摘　　要：目的 探讨彩色多普勒超声(CDUS)与电子计算机断层扫描血管造影(CTA)在评估颈动脉斑块狭窄程度及斑块形态与数字减影血管造影(DSA)的一致性。方法 选取2020年1月至2022年1月于我院就诊的疑似颈动脉狭窄病变患者140例为研究对象,所有患者均行CDUS、 CTA、DSA检查。查看并对比患者颈动脉狭窄程度及其斑块形态,以DSA检查结果作为金标准,以Kappa分析CDUS、 CTA单独及联合诊断颈动脉狭窄程度及其斑块形态的效能。结果 在140例疑似颈动脉狭窄的对象中,经CDUS检查证实有117例存在颈动脉不同程度狭窄,CTA检测出94例,DSA检测出40例,CDUS、CTA及DSA之间比较差异具有统计学意义(P<0.05),经一致性分析,CTA用于诊断颈动脉狭窄程度的灵敏度及特异性均高于CDUS,联合诊断特异性及灵敏度均高于CTA、CDUS单独诊断;在40例颈动脉狭窄患者中,共检测出80块斑块,CDUS、 CTA及DSA之间不规则斑块检出率比较差异无统计学意义(P>0.05);经一致性分析,CTA用于诊断颈动脉斑块不规则的灵敏度及特异性均高于CDUS,联合诊断特异性及灵敏度均高于CTA、CDUS单独诊断。结论 通过与DSA检查结果对比,CDUS、CTA检查颈动脉狭窄程度及其斑块形态具有一定一致性,联合检测诊断价值更高。Objective To explore the consistency of color Doppler ultrasound(CDUS),digital computed tomography angiogra phy(CTA) to evaluate the degree of carotid plaque stenosis and plaque morphology and digital subtraction angiography(DSA).Methods 140 patients with suspected carotid artery stenosis admitted to our hospital from January 2020 to January 2022 were selected as the study subjects.All patients were examined by CDUS,CTA and DSA.Check and compare the degree of carotid artery stenosis and plaque morphology of patients,take DSA examination results as the gold standard,and use Kappa to analyze the efficacy of CDUS and CTA alone and jointly to evaluate the degree of carotid artery stenosis and plaque.Results Among 140 patients suspected of carotid artery stenosis,117 patients were confirmed to have carotid a rtery stenosis of different degrees by CDUS examination,94 patients were detected by CTA,40 patients were detected by DSA,and the difference between CDUS,CTA and DSA was statistically significa nt(P<0.05).Through consistency analysis,the sensitivity and specificity of CTA in diagnosing carotid stenosis were higher than those of CDUS,and the specificity and sensitivity of combined diagnosis were higher than those of CTA and CDUS alone.80 plaques were detected in 40 patients with carotid stenosis,and there was no significant difference in the detection rate of irregular plaques among CDUS,CTA and DSA(P>0.05).Through consistency analysis,the sensitivity and specificity of CTA in diagnosing carotid plaque irregularity were higher than those of CDUS,and the specificity and sensitivity of combined diagnosis were higher than those of CTA and CDUS alone.Conclusion Compared with DSA results,CDUS and CTA have certain consistency in detecting the degree of carotid stenosis and plaque morphology,and the combined detection has higher diagnostic value.
