CCI Peripheral Venous Evaluation 3

Question 1

In the context of peripheral venous evaluation, which condition is associated with May-Thurner syndrome?

Accepted Answer

Left common iliac vein compressed by the right common iliac artery

Answer

May-Thurner syndrome occurs when the right common iliac artery crosses and compresses the left common iliac vein, predisposing to left-sided DVT.

Question 2

Which B-mode gray-scale finding suggests CHRONIC rather than acute DVT?

Accepted Answer

Echogenic, retracted thrombus with partial recanalization

Answer

Chronic DVT typically appears echogenic (bright) and contracted, often with partial recanalization channels visible on color Doppler.

Question 3

A perforator vein is considered hemodynamically significant when outward (deep-to-superficial) reflux duration exceeds:

Accepted Answer

0.35 seconds

Answer

Perforator vein reflux is considered pathologic when outward flow lasts longer than 0.35 seconds after calf compression release.

Question 4

Which structure is identified at the confluence of the anterior tibial, posterior tibial, and peroneal veins?

Accepted Answer

Tibial-peroneal trunk

Answer

The tibial-peroneal trunk forms below the knee where the posterior tibial and peroneal veins join before entering the popliteal vein.

Question 5

When performing a venous duplex exam, the Valsalva maneuver is MOST useful for evaluating:

Accepted Answer

Competence of the saphenofemoral junction valve

Answer

The Valsalva maneuver increases intra-abdominal pressure and tests valve competence at the SFJ by provoking reflux if valves are incompetent.
