title: [Long-term prognosis of cerebral infarction--influence of arterial stenotic lesion for survival (author's transl)].
abstract: Cerebral four vessel angiography was performed in 85 patients with non-embolic cerebral infarction and followed for ten years. Of 45 patients with arterial stenosis of 25 per cent or more, 21 (46.7%) survived at 5 years and 12 (26.7%) at 10 years after onset of the stroke. In contrast, survivors of 45 patients with stenosis less than 25 per cent or with no stenotic lesion, were 35 (87.5%) at 5 years and 29 (72.5%) at 10 years after the onset. The survival rate of the former patients group was lower significantly than the expected survival rate in a general population. Arterial stenosis of 25 per cent or more suggested a trend of poor prognosis in patients with multiple stenosis, especially those of bilateral internal carotid arteries, and of better prognosis in patients with stenosis in vertebrobasilar system. Patients with stenosis of 50 per cent or more in sphenoidal portion of the middle cerebral artery seemed to have a poor prognosis than those in the internal carotid artery.
