Prenatal ultrasonic diagnosis of esophageal atresia and tracheoesophageal fistula combined with interrupted inferior vena cava: a rare case report.

Purpose: This is an extremely rare case of complicated fetal esophageal atresia (EA) with tracheoesophageal fistula (TEF) and interrupted inferior vena cava (IVC) diagnosed by prenatal ultrsonography and successfully treated with surgical repair.

Methods: A 35-year-old pregnant woman was referred to our center for prenatal ultrasound, and the fetus was found to have a series of abnormalities, such as an interrupted IVC associated with a dilated azygos vein, an upper neck pouch sign of the thorax, and polyhydramnios. With suspicion of EA with TEF and interrupted IVC, the infant was born at 39 weeks of gestation, and successfully underwent the surgical operation.

Results: The baby was doing well after 21 months of follow-up.

Conclusion: It is beneficial for the prenatal ultrasonic diagnosis of EA with TEF in optimizing labor care, postpartum treatment, and prompting neonatal management.
