Carotid artery stenting in a patient with an incidentally found double aortic arch: A case report

Abstract

Double aortic arch is a type of congenital vascular ring, which rarely presents in adults. Herein, we report a case of carotid artery stenting (CAS) accompanied by an incidentally found double aortic arch. A 77-year-old man presented with bilateral severe carotid artery stenosis. The patient underwent truncal 3D-computed tomography angiography (CTA) to evaluate the access route before CAS, which lead to the diagnosis of an asymptomatic double aortic arch. Referring to the 3D-CTA images, a guiding catheter was successfully navigated to the targeted common carotid artery via the transfemoral approach despite the challenging, complex anatomy of the aortic arch. CAS was performed in both carotid arteries under distal balloon protection, without any neurological deficits. Considering the possible presence of anatomical variants such as double aortic arch, preoperative evaluation of the access route would be efficient for prospective CAS patients.
