ABSTRACT
From January 1990 to January 1996, we analyzed outcome according to the distribution of aneurysms, the type of surgical treatment, the timing of operation, and the patient's pre-operative status in a total of 54 cases of multiple intracranial aneurysms. The frequency of multiple intracranial aneurysms was 13.4% and the sex ratio was 1:2 with female being predominant. The frequency of aneurismal location was MCA(35.0%), P-comm. Artery(25.0%) and A-comm. Artery(15.0%) in that order. The number of ruptured aneurysms was in the order to MCA aneurysms. A-comm aneurysms, and P-comm aneurysms. The size of ruptured aneurysms was 6-10mm in 34 cases(64.2%). The unilateral distribution of aneurysms was 31 cases(57.4%) and the bilateral was 28 cases(42.6%). Depending on how many times the patient had the operation, these were 29(57.4%) cases of complete single operation, 17 cases(31.5%) of complete two-stage operation, and 8 cases(14.8%) of partial operation. Surgical outcome was good(GOS< or =4) in 42 cases(77.8%), and six patients(11.1%) expired. Based on the results of the above study we have concluded that initial Hunt-Hess grade has a close relationship with the outcome, but the operation type, the timing of operation, the number and distribution of aneurysms do not significantly effect the outcome.
Key Words: Multiple intracranial aneurysms(MIA); Hunt-hess grade; Complete single operation; Complete two-stage operation; Partial operation
