Azygous flap technique for reinforcement of esophageal closure

A tissue flap of azygous vein was successfully used for reinforcement of the esophageal anastomosis in two infants with wide-gap esophageal atresia and carinal tracheoesophageal fistula. In spite of anastomotic tension, both esophagi healed without leak or stricture. This technique may be of value in the surgical correction of esophageal anomalies.
