A 66-year-old man was admitted to our institute for surgical treatment of chronic dissecting aortic arch aneurysm with right-sided aortic arch which occurred 2 months previously. The size of the aortic arch aneurysm was larger than 6 cm. Total arch replacement using open stent grafting was performed through median sternotomy. The postoperative condition was well, and the patient was discharged without any complications.
