Abstract

A newborn male was admitted with cyanosis and respiratory distress. Echocardiography showed a right heart isomerism associated with a single right ventricle, a double-outlet right ventricle, and pulmonary atresia. Chest X-ray demonstrated severe left upper lobe emphysema and a shift of the mediastinal structures to the right. Two-dimensional computed tomography (CT) exhibited left upper lobe emphysema and right upper lobe atelectasis. Three-dimensional (3D) spiral CT angiography showed a bilateral tracheal bronchus. The left tracheal bronchus branch was compressed between the descending aorta and the ductus arteriosus. After a right arteriopulmonary shunt operation, the patient's respiratory condition improved dramatically, with spontaneous closure of the ductus arteriosus. Subsequently, 3D-CT clearly exhibited the disappearance of tracheal compression. This combination of bilateral tracheal bronchus and congenital heart anomaly is extremely rare. The 3D-CT is a powerful noninvasive means for dynamically demonstrating the special relationships of arterial and tracheal anomalies.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
