Objective To analyze the echocardiographic data of incomplete Kawasaki disease in children and infants, so as to pro? vide basis for clinicians to diagnose and treat the disease early to reduce the missed diagnosis and misdiagnosis of the disease.Meth? ods One hundred and twenty-eight children with incomplete Kawasaki disease (iKD) treated in Chengdu Women's and Children's Central Hospital, School of Medicine, University of Electronic Science and Technology of China from January 2019 to April 2021 were retrospectively selected as the observation group, and 297 children with typical Kawasaki disease (cKD) treated in our hospital in the same period were selected as the control group. The ultrasonic cardiogram (UCG) and the inflammatory indexes such as blood leukocyte(WBC), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and platelet (PLT) were compared between the two groups.Re?sults Among 425 children with KD, 128 cases (31.1%) had iKD and 297 cases (69.9%) had cKD. There were 121 cases (28.5%) of coronary artery dilatation in all children with KD, including 40 cases (32.3%) in iKD group and 78 cases (27.3%) in cKD group. There were significant differences in gender, left main coronary artery (LMCA), left anterior descending artery (LDA), circumflex branch (LCX), right coronary artery (RCA), middle RCA, mitral regurgitation (MR), tricuspid regurgitation (TR), rough coronary wall and CRP(P<0.05). There were significant differences in coronary artery dilation, LMCA, LDA, RCA, middle RCA, Mr, TR and rough coronary artery wall of iKD group (P<0.05). There were significant differences in coronary artery dilatation, gender, LMCA, LDA, LCX, RCA,middle RCA, Mr and rough coronary artery wall of cKD group (P<0.05). There were significant differences in coronary artery dilatation,MR, TR, rough coronary artery wall and PLT between iKD group and cKD group (P<0.05).Conclusions The main manifestations of UCG in children with iKD are coronary artery dilation, MR, TR, rough wall of coronary artery, and significant increase of laboratory in?flammatory index platelets. UCG can detect the changes of coronary artery wall and whether there is reflux in valves earlier and in time,and can provide better evidence for clinical diagnosis. |
