Abstract
- In a consecutive series of 100 patients with ruptured saccular aneurysm, 69% of them under-went surgery and 31% did not. Of those who did not have surgery, half refused surgery and the other half had too high risk factors to be operated. Sixty seven percent of surgical cases under-went direct neck clipping, while 14% of them had wrapping or proximal clipping of anterior cerebral artery and 19% of them, carotid ligation. The mortality rate of non-microsurgery group was 14% and that of microsurgery group was 6%. The morbidity rate of non-microsurgery group was 19% and that of microsurgery group was 11%. The use of operating microscope brought about the significant reduction in the incidence of surgical mortality and morbidity.
