Rationale: Bronchial stenosis after lung transplantation results in obstructive airways disease and increased risk of pulmonary infection. Stenting of bronchial stenosis results in improved airway patency and a reduced infection rate in the year following stent placement. Recurrence of bronchial stenosis after stent placement that fails attempts at debridement and dilatation is a particularly challenging complication. We report our experience with brachytherapy for treatment of 5 cases of recurrent bronchial stenosis after stent placement in lung transplant recipients (LTRs).
