摘　　要：目的 探讨川崎病（KD）所引起的冠状动脉扩张（CAD）以及冠状动脉瘤（CAA）的超声心动图特点.方法 用彩色多普勒超声心动图检测KD患儿冠状动脉开口和内径,并动态观察静脉免疫球蛋白治疗前后冠状动脉内径的变化情况.结果 本组46例KD患儿,41例患儿行超声心动图检查,合并CAD 12例,左冠状动脉（LCA）较右冠状动脉（RCA）更易受累及（P〈0.05）；CAA 4例,均为双侧冠状动脉病变,最大内径10 mm.治疗后6～18 d复查超声心动图,CAD组LCA较治疗前明显回缩（P〈0.05）,RCA内径无变化（P〉0.05）；CAA组LCA和RCA内径均无明显变化（P〉0.05）.对10例冠状动脉病变患儿进行随访,其中8例CAD冠状动脉内径均恢复正常,1例CAA冠状动脉病变加重,1例CAA完全恢复正常.结论 （1）在KD所引起的CAD中,LCA比RCA更易受累及,静脉免疫球蛋白治疗后短期内LCA明显回缩.（2）超声心动图是动态观察KD并发CAD和CAA的无创手段.Objective To evaluate the echocardiographic features of coronary artery dilation （CAD） and coronary artery aneurysms （CAA） in Kawasaki disease dynamically.Methods Echocardiography was performed in KD cases for measurement of the diameter of the coronary artery.Results Twelve CAD and four CAA were identified in forty-one patients.In CAD group,left coronary artery （LCA） is more susceptive to dilation than right coronary artery （RCA）（P〈0.05）.Both LCA and RCA were involved in CAA group,the maximum diameter of coronary artery is 10mm.Six to eighteen days after treatment,LCA were regressed significantly in CAD group（P〈0.05）,but the diameter of RCA in CAD group and coronary artery in CAA patients have no change（P〉0.05）.Ten coronary artery lesion patients were followed up,8 CAD cases regressed completely,1 CAA extended,the other CAA regressed completely.Conclusions In CAD group,LCA is more susceptive to dilation than RCA,but it regressed significantly in a short time after treatment.Echocardiography is a non-traumatic method to detect the coronary artery lesions in KD patients dynamically.
