An Abdominal Aortic Aneurysm is a dilation of, or swollen abdominal aorta, a great vessel that supplies the lower body with blood. Folks who are obese, have high cholesterol (including plaquing of the arteries / atherosclerosis, and "harderning of the arteries" or arteriosclerosis) , and are elderly, are the risk group that one primarily looks at, as possibly having this problem. Often, these "Tripe As" are picked up on a lateral lumbar x-ray. When the Anterior to Posterior dimension of the abdominal aorta reaches or exceeds two (2) inches, there is considerable concern for a possible spontaneous rupture, or if the patient is in a auto accident, a rupture can also occur. Statistically, folks who sustain a rupture of the abdominal aorta, are dead within thirty minutes, unless they happen to be near to a surgical center and are able to have surgical intervention. If one has a one to one and a half (A-P diameter) AAA, it is a good idea to monitor it to see if the size is growing significantly, in order to be able to intervene before a spontaneous rupture occurs. Rupture of an AAA is extremely serious.
