We report a rare case of a patient with hemolytic anemia who underwent emergency total arch replacement using the elephant trunk technique for type A acute aortic dissection 3 years earlier. The 78-year-old woman was referred to our hospital for diagnosis of the cause of the hemolytic anemia, which required twice weekly blood transfusion. Although contrast-enhanced computed tomography could not provide sufficient information, transesophageal echocardiography (TEE) revealed graft flection with high velocity. After percutaneous balloon dilatation, the hemolytic anemia improved and follow-up TEE showed no re-stenosis of the dilatation site.
