Fifty-three of 236 consecutive patients (22.5%) who suffered a proved aneurysmal subarachnoid hemorrhage and who were admitted within 72 hours after subarachnoid hemorrhage to a primary emergency hospital had at least one rebleed within 6 months after the primary bleed. Two patients later had a rebleed within a mean of 3 years follow-up. ⋯ The rebleed mortality rate was 74%, and only 19% of patients with a rebleed had a good outcome. The grade on admission, age, and sex do not affect the incidence nor the time of rebleeding.
