A 68-year-old woman, who had been well for two years after ascending aortic graft replacement, experienced sudden chest pain. Computed tomography showed a large false aortic aneurysm around the prosthetic graft. However, the patient was hemodynamically stable and did not have anemia. Urgent surgical procedure under hypothermic circulatory arrest revealed tears at both the proximal and distal anastomotic sites and blood circulating from the proximal (entry) to the distal (re-entry) tears underneath the pericardium. To our knowledge, the present case represents unreported pathology that could be of great interest to cardiologists and cardiac surgeons.
一名68岁女性，在升主动脉移植置换术后两年情况良好，却突然出现胸痛。计算机断层扫描显示人工血管周围有一个巨大的假性主动脉瘤。然而，患者血流动力学稳定且无贫血。在低温循环停止下进行的紧急手术显示，近端和远端吻合部位均有撕裂，血液在心包下方从近端（入口）撕裂处流向远端（再入口）撕裂处。据我们所知，本病例代表了一种未报道过的病理情况，可能会引起心脏病专家和心脏外科医生的极大兴趣。
