Pressure range of portal hypertension?

summary

Many people don't know the normal diameter of the portal vein? What are the diseases of portal vein? So this paper makes a detailed introduction. Under normal circumstances, the inner diameter of the main portal vein of the human liver is 0.6 to 1.0 cm, and the maximum can reach 1.5 cm. Under normal circumstances, when people inhale deeply, the inner diameter of the portal vein will expand. This is because the diaphragm compresses the liver and the blood flow out of the liver is blocked, so the inner diameter of the portal vein will expand. This is normal.

Pressure range of portal hypertension?

1. In other words, if the inner diameter of the portal vein is between 0.6 cm and 1.5 cm, it can be regarded as normal, but if it is lower or higher than this range, it will be abnormal, and corresponding portal vein diseases will also appear, such as portal vein thrombosis, and portal vein congenital abnormalities.

2. Portal vein thrombosis may occur at any stage of the portal vein. In most cases, the cause of the disease is not clear, which may be related to systemic or local infection. 10% of the cases are caused by liver cirrhosis, and may also be caused by portal vein congestion caused by pregnancy.

3. Congenital abnormalities of portal vein, which is mainly caused by abnormal atresia of yolk vein and ventral anastomotic branch, will appear in infants after birth multicavity, this is due to the infant after birth thrombosis and then recanalization, the final result of the formation of a new lumen.

matters needing attention

If it is acute portal vein thrombosis patients, because the blood clot has been formed, at this time through anticoagulant treatment has no effect, but this drug can prevent the spread of blood clot, if it is chronic patients can take conservative treatment.
