"From hero to villain" tracheovascular fistula as an unusual complication of a silicone stent in tracheal stenosis due to brachiocephalic trunk aneurysm

Aortic and great vessel aneurysms may cause stenosis of adjacent structures, including the airway, which can be fatal if severe and may require advanced airway management. We report a case of tracheal stenosis secondary to a brachiocephalic aneurysm that initially responded to silicone stent placement but later developed a tracheal fistula into the aneurysm. Definitive surgical repair was achieved after stent removal. This potential complication should be considered in the management of such cases.
