目的确定与主动脉瘤腔内修复术（EVAR）后动脉瘤大小变化相关的围手术期因素。方法2008年8月至2014年12月，187例患者在我院接受EVAR治疗。本研究的对象是其中135例无外周动脉病变的患者，并进行了为期3年的CT随访。显著动脉瘤大小变化被定义为囊的大小变化超过5mm从baseline.ResultsSac扩大被确定在25例（18.5%）和囊收缩被确定在59例（43.7%）患者。与囊扩大相关的因素为术后脉搏波速度（OR：比值比3.80，p=0.047）、术后1周2型内漏的患病率（OR 4.26，p=0.022）、内径（OR 1.10，p=0.005）和下肾动脉至终末主动脉的距离（OR 1.05，p=0.017）。与囊收缩相关的因素是2型内漏的发生率（OR 0.09，p
PurposeTo identify the perioperative factors associated with aneurysm size changes after endovascular aortic aneurysm repair (EVAR).MethodsBetween August, 2008 and December, 2014, 187 patients underwent EVAR treatment in our institution. The subjects of this study were 135 of these patients without peripheral artery disease, who were followed up with computed tomography (CT) for 3years. Significant aneurysm size change was defined as sac size change of more than 5mm from the baseline.ResultsSac enlargement was identified in 25 patients (18.5%) and sac shrinkage was identified in 59 (43.7%) patients. The factors associated with sac enlargement were postoperative pulse wave velocity (OR: odds ratio 3.80, p=0.047), prevalence of a type 2 endoleak 1week after surgery (OR 4.26, p=0.022), inner diameter (OR 1.10, p=0.005), and distance from the lower renal artery to the terminal aorta (OR 1.05, p=0.017). The factors associated with sac shrinkage were prevalence of a type 2 endoleak (OR 0.09, p
