Abdominal Aorta Aneurysms (AAA). Ultrasound has been shown to be accurate in identifying both aneurysmal and normal aortas. Training will include complete evaluation of the abdominal aorta from diaphragm to its bifurcation for recognition of aneurysm. In the event of identification of an AAA, you will need to assess for free intraperitoneal fluid suggestive of rupture.
