Special Considerations on the Arterial Duct and Aortic Arch Views
Visualization of the long-axis views of the aorta and arterial duct is facilitated in the fetus if one refers to a transverse section of the upper mediastinum as the starting point. For instance, the long-axis view of the aortic arch is obtained from the transverse view of the fetal thorax by rotating the scan plane 90° when the ascending and the descending aorta are aligned with the ultrasound-beam axis. In the normal fetus in ventral presentation, this alignment is obtained by placing the transducer on the right parasternal area (Fig.16.1).
