Aneurysm description

An aneurysm is a fluid-filled pouch that forms as a result of a separation in the wall of a blood vessel. It usually occurs in a weak area of an artery’s wall where the blood pressure forces the weakened area to bulge outward. An aneurysm can rupture resulting in internal bleeding. A large rupture may be rapidly fatal. A small one, sometimes termed a leak, may produce warning symptoms that allow people to seek medical care.
