Abstract/OtherAbstract:
Background: In spite of its common occurrence, the factors predictive of the rupture of intracranial aneurysms (IAs) remain poorly defined. Method: A retrospective analysis of patients admitted with a primary diagnosis of cerebral aneurysm in a single institution was done. The factors studied were age, sex, size, site, side, multiplicity, neck type, aspect ratio, positive family history, smoking and drinking habits, and hypertension. The morphological parameters were evaluated for a total of 5,138 aneurysms obtained from the 2,347 patients. Factors found significant on univariate analysis were further tested on a multivariate model. Findings: We found 1,088 patients (46.36%) had at least a single aneurysmal rupture. Among the morphologic factors, size greater than 10 mm, right sidedness, aspect ratio greater than 1.6, deviated neck type, and multiplicity were found to be associated with higher incidences of rupture. Aneurysms on posterior communicating and middle cerebral arteries were found to be more prone to rupture. The demographic factors that were more linked with the ruptured aneurysms were positive family history, smoking, and hypertension. Conclusions: Relevant cases should be started on intensive lifestyle modification, and extensive screening of those with a positive family history is highly warranted. All "at-risk" patients should be evaluated for early surgical intervention.
