Angiographic findings were analysed in 22 cases of coronary occlusive disease which were selected from 50 cases of coronary arteriographies done in Department of Radiology, Seoul National University Hospital from September, 1981 to August, 1984. There were 16 cases of single vessel disease, in which 12 were LAD involvement and 4 were RCA involvement, 2 cases of two vessel and 4 cases of three vessel disease. Site, degree and extent of stenotic invelvement in those occlusive coronary diseases were analysed with review of literature for selective coronary arteriography. Since coronary arteriography is the final and accurate examination for the evaluation of occlusive coronary arterial disease, it is expected to be widely used for the diagnosis of occlusive coronary arterial disease which is rapidly increasing recently in this country.
