Hepatic encephalopathy (HE) is a syndrome that occurs in patients with severe liver dysfunction or a portosystemic shunt. In patients with refractory HE caused by a portosystemic shunt, interventional closure of the shunt vessel is essential. Currently, transcatheter embolization is recognized as a less invasive and highly effective procedure, and it is considered as a first-choice method for the occlusion of shunt vessels. In this review, we discuss the role of a portosystemic shunt in the development of HE and describe the procedure and significance of transcatheter embolization of a portosystemic shunt.
