Prenatal diagnosis of left-sided aortic arch, right descending aorta and right-sided ductus arteriosus associated with anomalous origin of left pulmonary artery from ascending aorta.
Left-sided aortic arch (LAA), right descending aorta (rDAo), and right-sided ductus arteriosus (RDA) constitute a rare aortic arch anomaly. Moreover, anomalous origin of the pulmonary artery from the ascending aorta, especially that of the left pulmonary artery, is also a rare anomaly of the pulmonary artery branches. Because of the presence of the ductus arteriosus, prenatal ultrasound is an optimal diagnostic tool for the LAA with rDAo. Four-dimensional color Doppler can clearly demonstrate the spatial relationship between the LAA, rDAo, and RDA and the anomalous origin of the left pulmonary artery from the ascending aorta.
