[Pulmonary arteriovenous fistula in a newborn infant with hereditary telangiectasis].

A case of pulmonary arteriovenous fistula in a newborn baby suffering from hereditary teleangiectasis is described. 15% of patients with hereditary teleangiectasis develop pulmonary arteriovenous fistulas, most of which do not cause symptoms until adult life. Children with hereditary teleangiectasis should be followed regularly, because of the risk of developing vascular malformations, the most frequent locations being the nasal mucosa, the lungs and the gastrointestinal tract.
