title: The balloon posterior tracheal split: a technique for managing tracheal stenosis in the premature infant.
abstract: Congenital tracheal stenosis (CTS) in the premature infant almost invariably leads to death for lack of effective reconstructive techniques. We hypothesized that the complete or near complete cartilaginous rings of CTS have a weak point in the posterior portion. Aggressive balloon dilation would result in a posterior longitudinal disruption of the trachea, and an expanded tracheal wall would be created after an appropriate period of endotracheal stenting. Three premature infants with multiple anomalies and CTS were treated with endoscopic posterior tracheal splitting, dividing the trachea as predicted. Although two died of complications of congenital heart disease 2 weeks after the procedure, the third child is alive and well at 9 months of age without airway symptoms. The posterior tracheal wall also split when we performed the procedure in a fresh cadaveric CTS patient. We believe that balloon dilation may prove to be a valuable technique in the treatment of premature infants with congenital or acquired tracheal stenosis and/or in children with such complex diseases that major surgery is precluded.
