Resection of distal tracheal stenosis in a baby with agenesis of the lung.

A newborn infant with agenesis of the left lung and critical distal tracheal stenosis required tracheal resection and reanastomosis. This case illustrates the combined use of flow-volume curves, radiology and endoscopy in the diagnosis and management of airway obstruction in infants. It also establishes the feasibility of complete tracheal reconstruction in small babies.
