[Debranching and Endovascular Repair for Kommerell's Diverticulum with Right-sided Aortic Arch;Report of a Case].

Right-sided aortic arch (RAA) is a rare congenital disorder. A 87-year-old man with chest pain was diagnosed with a right-sided aortic arch and Kommerell's diverticulum by computed tomography (CT). The diverticulum had a maximum diameter of 57 mm, and surgical intervention was chosen because of the possibility of rupture and dissection. We performed thoracic endovascular aortic repair( TEVAR) with a commercially available device, consisting of bypass grafting of the supra-aortic branches. The postoperative courses were uneventful. The patient was discharged from the hospital in good clinical condition. Postoperative CT showed complete exclusion of the diverticulum without endoleak and device migration. Debranching TEVAR for Kommerell's diverticulum was safe and effective.
