Surgical outcome of multiple intracranial aneurysms

Abstract

Multiple intracranial aneurysms are relatively uncommon among patients of intracranial aneurysms. The aim of management has traditionally been the same i.e. clipping of all the aneurysms to eliminate the risk of rebleed. This study was conducted to determine the outcome of patients of multiple intracranial aneurysms at Mayo Hospital Lahore, Pakistan. The study period was from September 1999 to January 2002. Four patients were diagnosed having multiple intracranial aneurysms. Age range was 40 to 65 years and 2 (50%) patients were female. Patients were assessed according to Hunt & Hess grade. Clinical presentation was favoring the site of ruptured aneurysm in one patient and CT brain was suggestive of site in two patients. All patients had 2 aneurysms. In three (75%) cases, aneurysm were unilateral and in one (25%) case, bilateral. Half (50%) patients had clipping of aneurysms through single craniotomy and half (50%) had bilateral craniotomies. Outcome was graded according to Glasgow Outcome Scale. Three (7 5%) patients had good outcome and one (25%) patient died after clipping of aneurysms due to vasospasm, infarction and metabolic disturbance.
