摘　　要：目的探讨128层MSCT在新生儿复杂型先天性心脏病(ccHD)的应用价值。方法对我院手术证实的35例新生儿CCHD进行回顾性心电门控128层MSCT扫描,分析新生儿心脏CT检查特殊的扫描技术,并与超声心动图比较。结果所有新生儿均成功完成MSCT。心脏扫描。本组35例新生儿复杂型CHD中,MSCT共检出93个心内外结构异常,超声心动图则检出86个,两种检查方法对于显示畸形部位数目的差异没有统计学意义(P=0.205)。但超声比MSCT多发现3例房/室间隔缺损及2例肺动脉瓣狭窄,而MSCT比超声心动图多发现12例心外血管畸形。结论 MSCT回顾性心电门控扫描技术能较好评价新生儿复杂型CHD,弥补超声心动图对心外血管畸形显示能力低的缺点。Objective To evaluate of the application of 128-slice CT in complex congenital heart disease（CCHD）of neonates.Methods 35 neonates with CCHD underwent 128-slice CT using retrospective ECG-gating.The CT was compared with echocardiography.Results In 35 patients,there was no significant difference between CT（93）and echocardiography（86）for demonstrating intra- and extra-cardiac abnormalities（P=0.205）.Three ventricular/atria sepal defects and 2 pulmonary valvular sclerosis were depicted only on echocardiography whereas 12 extra-cardiac vascular abnormalities were seen only on CT.Conclusion Retrospective ECG-gated 128-slice CT complements echocardiography for evaluating extra-cardiac vascular abnormalities in CCHD.
