彩色室壁运动动态显示技术对川崎病室壁运动异常的研究

The study of color kinesis in the diagnosis of wall motion abnromaliies of Kawasaki disease

目的评价彩色室壁运动动态显示（CK）技术在川崎病早期诊断中的价值。方法20例川崎病患者应用CK技术定性分析左室各节段运动，且同期行二维超声检查。结果川崎病急性期CK技术检出17例节段性室壁运动异常，亚急性期18例，准确率分别为85％和90％。二维超声心动图检查：急性期冠状动内径正常10例，内径增宽10例；亚急性期冠状动脉内径正常4例，增宽16例；准确率分别为50％、80％。室壁运动异常节段对应的供血血管，左冠状动脉占55％，右冠动脉占45％，前降支占41％，回旋支占14％：结论CK技术能帮助检测川崎病患儿的左室室壁节段性运动异常，对评价病情和估测预后提供有价值的指标。

Objective To evaluate the value of color kinesis （CK） in the early diagnosis of Kawasaki disease. Methods Twenty patients with Kawasaki disease were examined by CK and two dimensional eehocardiography（2DE）, the results were analyzed. Results In 20 patients with Kawasaki disease, there were 17 cases with segmental wall motion abnormalities detected by CK in acute phase, and eighteen cases with segmental wall motion abnormalities detected in sub- acute phase. The accuracy rate was 85% and 90% at the acute phase and sub - acute phase, respectively. In 20 eases, there were 10 cases detected with normal diameter of CA,and 10 eases with CAD by 2DE in acute phase,4 cases found with normal diameter of CA and 16 cases with CAD in subacute phase. The detectable rate of CA abnormality were 50% and 80% hy two dimensional eehoeardiogram at the acute phase and sub - acute phase. Conclusion The CK can detect the left ventricular segmental wall motion abnormalities in patients with KD, and also can provide valuable indexes in evaluating the pathogenetic condition and estimating prognosis of patients
