多层螺旋CTA联合超声造影对肥胖女性患者颈动脉斑块的评估价值

Evaluated Value of Multi-slice Spiral CTA Combined with Contrast-enhanced Ultrasonography on Carotid Plaques in Obese Female Patients

目的分析多层螺旋CT血管造影(CTA)联合超声造影对肥胖女性患者颈动脉斑块的评估价值。方法选取我院106例肥胖女性颈动脉狭窄患者为受试对象,所有患者均行多层螺旋CTA与超声造影检查,观察颈动脉斑块情况,并与病理结果进行对照分析,评估多层螺旋CTA与超声造影单独与联合评估颈动脉斑块灵敏度、特异度、准确度、阳性预测值、阴性预测值、Kappa值。结果多层螺旋CTA评估颈动脉斑块稳定性,其敏感度、特异度、准确度分别为70.83%、89.02%、84.91%;超声造影评估颈动脉斑块稳定性的敏感度、特异度、准确度分别为75.00%、93.90%、89.62%;多层螺旋CTA联合超声造影评估颈动脉斑块稳定性的敏感度、特异度、准确度分别为79.17%、96.34%、92.45%,其准确度、灵敏度均高于多层螺旋CTA与超声造影单独检测。结论多层螺旋CTA联合超声造影诊断肥胖女性患者颈动脉斑块具有积极意义,有助于提高诊断准确率。

Objective To analyze the evaluated value of multi-slice spiral CT angiography(CTA)combined with contrast-enhanced ultrasonography on carotid plaque in obese female patients.Methods A total of 106 obese women with carotid stenosis in our hospital were selected as subjects.All patients underwent multi-slice spiral CTA and contrastenhanced ultrasonography,and the carotid plaque was observed,and was compared with pathological results,and the sensitivity,specificity,accuracy,positive predictive value,negative predictive value and Kappa value of separate and combined detection of multislice spiral CTA and contrast-enhanced ultrasonography on carotid plaque were evaluated.Results The sensitivity,specificity and accuracy of multi-slice spiral CTA in evaluating the stability of carotid plaque were 70.83%,89.02%and 84.91%respectively.The sensitivity,specificity and accuracy of contrast-enhanced ultrasonography in evaluating carotid plaque stability were 75.00%,93.90%and 89.62%respectively.The sensitivity,specificity and accuracy of multi-slice spiral CTA combined with contrast-enhanced ultrasonography in evaluating carotid plaque stability were 79.17%,96.34%and 92.45%respectively,and the accuracy and sensitivity were higher than those of separate detection of multi-slice spiral CTA and contrast-enhanced ultrasonography.Conclusion Multi-slice spiral CTA combined with contrast-enhanced ultrasonography is useful for the diagnosis of carotid plaque in obese female patients,and it may help to improve the diagnostic accuracy rate.
