Tracheoesophageal fistula: diagnosis with CT
Pediatric Radiology
|January 1, 1985
Insights
This study shows barium esophagram and computerized tomography (CT) effectively identify lower cervical tracheoesophageal fistulas in infants. Imaging revealed fistula locations and esophageal caliber changes.
Area of Science:
- Pediatric Surgery
- Diagnostic Imaging
- Radiology
Background:
- Tracheoesophageal fistulas (TEFs) are rare congenital anomalies.
- Lower cervical TEFs present diagnostic challenges.
Observation:
- A neonate with two lower cervical tracheoesophageal fistulas was assessed.
- Barium esophagram and axial computerized tomography (CT) were utilized for evaluation.
Findings:
- The barium esophagram successfully identified both fistulas.
- Axial CT delineated the esophageal attachment of the upper fistula and fully visualized the lower fistula.
- Esophageal caliber changes, from collapsed to distended, indicated fistula sites.
Implications:
- CT and esophagram are valuable tools for diagnosing lower cervical TEFs.
- Accurate fistula identification is crucial for surgical planning and improved patient outcomes.
Abstract:
A baby with two lower cervical tracheoesophageal fistulas was evaluated with a barium esophagram and computerized tomography (CT). The esophagram identified both fistulas. Axial CT demonstrated the esophageal attachment of the upper fistula and completely displayed the lower fistula. A change in caliber of the esophagus from a collapsed to a distended state marked the site of the fistulas.
