An aortic aneurysm (say a-OR-tik AN-yuh-rih-zum) is a bulge in a section of the aorta, the body's main artery. The aorta carries oxygen-rich blood from the heart to the rest of the body. Because the section with the aneurysm is overstretched and weak, it can burst.
An aortic aneurysm is enlargement (dilation) of the aorta to greater than 1.5 times normal size.ortic aneurysms cause weakness in the wall of the aorta and increase the risk of aortic rupture. When rupture occurs, massive internal bleeding results, and, unless treated immediately, shock and death can occur.
