Thus, in people with advanced liver disease the shunting of portal blood away from hepatocytes is usually well tolerated. However, in some cases suddenly shunting portal blood flow away from the liver may result in acute liver failure secondary to hepatic ischemia. [6] Acute hepatic dysfunction after TIPS may require emergent closure of the shunt.
The presence of a shunt, a bypass of the liver, causes blood to flow directly to the heart. This blood is no longer filtered by the liver and reaches the systemic circulation, resulting in a number of symptoms and complications with effects on the cardiovascular, neurophysiological, gastro-intestinal, urinary and endocrinal systems.

The main treatment in those with refractory hepatic hydrothorax is the insertion of a transjugular intrahepatic portosystemic shunt (TIPS). TIPS decompresses the portal system, reducing portal venous pressure and fluid in the abdomen; it is estimated to work in 70-80% of cases. However, it does not improve the prognosis in those with end-stage ...
TIPS (transjugular intrahepatic portosystemic shunt) has replaced shunt surgery as it is less invasive and overcomes intrahepatic outflow obstruction by diverting hepatic and portal blood flow to the inferior vena cava. TIPS accomplishes the same goal as a surgical shunt but has a lower procedure-related mortality, a factor that has led to a ...
The first is the use of beta-blockers, which reduce portal pressures. Non-selective beta blockers (such as propranolol and nadolol) have been used to decrease the pressure of the portal vein in patients with esophageal varices, and have been shown to regress portal hypertensive gastropathy that has been worsened by medical treatment of varices.

A portacaval shunt (portal caval shunt) is a treatment for high blood pressure in the liver. A transjugular intrahepatic portosystemic shunt (TIPS) is an artificial channel within the liver that establishes communication between the inflow portal vein and the outflow hepatic vein. It is used to treat portal hypertension.
Fetor hepaticus or foetor hepaticus (Latin, "liver stench" ("fetid liver") [1] (see spelling differences), also known as breath of the dead or hepatic foetor, is a condition seen in portal hypertension where portosystemic shunting allows thiols to pass directly into the lungs.
Hepatic encephalopathy type B may arise in those who have undergone a TIPS procedure; in most cases this resolves spontaneously or with the medical treatments discussed below, but in a small proportion of about 5%, occlusion of the shunt is required to address the symptoms. [10] In hepatic encephalopathy type C, the identification and treatment ...
