Symptomatic intravascular hemolysis after prosthetic aortic graft replacement is rare. It is primarily attributed to mechanical injury of red blood cells caused by stenosis of the vascular graft. A 50-year-old man presented with hemolytic anemia, 5 years after total arch replacement with an elephant trunk for type A aortic dissection. The hemolysis was caused by graft stenosis of the elephant trunk. Endovascular treatment for the stenotic elephant trunk was successfully performed. The postoperative course was uneventful, and the hemolysis was resolved immediately after operation.
