目的：探讨超声心动图对小儿川崎病冠状动脉病变的诊断价值。方法：以50例健康儿童的超声监测值为参照,应用多普勒超声技术对2006年10月至2014年3月进行治疗的26例川崎病冠状动脉病变的患儿进行检测,观察冠状动脉内径、冠状动脉壁厚度、回声的强度及有无动脉瘤形成。结果：健康组左冠状动脉主干及右冠脉显示率为100%,病变组检出冠状动脉病变15例(57.7%),其中冠状动脉内径扩张为14例,冠状动脉内径扩张合并内膜增厚为2例,合并心包积液2例,1例为右冠状动脉瘤。冠脉病变最早发生在起病5~7d。结论：超声心动图用于诊断和随访小儿川崎病冠状动脉病变具有安全、方便、迅速、直观的优点,对川崎病冠脉病变具有较高的诊断价值,可作为影像学检查中的首选方法,但对远端冠状动脉损害的检出有一定的困难。%Objectives:To explore the diagnostic value of ultrasound cardiogram in coronary artery lesions resulting from Kawasaki disease. Methods:Doppler ultrasound technique was used to detect 26 cases of coronary artery lesions resulting from Kawasaki disease treated from October 2006 to March 2014 and to observe the inner diameter and wall thickness of the coronary artery, echo intensity and whether there was an aneurysm formed. Results:The display rate was 100 % for the left main coronary artery and right coronary artery in the healthy group;15 cases (57. 7 %) of coronary artery lesions were detected in the group with coronary artery disease , including 14 cases of coronary artery diameter expansion, 2 cases of coronary artery inner diameter expansion with intimal thickening and pericardial effusion respectively, 1 case of right coronary artery aneurysm;the earliest onset of coronary artery lesions occurred in the first 5-7 days. Conclusion:It is safe, convenient, fast and visual to use ultrasound car-diogram for diagnosing coronary artery lesions resulting from Kawasaki disease, which is of diagnostic value. It can be considered to have the priority in the imaging test , but it's a bit difficult to check the damage to the distal coronary artery.
