Brain Surgery for Aneurysm

A brain aneurysm is the enlargement of a blood vessel in the brain. It can cause bleeding in the brain from the vessel leaking or breaking. Surgery involves closing the aneurysm with a small metal clip. A less invasive method is the insertion of a catheter. The catheter is usually inserted in an artery of the groin and moved through the body to the aneurysm. A guide wire is used to push a soft wire through the catheter into the aneurysm. The wire stops blood flow to the aneurysm and causes blood clotting. The clots close off the aneurysm from the artery.
