ABSTRACT |
Brain Computerized Tomography(CT) and cerebral angiography were reviewed in thirty-six patients with multiple intracranial aneurysms(22.5%) among the 160 consecutive surgical cases of intracranial aneurysms. The prevalent sites of multiple aneurysms were the middle cerebral artery(37.0%), posterior communicating artery(22.2%), and internal carotid artery(14.8%) in sequence. However, the vertebrobasilar system(83.3%), anterior communicating artery(63.6%), and posterior communicating artery(50.0%) had higher probability of rupture than internal carotid artery(8.3%) or middle cerebral artery(33.3%). Based on CT and angiographic information, the site of rupture can be predicted with a high degree of reliability. These factors were the presence of localized hemorrhage on CT, focal vasospasm, size and irregularity of aneurysms, and relative hyperplasia of parent artery. |
