title: [Surgical treatment for hypertensive cerebellar hemorrhage--indication and characteristics of stereotaxic aspiration surgery].
abstract: From May 1976, through May 1985, eighty-nine patients with hypertensive cerebellar hemorrhage were admitted to our university hospital and affiliated hospitals. The age at onset ranged from 42 to 86 years, with a mean of 65.1 years. Thirty-one of these patients underwent conservative treatment, 20 were given ventricular drainage, 23 underwent suboccipital craniectomy and 15 underwent stereotaxic aspiration surgery. The patients were classified into four categories according to the grading of hypertensive cerebellar hemorrhage proposed by Matsumoto in 1982. Twenty-two cases were of benign type, 20 were moderate type, 30 were severe type, and 17 were fulminant type. The 22 benign type cases showed good recovery (ADL 1 or ADL 2), whereas the mortality rate of severe type cases was 26.7%, and that of fulminant type cases was 70.6%. The site and extension of hematoma were identified by CT. Fourty cases (45.0%) were confined to the left hemisphere, and 19 (21.3%) were localized in the vermis. When the hematoma volume was more than 15 ml, surgical evacuation of the hematoma was considered. Since 1981, stereotaxic aspiration surgery has been performed in cases of hypertensive cerebellar hemorrhage with a mean patient age of 66.9 years, ranging from 51 to 82 years. Patients treated have consisted of 2 with moderate type hemorrhage, 10 with severe type, and 3 with fulminant type, with an overall surgical mortality rate of 33.3%. However, the outcome of fulminant type hemorrhage has remained ADL 2 or ADL 3. The benefits of this type of surgery are that it is not only indicated as an emergency treatment for patients who are aged or at high risk, but that it can be also performed for fulminant type hemorrhage.
