Is Ligation of Azygos Vein Necessary in Primary Repair of Tracheoesophageal Fistula with Esophageal Atresia?

Abstract

Preservation of the azygos vein maintains the normal venous drainage of mediastinum and hence decreases the postoperative chest congestion and pneumonitis in the postoperative period in cases of congenital esophageal atresia with tracheoesophageal fistula, so it should be preserved whenever possible.
