Surgical and endovascular treatment of dysphagia lusoria in right-sided aortic arch with aberrant left subclavian artery with Kommerell diverticulum: Literature review and two case reports

Abstract

Aberrant Subclavian Artery (ASA) is a rare anomaly within the aortic arch. In some cases, an aneurysm can also develop in the proximal ostium of the ASA which is called Kommerell diverticulum. In this article we report two symptomatic patients with a rare anatomical anomaly caused by a right sided aortic arch and left aberrant subclavian artery with Kommerell diverticulum causing dysphagia lusoria. In the first patient with hemoptysis we conducted surgical excision of the left subclavian artery origin along with bypass end-to-side bypass grafting. In the second patient we transected and ligated the left subclavian artery and with an end-to-side bypass transposition graft, followed by thoracic endovascular repair with simultaneous coil embolization of the Kommerell diverticulum.
