Floating aortic arch thrombiblood clots forming in an aorta without aneurysms or atherosclerosisin a normal aorta are exceedingly rare. The etiology is unknown, and there are no guidelines for appropriate treatment strategies. We report a case of floating aortic arch thrombosis in a patient without coagulopathy that was treated surgically. As the mass could not be identified preoperatively as a tumor or thrombus, synthetic graft replacement was performed, allowing resection of the lesion site. Histopathological examination revealed erosion and fissures in the tunica intima of the aorta, which suggested vessel damage to the tunica intima as the cause.
漂浮性主动脉弓血栓形成于无动脉瘤或动脉粥样硬化的正常主动脉中极为罕见。其病因不明，且尚无关于适当治疗策略的指南。我们报告一例无凝血病患者的漂浮性主动脉弓血栓形成病例，该患者接受了手术治疗。由于术前无法将肿块确定为肿瘤或血栓，因此进行了人工血管置换，以便切除病变部位。组织病理学检查显示主动脉内膜有糜烂和裂隙，提示血管内膜损伤是病因。
