Which duplex ultrasound finding is MOST diagnostic of acute deep vein thrombosis (DVT)?
Answer: Vein is non-compressible with direct probe pressure
Non-compressibility of the vein under direct transducer pressure is the primary criterion for diagnosing acute DVT.
Augmentation of venous flow during peripheral venous duplex examination is performed by:
Answer: Compressing the limb distal to the transducer
Distal limb compression augments venous flow toward the heart, confirming venous patency between the compression site and the transducer.
When evaluating the great saphenous vein (GSV), which anatomical landmark identifies its junction with the common femoral vein?
Answer: Saphenofemoral junction (SFJ) at the groin crease
The saphenofemoral junction (SFJ) is located near the groin crease where the GSV drains into the common femoral vein.
A patient presents with a warm, tender, palpable cord along the medial thigh. Duplex shows a thrombosed great saphenous vein. This condition is BEST classified as:
Answer: Superficial thrombophlebitis
Thrombosis of a superficial vein such as the GSV presenting with local inflammation is classified as superficial thrombophlebitis.
Which waveform characteristic on spectral Doppler indicates normal venous flow at the common femoral vein level?
Answer: Phasic variation with respiration
Normal common femoral vein flow is phasic, varying with the respiratory cycle due to changes in intrathoracic pressure.
During a lower extremity venous duplex exam, reflux in the great saphenous vein is defined as retrograde flow lasting longer than:
Answer: 0.5 seconds
Reflux in superficial veins (GSV, SSV) is defined as retrograde flow duration exceeding 0.5 seconds after augmentation release.
Which vein is evaluated at the popliteal fossa to assess for small saphenous vein (SSV) termination?
Answer: Saphenopopliteal junction (SPJ)
The saphenopopliteal junction (SPJ) is the site where the small saphenous vein drains into the popliteal vein, and its exact level is variable.
