Video 44.5 Aortic arch 2D and color
Aortic arch 2D and color. Normal aortic arch in a 19-week fetus. The aortic arch is shown in the sagittal plane in 2D and with color Doppler. The aorta arises from the center of the fetal chest and has a “cane handle” appearance. The right pulmonary artery is seen in cross-section under the aortic arch and the ductus arteriosus is seen joining the aorta at the junction of the distal aortic arch and descending aorta. Also seen in this image is the inferior vena cava entering the right atrium.
