Cerebral arteriovenous malformations associated with aneurysms--a report of 10 cases and literature review.
We analysed 10 cases of arteriovenous malformations (AVMs) associated with aneurysms and reviewed the literature in order to confirm the clinical characteristics of AVMs associated with aneurysms. The mean incidence of aneurysms in our AVM population was 9.1% and the average age was 38 years. The ratio of male to female was 1.3 to 1. The aneurysms (40-96%) were often located on a feeding artery and seldom (23%) at an arterial bifurcation. The mortality rate was 0-26% in surgically managed patients and 38-60% in conservatively treated patients. The combination of intracranial vascular lesions is not rare. Most patients presented with symptoms referable to their AVMs. Treating both lesions in a single operation is the best option. The prognoses for most patients was good.
