    Abstract:
    The clinical course of patients with subarachnoid hemorrhage (SAH) due to rupture of cerebral aneurysm admitted during the last five years is analysed: 157 patients were treated by direct surgical approach of the aneurysm, 58 localized in the anterior communicating artery (ACoA), 48 in the internal carotid artery (ICA), 43 in the middle cerebral artery (MCA), and 8 in the posterior circulation. Fourty-four patients were operated on during the first 72 hours (early surgery), 40 during the 4th and 7th days, 16 during the 8th and the 10th, and 57 after the 10th (late surgery). According to main localizations, the outcome of patients with aneurysms in the ACoA was good in 79.1%, in the ICA in 69.7%, and in the MCA in 69.7%. Patients treated in Hunt & Hess grade I and II had both good results in 77.5%, grade III patients had good results in 71.3%, and grade IV in 56.2%. According to timing of surgery good results were observed in 61.4% for patients submitted to early surgery, in 80% for patients treated during the 4th and 7th days, in 81.2% for patients treated during the 8th and the 10th days, and in 70.2% for that submitted to late surgery. The overall mortality was 14.6%. For grade I patients mortality was 6.4%, for grade II was 12.2%, for grade III was 15.2%, for grade IV was 25%, and all patients operated on in grade V died.(ABSTRACT TRUNCATED AT 250 WORDS)
