Acquired tracheoesophageal fistula in a premature infant.

A fatality from an acquired tracheoesophageal fistula (TEF) in a very low birthweight premature infant is presented. Neonatal tracheal and esophageal injuries related to endotracheal (ET) intubation are discussed. The infant had important risk factors for the development of subglottic stenosis: birthweight less than 1000 gm, prolonged positive pressure ventilation, and repeated ET intubation. The pathologic examination was consistent with acquired fistula formation resulting from a combination of preexisting subglottic stenosis and prolonged and repeated ET intubation. The recognition of clinical signs of an acquired TEF, as observed in our patient, followed by expeditious diagnostic testing may be lifesaving.
