Digital substration angiography in occlusive disease of the lower extremity

In recent years, digital subtraction angiography(DSA) has assumed a greater clinical and surgical significance, especially since the advent of arterial grafting for occlusive arterial disease. Evaluation of the site and extent of segmental occlusion, the state of the distal arterial tree and the degree of collateral circulation can best be obtained by DSA. From January 1987 to July 1989. DSA was performed on 19 occlusive arterial disease of the lower extremity; 12 arteriosclerosis obliterans and 7 Buerger's disease. The subject were 19 patients ranging from 18 to 76 years of age. All patients were male. Average age of patients with arteriosclerosis obliterans/Buerger's disease was 63 and 35, respectively. The angiographic findings were abrupt occlusion or irregular narrowing with arteriosclerotic change of aorta in arteriosclerosis obliterans and abrupt occlusion or narrowing without arteriosclerotic change of aorta in Buerger's disease. The most frequently involved artery in occlusive disease was superficial femoral artery (10/19). Run off artery shows in 7 cases of arteriosclerosis obliterans and in 3 cases of Buerger's disease and also to decide appropriate treatment modality
