PROSTAGLANDIN-INDUCED FOVEOLAR HYPERPLASIA SIMULATING PYLORIC-STENOSIS IN AN INFANT WITH CYANOTIC HEART-DISEASE

Prostaglandin infusion is used to maintain patency of the ductus arter iosus in infants with cyanotic congenital heart disease. Recently, gas tric outlet obstruction as a result of prostaglandin infusion has been described. In our case, an upper gastrointestinal contrast study seem ed to depict the typical appearance of pyloric stenosis in an infant w ho had received an infusion of prostaglandin for a prolonged period. S erial ultrasonograms, however, disclosed progressive elongation of the antropyloric channel without wall thickening. This report is the seco nd to illustrate prostaglandin-induced gastric outlet obstruction in a vomiting infant with a gastrointestinal series diagnosis of pyloric s tenosis.
