INDICATION

The indications for a CT of the abdominal aorta vary depending on an emergency versus outpatient presentation 1.

Generally, the abdominal aorta is included in standard trauma imaging (chest-abdomen-pelvis), which includes an arterial chest and portal venous abdomen. Thus, specific abdominal aortic imaging is only requested when high suspicion exists for a particular pathology.

Specific abdominal aortic pathologies that are investigated through imaging in an emergency setting include 1:

1. Abdominal aortic trauma.
2. Intramural haematoma.
3. Penetrating atherosclerotic ulcers.
4. Active haemorrhage.
5. Penetrating trauma.
6. Abdominal aortic aneurysm.

Outpatient environments focus on elective indications, including 2:

1. Assessment and follow-up aortic aneurysms.
2. Pre - and post-procedure evaluation of endovascular aneurysm repair.
