Pulsatile portal venous flow

Pulsatile portal venous flow pattern can result from both physiological and pathological causes.

Usually, mild pulsatility or in rare situations even marked pulsatility has been described, particularly in thin subjects with a venous pulsatility index of >0.5 with an inverse correlation to body mass. Decreased pulsatility has been observed when the patient is sitting and during deep inspiration, and in obese subjects. It has been suggested that abdominal pressure is the common factor affecting portal vein pulsatility in these subjects 1.  

In pathological situations, pulsatile flow in the portal vein has been found in patients with a few conditions that have been listed below 2,4. To differentiate among the first three causes, which are the more common, the cojoined assessment of the hepatic veins is very useful.
