다발성 뇌동맥류 환자의 수술적 치료 결과에 대한 고찰 = Overview of Surgical Result of Multiple Intracranial Aneurysmal Patients

다국어 초록 (Multilingual 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 aneurysmal 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 of MCA aneurysms A-comm aneurysms, and F-comm aneurysms.
The size of ruptured aneurysms was 6-10mm if 34 cases(64.2%). The unilateral distribution of aneurysms was 31 cases(57.4%) and the bilateral was f8 cases(42.6%).
Depending on how many times the patient had the operation, there 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≤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.
