Aneurysm: The difference between an aneurysm and a ectasia is one of degree. An ectasia is a mild enlargement of the aorta that is less then 1.5 times bigger than normal. Bigger than that is called an aneurysm. The normal size is 2cm so >3.0= aneurysm. More then 5.5 is considered large. The most important factor is very good BP control. Dr will be following this with ultrasounds every 6-12 mo. Good healh
