The use of TIPS in chronic liver disease.
The development of cirrhosis and portal hypertension in the natural history of chronic liver disease is associated with many complications. A transjugular intrahepatic portosystemic stent shunt (TIPS) is a metal prosthesis that has been shown to be very effective in lowering sinusoidal portal pressure, and therefore is effective in the management of complications of cirrhosis, especially those related to portal hypertensive bleeding and sodium and water retention. In patients with acute variceal bleeding not responding to pharmacologic and endoscopic treatments, a reduction of the hepatic venous pressure gradient to < 12 mmHg or by > 20% with TIPS has been shown to be effective in controlling the acute bleed and in preventing rebleeding. For stable patients whose acute variceal bleed is controlled, TIPS is equal to combined beta-blocker and band ligation in the prevention of recurrent variceal bleed. TIPS is also more effective than large volume paracentesis in the control of refractory ascites, and may confer a survival advantage over repeated large volume paracentesis. TIPS has also been used in the management of other complications related to portal hypertension including ectopic varices, hepatic hydrothorax, and hepatorenal syndrome with some success, but experience is still rather limited. Miscellaneous uses include treatment of Budd Chiari Syndrome, portal hypertensive gastropathy and hepatopulmonary syndrome. Careful patient selection is vital to a successful outcome, as patients with severe liver dysfunction tend to die post-TIPS despite a functioning shunt. All patients who require a TIPS for treatment of complications of cirrhosis should be referred for consideration of liver transplant.
