title: [Surgical treatment of hypertensive cerebellar hemorrhage; stereotactic aspiration surgery vs suboccipital craniectomy].
abstract: Patients with severe types of hypertensive cerebellar hemorrhage have been treated usually by suboccipital craniectomy and hematoma evacuation. However, since 1981, we have treated such patients with stereotactic aspiration surgery. The purpose of this study was to evaluate the prognosis of patients treated by stereotactic aspiration surgery for cerebellar hemorrhage in comparison with those who underwent suboccipital craniectomy. Between May 1976 and December 1989, 246 patients with hypertensive cerebellar hemorrhage were admitted to our university hospital and affiliated hospitals. The patients were classified into four categories according to the grading of hypertensive cerebellar hemorrhage proposed by Matsumoto in 1982; benign, moderate, severe, and fulminant. Then we decided the most appropriate therapy according to this grading. Fifty-nine patients (24.0%) underwent suboccipital craniectomy and 38 (15.4%) underwent stereotactic aspiration surgery. There was no significant difference in the postoperative outcome between suboccipital craniectomy and stereotactic aspiration surgery in the overall study. However prognosis of the fulminant type was significantly better with stereotactic aspiration surgery than with suboccipital craniectomy. Possible reasons for this include: 1) All patients of this type who underwent aspiration surgery had this procedure within 12 hours after the onset of cerebellar hemorrhage. 2) The hematoma volume of most patients of this type who had aspiration surgery was under 30ml. 3) The age of all patients of this type with aspiration surgery was under 70 years old. In conclusion, we suggest that aspiration surgery for hypertensive cerebellar hemorrhage is indicated for all patients with moderate, severe and fulminant types of hemorrhage.
