Coil Intrabronchial Migration in an Arteriovenous Malformation Patient Treated 10 Years Ago

A 56-year-old male who had received transcatheter coil deposition 10 years ago for an arteriovenous malformation (AVM) was admitted to our hospital because of persistent hemosputum. Chest radiograph and bronchoscopy revealed straightened coil bundles in his air way. Recently, less invasive transcatheter intervention has been performed more frequently for treatment of AVM than surgical resection. In our case, however, chest radiography and bronchoscopy showed that the coils might migrate from the deposited site to the airway. Then, right lower lobectomy was undertaken. In AVM patient who received coil deposition, a long-term follow-up is recommended, and surgical resection should be carried out if necessary.
