TIPS may increase risk for which complication?

• A. Hepatic encephalopathy
• B. Portal hypertension
• C. Hepatorenal syndrome
• D. Spontaneous bacterial peritonitis

Answer: (A)

The key idea is that TIPS creates a direct portosystemic shunt, which lowers portal pressure but bypasses the liver’s detoxification of gut-derived substances. Because blood from the gut flows through the shunt without first passing through the liver, toxins like ammonia are less efficiently cleared. This increases the risk of hepatic encephalopathy, which can present as cognitive changes, confusion, or asterixis after the procedure. This is the most direct and well-established complication of TIPS. The procedure is designed to reduce portal hypertension, so it inherently decreases portal pressure rather than creating a new problem of portal hypertension. Spontaneous bacterial peritonitis isn’t a specific consequence of the shunt itself, and hepatorenal syndrome is a concern in advanced liver disease but is not the classic complication caused by bypassing hepatic filtration; in many cases, improving portal hemodynamics can even improve renal perfusion.
