Factors influenced on prognosis of reconstructive surgery for peripheral arterial occlusion: comparative study between arteriosclerosis obliterans and thromboangiitis obliterans.
Reconstructive surgery was carried out in 93 patients of ASO and TAO. Factors influenced on prognosis were studied being compared with ASO and TAO. Cumulative 5-year patency was 60% in ASO and 25% in TAO. Distal patency was shown by total score given in each site of arteriogram. Patency rate was well correlated with combinated factors such as total score of arteriogram and back flow at site of surgery. Period from onset of symptom to surgery and site of operation also correlated with patency statistically, though total serum cholesterol, ischemic time at reconstructive surgery, and amount of bleeding at operation did not relate to prognosis. Causes of early failure and special problems of late failure in TAO were studied.
