Fig. 6From: Fetal double aortic arch: prenatal sonographic and postnatal computed tomography angiography features, associated abnormalities and clinical outcomesThree-dimensional color-rendered image with spatiotemporal image correlation of DAA: The left aortic arch and the dominant right aortic arch develop a complete vascular loop, join the left ductus arteriosus, and converge into the descending aorta together. Symmetrical initial parts of the two branches can probably be observed on each arch. (R-ARCH: right aortic arch; L-ARCH: left aortic arch; RCCA: right common carotid artery; RSA: right subclavian artery; LCCA: left common carotid artery; LSA: left subclavian artery; DA: ductus arteriosus; DAO: descending aorta)Back to article page
