A 62-year-old woman presented with acute chest pain. An enchanced CT scan showed type A closing aortic dissection. An ulcer-like projection (ULP) was observed in the abdominal aorta above the superior mesenteric artery on aortography. At 3 months after onset, recurrent chest pain appeared. An enchanced CT scan showed a false lumen in the ascending aorta and a new ULP and localized false lumen were opacified in the distal ascending aorta on aortography. The graft replacement of the ascending aorta was performed using open distal anastomosis under circulatory arrest and retrograde cerebral perfusion. Two intimal tears were found in the aortic root and distal ascending aorta. The patient recovered without complications. Postoperative CT scan and aortography revealed no residual false lumen.
