[Expectoration of embolization coils 15 years after embolization of pulmonary arteriovenous malformations in a patient with hereditary hemorrhagic telangiectasia].

Hereditary hemorrhagic telangiectasia can manifest itself with pulmonary arteriovenous malformations (pavm). A transcatheter coil embolization should be made to avoid complications and to close off relevant arteriovenous shunts. We report on a patient with expectoration of embolization coils 15 years after embolotherapy. In case of hemoptysis following embolotherapy with coils, even years after their placement one should consider coil migration into the pulmonary system, besides newly formed pavms, in the differential diagnosis and initiate contrast-CT of the thorax and bronchoscopy.
