The … 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…

WebHepatic vein pressure measurement, recorded with a catheter which lies in an unobstructed major hepatic vein branch, is directly related to the measured portal vein pressure.

Web30 de jan. de 2004 · By threading a small catheter into a hepatic vein until it cannot be advanced further, a “wedged” hepatic venous pressure is obtained. As the hepatic vein is occluded, a continuous column of fluid between the catheter and the sinusoid is formed, resulting in a pressure reading that is equal to the sinusoidal pressure (Fig. 1).

Webpressure (wedged hepatic pressure) varied from 20.7 to 35.4 mm Hg.
