Prevalence of Intracranial Saccular Aneurysms in a Japanese Community Based on a Consecutive Autopsy Series During a 30-Year Observation Period

Abstract

Our data suggest that intracranial aneurysms are more frequent in women in the general Japanese population. Aneurysms are more prevalent in the middle cerebral artery, but the risk of rupture is highest in the vertebrobasilar system.
