A Clinico ? Epidemiologic study was done on 300 cases of Cerebrovascular accidents confirmed by C-T Scan, mainly admitted to the 3rd I.C.U. of Kyung Hee Univ. Medical College Hospital, managed from october 1978 to October 1988.
The observed results were as follows:
1. The ratio of Male to Female was 1.54:1 in whole cases; 1.73:1 in (intra) cerebral hemorrhage, 1.34:1 in subarachnoid hemorrhage, and 1.34:1 in cerebral infarction.
2. The age distribution showed that the 6th decade was most frequent in the incidence, followed by the 7th, 5th, over 8th, 4th, and under 3rd decade in turn.
3. Among 300 cases of cerebrovascular accidents, cerebral hemorrhages were 164 cases (54.7%),
subarachnoid hemorrhages 61 cases (20.3%), and cerebral infarction 75 cases (25%).
4. Cerebral hemorrhage and subarachnoid hemorrhage showed the peak age incidence in the 6th decade,
cerebral infarction in the 7th decade.
5. Hypertension was present in 64.3% of overall cases; in 74.4% of cerebral hemorrhage, in 47.5% of subarachnoid hemorrhage, and in 56.0% of cerebral infarction.
6. The lost or impaired consciousness was noted in 89.6% of cerebral hemorrhage, in 55.7% of subarachnoid hemorrhage, and in 50.6% of cerebral infarction. The hemiparesis was noted in 59.1% of cerebral hemorrhage, in 17.1% of subarachnoid hemorrhage, and in 62.7% of cerebral ingarction.
7. The most frequent site of cerebral hemorrhage was basal ganglia (42.1%), followed by cerebrum (19.5%), thalamus (16.4%), etc. Aneurysms were found among the 27 cases taken angiography, the most frequent site was anterior communicating artery (40.7%), followed by middle cerebral cerebral a. (25.9%), posterior communicating a. (22.2%), and anterior cerebral a. (11.2%). The sites of cerebral infarction were basal ganglia (16.0%), frontal lobe (14.6%), multiple (13.3%), occipital lobe (12.0%), and etc. in that order.
8. The prognosis was relatively good in overall. Good prognosis was noted in 57.9% of Cerebral hemorrhage, in 52.4% of subarachnoid hemorrhage, and in 85.3% of cerebral infarction.
