Diaphragm Translocation as Surgical Treatment for Agenesis of the Right Lung and Secondary Tracheal Compression

A 12-month-old boy was diagnosed with agenesis of the right lung. Mediastinal deviation progressed to the diseased side as the patient matured; therefore, tracheal distortion developed. As a result, tracheal compression developed between the vertebral body and aorta. The patient was repeatedly admitted to the hospital because of recurrent pulmonary infection and combined severe respiratory distress. Diaphragm translocation was performed to treat the patient. The postoperative course was favorable, and computed tomography scan findings and symptoms had improved at 1 year after surgery.
