Quick Q&A
Question #1
When measuring the abdominal aorta for aneurysm, where should the calipers be placed?
- A. Outside wall to inside wall
- B. Outside wall to outside wall
- C. Across the true lumen
- D. Inside wall to inside wall
Show Answer
The correct answer is B, outside wall to outside wall. You want to include the entire abdominal aortic aneurysm and should not underestimate its size.
Question #2
What is the most common type of AAA and space that it typically leaks into?
- A. Saccular, intraperitoneal
- B. Fusiform, intraperitoneal
- C. Saccular, retroperitoneal
- D. Fusiform, retroperitoneal
Show Answer
The correct answer is D. A fusiform aneurysm is the most common type. Rupture or leak is typically retroperitneal rather than intraperitoneal (which is why ultrasound is limited in its ability to determine whether rupture has occurred).
Question #3
The “seagull sign” shows which branches off the abdominal aorta?
- A. Common hepatic and splenic arteries
- B. Right and left renal arteries
- C. Left gastric and common hepatic arteries
- D. Superior and inferior mesenteric arteries
Show Answer
The correct answer is A. The seagull sign shows the two most prominent branches of the celiac artery. The left gastric is the third branch of the celiac but is not typically seen on ultrasound.
