Fig. 6.32  Suprasternal aortic arch short-axis view

2.28.1\ Scanning Methods

The patient is lying flat (supine) with the neck hyperextended. The probe is placed in the suprasternal notch with a 90° rotation of the probe from the aortic arch long-axis view, directed inferiorly towards the heart.

2.28.2\ Section Structure

Transverse cross section of aortic arch and long axis of right pulmonary artery with its superior and inferior branches should be shown, while the superior vena cava can also be seen in this view sometimes.

2.28.3\ Measuring Method and Normal Value

The normal anterior-to-posterior diameters of aortic arch and right pulmonary artery are 28 ± 3 and 17 ± 3 mm.

2.28.4\ The Clinical Application Value

Being complementary to the aortic arch long-axis view, this view can be used to observe whether the right pulmonary artery, aortic arch, and superior vena cava are normal or not.
