Can Transjugular Intrahepatic Portosystemic Shunt (TIPS) Procedures Lead to Hepatic Encephalopathy?
Hepatic encephalopathy (HE) is a common complication observed in individuals with decompensated cirrhosis. It is often initiated or worsened by the use of Transjugular Intrahepatic Portosystemic Shunt (TIPS) procedures. Managing HE in these patients remains a significant clinical challenge. Consequently, selecting appropriate candidates for TIPS treatment requires a meticulous evaluation of risk factors associated with the development of hepatic encephalopathy. This evaluation process is crucial for minimizing potential complications related to TIPS procedures, as of November 23, 2020.
How Does Portosystemic Shunt Cause Hepatic Encephalopathy?
Hepatic encephalopathy is a neuropsychiatric syndrome that arises as a result of a condition known as portosystemic shunt, where abnormal connections develop between the portal vein (which carries blood from the digestive organs to the liver) and systemic circulation. One of the primary factors contributing to the development of hepatic encephalopathy is the elevated presence of ammonia in the bloodstream. This condition can be effectively managed through a combination of primary and secondary prophylaxis, which aim to reduce ammonia levels and prevent its accumulation. In severe cases, when other treatments are ineffective, a liver transplant may be considered as a therapeutic option. As of July 31, 2023, this information is applicable.

Multiple factors have been proposed to contribute to the development of HE after TIPS placement. First, TIPS results in decreased first pass hepatic clearance of neurotoxins like ammonia but it also increases the splanchnic blood flow that may enhance the delivery of ammonia into the systemic circulation.Hepatic encephalopathy (HE) is a frequent complication of decompensated cirrhosis, eventually induced and/or aggravated by TIPS, that remains a clinical challenge especially in these patients. Therefore, patient selection for TIPS requires careful assessment of risk factors for HE.Portosystemic or hepatic encephalopathy is defined as a neuropsychiatric syndrome due to a portosystemic shunt. The causative factor is increased ammonia levels in the blood. Treatment involves primary and secondary prophylaxis and liver transplant.
