Q; After successful completion of Transjugular Intrahepatic Porto-systemic Shunt (TIPS) for variceal bleeding - hepatic encephalopathy __________ ?

A) tends to get better

B) tends to get worse

C) It has nothing to do with TIPS



Answer is B

Hepatic encephalopathy tends to get worse after successful completion of TIPS as due to shunting, blood flow to the liver is reduced, which might result in increase toxic substances reaching the brain without being metabolized first by the liver. It can be treated medically such as diet, lactulose or by narrowing of the shunt by insertion of a reducing stent.
