摘　　要：目的：探讨多层螺旋 CT（MSCT）在小儿复杂先天性心脏病（简称先心病）的诊断价值。方法收集41例临床诊断为先心病的病例,均行 MSCT、超声心动图（UCG）检查,20例行心血管造影（CAG）检查,41例经手术证实。将术前 MSCT、UCG、CAG心脏检查诊断结果与手术诊断结果进行比较。结果手术证实225处畸形；心内畸形115处,MSCT、UCG、CAG 准确诊断率为92.2%、99.1%、74.4%；心外畸形110处,MSCT、UCG、CAG 正确诊断率为98.2%、84.5%、96.2%；MSCT、UCG 联合应用正确诊断224处,诊断符合率99.6%；MSCT 对先心病心外畸形的检出高于 UCG（χ2=12.962,P〈0.05）,差异有显著统计学意义。结论 MSCT 对先心病诊断准确率较高,MSCT 与UCG 联合应用明显提高先心病先天畸形诊断的准确性。Objective To explore the value of multislice CT （MSCT）in the diagnosis of complex congenital heart disease （FCHD）in children.Methods 41 children cases with clinical diagnosis of congenital heart disease were collected randomly.All the children were examined with MSCT and ultrasonic cardiogram（UCG）examination,and 20 cases were examined with cadioangiography（CAG） check.All the cases were confirmed by surgery.The results of Preoperative MSCT,UCG and the CAG heart examination diagnosis were compared with surgical diagnosis results.Results Surgery confirmed 225 deformities and 1 1 5 intracardiac malformations.In the intracardiacmal malformations,the accurate diagnostic rates of MSCT,UCG,the CAG were 92.2%,99.1% and 74.4%,respectively;With surgery confirmed 110 heart malformations,the accurate diagnostic rates of MSCT,UCG,the CAG were 98.2%,84.5%,96.2%,respec-tively.The combined use of MSCT and UCG confirmed 224 correct diagnoses,the diagnosis coincidence rate reached 99.6%;The check accuracy of MSCT was highter than UCG in congenital heart disease with heart malformations（χ2 =12.962,P〈0.05）,The differences has statistical significance.Conclusion The check accuracy of MSCT is better in the diagnosis of congenital heart disease.The joint application of MSCT and UCG can obviously improve the accuracy of the diagnosis of congenital heart disease and congenital anoma-lies.
