Portal venous pressure refers to the pressure within the portal vein and its tributaries, which carry blood from the gastrointestinal tract and spleen to the liver. This pressure is an important aspect of the hepatic vascular system and is typically measured in millimeters of mercury (mmHg). Normal portal venous pressure is usually around 5 to 10 mmHg.
