Technical Success of Stent Placement via Transradial Approach for Aberrant Right Subclavian Artery Stenosis

Purpose To describe a case of recurrent cerebral infarction caused by stenosis at the origin of the aberrant right subclavian artery and to discuss the technical advantages of a radial artery approach for stenting. Methods A right radial artery approach with a balloon guiding catheter was used to perform stenting, under dual antiplatelet therapy. Distal protection was achieved through proximal balloon occlusion, enabling retrograde contrast visualization of the aortic arch and stenotic segment. Results Successful stent deployment was achieved with easy access, accurate vessel selection, and full visualization of the landing zone. No perioperative complications occurred, and postoperative CTA follow-up confirmed the absence of in-stent restenosis. The patient was transitioned to single antiplatelet therapy after six months. Conclusion The radial artery approach with balloon-guided protection appears to be a safe and effective option for treating stenosis at the origin of an aberrant right subclavian artery.
