Normal wedged hepatic 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). Web23 de dez. de 2024 · A. Wedged hepatic vein pressure is usually normal in. presinusoidal portal hypertension. B. Wedged hepatic vein pressure is elevated in sinusoidal portal. hypertension. C.

Webpressure (wedged hepatic pressure) varied from 20.7 to 35.4 mm Hg. While the catheter was in an occluded position within the hepatic vein and the patients were undergoing splenectomy, the main trunk of the hepatic artery was clamped. The sinusoidal pressures then fell to levels that varied from 3.7 to 7.4 mm Hg but returned to previous levels when 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.

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…
