[Liver failure caused by recurrent biliary bleeding associated with Osler's disease: a case report]

A 34-year-old female patient with epigastric pain was admitted to our hospital. She reported an underlying condition of Rendu-Osler-Weber disease and a history of coil embolization for pulmonary arteriovenous fistula. A blood test revealed high hepatobiliary enzyme levels. An abdominal contrast-enhanced computed tomography revealed numerous arterioportal and arteriovenous shunts in the liver and a high-density area in the bile duct, which was diagnosed as biliary bleeding. She underwent transpapillary biliary drainage by endoscopic retrograde cholangiopancreatography, but recurrent biliary bleeding caused cholangitis, which was complicated by multiple liver abscesses. She was awaiting her turn for liver transplantation from brain-dead donors, but the liver abscesses were difficult to improve. Further, liver failure, septic pulmonary embolism, and disseminated intravascular coagulation were complicated. Thus, recurrent further biliary bleeding resulted in hemorrhagic shock, which required frequent blood transfusions. Furthermore, the continuous abscess to the intrahepatic bile duct in the anterior superior segment penetrated her diaphragm, causing hemothorax and eventually, death. Establishing progressive treatment, including liver transplantation, is considered necessary for this intractable disease.
