Bigger than normal: An ectatic abdominal aorta is one that is bigger than normal but not quite an aneurysm, which is defined as having a diameter that is 1.5X larger than that of a normal segment of aorta. A normal aorta for a man may be somewhere between 18-26 mm, though this is not hard and fast rule. There is general agreement that an aorta measuring 40 mm or greater would be considered an aneurysm, however.
