Abstract
A case of Rendu-Osler-Weber disease in a young girl is presented. The autosomial dominant disease with variable penetrance is characterized by multiple telengiactasic lesions and arteriovenous malformations (fistulas) involving skin, mucous membrane, liver, lung and brain. The patient, with several pulmonary and cerebral arteriovenous fistulas and clinical signs of cronic hypoxia, was treated by transcatheter embolization of larger pulmonary fistulas with ballons and tungesteno spirals, with good result.
