An aortic aneurysm is a general term for an enlargement (dilation) of the aorta to greater than 1.5 times normal size.[1] While the cause of an aneurysm may be unknown, the result is weakness in the wall of the aorta at that location.

The aneurysm may occasionally cause pain, which is a sign of impending rupture. When rupture occurs, massive internal hemorrhage results, and, unless treated immediately, shock and death can occur within minutes.
