OBJECTIVES The ideal treatment for aneuryms of aberrant left subclavian arteries with Kommerell's diverticulum arising from right aortic arches remains open. METHODS Between January 2015 and December 2020, five patients with aneurysms from a right-sided aortic arch with aberrant left subclavian artery and Kommerell's diverticulum underwent repair by using the frozen elephant trunk (FET) technique in three aortic centers. Patients' characteristics were retrospectively reviewed and the surgical procedure and outcomes are presented. RESULTS The median age of the 2 male and 3 female patients was 59 (range from 49 to 63) years. Median operative times were as follow: surgery 405 min (range from 335 to 534), cardiopulmonary bypass time 244 min (range from 208 to 280), aortic clamp time 120 min (from 71 to 184). The mean core temperature was 25,94 °C (from 24 to 28). The intensive care unit stay was 4 days (range from 1 to 8) and the in-hospital stay 21 days (from 16 to 34). All patients were discharged and we observed no stroke or spinal cord ischaemia postoperatively. During the median follow-up time of 1003 days (range from 450 to 2306), three patients required subsequent thoracic endovascular distal stent graft extension. CONCLUSIONS The FET technique is a good treatment option for patients with aneuryms of an aberrant left subclavian artery with Kommerell's diverticulum arising from right aortic arches. Secondary stent graft extension is a frequently needed component of the treatment concept.

采用冷冻象鼻技术治疗伴有科默雷尔憩室的左锁骨下动脉异常的右侧主动脉弓动脉瘤。

目的 对于异常左锁骨下动脉瘤伴右主动脉弓引起的科默雷尔憩室，理想的治疗方法是保持开放。方法 2015年1月至2020年12月，在三个主动脉中心采用冷冻象鼻（FET）技术对5例右侧主动脉弓动脉瘤伴左锁骨下动脉异常和Kommerell憩室的患者进行了修复术。回顾性地回顾了患者的特征，并介绍了手术过程和结果。结果 2 名男性和 3 名女性患者的中位年龄为 59 岁（范围为 49 至 63 岁）。中位手术时间如下：手术405分钟（范围从335至534），体外循环时间244分钟（范围从208至280），主动脉钳夹时间120分钟（范围从71至184）。平均核心温度为 25.94 °C（从 24 到 28）。重症监护室住院时间为 4 天（1 至 8 天），住院时间为 21 天（16 至 34 天）。所有患者均已出院，术后未观察到中风或脊髓缺血。在中位随访时间 1003 天（范围从 450 天到 2306 天）期间，三名患者需要随后进行胸腔血管内远端覆膜支架延伸术。结论 FET 技术对于患有异常左锁骨下动脉瘤并伴有右主动脉弓科默雷尔憩室的患者来说是一种良好的治疗选择。二次覆膜支架延伸是治疗概念中经常需要的组成部分。
