We have reported the correlation between the state of HICH (hypertensive intracerebral hemorrhage) at the acute stage, classified into 4 grades of level of consciousness and 5 grades of neurological deficits, and the outcome. So we classified HICH into 7 types (4 types of Putaminal hemorrhage, 3 types of Thalamic hemorrhage) on CT findings, and the outcome. We treated at this time 110 cases of HICH statistically, using Spearman's coefficient of rank correlation, and studied the correlation between each of the level of consciousness, neurological deficits, amount of hematoma, 7 types on CT findings, etc. and the outcome. Then we classified HICH in the acute stage into 4 grades as followings; Grade I: Putaminal and thalamic hemorrhage with the better state of consciousness than 1-3. Grade II: Putaminal hemorrhage with the partial extension to the internal capsule and destruction of it, and with the worse state of consciousness than II-10. Putaminal and thalamic hemorrhage with the neurological deterioration from Grade I, or the advanced hematoma during two weeks. Grade III: Putaminal hemorrhage with almost the total extension to the internal capsule and destruction of it, and with the worse state of consciousness than II-10. Thalamic hemorrhage with the worse state of consciousness than II-10. Grade IV: Putaminal and thalamic hemorrhage with the big intraventricular hematoma.
