Prenatal diagnosis of double aortic arch with subaortic left brachiocephalic vein and right-side ductus arteriosus using high-definition flow render mode and spatiotemporal image correlation.

Double aortic arch (DAA) with subaortic left brachiocephalic vein (LBCV) and right-side ductus arteriosus (RDA) was not reported before delivery, only in adults with anatomy course findings. We present a case of fetal DAA with subaortic LBCV and RDA using high-definition (HD) flow render mode and spatiotemporal image correlation (STIC).
