Aortobronchial fistula after expandable metal stent insertion for pediatric bronchomalacia.
Indications for using expandable metal stents (EMS) for airway disease have expanded considerably during the past decade. Complications have been infrequent but can be potentially life threatening. There are four reported instances of vascular bronchial fistula after Gianturco EMS insertion for managing airway disease in adults. The authors report a case of an aortobronchial fistula in a pediatric patient after Palmaz EMS insertion for treatment of bronchomalacia. A 14-year-old boy with severe scoliosis underwent left mainstem bronchus insertion of two Palmaz stents in tandem for correction of complete bronchial obstruction caused by vascular compression. Three weeks later fatal hemoptysis from an aortobronchial fistula developed. Elective EMS insertion for treatment of airway obstruction secondary to compression by vascular structures should be approached with caution. EMS placement should be reserved for situations in which there is no other reasonable surgical alternative.
