With a brain aneurysm, you may require an intracranial bypass to route blood around a blocked blood vessel. This restores blood flow to the brain.
The surgical procedure involves a surgeon making a small hole to expose the area that needs to be treated. A healthy blood vessel from an area outside your brain will be connected to a blood vessel inside your brain. In some cases, the surgeon may take a vein or artery from your arm or leg to use in this procedure to help restore healthy blood flow to your brain.
The first reported intracranial bypass surgery in the United States was performed at Lenox Hill Hospital, part of Northwell Health.
