Portal venous pressure – Wikipedia

https://en.wikipedia.org/wiki/Portal_venous_pressure

WHVP is used to estimate the portal venous pressure by reflecting not the actual hepatic portal vein pressure but the hepatic sinusoidal pressure. It is determined by wedging a catheter in a hepatic vein, to occlude it, and then measuring the pressure of proximal static blood (which is reflective of pressure in the sinusoids). WHVP in fact slightly underestimates portal pressure due to sinusoidal equilibration in patients without cirrhosis, but the difference between the two is clinically insignificant. In patients with cirrhotic livers intersinusoidal communica…
