A 74-year-old woman was referred to our unit with a chief complaint of dysphagia. Enhanced CT showed a Kommerell diverticulum with a maximum diameter of 46mm, associated with a right-sided aortic arch and aberrant left subclavian artery. We performed two-staged operations:left subclavian-common carotid artery bypass followed by total arch, and descending aortic replacement by an antero-lateral thoracotomy with partial sternotomy(ALPS). The postoperative course was uneventful. Total arch and descending aortic replacement for a Kommerell diverticulum by an ALPS approach is rare. ALPS approach for Kommerell diverticulum achieves safe surgery with good exposure.
