Stent-graft to treat intrahepatic portosystemic venous shunt causing encephalopathy.
Spontaneous intrahepatic portosystemic venous shunts (IPSVS) are rare, and angiographic intervention to treat IPSVS has been limited. To our knowledge, we present the first case of an IPSVS between the right portal vein and inferior vena cava accompanied by intractable encephalopathy that was successfully obliterated using a stent-graft deployed in the inferior vena cava to disconnect the portal and systemic venous circulation. Our patient, a 58-year-old woman, has shown no evidence of recurrent portosystemic venous shunt or encephalopathy for 30 months. We believe this intervention to be a useful alternative therapy for this type of shunt.
