Question 36#

Which of the following population groups is it appropriate to do a screening ultrasound of the abdomen for an AAA?

A. Men >60 years of age with a first-degree relative with an AAA

All of the above groups are appropriate to screen for an AAA. According to the appropriate use criteria published by intersocietal committee on peripheral vascular testing all of the groups listed are appropriate for AAA screening.

Question 37#

A 70-year-old man presents for follow-up in the clinic 1 month after undergoing right internal carotid artery stenting.

When should you get a post-procedure baseline carotid duplex ultrasound?

A. Four weeks after the intervention

Four weeks after the intervention. All patients should get a baseline carotid duplex ultrasound within 4 weeks after a carotid artery stenting or endarterectomy procedure.

Question 38#

A 70-year-old man presents for follow-up in the clinic 1 month after undergoing right internal carotid artery stenting

A baseline carotid duplex ultrasound demonstrates patency of the stent and no evidence of residual stenosis or restenosis of the right internal carotid artery after the procedure. One year after the carotid intervention, how often is it recommended to perform repeat carotid ultrasound surveillance in an asymptomatic patient?

A. Every 6 months

Every 12 months. It is recommended to repeat carotid duplex ultrasound every 12 months after the first year following carotid artery stenting to assess for evidence of in-stent restenosis.

Question 39#

A 65-year-old man presents for a routine physical examination. During the interview he complains about swelling behind his right knee. You order an ultrasound of the area (findings illustrated in figure below).

What is the most likely diagnosis?

A. Abscess

Popliteal artery aneurysm. Shown is a transverse and longitudinal image of a large popliteal artery aneurysm containing mural thrombus. The appearance is not suggestive of an abscess, Baker cyst, lymph node, or lipoma.

Question 40#

A 65-year-old man presents for a routine physical examination. During the interview he complains about swelling behind his right knee. You order an ultrasound of the area (findings illustrated in figure below).

What percentage of patients with a popliteal artery aneurysm have concomitant AAA?

A. 10%

50%. A large number of patients with a popliteal artery aneurysm will also have an AAA. Furthermore, 50% of patients with a popliteal artery aneurysm will have an aneurysm of the contralateral popliteal artery.
