| 目的 比较超声造影(CEUS)与CT血管成像(CTA)对老年腹主动脉瘤内修复术(EVAR)患者术前病理特征及术后内漏的诊断价值。 方法 回顾性分析广西壮族自治区民族医院2021年6月至2023年6月收治的83例EVAR患者。术前1d和术后1个月,患者均接受CTA和CEUS检查,间隔时间<1周。比较两种方式对患者术前动脉瘤分型、形态、病变部位、相关参数及术后内漏的诊断价值。以CTA为金标准,Kappa分析比较CEUS诊断术前病理类型和术后内漏分型的一致性。结果 CTA和CEUS在瘤体直径、瘤体长度和肾下腹主动脉直径等参数比较,差异无统计学意义(P>0.05)。CTA和CEUS术前评估病理分型、形态、病变部位及其他特征比较,差异无统计学意义(P>0.05)。以CTA检查结果作为金标准,术前CEUS诊断EAVR术前病理类型具有较高的一致性(Kappa=0.978)。以CTA检查结果作为金标准,术后CEUS诊断EAVR术后内漏类型具有较高的一致性(Kappa=0.855)。结论 术前CEUS诊断AAA病理类型及术后内漏分型的效能与CTA相当,可根据患者适应症选择作为CTA检查的补充手段,值得临床推广应用。 |

| Abstract: |
| Objective To compare the pathological characteristics of contrast-enhanced ultrasound (CEUS) and CT angiography (CTA) in elderly patients before endovascular aortic repair (EVAR) and their application value in the diagnosis of postoperative internal leakage. Methods A total of 83 patients undergoing EVAR in Ethnic Hospital of Guangxi Zhuang Autonomous Region were retrospectively enrolled between June 2021 and June 2023. Before and at 1 month after surgery, all underwent CTA and CEUS (interval <1 week). The diagnostic value of the two methods for preoperative aneurysm classifications, morphology, lesion sites, related parameters and postoperative internal leakage was compared. Taking CTA as the golden standard, the consistency of CEUS in the diagnosis of preoperative pathological types and postoperative internal leakage classifications was compared by Kappa analysis. Results There was no significant difference in tumor diameter, tumor length or diameter of abdominal aorta below kidney between CTA and CEUS (P>0.05). There was no significant difference in pathological classifications, morphology, lesions sites and other characteristics between CTA and CEUS (P>0.05). Compared with CTA, preoperative CEUS was of high consistency in the diagnosis of pathological types (Kappa=0.978). Taking CTA results as the golden standard, CEUS was of high consistency in the diagnosis of internal leakage types after EAVR (Kappa=0.855). There was no type VI or type V internal leakage detected by the two methods. Conclusion CEUS has comparable efficiency to CTA in preoperative evaluation of AAA’s pathological types and postoperative diagnosis of internal leakage classifications. CTA can be selected as a supplementary means for CTA according to patient"s indications, which is worthy of clinical promotion and application. |
