Question

Quizplus · Accepted Answer

Chest and abdominal radiographs are critical to the diagnosis of esophageal atresia and tracheoesophageal fistula.Several important radiographic findings are specific for esophageal atresia.The course and end point of the nasogastric tube confirm obstruction of the proximal esophagus by atresia and determine the relative position of the upper esophageal pouch.The lung fields must be examined to determine the presence of parenchymal changes resulting from aspiration.Changes in mediastinal structures give an early indication of congenital heart disease,and a careful search is made for the aortic arch to determine its left- or right-sided position.
