Recurrent Endobronchial Coil Migration Associated With Needle Biopsy Following Pulmonary Artery Pseudoaneurysm Embolization

Endobronchial coil migration is a rare complication of pulmonary artery embolization, occurring when coils erode through a vessel into an airway. We describe a patient who underwent embolization of pulmonary artery pseudoaneurysms associated with a lung mass. The unique aspect of this case is the development of recurrent endobronchial coil migration following a CT-guided core needle biopsy and a subsequent endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) of the mass. In both circumstances, the portion of the coil that migrated into the large airways was cut with endoscopic scissors and removed with a flexible bronchoscope. This case highlights that while cutting and removing a portion of a migrated coil bronchoscopically is an effective approach, it can be associated with a risk of recurrent coil migration, haemoptysis, and pneumonia.
