We present two cases of thoracic aortic aneurysm combined with aberrant right subclavian artery. Case 1 was a 71-year-old man, and case 2 was a 74-year-old man with an aortic arch aneurysm associated with a diverticulum of Kommerell. In both cases, we performed total aortic arch replacement through median sternotomy using cardiopulmonary bypass, systemic hypothermia and selective cerebral perfusion. We reconstructed all 4 arch branches. The aberrant right subclavian artery arose from the distal portion of the aortic arch, distal to the origin of the left subclavian artery. It crossed the midline between the esophagus and spine. To prevent compression of the trachea and esophagus by the right subclavian artery, we reconstructed it by the anterior side of the trachea. The postoperative course was uneventful.
