In brief: 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.

An aneurysm is like a balloon in the artery. The major risk is for it to pop or rupture. We recommend fixing the aneurysm when the risk of the surgery is lower than the risk of the aneurysm rupturing. Small aneurysms are at low risk of rupturing, and are typically followed with imaging. Larger aneurysms are repaired- either open or endovascularly.

In brief: 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.

Be aware that AAA (Abdominal Aortic Aneurysm) has a familial predisposition. If your parents or siblings have been diagnosed with a AAA, you should be checked with an ultrasound to screen for an aneurysm. In my practice, I have found it remarkable how often AAA are found in multiple family members.
