title: [Cerebral artery aneurysms: Clinico-anatomic analysis of 610 cases].
abstract: Analysis of 610 aneurysms in 537 patients is performed. Main localization of aneurysms (88.7%) was the anterior region of Willis's circle. Congenital dysplasias of the arterial wall are transformed into the aneurysm when the risk factors join (essential or transitory arterial hypertension, atherosclerosis) this being confirmed by an advanced age (63%). Subarachnoidal hemorrhages predominated (29.9%). Most frequent immediate causes of death were hemorrhage into the brain ventricles (42.9%), edema and brain dislocation (40.7%). Ischemic brain softening played a role in the anatogenesis among non-operated patients in 7.3% cases and in 37.1% among operated patients. Histologic examination revealed that the maximum of repeated hemorrhages occur during the first 14 days after the aneurysm rupture-the time of noncompleted thrombus organization.
