目的：在DeBakey I型急性主动脉夹层中，采用冷冻象鼻技术对近端和远端胸主动脉进行联合治疗。本研究分析了远端主动脉的解剖特征及其对假腔（FL）血栓形成和主动脉重塑的影响。 方法：2005年3月至2015年3月期间，94名接受冷冻象鼻治疗的I型急性主动脉夹层患者中的63人获得了足够的术前、术后和至少1年随访计算机断层扫描数据集。 主动脉重塑和FL血栓形成在覆膜支架水平 (A)、从 A 到腹腔干 (B) 以及从 B 到分叉处 (C) 进行体积计算，并与各节段 FL（出口）产生的入口撕裂和主动脉分支的数量和大小相关。 结果：节段 A (94%)、B (64%) 和 C (54%) 发现阳性或稳定重构，FL 血栓形成商为第一年内，A 为 98%，B 为 68%，C 为 39%。 FL 血栓形成与入口总大小呈负相关 (P
OBJECTIVES: In DeBakey Type I acute aortic dissection, the frozen elephant trunk technique is used for the combined treatment of both the proximal and distal thoracic aorta. Anatomical characteristics of the distal aorta and their impact on false lumen (FL) thrombosis and aortic remodelling were analysed in this study.METHODS: Sufficient pre-, postoperative, and at least one 1-year follow-up computed tomography data sets were available for 63 of 94 patients treated with the frozen elephant trunk for Type I acute aortic dissection between March 2005 and March 2015. Aortic remodelling and FL thrombosis quotients were calculated volumetrically at the stent graft level (A), from A to the coeliac trunk (B) and from B to the bifurcation (C) and were correlated with the number and size of entry tears and aortic branches arising from the FL (exits) in each segment.RESULTS: Positive or stable remodelling was found in Segments A (94%), B (64%) and C (54%), and the FL thrombosis quotient was 98% in A, 68% in B and 39% in C within the first year. FL thrombosis correlated negatively with the total size of the entry (P
