Hybrid Repair for Mega-Aortic Syndrome due to Giant Cell Aortitis in a Heart Failure Patient

抄録

The present report describes a case of mega-aortic syndrome accompanied with severe aortic regurgitation in a 75-year-old man who underwent a two-stage hybrid repair. Intraoperative pathologic findings at the first repair, consisting of Bentall operation and total arch replacement with a Lupiae graft, aided the identification of the giant cell aortitis. Despite complicating hemorrhagic stroke, steroid therapy was initiated and endovascular repair was subsequently completed. Over more than 2 years of follow-up, the patient continued steroid therapy and is doing well without any reintervention.
