[Multiple intracranial aneurysms].

Thirty eight patients with multiple intracranial aneurysms were studied. They correspond to 19.4% of all aneurysms treated over a twelve year period in the Servidores do Estado Hospital. 89 aneurysms and 4 infundibuli were detected. In 71.0% of the patients, two aneurysms were found; in 18.4%, three aneurysms; and in 10.4%, 4 or 5 aneurysms were observed. Twenty-seven patients were women and 11 men, ranging in age from 16 to 72 (average 47 years old). Subarachnoid hemorrhage was found in 36 patients (86.8%). The operative mortality in this series was 3.5%. We concluded that patients with multiple intracranial aneurysms should have all aneurysms, that can bleed, clipped through standard micro-neurosurgery technics.
