[Hybrid Repair of Distal Arch Aortic Aneurysm:Total Aortic Arch Repair with the Lupiae Vascular Graft and Thoracic Endovascular Aortic Repair;Report of Two Cases].

Surgical treatment for distal arch aortic aneurysm is generally invasive, and there is no definitive approach for it. We report 2 cases of men who was admitted for the treatment of aortic aneurysm. First case is a 78-year-old man. Two saccular aneurysm were observed on distal aortic arch and descending aorta by contrast-enhanced computed tomography. Two staged-repair was performed with using the Lupiae vascular graft and thoracic endovascular aortic repair(TEVAR). The postoperative course was uneventful, and he was discharged on day 21 after 1st operation. Second case is a 68-yearold man. Dessecting aneurysm was observed on distal aortic arch and descending aorta 3 months after incidence of type B aortic dissection. Two staged-repair was performed with using the Lupiae vascular graft and TEVAR. However, additional TEVAR was performed for enlargement of descending aorta half a year after 1st operation. Two staged-repair using Lupiae vascular graft and TEVAR was useful for alleviating a burden of a patient and avoiding paraplegia.
