A portacaval shunt is a treatment for high blood pressure in the liver. A connection is made between the portal vein, which supplies 75% of the liver's blood, and the inferior vena cava, the vein that drains blood from the lower two-thirds of the body.
Causes, incidence, and risk factors
The most common causes of liver disease resulting in portal hypertension are cirrhosis caused by alcohol abuse and viral hepatitis (hepatitis B and C). Less common causes include diseases such as hemochromatosis, primary biliary cirrhosis, (PBC), and portal vein thrombosis.
