Diagnosis of a proximal tracheoesophageal fistula using three-dimensional CT scan: a case report.

Missed proximal tracheoesophageal fistulas (TEF) after repair of an esophageal atresia (EA) with distal TEF are rare. The diagnosis usually is made on the basis of bronchoscopy and esophagoscopy, which can be inaccurate. Recent advances in computerized tomography (CT) have allowed saggital, coronal, and 3-dimensional reconstruction of any structure or organ. The authors report a case in which 3-dimensional CT was used to assist in the diagnosis of a missed proximal TEF in a 16-year-old girl.
