Figure 3.

Computed tomograms displaying (A) the right common carotid artery and left common carotid artery, both arising from the aortic arch; (B) the left subclavian artery and right subclavian artery with aberrant origin and diverticulum of Kommerell (the distal remnant of the right aortic arch), and (C) the left-sided aortic arch with an aberrant right subclavian artery arising from the proximal part of the descending aorta, with retrotracheal and retro-oesophageal course, but without obstruction. The arrow indicates the right subclavian artery emerging from proximal descending aorta.
