Successful portal-systemic shunt occlusion with balloon-occluded retrograde transvenous obliteration for portosystemic encephalopathy without liver cirrhosis.
A 68-year-old woman was admitted to the authors' hospital for hepatic encephalopathy. Her laboratory data and computed tomography findings were not suggestive of liver cirrhosis. Superior mesenteric angiography revealed an extrahepatic portal-systemic shunt with a main cause of hepatic encephalopathy. Despite treatment with branched-chain amino acid, lactulose, and kanamycin, hyperammonemia was prolonged, and the portal-systemic shunt was therefore treated with balloon-occluded retrograde transvenous obliteration. After the procedure, hyperammonemia was improved, and there were no signs of recurrent portal-systemic encephalopathy.
