Sequential Changes of Cerebral Blood Flow in Patients with Hypertensive Intracerebral Hematoma with Surgical Intervention

Abstract

We investigated the relation between cerebral blood flow (CBF) and surgical procedures in patients with surgically treated hypertensive putaminal hematomas. The subjects were 20 patients with hypertensive putaminal hematomas, consisting of 10 with stereotactic aspiration of hematomas and 10 with evacuation of hematomas. CBF was determined by means of stable xenon-enhanced computed tomography before and after surgery and in the chronic stage. The mean global CBF of the subjects was reduced in accordance with hematoma volume. CBF on the hematoma side was not markedly improved after evacuation for removal of hematoma to compared with that after aspiration for removal of hematoma. These results suggest that aspiration for removal of hematoma might be beneficial for patients with hypertensive putaminal hematomas from the aspect of CBF.
