Biphasic portal vein Doppler trace

Case contributed by Dr Vikas Shah


Heart failure. Abnormal liver function tests.

Patient Data

Age: 50 years

Ultrasound of liver

There is a biphasic Doppler tracing of the portal vein. Other images showed an otherwise normal liver with no focal lesions or biliary dilatation, normal hepatic vein Doppler traces, and a normal sized spleen with no ascites.

Case Discussion

A biphasic Doppler trace of the portal vein in the presence of normal hepatic vein Doppler traces usually indicates raised right heart pressures secondary to tricuspid regurgitation. A normal portal vein Doppler trace should be monophasic with a little variation in maximum and minimum velocity, with no reversal of flow. In this particular case, when the line drops below the 0 cm/s level, there is reversal of flow.
