Endovascular Repair of a Kommerell's Diverticulum and Aneurysmal Right-sided Aortic Arch: A Case Report.

Right-sided aortic arch with aberrant left subclavian artery is an uncommon anomaly. We describe a case of Kommerell's diverticulum involving the distal portion of a right-sided aortic arch and the origin of an aberrant left subclavian artery in a 74-year-old man with hoarseness. The patient underwent successful endovascular repair of the aneurysm with use of a Gore TAG thoracic endoprosthesis and coil embolization of the left subclavian artery. Postoperative computed tomography showed complete exclusion of the lesion, without endoleaks. Endovascular repair is feasible and can be effective in such cases.
