Agenesis of Azygos Vein in a Case of Esophageal Atresia and Tracheoesophageal Fistula

A 2-day-old female neonate, weighing 2.7kg, presented with salivation, frothing, and choking at feeding attempts. There was a history of polyhydramnios in mother. The baby was a product of non-consanguineous marriage and delivered at term by normal vaginal delivery in a private hospital. General physical examination was unremarkable. There were no visible associated anomalies in the baby. Chest and upper abdominal radiograph showed feeding tube curled just beyond thoracic inlet and a big gastric shadow. Laboratory investigations were within normal limits. Patient underwent right thoracotomy which revealed agenesis of azygos vein (Fig. 1). Primary esophageal repair was done with mild anastomotic tension. Postoperative recovery was uneventful. Echocardiogram done postoperatively showed structurally and functionally normal heart. Patient was discharged in good general condition.
