[Rendu-Osler-Weber syndrome--a complex systemic disease]

Hereditary hemorrhagic teleangiectasia (HHT or Rendu-Osler-Weber Syndrome) is an inherited autosomal dominant disorder of the vascular connective tissue. The resulting vascular malformations can occur in virtually any organ. Nosebleeds can massively impact on the quality of life of those afflicted. However, visceral manifestations are likely to be more serious, and may be comparable with a "ticking time bomb". Most commonly affected are the vascular systems of the lungs, liver, brain and gastrointestinal tract. Screening is recommended--at least with regard to the lungs. Difficult constellations of this complex condition may be successfully managed by an interdisciplinary approach.
