The CEAP classification system for chronic venous disease uses which component to categorize clinical severity?
Answer: C — Clinical signs (C0–C6)
The 'C' component of CEAP classifies clinical severity from C0 (no signs) through C6 (active venous ulcer).
During a lower extremity venous reflux study, the patient should be positioned:
Answer: Standing or reverse Trendelenburg to maximize venous filling
Standing or reverse Trendelenburg positioning distends the veins with blood, making reflux easier to provoke and measure.
Reflux in the deep venous system (femoral and popliteal veins) is defined as retrograde flow lasting longer than:
Answer: 1.0 second
Deep vein reflux is defined as retrograde flow exceeding 1.0 second, a longer threshold than for superficial or perforator veins.
A patient with post-thrombotic syndrome (PTS) would MOST likely demonstrate which duplex finding?
Answer: Chronic thrombus with recanalization and deep venous reflux
PTS results from prior DVT causing valve destruction, leading to recanalized but incompetent deep veins with chronic reflux.
When color Doppler shows a 'mosaic' pattern within a venous segment, this MOST likely represents:
Answer: Turbulent flow due to partial obstruction or stenosis
A mosaic color pattern indicates flow turbulence, which can occur with partial venous obstruction, stenosis, or extrinsic compression.
The Giacomini vein is a venous variant BEST described as:
Answer: A thigh extension of the small saphenous vein connecting to the great saphenous vein
The Giacomini vein is a communicating vein that extends the SSV cranially in the posteromedial thigh to connect with the GSV.
Which sonographic sign is used to detect a Baker's cyst (popliteal cyst) that may mimic DVT symptoms?
Answer: Anechoic or hypoechoic fluid-filled structure posterior to the knee communicating with the joint
A Baker's cyst appears as a fluid-filled structure between the medial head of the gastrocnemius and semimembranosus, often communicating with the knee joint.
