Bulge in the aorta: The aorta is the largest blood vessel in the body, carrying blood from the heart - to the internal organs - and the legs. An aneurysm is a weakness in its wall. It bulges out and may rupture with time. Your doctor will tell you how big it is and if there are any other serious signs. If small enough, it may not need surgery, but most over 5 cm do.

Dilated aorta: Approx. 75% of aortic aneurysms are infrarenal. If the diameter of the aneurysm increases >= 0.5 cm/6mo. Period, early intervention advised. Once the aneurysm is 5cm or about twice the diameter of the non involved aorta, elective repair is advised. If 4cm dia and enlarging, repair advised to lower risk of death from exanguinating rupture. See your cardiovascular surgeon or vascular surgeon.
