Transjugular intrahepatic portosystemic stent shunt.
The transjugular intrahepatic portosystemic stent shunt (TIPSS) is essentially a side-to-side portocaval shunt performed by interventional radiological methods which connects the hepatic vein to the portal vein via the liver parenchyma. It can be performed successfully in 85% to 95% patients. The procedure mortality is low (1% to 2%) and is mainly from intraperitoneal bleeding. Major indications for TIPSS are in patients in whom sclerotherapy for bleeding varices has failed, those who have recurrent variceal haemorrhage after sclerotherapy or band ligation and in patients with refractory ascites, hypersplenism and portal gastropathy. It has also been used in some patients with the Budd-Chiari syndrome, portal vein thrombosis and cirrhotic hydrothorax. TIPSS is followed by variceal rebleeding and encephalopathy in about 10% to 20% of cases, deterioration in liver function in about 25% to 35% and shunt dysfunction in 15% to 60%. Further research should be directed at developing newer types of stents to prevent shunt dysfunction.
