General Discussion

Hereditary hemorrhagic telangiectasia (HHT or Osler-Weber-Rendu syndrome) is a rare inherited disorder characterized by malformations of various blood vessels (vascular dysplasia), usually resulting in excessive bleeding (hemorrhaging). Chronic nosebleeds are often the first apparent symptom associated with hereditary hemorrhagic telangiectasia. Malformation of various blood vessels may result in abnormalities affecting various organ systems of the body including the lungs, brain, and liver. Hereditary hemorrhagic telangiectasia is inherited as an autosomal dominant trait.
