up to 15 years.
