A shunt that is inserted through the skin, jugular vein, and liver and then into the portal venous system to manage complications of portal hypertension, such as bleeding caused by esophageal varices or uncontrollable ascites. The shunt decreases pressure within the portal venous circulation (e.g., in patients with cirrhosis), bypassing the liver and allowing portal blood to flow directly into the vena cava. A common complication of the procedure is altered mental status, since blood that was previously detoxified by the liver is directed around it.
