Introduction:

Subarachnoid hemorrhage is bleeding in the subarachnoid space. The spontaneous is caused most of the time by rupture of a cerebral aneurysm.

Objective:

Describe the casuistry, management and results of cerebral aneurysms at the Hospital de Clínicas.

Patients and methods:

Observational, descriptive, cross-sectional study including patients operated for cerebral aneurysms, older than 17 years, at the Hospital de Clínicas from 2011 to 2019. The variables described were: age, sex, reason for consultation, radiological studies, Glasgow and Hunt and Hess scale, location, segment, quantity, phase, temporary clipping, vasospasm and hydrocephalus.

Results:

249 patients were included; 45% male, 65% female, average age 47.5 years. The most frequent reason for consultation was headache. At admission they had predominantly Hunt and Hess 2, and Glasgow 15. 43.2% were Fisher 4. The Glasgow of discharge was greater than or equal to 14 in 82.1%. 51.7% were diagnosed with arteriography; 50.9% internal carotid aneurysms, multiple 10.84%. 28.3% were operated in acute phase, 65% late phase, 6.7% were a casually found. In 36.44% of cases a temporary clipping was performed and in 70.4% the lamina terminalis was perforated. Mortality was 4.2%, radiological vasospasm 46%, clinical vasospasm 24.5%, 11% underwent decompressive craniectomy and 5.5% developed VDVP-dependent hydrocephalus.

Conclusion:

The clipping of cerebral aneurysms is a technique with good results and the only one in the public sector.
