However, hemolysis related to kinked grafts very rare after central repair for acute aortic dissection. Case presentation A 42-year-old man had undergone replacement the ascending aorta and root type dissection 6 months previously. Laboratory data showed mild 5 later, he began complain fatigue on exertion. The serum hemoglobin level reduced 8.6 g/dL, lactate dehydrogenase levels increased 3071 IU/L with gross change in urine color, indicating hemoglobinuria. We diagnosed mechanical caused by graft planned repeat operation. was resected graft-graft anastomosis performed. Postoperatively, clinical course uneventful, completely resolved. Conclusion herein report case kinking repair. diagnosis swiftly made, patient successfully managed redo surgery.
