A common iliac artery diameter greater than which value indicates aneurysm formation?

Explanation:
Dilation beyond normal vessel size is what defines an aneurysm. For the common iliac artery, the diagnostic threshold is a diameter greater than 1.5 cm. In ultrasound, you measure the greatest arterial diameter in the transverse view, and when it exceeds 1.5 cm, it indicates an iliac artery aneurysm. Values around 1.0 cm are typically normal, while 2.0 cm or 2.5 cm are aneurysmal by implication, but the standard cut-off to diagnose an iliac aneurysm is 1.5 cm, making that the correct threshold.
