A 52-year-old woman with Marfan syndrome developed Stanford type B aortic dissection and was treated with thoracic endovascular aortic repair. However, 29 months later, she presented with retrograde Stanford type A aortic dissection. We successfully performed aortic arch replacement with the frozen elephant trunk technique and valve-sparing aortic root replacement. The advantages of the frozen elephant trunk technique are that the distal anastomosis can be created without stent-graft resection and the cardiac arrest time is shortened. Therefore, the frozen elephant trunk technique was considered valuable and safe in this potentially lethal situation.
一名患有马凡综合征的52岁女性发生了B型主动脉夹层，并接受了胸主动脉腔内修复术治疗。然而，29个月后，她出现了逆行性A型主动脉夹层。我们成功地采用了带冰冻象鼻技术进行主动脉弓置换和保留瓣膜的主动脉根部置换。带冰冻象鼻技术的优点是无需切除覆膜支架即可进行远端吻合，且缩短了心脏停搏时间。因此，在这种可能致命的情况下，带冰冻象鼻技术被认为是有价值且安全的。
