Abstract
Clinical course, results of angiography and computerized tomography (CT) were compared in 204 patients with focal cerebral ischemias. The extent and the importance of the radiological results depend on the localization of the affected area, whereby essential differences exist between extra- and intracranial arteries as well as between the vertebrobasilar and the carotid arterial flow region. As to the carotid arterial system there appear to be significant correlations between the size of the infarction on the CT and the extent of the vessel stenosis on angiography. Furthermore the likelihood of deficit recovery is inversely proportional to the degree of pathology seen in both radiologic examinations. It is discussed whether these correlations, obtained from the examination of a great number of patients, can help to evaluate the significance of equivocal angiographic findings in individual cases.
