Aortic arch anomalies associated with long gap esophageal atresia and tracheoesophageal fistula.
OBJECTIVE
The purpose of this study was to determine whether aortic arch anomalies are associated with long gap esophageal atresia and tracheoesophageal fistula (EA-TEF).


METHODS
The authors performed a retrospective review of all infants who had EA-TEF from 1980 to 1996 at two pediatric surgery centers. Two hundred three infants who had EA-TEF were identified.


RESULTS
Twelve infants were noted to have both long gap EA-TEF defined as a gap length greater than 3 cm and aortic arch anomalies. Of these 12, 7 had aberrant right subclavian arteries originating from the descending aorta. Four of the seven infants who had aberrant right subclavian artery (SCA) had gap lengths greater than 4 cm. All four had their fistulae divided initially through a right thoracotomy with primary repair performed at a later date. The remaining five infants who had long gap EA-TEF had right-sided aortic arch with aberrant left subclavian arteries. All five initially underwent exploration through the right chest. On discovery of the long gap EA and concurrent vascular anomaly, the thoracotomies were closed, and the infants underwent definitive repair of both their EA-TEF and their vascular anomaly through a left thoracotomy.


CONCLUSIONS
The authors find that aortic arch anomalies are associated with long gap EA-TEF. Patients who have these two anomalies tend to have a long gap. Preoperative diagnosis of these anomalies may alter the timing and technique of surgical intervention. The embryogenesis of these vascular lesions may account for this more severe form of esophageal atresia.
