Tracheal Stenosis Successfully Treated without Surgery in Preterm Infant

Congenital tracheal stenosis is a rare disease that can be life threatening, especially when early identification is missed. A premature twin showed progressive respiratory symptoms at birth and tracheal stenosis, with difficulty intubating. Chest computed tomography scan revealed diffuse tracheal stenosis and left pulmonary artery (LPA) sling. Tracheal ballooning under fluoroscopic guide was successfully performed at 5 days old and maintained with endotracheal intubation until 7 months old. The patient underwent surgery for LPA sling and is doing well without any respiratory symptoms following extubation. Herein, we report the first case of congenital tracheal stenosis in a preterm infant who was successfully treated with tracheal ballooning and conservative management in Korea.
