Aortic morphology is associated with age, with the diameter being larger in older people. Thoracic endovascular aortic repair (TEVAR) is a treatment for aortic diseases, such as aortic dissection. When evaluating patients, aortic elongation could interfere with the classification of TEVAR complications. The longitudinal change in aortic length has not been studied in detail. In patients receiving thoracic endovascular aortic repair between 2007 and 2013, we determined the aortic length between the sinotubular junction, left common carotid artery, subclavian artery, and celiac artery on their first five annual follow-up computed tomography (CT) exams. Using the immediate post-TEVAR follow-up CT as the comparison reference and a lengthening of the aortic segment by 10 mm or more as the definition of elongation, 16 of 41 (39%) showed elongation between the innominate artery and celiac artery. When compared with the immediate follow-up CT, a higher proportion of patients showed elongation at the fifth year's follow-up CT than the first year's follow-up CT ( < 0.01), and the average lengthening per year was 1.7 mm. There was progressive lengthening of the aorta after TEVAR.
主动脉形态与年龄有关，老年人的直径较大。胸主动脉腔内修复术（TEVAR）是一种治疗主动脉疾病的方法，如主动脉夹层。在评估患者时，主动脉延长可能会干扰 TEVAR 并发症的分类。主动脉长度的纵向变化尚未详细研究。在 2007 年至 2013 年期间接受胸主动脉腔内修复术的患者中，我们在他们前五年的年度计算机断层扫描（CT）检查中确定了窦管交界处、左颈总动脉、锁骨下动脉和腹腔动脉之间的主动脉长度。使用即刻 TEVAR 后随访 CT 作为比较参考，如果主动脉节段延长 10 毫米或更长，则定义为延长，41 例中有 16 例（39%）无名动脉和腹腔动脉之间出现延长。与即刻随访 CT 相比，第五年随访 CT 比第一年随访 CT 显示出更多的患者出现延长（<0.01），平均每年延长 1.7 毫米。TEVAR 后主动脉逐渐延长。
