| 目的 探讨实时三维超声技术在诊断胎儿矫正型大动脉转位(cTGA)中的应用价值。方法 回顾性分析14胎胎儿cTGA的资料。二维超声检查获取各诊断切面,并采用心脏三节段分析法进行分析。实时三维超声检查在四腔心切面上采集四维容积数据,利用时空影像关联(STIC)技术分析两条大动脉的位置关系。与产后超声心动图及尸体解剖结果对照,对两种方法诊断胎儿cTGA及合并畸形的准确率进行比较。结果 实时三维超声检查与常规二维超声检查诊断准确率分别为92.86%、71.43%,差异无统计学意义(χ2=2.19,P=0.14);实时三维超声检查时间明显短于常规二维超声,差异有统计学意义(t=10.23,P＜0.001)。结论 实时三维超声可快速、准确地诊断胎儿cTGA及其合并畸形,相对于二维超声有一定优势。 |

| Objective To assess the application value of real time three-dimensional (RT-3D) ultrasonography in diagnosis of fetal corrected transposition of the great arties (cTGA). Methods Data of 14 fetuses diagnosed as cTGA clinically were reviewed. With 2D ultrasonography, diagnosis views were obtained and then studied using cardiac three-section analytic method. With real time 3D (RT-3D) ultrasonography, volume datasets were acquired at the level of four chamber view, and spatio-temporal image correlation (STIC) was then used to analyze the relationship of the two great arties. Confirmed by infant echocardiography and the autopsy findings, the accuracy of RT-3D and 2D ultrasonography in evaluation of fetal cTGA and complications were compared. Results The accuracy rate of RT-3D and 2D ultrasonography in diagnosis of fetal cTGA was 92.86% and 71.43% (χ2=2.19, P=0.14). The procedure time of RT-3D ultrasonography was significantly shorter than that of 2D ultrasonography (t=10.23, P＜0.001). Conclusion RT-3D ultrasonography can evaluate fetal cTGA and its complications more quickly and exactly than conventional 2D ultrasonography. |
