Brain aneurysm repair is a surgical procedure to correct an aneurysm, a weak area in the wall of a blood vessel that causes the blood vessel to bulge or balloon out. It can leak blood and cause a stroke or bleeding into an area around the brain (also called a subarachnoid hemorrhage).
Surgery on any one area of the brain may cause problems with speech, memory, muscle weakness, balance, vision, coordination, and other functions. These problems may be mild or severe, and they may last a short while or they may not go away.
You will usually be asked not to eat or drink anything for 8 hours before the surgery.
Take the drugs your doctor told you to take with a small sip of water.
Your doctor or nurse will tell you when to arrive.
After the Procedure
A hospital stay for endovascular repair of an aneurysm may be as short as 1 to 2 days if there was no bleeding beforehand.
The hospital stay after craniotomy and aneurysm clipping is usually 4 to 6 days. When bleeding or other complications occur before or during surgery, the hospital stay can be 1 to 2 weeks, or more.
You will probably have an x-ray test of the blood vessels in the brain (angiogram) before you are sent home.
Ask your doctor if it will be safe for you to have MRI scans in the future.
After successful surgical treatment for a bleeding aneurysm, it is uncommon for it to bleed again.
The outlook also depends on any brain damage that occurred from bleeding before, during, or after the surgery.
Most of the time, open surgery or endovascular repair is more likely to prevent a brain aneurysm that has not caused symptoms from becoming larger and breaking open.
