Fatal hypoxic hepatitis in a patient with hereditary hemorrhagic telangiectasia (Rendu-Osler-Weber's disease).

Hypoxic (ischemic) hepatitis generally requires the concurrence of an underlying condition which chronically exposes the liver to some degree of hypoxia (for example, congestive heart failure) combined with a triggering event (for example, arrhythmia) which further decreases the oxygen supply. We report a case of hypoxic hepatitis in which hereditary hemorrhagic telangiectasia (Rendu-Osler-Weber's disease) constituted this underlying condition and gastrointestinal hemorrhage was the triggering event. To our knowledge, this is the first reported case of hypoxic hepatitis in hereditary hemorrhagic telangiectasia with the exception of therapeutic ligation or embolization of the hepatic artery so as to decrease shunting of liver blood. Hemodynamic mechanisms are proposed to explain this particular outcome.
