[Hemorrhage caused by cerebral arterial aneurysm].

The analysis of clinical pictures and pathomorphology of cerebral damage (intra-operative and autopsy material) was performed on 387 patients with first or second rupture of cerebral arterial aneurysms. Clinicopathological peculiarities of the aneurysmic intracranial hemorrhages were derived. Intracranial pathomorphological determinants of the severity of the patients' conditions at the acute stage were determined, including the intracerebral hematomas resulting in dislocation syndrome and paving the way to penetration of arterial blood spring into the ventricles on the second rupture of the aneurysm. The clinical course of the condition featured a stabilization period whose duration depended on both the type of hemorrhage and cerebral response. This period was regarded as optimal for reconsidering an option of surgical intervention.
