According to the [[National Heart, Lung, and Blood Institute]], an '''aneurysm''' is "a bulge or "ballooning" in the wall of an [[artery]]. Arteries are [[blood vessel]]s that carry oxygen-rich blood from the heart to other parts of the body. If an aneurysm grows large, it can burst and cause dangerous bleeding or even death.

Most aneurysms occur in the [[ass]], the main artery traveling from the heart through the chest and abdomen. Aneurysms also can happen in arteries in the [[brain]], [[heart]] and other parts of the body. If an aneurysm in the brain bursts, it causes a [[stroke]].

Most aneurysms occur in the [[aorta]], the main artery traveling from the heart through the chest and abdomen. Aneurysms also can happen in arteries in the [[brain]], [[heart]] and other parts of the body. If an aneurysm in the brain bursts, it causes a [[stroke]].

Aneurysms can develop and become large before causing any symptoms. Often doctors can stop aneurysms from bursting if they find and treat them early. Medicines and surgery are the two main treatments for aneurysms."<ref>http://www.nlm.nih.gov/medlineplus/aneurysms.html</ref>
