SVU Professional Performance DVD Series

Renal Artery and Mesenteric/Splanchnic Artery Duplex Imaging Examinations

This test is based on the SVU Professional Performance DVD Series: Renal Artery and Mesenteric/Splanchnic Artery Duplex Imaging Examinations

Before you take this test plese review the material on the DVD. If you do not have a copy of the DVD please order one at svunet.org/publications/DVDs.

Each SVU Professional Performance DVD is approved for 1 SVU-CME.

This DVDs are based in part on SVU’s Professional Performance Guidelines for vascular ultrasound studies. They extend and refine those general Guidelines, which reflect behavior and performance levels expected in clinical practice, to better reflect the day-to-day practice of vascular technology.

The SVU Vascular Technology Professional Performance Guidelines represent the minimal essential elements of performance as recommended by SVU. They are not designed to replace internally generated, laboratory specific protocols, but to serve as a basis for developing or updating the procedure(s) described.

Which waveform below demonstrates a tardus parvus appearance?
When performing Doppler analysis of the segmental renal arteries, the Doppler angle should be:
1. Less than 30 degrees
2. 60 degrees
3. 45-60 degrees
4. 90 degrees
Which of the following is considered to be an abnormal RAR?
1. 2
2. 2.5
3. 3
4. 4
Which of the following most accurately describes the normal course of the left renal vein?
1. Retroaortic
2. Between the SMA and splenic vein
3. Underneath the IVC
4. Anterior to the aorta and posterior to the SMA
Reversed flow in the Gastroduodenal artery is associated with occlusion of which vessel?
1. SMA
2. IMA
3. Celiac
4. Splenic
In the fasting state, the inferior mesenteric artery:
1. Cannot be examined with Doppler
2. Shows a high resistance waveform
3. Shows a low resistance waveform
4. None of the above
A false negative indirect renal Doppler study is most likely to occur due to which of the following:
1. Patient was not NPO
2. RI is above 0.70
3. RI is below 0.70
4. Aortic aneurysm
The angiographic appearance termed “string of beads” is associated with:
1. High grade renal artery stenosis
2. Renal artery dissection
3. Renal artery aneurysm
4. Renal artery fibromuscular dysplasia
Which of the following is most likely to result in a false negative study for renal artery stenosis using the direct method?
1. Stenosis in an undetected accessory renal artery
2. RI above 0.70
3. RI below 0.70
4. Aortic aneurysm
An accurate description of the RAR is:
1. Maximum renal artery velocity divided by aortic velocity obtained at the level of the aortic bifurcation
2. Segmental renal artery velocity divided by aortic velocity obtained at the level of the aortic bifurcation
3. Maximum renal artery velocity divided by aortic velocity obtained at the level of the renal arteries
4. Minimum renal artery velocity divided by aortic velocity obtained at the level of the aortic bifurcation
