A 74-year-old man was admitted to our hospital to undergo an operation for distal aortic arch aneurysm with chronic aortic dissection. The first operation was attempted through left lateral thoracotomy. Since the aorta had a severely calcified false lumen, conventional aortic replacement was considered to entail greater risk and graft replacement was given up. As an another option, endovascular stent grafting via the aortic arch through median sternotomy was selected as a second operation. Deep hypothermic circulatory arrest with selective cerebral perfusion was used during delivery and deployment of the stented graft through the aortotomy site. The distal stented graft was deployed into the true lumen at the ninth thoracic vertebral level. Neither endoleaks nor complications were observed. Postoperative computed tomography showed complete thrombosis of the distal aortic arch aneurysm and the false lumen. The postoperative course was uneventful. Transaortic endovascular stent grafting is an effective and less invasive treatment for aortic arch aneurysms with severely calcified aorta.
