Persistent Expectoration of Pulmonary Artery Embolization Coils Requiring Lobectomy.

Transcatheter embolization is an important tool in the treatment of pulmonary artery and bronchial artery pseudoaneurysms, malformations, and hemorrhage. Migration of coils, particularly through erosion into the associated bronchus, is a rare but known potential complication after the use of intravascular embolization coils in the pulmonary vasculature. Here we present a case of migration of segmental pulmonary artery coils through the right lower lobe bronchus and proximally through the vocal cords, causing significant symptoms of discomfort, hemoptysis, and ongoing expectoration of coils necessitating thoracoscopic right lower lobectomy.
