Abdominal Aortic Aneurysm?

Myriad of possible pain complaints

  • abdominal pain
  • back pain,
  • flank pain,
  • groin pain can be from femoral nerve compression.


Low threshold for US, especially in patients that have prior history of AAA when coming in with those complaints.


How to do it?

-Supine, transverse plane.

-Start at xiphoid and follow aorta to umbilicus.

-Return to xiphoid and get a longitudinal view.

-IVC will be superior to pulsating aorta.


Normal aortic diameter typically < 2 cm.

risk of rupture:

  • <4 cm -> less than 2% risk per year
  • >7cm -> 20-50% risk per year
