Endovascular Treatment of an Aberrant Right Subclavian Artery Aneurysm with Use of the Zenith Iliac Plug

Aberrant right subclavian artery aneurysms are rare but demonstrate a propensity toward rupture; thus, early elective repair is mandated. Novel endovascular modalities are available to offer less-invasive treatment for a patient population with increasing comorbidities. We report a case of a 65-year-old woman with an aberrant right subclavian artery aneurysm causing dysphagia lusoria. The aneurysm was excluded proximally at Kommerell's diverticulum with a Zenith iliac plug and excluded distally by surgical ligation combined with a right carotid-subclavian artery bypass to preserve extremity perfusion.
