Abstract
|
|
|
|
A partial pulmonary artery sling in bronchopulmonary situs inversus with association of congenital distal trachea stenosis is an extremely rare vascular developmental anomaly. Understanding of this unusual anomaly requires deep knowledge of pulmonary arterial embryogenesis. We present an asymptomatic pediatric female after a one-stage operation for Taussig-Bing anomaly and coarctation of the aorta. Contrast-enhanced cardiac CT examination clearly demonstrated partial sling of the pulmonary artery from the right hemithorax and running a course behind the carina and in front of the esophagus before heading to the left hemithorax. Congenital distal trachea stenosis should specifically be evaluated due to strong association with complete cartilaginous rings in majority cases.
