Abdominal Aortic Ultrasound
Medical necessity - Evaluate the aorta for presence or absence of aneurysm
Focused Question - Is there an abdominal aortic aneurysm?
1.) Obtain a video clip(s) of the entire abdominal aorta in the transverse plane from the xiphoid process to the umbilicus.
2.) Obtain static images in the transverse plane, measuring the anterior-posterior and width of the aorta in 3 zones:
Proximal (level of the celiac trunk)
Mid (below SMA, no specific landmarks)
Distal (level just before the bifurcation to the iliacs)
ABDOMINAL ANEURYSM IS DEFINED AS > 3CM.
***Exam is non-diagnostic for Abdominal Aortic Aneurysm if ANY segment of the abdominal aorta is not seen.
