[The treatment of cerebral aneurysm in elderly patients in the acute period of subarachnoid hemorrhage].

Seven hundreds and forty-nine patients after subarachnoid hemorrhage developed as a result of the rupture of cerebral aneurysm, including 117 (15.6%) people aged 60 years and over (elderly patients) and 632 (83.4%) patients younger than 60 years old, were examined. In these groups severity of a patient's state before the surgery, presence of concomitant pathology, data of instrumental examination, outcome of the surgery were compared. The fatal outcome after the surgery was higher in elderly patients than in younger ones (17.4% versus 12.4%) that might be explained by the greater severity of their state after the development of subarachnoid hemorrhage and higher incidence of hypertensive disease and other concomitant diseases. Clinically significant angiospasm and non-resorptive hydrocephalus were observed in this group most frequently.
