We encountered a 75-year-old man who underwent total arch replacement for a thoracic aortic aneurysm, then ascending aortoplasty for hemolysis due to a kinked ascending aortic graft. He presented with exhaustion and anemia 3 years later. Computed tomography revealed a large floating thrombus in the ascending aortic graft attached to the dorsal suture line. The thrombus developed after the graft kink was released, and although the dorsal mural thrombus disappeared, a floating white thrombus remained. Clinicians should ensure that the ascending graft is in a natural position without bending or kinking to reduce the risk of postoperative thrombus formation.
我们遇到一名75岁男性，他因胸主动脉瘤接受了全弓置换术，随后因升主动脉移植物扭结导致溶血而进行了升主动脉成形术。3年后，他出现了疲惫和贫血症状。计算机断层扫描显示，升主动脉移植物内有一个大的漂浮血栓附着于背侧缝线处。血栓在移植物扭结解除后形成，尽管背侧壁血栓消失了，但仍有一个漂浮的白色血栓。临床医生应确保升主动脉移植物处于自然位置，无弯曲或扭结，以降低术后血栓形成的风险。
