Abstract
A technique for the injection of the cadaver to demonstrate blood supply to the esophagus in the newborn is described having circulation gaps that might have some bearing on the pathogenesis of esophageal atresia. The vulnerability of the blood supply to the lower esophagus is demonstrated, and it is suggested that this blood supply should be preserved, even at the expense of a tense anastomosis, when operating on cases of esophageal atresia.
