[Familial Osler's disease with lung involvement].

Hereditary hemorrhagic teleangiectasia is transmitted by an autosomal dominant character with typical vascular dysplasias in form of teleangiectasias and angiomas which occur on the skin, on the mucous membranes and also in nearly all organs of the body. More than 50% of patients with Osler's disease also have arteriovenous lung malformations. Therefore, pulmonary arteriovenous fistulas should be studied by x-rays for every member of a family suffering from this disease. To prove the suspicion of pulmonary arteriovenous fistula, the procedure of intravenous DSA should be used.
