title: The Presence of a Right Aortic Arch Associated with Severe Stenosis of the Right Common Carotid Artery and Steal Phenomenon.
abstract: The aim of this article is to describe the clinical presentation and imaging findings of the right-sided aortic arch, an uncommon anatomical variant. We present a case of associated steal syndrome, to our knowledge the first such case in the literature. Diagnostic imaging of a 49-year-old woman with symptoms of cerebrovascular insufficiency revealed the presence of a right aortic arch, with an aberrant left subclavian artery (lusorian artery). This arrangement placed pressure on the right common carotid artery at the level of its departure with the steal phenomenon dependent on the respiratory phase.
