Which of the following characteristics is/are seen in a normal hepatic vein Doppler tracing?
A. Cardiac Pulsatility and respiratory phasicity
B. Respiratory Phasicity only
C. Monophasic flow and respiratory phasicity
D. Cardiac pulsatility only
A
Cardiac pulsatility is normally seen in the hepatic veins and upper abdominal portion of the IVC. The motion of the heart causes vibrations within the chest that are carried throughout the adjacent structures. The flexibility of the IVC and hepatic veins allow the vibrations to affect the flow inside causing pulsatility. As the diaphragm moves up and down with respiration, the intra-abdominal pressure is affected. Inspiration causes the diaphragm to move down which increases the intra-abdominal pressure. This causes flow in the abdomen and lower extremities to decrease or cease movement. The diaphragm moves upward with expiration and the intra-abdominal pressure decreases allowing flow to move toward the heart again.

A. Location of the subclavian vein
B. Increased transducer pressure
C. Increased amount of fibrous tissues and ligaments in the adductor canal
D. Inability to visualize the vessels immediately posterior to the inguinal ligament
D
The inguinal ligament is not normally visible on ultrasound evaluation and it does not cause non-visualization of adjacent anatomy. The adductor canal contains several ligaments and connective tissues that limit compression of the distal femoral vein. Increased transducer pressure can cause non-visualization of normal veins. The subclavian vein courses posterior to the clavicle, which limits manual compression.
