- Abstract: A 85-year-old man with an abnormal shadow on X-ray was given a diagnosis of aortic arch aneurysm by CT scan. Preoperative additional careful examinations revealed that his dominant vertebral artery was the left one and he had an allergy to metals such as platinum, tin and zinc. He underwent thoracic endovascular aortic repair (TEVAR) after revascularization of left vertebral artery by bypass grafting between bilateral axillary arteries and the left common carotid artery with a T-shape graft. Because of the position of the origin of the left vertebral artery from the left subclavian artery was comparatively proximal part, we made it transposition more distally to occlude the LSA by ligation. We selected conformable GORE® TAG® for zone-1 TEVAR because the stent graft, which was not composed of allergic metals, contained only less allergic metals than any other devices commercially available. More than two years have passed since his discharge and he was followed as an outpatient without any allergic symptom and other remarkable complications. Here, we report a rare case of 2 debranching TEVAR for aortic arch aneurysm with metal allergy.
