Effective therapy for hepatic M. Osier with systemic hypercirculation by ligation of the hepatic artery and subsequent liver transplantation

Abstract

Abstract Hereditary hemorrhagic teleangiectasia, or M. Osier (Osler-Weber-Rendu disease), is an autosomal dominant, systemic fibrovascular dysplasia. This may lead to increased liver blood flow from arteriovenous fistulas. A 45-year-old woman with a known M. Osier was admitted for liver transplantation. On admission, exertional dyspnea was the predominant symptom. Radiological investigations revealed multiple intrahepatic arteriovenous fistulas and consecutive high-output heart failure. Laboratory findings revealed remarkably elevated bilirubin and alkaline phosphatase. To alleviate the high-output cardiac failure, the hepatic artery was ligated. Fourteen months later, the patient presented again with increased levels of bilirubin and recurrent bleeding episodes from esophageal varices grade IV. The patient underwent liver transplantation and post-transplant recovery was excellent. A hyperdynamic circulatory state due to a hepatic M. Osier has been treated in several cases by ligation or embolization of the hepatic artery. This procedure, however, is recommended only for patients with normal liver function and carries a considerable risk of bile duct necrosis.
