What is the normal portal venous pressure range?

The portal venous pressure of the liver usually refers to the pressure within the hepatic portal vein. The normal range for hepatic portal venous pressure corresponds to the normal diameter of the portal vein, which generally falls between 0.6 cm and 1.3 cm.

The diameter of the portal vein may be slightly influenced during respiration but typically does not exceed 1.3 cm. The normal portal venous pressure ranges from 1.27 to 2.35 kPa. When the pressure exceeds this normal range, patients may develop symptoms such as splenomegaly, hypersplenism, ascites, or hematemesis. In severe cases, it can pose life-threatening risks. Therefore, if elevated hepatic portal venous pressure is suspected, timely medical evaluation at a hospital is necessary, including ultrasound, angiography, abdominal paracentesis, and complete blood count tests, to determine the underlying cause and select an appropriate treatment approach.

In daily life, patients are advised to follow a diet low in fat and rich in protein and vitamins. They should also monitor their health closely and seek prompt medical attention if any discomfort or symptoms arise.
