Pulsatile portal venous flow

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

Usually mild pulsatility or in rare situations even marked pulsatilility 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 predominantly been found in patients with severe right heart failure and its causes including tricuspid regurgitation 2.
