Double Carotid–Subclavian Bypass Followed by Endovascular Exclusion of a Kommerell Diverticulum and Bilateral Subclavian Artery Occlusion in a Right-Sided Aortic Arch

Aneurysmatic dilatation of the vascular origin of an aberrant subclavian artery, named a Kommerell diverticulum, is associated with a right-sided aortic arch in up to 50% of cases [(1-3)][1]. Specifically, in this specific anatomy, the branches originate from the aortic arch in the following order:
