Clinical phenomena and their correlation to angiographic findings in cerebrovascular disease.

Seventy-one patients who had cerebral angiography because of clinical evidence of focal ischemic cerebrovascular disease were studied. Seventy-seven per cent of these patients had an arterial lesion in the distribution appropriate to the symptoms. However, the degree of dissemination of the atherosclerotic lesions, lesion morphology and severity of stenosis could not be predicted from the clinical manifestations. The presence of atherosclerotic cerebrovascular disease can usually be predicted by analysis of the symptoms and signs, but the nature and extent of the lesions can only be determined using cerebral angiography.
