P44.12: Prenatal and postnatal imaging findings of Fetal Tuberous Sclerosis

Abstract

Subjectively small or absent stomach bubble on classical ultrasound scan is associated with tracheoesophageal fistula/esophageal atresia and appropriate diagnosis of esophageal atresia (EA) significantly improve outcome. The antenatal diagnosis of esophageal atresia by the presence of polyhydroamniosis and an absent stomach bubble is well documented. A significant number of esophageal atresia are associated with a tracheoesophageal fistula. We present a case of long gap esophageal atresia with a fistula diagnosed prenatally by 3D US at 32 weeks 5days (Accuvix, Medison, korea). The 3D US findings are an absent stomach, polyhydroamnios, pouch sign of the esophageal blind end. After delivery, the baby had twice operations for long gap esophageal atresia with tracheoesophageal fistula (on the 11th day: tracheoesophageal fistula ligation with gastrostomy, on the 2 months later: intrathoracic esophagogastrostomy). Technique of reconstructing 3D volume is fast, accurate and produces high-quality images that are easy to reproduce of tracheal pouch.
