Abstract

The present study aimed to evaluate the impact of early surgical evacuation of sylvian hematoma caused by ruptured middle cerebral artery (MCA) aneurysm on clinical outcome after subarachnoid hemorrhage. Hospital records and computed tomography scans for 26 patients with MCA aneurysm who underwent surgical clipping between June 2001 and January 2008 were retrospectively reviewed. All patients presented with sylvian hematoma associated with subarachnoid hemorrhage and received surgery at 7.9 ± 3.6 (mean ± standard deviation) hours of ictus. They were divided postoperatively into two groups, achievement (n = 16) and non-achievement (n = 10) of extensive hematoma evacuation, and their clinical course and functional outcomes were compared. The frequencies of delayed ischemic neurological deficit and vasospasm-related cerebral infarction were significantly less (p < 0.05) in the achievement group. Better functional outcomes were obtained in patients with successful evacuation (p < 0.05), as assessed by improvement of hemiparesis on manual muscle testing scale at postoperative 1- month follow up and by the modified Rankin scale at postoperative 3 and 6 months. Clinical outcomes were also better in the achievement group. These results suggest that better clinical course and outcome can be expected in patients who undergo early successful hematoma evacuation with surgical clipping of a ruptured MCA aneurysm.
