An aneurysm is an abnormal bulge or ballooning in the wall of a blood vessel.
Aneurysms often occur in the aorta, brain, back of the knee, intestine, or spleen.
Aneurysms often have no symptoms until they rupture. A ruptured aneurysm can result in internal bleeding, stroke, and can sometimes be fatal.
Treatment varies from watchful waiting to emergency surgery. The choice depends on the location, size, and condition of the aneurysm.
