Does treatment of ruptured intracranial aneurysms within 24 hours improve clinical outcome?

Abstract

Background and Purpose- The purpose of this study was to analyze whether treating ruptured intracranial aneurysms within 24 hours of subarachnoid hemorrhage improves clinical outcome. Methods- An 11-year database of consecutive ruptured intracranial aneurysms treated with endovascular coiling or craniotomy and clipping was analyzed. Outcome was measured by the modified Rankin Scale at 6 months. Our policy is to treat all cases within 24 hours of subarachnoid hemorrhage. Treatment delays are due to nonclinical logistical factors. Results- Two hundred thirty cases were coiled or clipped within 24 hours of subarachnoid hemorrhage and 229 at >24 hours. No difference in age, gender, smoking, fami..
