Vein graft stenosis. Characteristics and effect of treatment.
One hundred seventy-three femoropopliteal vein grafts were followed carefully for a minimum of 4 years. Twenty percent developed stenosis in the graft or associated with an anastomosis, usually within 2 years. Appropriate secondary operations were effective in increasing 5 year patency by an estimated 16 percent. Thirteen thrombosed vein grafts treated by early thrombectomy and revision gave poor results. Strict follow-up is recommended. Urgent operation is advocated for tight stenosis to avoid the consequences of graft thrombosis.
