Use of balloon-expandable metallic stent in a premature infant with congenital tracheobronchial stenosis.

A congenital tracheobronchial stenosis is a rare obstructive lesion of the airway characterized by intrinsic narrowing of a segment of the trachea and bronchi. In this report, we present the smallest premature infant with a congenital tracheobronchial stenosis who has been successfully treated with balloon dilatation and placement of a balloon-expandable metallic stent.
