Digital substration angiography in occlusive disease of the lower extremity
Abstract
- In recent years, digital subtraction angiography(DSA) has assumed agreater clincal and surgical significance,especially since the advent of arterial grafting for occlusive arterial disease. Evaluation of the site and extentof semental occlusion, the state of the distal arterial tree and the degree of collateral circulation can best beobtained by DSA. From January 1987 to July 1989.DSA was performed on 19 occlusive arterial disease of the lowerextremity: 12 arteriosclerosis obliterans and 7 buergr's disease. The dubjects were 19 patients ranging from 18 to76 years of age. All patients wera male. Average age of patients with arteriosclerosis obleterans/Buerger'sdisease was 63 and 35, respectively. The angiographic findings were abrupt occlusion or irregular narrowing witharteriosclerotic change of aorta in arteriosclerosis obliterans and abrupt occlusion or narrowing withoutarteriosclerotic change of aorta in Buerger's disease. The most frequently involved artery in occlusive diseasewas superficial femoral artery(10/19). Run-off artery shows in 7 cases of arteriosclerosis obliterans and in 3cases of Buerger's disease. Arteriography is the most valuable diagnostic tool to confirm the occlusive vasculardisease and also to decide appropriate treatment modality.
