Overview

Brain Aneurysm

A brain aneurysm is a balloon or bubble-like growth that typically develops where a major artery branches into smaller arteries, often at the base of the brain.

Aneurysms have the potential to leak or rupture, causing bleeding into the brain or the surrounding area called the subarachnoid space. This subarachnoid hemorrhage can cause a stroke, leading to brain damage or death.

About 3 percent to 5 percent of the American population is affected by a brain aneurysm. The condition most commonly affects adults between the ages of 35 to 60 years old, although children can develop aneurysms. Aneurysms affect women more frequently than men. They can develop from continuous wear and tear on the artery walls and can be caused by factors such as genetics, injury or infection.

Our Approach to Brain Aneurysm

We help more than 300 patients with brain aneurysms each year – from common cases to the most complex. Our team offers advanced brain aneurysm care, including minimally invasive surgery to block the affected artery with platinum coils and bypass surgery for complex or giant aneurysms that can't be treated with conventional techniques. We were also among the first in the world to use 3D computer modeling for testing different approaches to operating on difficult-to-treat aneurysms.
