RESUMEN
The optimum timing of surgery for ruptured intracranial aneurysms still remains controversial. In order to compare the total management outcome between early and late surgery a retrospective analysis was carried out. Of 159 patients, 97 patients were selected according to the entry criteria and were divided into two groups ; group I(46pts.) was early surgery planned patients and group II(51 pts.) was late surgery planned patients. The results obtained are as follows ; 1) The incidence of a good recovery for the early surgery planned group was 74%, and that of the late surgery planned group was 67%, but there was no statistically significant difference between two groups. 2) The incidence of a delayed ischemic deficit was 24% for the early surgery planned group, and 29% for the late surgery planned group, with no statistically significant difference. But, the incidence of rebleeding was 2% for the early surgery group, and 14% for the late surgery planned group, so there was a statistically significant difference here. 3) The total management outcome of the early and late surgery planned group was similar, but early surgery was advantageous for the prevention of rebleeding.
