摘　　要：目的探讨超声造影(CEUS)评估腹主动脉瘤腔内修复(EVAR)术前情况及术后内漏分型的临床应用价值。方法选取在我院行EVAR术的老年腹主动脉瘤患者83例,均于术前1 d应用CEUS和CTA分别测量瘤体直径、瘤体长度和肾下腹主动脉直径,同时获取腹主动脉瘤分型、形态、病变部位、其他图像特征,比较两种方法检查结果的差异。以术后1个月CTA检查结果为金标准,计算CEUS诊断腹主动脉瘤患者EVAR术后内漏分型的准确率,分析CEUS与CTA诊断结果的一致性。结果术前CTA和CEUS测量腹主动脉瘤患者瘤体直径、瘤体长度和肾下腹主动脉直径及评估腹主动脉瘤分型、形态、病变部位、其他图像特征比较,差异均无统计学意义。CEUS诊断腹主动脉瘤患者EAVR术后内漏Ⅰ型、Ⅱ型、Ⅲ型的准确率分别为66.67%(2/3),100%(5/5)和100%(3/3),CEUS与CTA诊断结果的一致性高(Kappa=0.855)。结论CEUS评估腹主动脉瘤患者EVAR术前情况及术后内漏分型的价值与CTA相当,具有较好的临床应用价值。Objective To explore clinical application value of contrast-enhanced ultrasound(CEUS)in the evaluation of preoperative conditions and internal leakage classifications in abdominal aortic aneurysm after endovascular aortic repair(EVAR).Methods A total of 83 elderly patients with abdominal aortic aneurysm who underwent EVAR in our hospital were enrolled.CEUS and CTA were performed to measure the tumor diameter,length,and diameter of subrenal abdominal aorta 1 d before EVAR,and the classifications of abdominal aortic aneurysm,morphology,lesion sites and other manifestations of abdominal aortic aneurysm were obtained at the same time.The differences in the results of the two methods were compared.Taking CTA results as the golden standard,the accuracy of CEUS in the diagnosis of internal leakage classifications was calculated,and the consistency between the results of CEUS and CTA was analyzed.Results There were no significant difference in tumor diameter,length,diameter of subrenal abdominal aorta,classifications,morphology,lesion sites and other manifestations of abdominal aortic aneurysm between CTA and CEUS.Taking CTA results as the golden standard,accuracy of CEUS in the diagnosis of typesⅠ,ⅡandⅢinternal leakage after EAVR were 66.67%(2/3),100%(5/5)and 100%(3/3),respectively,showing high consistency(Kappa=0.855).Conclusion The value of CEUS in evaluating the preoperative conditions and postoperative leakage classifications of EVAR in patients with abdominal aortic aneurysm is comparable to CTA,which has good clinical application value.
