Rebleeding of Intracranial Aneurysm with SAH

ABSTRACT

The followings were evaluated as subjects of this study on 79 rebleeding cases of the 312 ruptures aneurysmal patients : incidence, time of rebleeding, location of rebleeding aneurysm, together with clinical grade and results of rebleeding. The incidence of rebleeding was 25.3% without prominent distinction between sexes. In the rebleeding rats by location, MCA aneurysm was found to be highest(30.8%) with no statistical significance. The 36.7% rebleeded in a week after initial bleeding, which indicates a daily average incidence of 5.3%. From one week on, the bleeding rate tapered off. Favorable risk patients showed a significantly higher rate(36.8%) compared with poor risk patients(6.7%). The mortality rate by rebleeding was 6.3%.
