Ruptured middle cerebral artery aneurysm

The records of 49 patients with ruptured middle cerebral artery aneurysm with large intracranial hematomas treated with hematoma evacuation and aneurysm clipping between January 2000 and December 2013 were retrospectively reviewed.

Within this cohort, 35 patients (71.4%) were Hunt and Hess grade IV or V on presentation. The mean hematoma volume was 100.4 ± 77.2 mL. Craniectomy was performed in 40 patients (81.6%). Angiographic vasospasm developed in 15 patients (30.6%). The in-hospital mortality rate was 28.6% (14 patients). At a mean of 25.3 ± 34.0 months follow-up, a good outcome (modified Rankin Scale [mRS] score 0-3) was observed in 18 patients (36.7%).

Significant factors associated with poor outcome or death (mRS scores of 4-6) included increasing age (P < .01), increasing Hunt and Hess grade (P = .03), increasing modified Fisher grade (P = .01), presence of intraventricular hemorrhage (P < .01), decreasing percentage of hematoma evacuation (P < .05), need for craniectomy (P <. 01), need for external ventricular drainage (P = .04), and angiographic vasospasm (P = .02) 1).
