The patient was a 73-year-old man who was referred to our hospital due to an abnormal thoracic shadow. CT scans revealed Kommerell’s diverticulum and saccular aortic arch aneurysm accompanied by abnormal origins of the right aortic arch and the left subclavian artery. Although there were no subjective symptoms, a surgical operation was planned considering the risk of a rupture of the saccular aneurysm. For the surgery, a median sternotomy approach was employed. Under cardiopulmonary bypass, the aortic arch was detached using the open distal method. Further, an open stent graft was inserted, and the aortic arch was replaced with a four-branched artificial blood vessel. After weaning off the cardiopulmonary bypass, coil embolization was performed on the left subclavian artery, and the site was checked to ensure that there was no endoleak. Although hoarseness was noted postoperatively due to paralysis of the right vocal cord, the patient progressed without any other major complications and was discharged 30 days after the operation.
