Using a frozen elephant trunk (FET) in patients with acute aortic dissection is an effective method to induce aortic remodelling after surgery. A 40-year-old man with Stanford type A acute aortic dissection underwent emergency total arch replacement with FET. The FET was inserted into the descending aorta under direct vision. However, transoesophageal echocardiography after the deployment of the FET revealed that it was misdeployed in the false lumen. An additional FET was deployed in the true lumen to redirect the blood flow to the true lumen. The patient was discharged from the hospital without any major complications. Computed tomography 6 months after surgery revealed enhanced aortic remodelling without any signs of stent graft-induced new entry. Additional deployment of a FET into the true lumen could be an option for a misdeployed FET in the false lumen.
在急性主动脉夹层患者中使用冰冻象鼻支架（FET）是术后诱导主动脉重塑的有效方法。一名40岁的斯坦福A型急性主动脉夹层男性患者接受了FET急诊全弓置换术。FET在直视下插入降主动脉。然而，FET展开后经食管超声心动图显示其误置于假腔中。在真腔中额外部署了一个FET，以将血流重新导向真腔。患者出院时无任何重大并发症。术后6个月的计算机断层扫描显示主动脉重塑增强，无任何支架移植物引起的新破口迹象。在真腔中额外部署FET可能是假腔中FET误置的一种选择。
