The Frozen Elephant Trunk (FET) technique is indicated in acute aortic syndromes with arch involvement and malperfusion of tissues. We sought to report on long-term outcomes of FET in emergent cases of acute aortic syndromes. Twenty-three adult patients were referred to our department for surgical management of acute aortic syndromes and underwent aortic arch replacement using the FET technique between November 2010 and January 2022. The primary outcome was long-term survival. Secondary outcomes were the 30-day mortality rate and the incidence of neurologic complications, i.e., stroke and spinal cord ischemia. The mean patient age was 57.1 (±12.5) years, and the majority (20 patients, 87%) were male. The most common indication was Stanford type A acute aortic dissection (aTAAD) in 17 (74%) patients, followed by non-A non-B dissection in 2 (8.7%) patients, penetrating aortic ulcer (PAU) of the aortic arch in 2 (8.7%) patients, type A intramural hematoma (IMH) in 1 (4.3%) patient and blunt thoracic aortic injury of the aortic arch in 1 (4.3%) patient. Kaplan-Meier survival analysis revealed a 73% survival at 12 months, which persisted up to 11 years of follow-up. The FET technique provides a reliable solution for surgical management of patients with acute aortic syndromes. Excellent, sustained long-term results can be achieved.
“冰冻象鼻”（FET）技术适用于累及主动脉弓且存在组织灌注不良的急性主动脉综合征。我们试图报告FET技术在急性主动脉综合征急诊病例中的长期疗效。2010年11月至2022年1月期间，23例成年患者因急性主动脉综合征被转诊至我科接受手术治疗，并采用FET技术进行了主动脉弓置换。主要结局是长期生存。次要结局是30天死亡率和神经并发症的发生率，即中风和脊髓缺血。患者平均年龄为57.1（±12.5）岁，大多数（20例，87%）为男性。最常见的适应证是17例（74%）患者的斯坦福A型急性主动脉夹层（aTAAD），其次是2例（8.7%）患者的非A非B型夹层、2例（8.7%）患者的主动脉弓穿透性溃疡（PAU）、1例（4.3%）患者的A型壁内血肿（IMH）和1例（4.3%）患者的主动脉弓钝性胸主动脉损伤。Kaplan-Meier生存分析显示，12个月时生存率为73%，该生存率在长达11年的随访中持续存在。FET技术为急性主动脉综合征患者的手术治疗提供了可靠的解决方案。可以取得优异、持续的长期效果。
