Abstract

Over the past decade, the self-expanding metallic stent (SEMS) has been considered a safe and effective modality for treatment of inoperable malignant and selected benign airway diseases. Cases of life-threatening or massive hemoptysis have, however, occurred after placement of firstgeneration tracheal SEMSs. We report a case in which a secondgeneration tracheal SEMS caused ulcer formation and a fistula between the trachea and the brachiocephalic artery 40 months after insertion and discuss the cause, pathogenesis, and clinical features of the massive airway bleeding.
