CT、超声心动图在小儿川崎病冠状动脉病变患者心功能评估中的价值对比

目的分析CT、超声心动图在小儿川崎病冠状动脉病变患者心功能评估中的价值。方法回顾分析,收集本院2017年9月至2019年10月收治的69例小儿川崎病患者临床资料为研究对象,均进行CT、超声心动图检查。对患者所得超声、CT图像进行分析,了解CT、超声心动图检查对患者心功能以及冠状动脉主干直径评估情况。结果CT、超声心动图检查对患者LVEDV、LVSV、LVESV、LVEF值评估比较差异无统计学意义(P>0.05);CT、超声心动图检查测定患者RCA、LM值比较无差异(P>0.05),超声心动图检查:28.98%(20/69)存在冠脉扩张,21.73%(15/69)患者累及冠脉,其中左、右冠脉分别占46.66%(7/15)、53.33%(8/15),无狭窄以及钙化情况出现。CT检查:36.23%(25/69)有冠脉损伤的情况出现,47.82%(33/69)患者累及冠脉,其中左、右冠脉分别占54.54%(18/33),45.45%(15/33),有4例患者存在全程扩张呈串珠样改变,狭窄、钙化及狭窄合并钙化情况3例。结论CT、超声心动图均可有效评估小儿川崎病冠状动脉病变患者心功能情况,但CT检查对于中、远端病变诊断有明显优势,在临床上两者结合使用,可提高临床诊断价值。

C omparison on Value of CT and Echocardiography in the Evaluation of Cardiac Function in Children with Coronary Artery Disease of Kawasaki Disease

Objective To analyze the value of CT and echocardiography in the evaluation of cardiac function in children with coronary artery disease of Kawasaki disease.Methods The clinical data of 69 children with Kawasaki disease treated in our hospital from September 2017 to October 2019 were collected and retrospectively analyzed.All patients were examined by CT and echocardiography.The ultrasound and CT images of the patients were analyzed to understand the assessment of cardiac function and coronary artery diameter by CT and echocardiography.Results There was no significant difference between CT and echocardiography in the evaluation of patients'LVEDV,LVSV,LVESV,and LVEF values(P>0.05).CT and echocardiography showed no difference in the determination of RCA and LM values of patients(P>0.05).Echocardiography:28.98%(20/69)patients had coronary artery dilation,21.73%(15/69)patients had involvement of coronary artery,in which the involvement of left and right coronary arteries accounted for 46.66%(7/15)and 53.33%(8/15)respectively,no stenosis and calcification occurred.CT examination:36.23%patients(25/69)showed coronary artery injury,47.82%(33/69)patients were involved coronary artery,in which the involvement of left and right coronary artery accounted for 54.54%(18/33)and 45.45%(15/33),respectively.4 patients had bead-like changes throughout the course of dilation,and 3 patients had stenosis,calcification,and stenosis with calcification.Conclusion Both CT and echocardiography can effectively evaluate the cardiac function of patients with coronary artery disease in children with Kawasaki disease.However,CT examination has obvious advantages in the diagnosis of middle and distal lesions.The combination of them in clinic can increase the value of clinical diagnosis.
