CCI Peripheral Venous Evaluation 4

Question 1

The CEAP classification system for chronic venous disease uses which component to categorize clinical severity?

Accepted Answer

C — Clinical signs (C0–C6)

Answer

The 'C' component of CEAP classifies clinical severity from C0 (no signs) through C6 (active venous ulcer).

Question 2

During a lower extremity venous reflux study, the patient should be positioned:

Accepted Answer

Standing or reverse Trendelenburg to maximize venous filling

Answer

Standing or reverse Trendelenburg positioning distends the veins with blood, making reflux easier to provoke and measure.

Question 3

Reflux in the deep venous system (femoral and popliteal veins) is defined as retrograde flow lasting longer than:

Accepted Answer

1.0 second

Answer

Deep vein reflux is defined as retrograde flow exceeding 1.0 second, a longer threshold than for superficial or perforator veins.

Question 4

A patient with post-thrombotic syndrome (PTS) would MOST likely demonstrate which duplex finding?

Accepted Answer

Chronic thrombus with recanalization and deep venous reflux

Answer

PTS results from prior DVT causing valve destruction, leading to recanalized but incompetent deep veins with chronic reflux.

Question 5

When color Doppler shows a 'mosaic' pattern within a venous segment, this MOST likely represents:

Accepted Answer

Turbulent flow due to partial obstruction or stenosis

Answer

A mosaic color pattern indicates flow turbulence, which can occur with partial venous obstruction, stenosis, or extrinsic compression.
