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.

Duodenal varices can develop in patients with portal hypertension secondary to liver cirrhosis. Although upper gastrointestinal bleeding is often severe and fatal, the definite treatment or guideline has not been established. Although endoscopy is the primary therapeutic modality, the use of radiologic interventions, such as transjugular intrahepatic portosystemic shunt, balloon or vascular plug-assisted retrograde transvenous obliteration, and percutaneous transhepatic variceal obliteration, can be considered alternative treatment methods for duodenal varices. Herein, we report a case of duodenal varix in a patient with poor hepatic functional reserve and vascular anatomy, which are contraindications for an occlusion balloon or a vascular plug, successfully treated with coil-assisted retrograde transvenous obliteration.
