Endovascular management of a patient after SAH.

Treatment of acute aneurysmal subarachnoid hemorrhages consists of occluding the aneurysm to prevent rebleed, attempting to prevent vasospasm, and maintaining blood flow to the brain through vessels in vasospasm. Endovascular treatment has been shown to be as safe as, or safer, than surgical clipping for patients with SAH. Engineering solutions to our clinical problems continue to improve endovascular outcomes. This article reviews the current state of endovascular therapy.
