In the abdominal aorta, the ectatic dilatation does not exceed how many centimeters?

Explanation:
Ectatic dilation means mild, diffuse enlargement of the artery that hasn’t become an aneurysm. The abdominal aorta normally measures about 2 cm in diameter. When it enlarges but stays at or below about 3 cm, it’s considered ectatic. Once the diameter exceeds 3 cm, it’s defined as an abdominal aortic aneurysm, with a higher risk of complications as it grows. So the maximal size for an ectactic abdominal aorta is 3.0 cm; anything larger crosses into aneurysm territory. For context, a 2.8 cm aorta is still ectatic, whereas 3.2 cm would be aneurysmal by standard definitions.
