Management of recurrent airway strictures in lung transplant recipients using AERO covered stents.

The potential role of AERO tracheobronchial covered stents in the management of recurrent postinfectious strictures of the bronchus intermedius was studied in three lung transplant recipients. Six devices were inserted. Five of the stents migrated immediately on placement. Buildup of thick mucus was observed in all stents remaining in the airway for longer than 1 week. Strictures recurred in all patients 1, 3, and 5 months after stent deployment. Attempts at stent retrieval were successful for three of five devices. The use of AERO stents may not offer a therapeutic advantage versus balloon dilation of bronchus intermedius strictures in lung transplant recipients.
