Extended aortic replacement from the aortic arch to the descending thoracic or thoracoabdominal aorta has been performed through a left thoracotomy or a thoracoabdominal incision combined with or without a median sternotomy. However, a left thoracotomy incision may be unfavorable when dense adhesion of the lung is anticipated. We report a redo patient who underwent simultaneous replacements of the aortic arch and the thoracoabdominal aorta through a midline incision without entering the left pleural cavity.
