RVT Peripheral Venous Testing 3

Question 1

In the CEAP classification for chronic venous disease, what does a classification of C3 indicate?

Accepted Answer

Edema without skin changes

Answer

C3 in the CEAP classification denotes edema of venous origin without skin changes.

Question 2

During upper extremity venous duplex imaging, which vein is most commonly involved in effort-related (Paget-Schroetter) thrombosis?

Accepted Answer

Subclavian vein

Answer

Paget-Schroetter syndrome involves thrombosis of the axillo-subclavian vein, typically related to repetitive arm activity.

Question 3

What probe frequency range is most appropriate for imaging superficial veins such as the great saphenous vein?

Accepted Answer

7-15 MHz

Answer

High-frequency transducers (7-15 MHz) provide optimal spatial resolution for superficial structures like the great saphenous vein.

Question 4

A patient with suspected May-Thurner syndrome would most likely present with DVT in which vessel?

Accepted Answer

Left common iliac vein

Answer

May-Thurner syndrome involves compression of the left common iliac vein by the overlying right common iliac artery, predisposing to left-sided DVT.

Question 5

Which finding on duplex ultrasound best differentiates a chronic from an acute DVT?

Accepted Answer

Hyperechoic, echogenic thrombus with vein wall thickening and partial recanalization

Answer

Chronic DVT typically appears as echogenic (bright) thrombus with vein wall thickening, irregularity, and partial recanalization of the lumen.
