MSCT与TTE对川崎病冠状动脉瘤中的诊断价值对比研究

Comparison on Diagnostic Value between MSCT and TTE for Coronary Aneurysms in Kawasaki Disease

目的探讨多层螺旋CT(MSCT)与经胸超声心动图(TTE)对川崎病(KD)冠状动脉瘤的诊断价值。方法选取我院就诊治疗的86例KD冠状动脉瘤患儿作为研究对象,对所有患儿临床资料进行回顾性分析,以病理检查诊断为标准,比较不同检查方法KD冠状动脉瘤的诊断符合率、灵敏度和特异性,并整理分析KD冠状动脉瘤在不同检查方法中的影像学表现。结果86例患儿冠状动脉病灶共检出154个,MSCT病灶检出率为97.40%(150/154),诊断符合率为95.35%(82/86),TTE病灶检出率为92.21%(142/154),诊断符合率为88.37%(76/86),两种方法检查在KD冠状动脉瘤病灶检出及诊断符合率比较上差异无统计学意义(P>0.05)。结论 MSCT和TTE检查对KG冠状动脉瘤检出和诊断率一致,图像表现类似,但MSCT图像显示更为清晰,且所受相关因素影响小,故可结合检查以弥补TTE足,进一步提高KD冠状动脉瘤诊断正确率,为临床治疗进一步提供指导价值。

Objective To investigate the diagnostic value of multi-slice spiral CT(MSCT and transthoracic echocardiography(TTE)for coronary aneurysms in Kawasaki disease(KD).Methods 86 children with KD coronary aneurysms who were treated in our hospital were selected as subjects.The clinical data of all children were retrospectively analyzed.The pathological examination was used as the standard to compare the diagnostic accuracy,sensitivity,and specificity of different examination for KD coronary aneurysms and to analyze the imaging manifestations of KD coronary aneurysms in different examination methods.Results 154 lesions of coronary artery were detected in 86 children.The detection rate of lesions by MSCT was 97.40%(150/154),and the diagnostic coincidence rate was 95.35%(82/86).The detection rate of lesions by TTE was 92.21%(142/154),the diagnostic coincidence rate was 88.37%(76/86).There was no difference in the detection rate and coincidence rate for lesions of KD coronary aneurysm between the two methods(P>0.05).Conclusion The MSCT and TTE examinations have consistent detection rates and diagnosis rate for KG coronary aneurysms,and the image is similar.However,the MSCT image is clearer and it is less affected by relevant factors.Therefore,it can be combined to make up for the deficiency of TTE,further improve the diagnostic accuracy of KD coronary aneurysm,and provide further guidance for clinical treatment.
