Curling of the NG tube is seen within the dilated proximal oesophagus.
Contrast (diluted non-iodinated) was introduced through the NG tube slowly. Instillation of contrast via the NG tube fills the proximal esophagus with no distal transit. No communication between the proximal oesophagal pouch and airway is seen.
Gas is demonstrated in the stomach and bowel loops across all the images. Given the proximal atresia, this suggests a fistula between the airways and distal oesophagus.
