Abstract
Diffuse tortuosity and dilatation due to arteriosclerotic degeneration of the cerebrovascular tree and vessel kinking secondary to arteriosclerosis are more frequent in the Negro than in the Caucasian. Conversely, large atherosclerotic plaques of the proximal cervical cerebral arteries are more frequent in the Caucasian than in the Negro. Fifty-eight cases or 33.7% of this series of subjects entering a general hospital with complaints of cerebrovascular disease were found by arteriographic investigation to have surgically accessible lesions causing arterial obstruction. Reconstruction procedures were only performed in 20 cases (11.6%). The mortality rate was 15% in this preliminary group treated by medical means (supportive, anticoagulants or fibrinolysin or both) plus surgery. The mortality rate in the group treated by medical means alone was 4.5%.
