The prognostic value of emergency microsurgical clipping of ruptured anterior circulation aneurysms.

ABSTRACT

BACKGROUND: The treatment of aneurysmal subarachnoid hemorrhage poses a formidable challenge, given the high mortality rate and associated mortality. Current recommendations are for treatment to be initiated within 24 hours of diagnosis. METHODS: In our study, we compared a cohort of 66 patients who received prompt microsurgical treatment within 6 hours of diagnosis with a cohort of 51 patients who received prompt microsurgical treatment within 12 hours of diagnosis. RESULTS: The modified Rankin Scale was utilized to evaluate the follow-up of patients at 30 days, 12 months, and 18 months following surgery. We performed a parametric comparison of the distributions of the means of groups, and our results indicate that treatment within 6 hours of diagnosis results in a lower incidence of obstructive hydrocephalus and a more favorable outcome. CONCLUSIONS: A favorable outcome was observed in patients who were treated within 6 hours. The availability of a specialized vascular team ensures the highest levels of care.
