[Hydrocephalus and its significance in the early surgical treatment of cerebral aneurysms].

The clinical course of acute arterial aneurysm rupture and computed tomographic findings of the brain were analysed in 100 patients. Hydrocephalus was detected in 27% of cases. There was a relationship between the development of hydrocephalus and the nature of intracranial hemorrhage, the site of aneurysm, as well as the specific features of neurological symptomatology in hydrocephalus. Analyzing the results of surgical treatment of aneurysms in 85 patients indicated that there was an increase in the number of unfavourable functional outcomes and a decrease in good ones after early operations made in the presence of hydrocephalus.
