Multiple Aneurysm-Which One Ruptured?

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.

A Case of Symptomatic Vertebral Hemangioma with Epidural Mass

A case of upper thoracic vertebral hemangioma with epidural mass is reported. Preoperative selective angiography with embolization is the procedure of choice for reducing intraoperative bleeding. There was progressive postoperative improvement of the myelopathy.

The Role of Stereotactic Endoscopy in Ventricular and Juxtaventricular Lesions

The authors have been performed stereotactic endoscopy to diagnose and treat 6 cases of ventricular and juxtaventricular lesions using Brown-Wells system under the local anesthesua. We thought that stereotactic endoscopy was easier and safer than conventional surgery for these lesions.
