Intrahepatic portosystemic venous shunt (IPSVS) is a rare vascular abnormality that involves abnormal communication between the intrahepatic portal vein and systemic veins, such as the hepatic vein or inferior vena cava. Patients with IPSVS are typically asymptomatic, and IPSVS is incidentally discovered via imaging while evaluating other diseases. However, endovascular closure of the shunt should be considered in symptomatic patients with a high-flow shunt. This report presents a patient with congenital IPSVS with sudden onset hepatic encephalopathy treated using percutaneous transhepatic embolization.
