Tracheal agenesis in newborns.
OBJECTIVE
A series of three newborns with tracheal agenesis is described. The preferred methods of diagnosis, description of the clinical course, and a review of the pertinent embryology, associated anomalies, and clinical management are presented.


METHODS
A retrospective study of a clinical series of referred patients from 2002 to 2003 who were seen at a single institution.


METHODS
Chart review for clinical course and pathological specimens was performed in all cases. Three patients were identified with tracheal agenesis.


RESULTS
All three newborns died within 48 hours of birth. All of the children underwent emergency laryngoscopy and neck exploration. Gross and microscopic pathological examination was accomplished on all patients.


CONCLUSIONS
Although tracheal agenesis is rare, it may be more common than previously thought. The diagnosis is not straightforward, and the prognosis is grim. The embryology of the trachea and other foregut derivatives is closely related, and associated birth defects are common.
