目的 探讨超声心动图在诊断及随访川崎病冠状动脉病变中的作用。方法 利用超声心动图探查小儿川崎病 2 5 9例 ,对其中 97例进行了随访。结果 2 5 9例中发现冠状动脉病变 48例 (18 5 % ) ,男∶女 =2∶1,小于 1岁年龄组占 36 %。 90 %是在病程 3周内出现 ,左冠状动脉比右冠状动脉更易发生扩张性病变。随访结果表明 ,轻度扩张性病变较易恢复正常。 2例冠状动脉瘤持续存在 ,动脉瘤内径大小是影响预后的主要因素。结论 超声心动图是诊断川崎病并发冠状动脉病变最安全和最准确的方法之一 ,但远端病变尚需接受冠状动脉造影进一步检查。
Objective To investigate the role of echocardiography in the diagnosis and follow-up of coronary artery lesions in Kawasaki disease. Methods 259 children with Kawasaki disease were investigated by echocardiography and 97 of them were followed up. Results Among 255 cases, coronary artery lesions were found in 48 cases (18.5%), male: female = 2: 1, and less than 1 year old group accounted for 36%. 90% is within 3 weeks of course of disease, left coronary artery is more prone to dilatation lesion than right coronary artery. Follow-up results show that mild dilatation lesions easier to return to normal. 2 cases of coronary artery aneurysm persisted, aneurysm size is the main factor affecting the prognosis. Conclusions Echocardiography is one of the safest and most accurate methods for the diagnosis of Kawasaki disease complicated with coronary artery disease. However, further investigation of coronary artery angiography is needed for the diagnosis of distal lesions.
