Surgery for acute type A aortic dissection is highly challenging, even in expert hands. The goal in such emergency circumstances is primarily to save the patient's life. To minimize the perioperative risk, surgeons often choose surgery involving only supracoronary ascending aortic and hemiarch replacement. However, to achieve a successful repair, the extremely fragile dissected aortic layers must be reconstructed proximally and distally. Most of the surgical procedures for patients with acute type A aortic dissection are supracoronary ascending aortic replacements. Thereby, the Florida sleeve procedure is an attractive alternative for reimplanting the entire aortic root into a Dacron graft. This approach has overcome most of the technical problems associated with composite valve graft or valve-sparing procedures. The frozen elephant trunk procedure is particularly appealing for treating acute type A aortic dissection because of its ability to treat malperfusion by encouraging true lumen expansion and potentially reducing longer-term adverse remodelling within the descending aorta.
急性 A 型主动脉夹层的手术极具挑战性,即使是在专家手中也是如此。在这种紧急情况下,主要目标是挽救患者的生命。为了最大限度地降低围手术期风险,外科医生通常选择仅进行冠状动脉以上升主动脉和半弓置换的手术。然而,为了实现成功的修复,必须在近端和远端重建极其脆弱的夹层主动脉层。大多数急性 A 型主动脉夹层患者的手术程序都是冠状动脉以上升主动脉置换。因此,佛罗里达袖套手术是将整个主动脉根部重新植入涤纶移植物的一种有吸引力的替代方法。这种方法克服了与复合瓣膜移植物或保留瓣膜手术相关的大多数技术问题。冷冻象鼻手术特别适用于治疗急性 A 型主动脉夹层,因为它能够通过鼓励真腔扩张来治疗灌注不良,并有可能减少降主动脉的长期不良重塑。
