A 65-year-old woman suffered from left-side paralysis and dysarthria after sudden chest pain, and we diagnosed cerebral infarction caused by type A acute aortic dissection in the Stanford classification. At that time, the aberrant right subclavian artery with Kommerell’s diverticulum was found on enhanced computed tomography. The acute aortic dissection with closed false lumen was treated conservatively. Because the ulcer-like projection（ULP）expanded during the course, we performed surgery. Ascending aorta and arch replacement, patch closure of Kommerell’s diverticulum and reconstruction of right subclavian artery were performed simultaneously. The postoperative course was good.
