Answer

Wedged hepatic venous pressure (WHVP) is measured by inflating a balloon at the catheter tip, thus occluding a hepatic vein branch. Measurement of the WHVP provides a close approximation of portal pressure. The WHVP actually is slightly lower than the portal pressure because of some dissipation of pressure in the sinusoidal bed. The WHVP and portal pressure are elevated in patients with sinusoidal portal hypertension, as is observed in cirrhosis.
