Prevention and treatment of hepatic encephalopathy during the perioperative period of transjugular intrahepatic portosystemic shunt

Transjugular intrahepatic portosystemic shunt(TIPS)is an established procedure for treating the complications of portal hypertension in liver cirrhosis.While the pathogenesis of postoperative TIPS-related hepatic encephalopathy(HE)has yet to be fully understood,intraoperative portosystemic shunts may provide a pathological basis for the occurrence of postope-rative HE in patients with liver cirrhosis.Studies at home and abroad have expressed mixed opinions about TIPSrelated HE.This study presents a literature review on the risk factors for and prevention and treatment of perioperative TIPS-related HE in patients with liver cirrhosis,aiming to optimize the procedure and reduce the incidence of postoperative HE.
