- Abstract: A man in his fifties was diagnosed with retrograde type A acute aortic dissection. He underwent total arch replacement using the Gelweave Lupiae graft and staged thoracic endovascular aortic repair. Five days after discharge from the hospital, he was referred to our institution because of severe hemolytic anemia. Electrocardiography-gated computed tomography angiography demonstrated significant kinking of the graft adjacent to the proximal anastomotic site. Cine cardiac magnetic resonance imaging showed that graft kinking deteriorated during systole. We concluded that his hemolytic anemia was caused by graft kinking and surgical repair was required. The graft was transected at the kinking site and then reconstructed. After surgical repair, the hemolytic anemia improved immediately.
