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 vessels 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 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."[1]

Aortic Aneurysm is when the aorta(biggest blood vessel in the body) grows very much. Every year, 200,000 people in the U.S. are diagnosed with an abdominal aortic aneurysm. It is when your aorta grows to be 1.5 times its normal size. It is usually enlarged at the bottom part of the aorta. This is a very dangerous disease and is life-threatening. Basically it grows so big that it weakens the walls and the protection that is around it. One way that it happens is through a rupture. This is when the actual aneurysm ruptures and bursts. There are two types of aortic aneurysm. The first is called the thoracic Aortic Aneurysm. This type of aortic aneurysm typically occurs in the chest. It occurs above the diaphragm. Both men and women are equally likely to have this problem. The next type is the abdominal aortic aneurysm. This is more likely than the thoratic one. While that one occurs in the thorax near the chest, this type occurs in the abdomen. They usually do not have any clear symptoms, so many people do not even know that they actually have this problem in the first place. They also grow very slowly. In a study, it was found that the survival rate for people who have this problem was about 87 percent. People who have undergone surgery have lived about an average of 5.4 years after. Usually this does not cause problems, but if it becomes ruptured it will cause problems. A big cause of this is smoking. Another big cause is your family’s history of heart problems. If your family has had a history of heart problems you will be more susceptible to this problem. Usually when doctors find this problem with the body, it is usually while scanning for other reasons. If it is ruptured and you feel it, you must go to a doctor immediately for a high chance of survival.
