An<unk>  is a localized bulge or balloon in the wall of an artery, or in most cases in the aorta (the major blood vessel that supplies blood to the body).<unk> s occur in the part of the aorta running through the abdomen, if the<unk>  ruptures it can cause life-threatening bleeding. 
Because<unk> s can develop and become large before causing any symptoms, it is important to look for them in people who are at high risk. Most small<unk> s do not rupture, but the large<unk> s have a higher risk of a rupture. Ultrasound screening for<unk> s is recommended for men who have ever smoked and are between the ages of 65 and 75. Medications and surgery are the two main treatments for<unk> s.
