Acute type A dissection (ATAAD) remains a morbid condition with reported surgical mortality as high as 25%. We describe our surgical approach to ATAAD and discuss the indications for adjunct techniques such as the frozen elephant trunk or complete aortic repair with endovascular methods. Arch replacement using the "branch-first technique" allows for complete root, ascending aorta, and arch replacement. A long landing zone is created for proximal endografting with a covered stent. Balloon-assisted intimal disruption and bare metal stenting of all residual dissected aorta to the level of the aortic bifurcation is then performed to obliterate the false lumen (FL) and achieve single true lumen (TL) flow. Additional branch vessel stenting is performed as required.
急性A型主动脉夹层(ATAAD)仍然是一种严重疾病,报告的手术死亡率高达25%。我们描述了我们对ATAAD的手术方法,并讨论了诸如冷冻象鼻技术或采用血管内方法进行全主动脉修复等辅助技术的适应症。使用“分支优先技术”进行主动脉弓置换可实现主动脉根部、升主动脉和主动脉弓的完全置换。为使用覆膜支架进行近端血管内移植创造一个长的着陆区。然后进行球囊辅助内膜破坏和对所有残余的主动脉夹层直至主动脉分叉水平进行裸金属支架置入,以消除假腔(FL)并实现单一真腔(TL)血流。根据需要进行额外的分支血管支架置入。
