[Compression of esophagus and trachea by aortic arch anomalies in childhood].

From February 1985 to November 1992, 14 children with aortic arch anomalies and tracheal and/or esophageal compression were treated at the Pediatric Surgery Division of the São Paulo University School of Medicine. There were 3 cases of double aortic arch, 3 of right aortic arch with ligamentum arteriosum and 4 of aberrant right subclavian artery. Accurate diagnosis was based only on barium esophagoradiogram and, eventually, tracheobroncoscopy. The surgical approach was made through a left posterolateral thoracotomy that allowed an adequate exposure of the malformations. There was no operative mortality. There were 3 late post-operative deaths, 2 of them caused by chronic pulmonary lesions owing to delayed diagnosis. The other child died from complications of a severe tracheomalacia which became symptomatic only after the corrective surgery. The diagnosis of the aortic arch anomalies should be early suspected in children with undetermined respiratory symptoms and can be easily made basically by esophagoradiogram and tracheoscopy.
