Can Subarachnoid Hemorrhage Recur?

Background and Purpose— Because intracranial aneurysms develop during life, patients with subarachnoid hemorrhage (SAH) and successfully occluded aneurysms are at risk for a recurrence.

What are the chances of having a second subarachnoid hemorrhage?

The cumulative recurrence rate of SAH, calculated using the Kaplan-Meier method, was 2.2% at 10 years and 9.0% at 20 years after the original treatment. Conclusions—The recurrence rate was considerably higher than the previously reported risk of SAH in the normal population, and the rate increased with time.

How do you prevent recurrent subarachnoid hemorrhage?

Effective measures for the secondary prevention of subarachnoid hemorrhage include life style modification, treatment of modifiable risk factors such as blood pressure control and avoidance, and enforcing the measures to prevent the complications.
