Normal wedged hepatic 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 clini… Webwhat is homogeneous attenuation of the liver
