Of 136 infants with repaired esophageal atresia, one presented an unilateral facial flushing and 2 presented a flushing and sweating of one half of the body. The topography of these disorders and/or the associated clinical manifestations suggest that the asymmetry may be related to an instability of unilateral autonomic centers more than to a surgical injury of upper thoracic sympathetic chain during esophageal repair.
