A 68-year-old man presenting with abdominal distention was found on enhanced computed tomography to have a dilated ascending aorta and aortic dissection (DeBakey IIIb). Through a median sternotomy, we performed a total arch replacement using a four-branched Hemashield graft (Meadox Medical, Oakland, NJ) and a long elephant trunk anastomosis at the base of the innominate artery. Postoperatively, a pseudolumen of the descending aorta was effectively thrombo-excluded to the T12 level. Visceral blood flow was preserved, and the patient's postoperative course was uneventful.
