Type 2 tracheal agenesis without tracheoesophageal fistula.

Tracheal agenesis is a potentially lethal congenital anomaly first described by Payne in 1900. It can occur in isolation or in association with tracheoesophageal (TO) or bronchoesophageal (BO) fistula, cardiovascular anomalies, limb deformities, vertebral anomalies and gastrointestinal tract abnormalities. There are 47 reported cases of tracheal agenesis up to 1989; 45 of these were associated with TO fistula. Another 15 cases of tracheal agenesis have been reported since then, and all have been associated with TO fistula. We report only the third case of type 2 tracheal agenesis without TO fistula.
