目的:探讨超声心动图与双源CT在诊断川崎病冠状动脉瘤(CAA)中的应用价值。方法:对采用超声心动图(2-DE)诊断的川崎病CAA患儿的临床资料进行回顾性分析,并与同时采用双源CT(Dual source computed tomography,DSCT)的诊断进行临床对比研究,比较两者诊断方法在川崎病CAA诊断中的应用价值。结果:超声心动图共检测到84个CAA,52个呈现球状,24个呈现梭状,8个呈现串珠状;DSCT共检测到116个CAA,56个呈现球状,27个呈现梭状,24个呈现串珠状;两种方法的诊断结果无明显差异(P>0.05)。CAA的好发部位主要集中在左冠状动脉主干、前降之和右冠状动脉近段。超声心动图与DSCT在冠状动脉主干扩张及近段动脉瘤的形成上显示一致,但是其中8例合并RCA中段CAA在DSCT中有显示,但是超声心动图未能显示。超声心动图与DSCT冠状动脉主干直径测量上无明显差异,且呈现高度正相关。结论:超声心动图与DSCT在川崎病CAA显示上各具优势,其中超声心动图可对川崎病的冠状动脉病变做出快速而准确的诊断,但是对中、远段病变的显示效果不如DSCT,二者应相互结合以提高川崎病CAA诊断效果。 Objective: To investigate the value of echocardiography and dual-source CT in the diagnosis of Kawasaki’s coronary aneurysm (CAA). Methods: The clinical data of children with Kawasaki disease diagnosed by echocardiography (2-DE) were retrospectively analyzed and compared with those diagnosed by simultaneous dual source computed tomography (DSCT) The diagnostic value of the two methods in the diagnosis of Kawasaki disease CAA. RESULTS: Totally 84 CAAs were detected by echocardiography, 52 were spherical, 24 were fusiform and 8 were beaded. There were 116 CAAs detected by DSCT, 56 were spherical, 27 were fusiform, 24 Beaded; no significant difference between the two methods of diagnosis (P> 0.05). The main site of CAA is mainly concentrated in the left main coronary artery, before the descending and right coronary artery proximal segment. Echocardiography was consistent with DSCT in the dilatation of coronary arteries and the formation of proximal aneurysms. However, 8 of the RCA cases with RCA in the middle of the RCA were shown in DSCT, but echocardiography was not demonstrated. Echocardiography and DSCT coronary artery diameter measurements were no significant difference, and showed a highly positive correlation. Conclusions: Echocardiography and DSCT show advantages in Kawasaki disease CAA. Echocardiography can make rapid and accurate diagnosis of coronary artery lesions in Kawasaki disease. However, The two should be combined with each other to improve the diagnostic efficacy of Kawasaki disease CAA.
