双源CT在检测儿童川崎病冠状动脉损害中的应用

目的评价双源CT在检测儿童川崎病（KD）并冠状动脉损害（CAL）方面的临床应用价值。方法对15例确诊为KD并经心脏超声确诊合并CAL的患儿进一步行双源CT（DSCT）检查，观察其冠状动脉病变的程度和冠状动脉瘤的数目、位置、形态和大小，并和同期超声心动图进行比较分析。结果DSCT共检测到冠状动脉瘤43个，肿瘤最宽径1.55?cm，平均（0.65±0.47）cm，其中小冠状动脉瘤（＜0.4?cm）15个，中冠状动脉瘤（＜0.8?cm，≥0.4?cm）20个，巨大冠状动脉瘤（≥0.8?cm）8个。累及左冠状动脉21个，包括左冠主干9个，前降支近段4个，前降支中段5个，回旋支3个。累及右冠状动脉22个，包括右冠近段9个，右冠中段7个，右冠远段6个。另外，发现3处狭窄及2处血栓形成。而6个位于中远段的冠状动脉瘤、2处血栓及3处狭窄B超未能显示。结论DSCT能清晰显示川崎病患儿冠状动脉病变的情况，在显示局部冠状动脉狭窄和血栓形成方面明显优于经胸超声，可成为川崎病并冠状动脉瘤患儿诊断和随访的重要评估方法。

Dual source CT in detection of coronary artery lesions in children with kawasaki disease

Objective To evaluate the value of dual source CT(DSCT) in diagnosis of coronary artery lesions due to kawasaki disease in children.Methods Fifteen children with known kawasaki disease and coronary artery lesions confirmed by echocardiography underwent coronary artery angiography by DSCT.The number,location,shape and size of each coronary artery aneurysm was recorded and compared with those determined by echocardiography.Results There were 8 males and 7 females with a mean age of 3 years and 2 months(range ...
