Treatment & Prevention for a Ruptured Brain Aneurysm

A ruptured brain aneurysm needs emergency treatment. It can bleed into the space around the brain (subarachnoid hemorrhage) or the brain itself (hemorrhagic stroke). These serious conditions can cause permanent nerve or brain damage, or possibly death. Treatment aims to stop bleeding into the brain and prevent further brain damage.

If your brain aneurysm hasn’t ruptured and isn’t causing problems, your doctor may recommend holding off treatment and monitoring the aneurysm for changes.

To prevent an aneurysm from rupturing, your doctor may recommend surgery or medication. Your health care team with work with you to create a treatment strategy that best fits your needs and keeps you healthy. Treatment and prevention options for your aneurysm depend on its size, type, and location.
