Here, we report a fetus with a rare aortic arch anomaly with left aortic arch and
right ductus arteriosus, which has not been reported so far. In this condition, the
aorta extends to the left of the trachea as in normal, while the ductus arteriosus
extends to the right of the trachea and joins the descending aorta posterior to the
trachea, with a cross-ribbon sign.
