Abdominal Aortic Aneurysm Quiz- Case 13 – WFUMB

Question 1 of 2

1. Question
Clinical Description:

An elderly lady presents with dizziness and vomiting. The intern thinks there is a pulsatile mass. The patient is unsure of her past medical history (due to memory loss).

Describe the ultrasound findings?
- 1. Normal aorta.
- 2. AAA with heavy calcification.
- 3. AAA with dissection resulting a true and a false lumen.
- 4. AAA with endoluminal graft.
Correct

Within the AAA is the echogenic walls of the trouser leg graft. The longitudinal view in image 5 shows one of the ‘trouser legs’ but the other is out of plane

Incorrect

2. Question
Clinical Description:

An elderly lady presents with dizziness and vomiting. The intern thinks there is a pulsatile mass. The patient is unsure of her past medical history (due to memory loss)

Is there a graft leak?
- 1. Yes, colour flow is seen outside the graft.
- 2. No, there is no leak.
- 3. There is no evidence on these images, but it cannot be excluded.
- 4. Probably, the native aorta should have shrunk onto the graft with time.
Correct

Ultrasound may sometimes show a large graft leak, but this is beyond basic AAA scanning. Colour flow may be seen behind a reflective interface (such as a graft wall) due to mirror image artefact, so be careful not to overdiagnose. Once a graft is placed there will be thrombus between the graft and the wall of the aorta (but the AAA should stop growing).
