Clinical Analysis of Ruptured Intracranial Aneurysms

ABSTRACT

The author analyzed 177 consecutive cases of saccular, ruptured intracranial aneurysms admitted to the Department of Neurosurgery in Korea University Hospital during the period from August 1983 to July 1987. the results of analysis were summarized as follows. 1) Mean age of the patients was 50.4 years. 2) Incidence of clinical vasospasm was 27.2%(46/177) and of rebleeding was 10.7%(19/177). 3) Surgery was done for patients which accounts for 57.6% of all patients. Functional recovery was noted in 84 of the these surgically treated patients(84.6%). 4) The prognostic factors are age, hypertension, size of aneurysm, site of aneurysm, preoperative neurological state, vasospasm, hydrocephalus, rebleeding, timing of operation, multiplicity. 5) The mean size of aneurysms was 6.9mm. The direction of aneurysms was variable, but most of them pointed in the direction of blood flow in afferent arteries.
