The purpose of this study was to set the guidelines for selection of patients to do early surgery in ruptured intracranial aneurysm. We assessed 706 patients with single rupture and without large hematoma, who underwent aneurysm surgery from 1985 to 1995. The male and female ratio was 1:1.5. Among the 706 patients, early surgery was performed in 214 cases. The results of early surgery were good in 193 cases(90.2%), fair in 13 cases(6.0%), poor in 1 case(0.5%) and dead in 7 cases(3.3%). The rate of dead outcome in the early surgery group was higher compared to other timing groups. The Fisher group 1, 2 and 3 reveale good outcome in early surgery group;92.6%, 96.3%, 88.8% respectively. The incidence of delayed ischemic deficits(DID) of early surgery group was same as other groups. However, in Fisher group 3, the incidence of DID was significantly low, 32.5%, in early surgery group. It is suggested that the criteria of selection of early surgery in patients with ruptured intracranial aneurysm would include as follows:1) patients with good clinical grade, 2) poor grade patients with marked irritability, acute hydrocephalus, and poorly controlled hypertension, 3) none-complex aneurysm requiring less brain retraction, dissection and brief temporary clipping, 4) age under 60 or over 60 with good physical status, and 5) Fisher group 3 requiring cisternal larvage and anticipated triple-H therapy.
Key Words: Ruptured intracranial aneurysm; Early surgery; Fisher group 3; Delayed ischemic deficits
