CCI Peripheral Venous Evaluation 5

Question 1

In duplex evaluation of suspected upper extremity DVT, which vein is MOST commonly affected by catheter-related thrombosis?

Accepted Answer

Subclavian or axillary vein

Answer

Catheter-related upper extremity DVT most commonly involves the subclavian or axillary vein due to central line placement routes.

Question 2

When evaluating calf veins, the paired posterior tibial veins travel adjacent to which artery?

Accepted Answer

Posterior tibial artery

Answer

The paired posterior tibial veins accompany the posterior tibial artery, running in the deep posterior compartment of the calf.

Question 3

Which maneuver is MOST effective for demonstrating reflux in the small saphenous vein (SSV) at the popliteal fossa?

Accepted Answer

Calf compression and release while patient stands

Answer

Calf compression with rapid release in the standing patient creates the pressure reversal needed to demonstrate SSV valve incompetence at the popliteal level.

Question 4

A patient with a history of DVT returns for follow-up. Duplex shows a recanalized femoral vein with echogenic walls and intraluminal webs. This BEST describes:

Accepted Answer

Chronic post-thrombotic changes

Answer

Recanalized vein with echogenic walls and synechiae (webs) are hallmark duplex findings of chronic post-thrombotic changes.

Question 5

The 'double channel' sign on duplex ultrasound in a venous segment MOST likely indicates:

Accepted Answer

Duplicated vein or partial recanalization of a thrombosed vein

Answer

A double-channel appearance can represent either a duplicated vein or partial recanalization of a previously thrombosed vessel with residual intraluminal material.
