Abstract
CT-guided stereotactic operation was performed in 55 patients with hypertensive intracerebral hematoma. Location of the hematoma was putamen in 28 cases, thalamus in 14 cases, subcortical area in 9 cases, cerebellum in 3 cases and pons in one case. Ages ranged from 36 to 85 years (mean 59.5). The mean timing of the surgery after bleeding was 4.2 days. The estimated volume of the hematoma on CT was 8ml to 57ml in putaminal, 9ml to 40ml in thalamic, 18ml to 77ml in subcortical, 17ml to 26ml in cerebellar and 5ml in pontine hemorrhage. Aspiration rate at surgery was 60.4% in putaminal, 37.9% in thalamic, 41.7% in subcortical, 45.2% in cerebellar and 30% in pontine hemorrhage. In addition, we evaluated ADL at 6 months postoperatively in patients with putaminal and thalamic hemorrhage. It is concluded that stereotactic operation is advisable in those cases with 10 to 50ml hematoma volumes in putamen or thalamus. On the other hand, in cases with over 50ml volume, hematoma should be evacuated by craniotomy.
