Portal venous flow is normally towards the liver (hepatopetal), with the normal main portal vein peak systolic velocities usually ranging between 20-40 cm/s.

In pathological situations, the flow velocity may decrease or even invert resulting in hepatofugal flow.

The flow waveform is usually smooth but with pathological situations can turn to pulsatile portal venous flow.
