A brain aneurysm, also known as a cerebral aneurysm, is a weak, bulging segment of a blood vessel in the brain. Left untreated, a brain aneurysm can burst and bleed into the brain.
A brain aneurysm rupture is a medical emergency. Almost half of people who experience a brain aneurysm rupture do not survive it. About 20 to 35 percent of people have moderate to severe brain damage after a rupture.
At Dignity Health, our talented doctors provide highly skilled emergency treatment for brain aneurysm in Arizona. Use our online InQuicker™ tool to select your estimated arrival time to your nearest Dignity Health emergency room location.

Not all brain aneurysms require treatment. Treatment options depend upon on the size, type, and location of your aneurysm. If your brain aneurysm is small and not causing problems, your doctor may recommend monitoring it for changes. In other cases, your doctor may recommend medication or surgery to prevent the aneurysm from rupturing. Your doctor will assess your unique experience to develop a personalized treatment plan.
When an aneurysm ruptures or bursts, it can bleed into the brain causing a hemorrhagic stroke. It can also bleed into the space around the brain causing a subarachnoid hemorrhage. Either of these are serious conditions that can lead to permanent brain or nerve damage or death. Your treatment plan will aim to stop bleeding into the brain and prevent further brain damage.
