目的：探讨128层螺旋CT对完全性大动脉转位（CTGA）的诊断价值。方法：回顾性分析27例完全性大动脉转位的128层螺旋CT和经胸壁超声心动图（TTE）资料，并与手术结果作对照。结果：手术证实单纯性CTGA 19例，心脏畸形有46处，128层螺旋 CT 和 TTE 的诊断符合率分别为82％和91％，两者差异无统计学意义（χ2＝1．533，P＞0．05）；复合性CTGA有8例，心脏畸形有34处，128层螺旋CT和TTE的诊断符合率是94％和91％，两者差异无统计学意义（χ2＝0．216，P＞0．05）。对CTGA的大动脉位置关系判断：128层螺旋CT与TTE的符合率分别是100％和81％，两者差异有统计学意义（χ2＝5．510，P＜0．05）。对CTGA冠状动脉解剖类型的判断：128层螺旋CT和TTE的符合率分别是81％和45％，两者差异有统计学意义（χ2＝7．941，P＜0．05）。结论：128层螺旋CT可准确诊断CTGA心内及心外异常结构，对判断大动脉位置关系和冠状动脉解剖类型较TTE更准确，可为手术方式的选择提供重要的影像学依据。

Objective:To investigate the value of 128-slice spiral CT in the diagnosis of complete transposition of great arteries (CTGA).Methods:The imaging materials of CT and transthoracic echocardiography (TTE)in 27 pediatric patients with surgery proven CTGA were analyzed retrospectively,and correlated with surgical findings.Results:Among the 27 cases with CTGA,there were 19 cases of surgery proven simple type CTGA,complicated with 46 cardiac deformities.The diag-nostic accuracy of 128-slice spiral CT and TTE was 82%and 91% respectively,with no statistic difference (χ2= 1.533,P>0.05).8 cases were surgery proven as complex type CTGA,complicated with 34 cardiac deformities.The diagnosis accuracy of 128-slice spiral CT and TTE was 94% and 91% respectively,with no statistic difference (χ2= 0.216,P>0.05).In jud-ging the position relationship of the two great arteries,the accuracy of 128-slice spiral CT and TTE was 100% and 81% re-spectively,with significant statistic difference (χ2= 5.510,P<0.05).In the evaluation of coronary artery anatomy typing of CTGA,the accuracy of 128-slice spiral CT and TTE was 81% and 45% respectively,with significant statistic difference (χ2= 7.941,P<0.05).Conclusion:128-slice spiral CT can accurately diagnose intra- and extra-cardiac deformities in CT-GA.It is also more accurate in judging the position relationship of the two great arteries and typing for coronary anatomy which are superior than TTE and can provide important information for surgery planning.
