| ［摘要］ 目的 探讨胎儿心脏超声智能导航技术检查胎儿心脏先天性畸形的临床应用价值。方法 选择2018-07～2019-12于成都市第一人民医院经胎儿超声心动图检查诊断为胎儿心脏先天性畸形的单胎11例。于孕18.4～30.0（24.7±2.7）周应用胎儿心脏超声智能导航技术进行检查，分析先天性心脏畸形胎儿的心脏容积数据及9个胎儿心脏切面声像图表现，并与常规胎儿心脏超声的声像图进行对比。结果 11例心脏先天性畸形胎儿中血管环3例，共同动脉干3例，右心室双出口1例，左心发育不良综合征1例，肺动脉瓣狭窄1例，单纯室间隔缺损2例。11例均获取胎儿心脏容积数据，除1例胎儿的心脏容积数据因胎动特别明显致容积数据不稳定导致分析困难外，其余10例胎儿心脏容积数据可应用配套软件进行线下分析。胎儿心脏超声智能导航技术检查所呈现的9个胎儿心脏切面的声像图为灰阶图，无彩色血流图，无频谱图，可显示或部分显示胎儿心脏先天性畸形的相应异常声像。结论 应用胎儿心脏超声智能导航技术获取胎儿心脏容积数据成功率高，对有明显解剖结构异常的胎儿心脏先天性畸形可提供具有临床价值的诊断信息，但对需要彩色血流图和频谱信息才能作出诊断的部分心脏畸形所能提供的信息有限。 |

| ［Abstract］ Objective To explore the clinical application value of fetal heart ultrasound intelligent navigation technique in detecting fetal heart congenital malformations. Methods Eleven cases of singletons diagnosed with fetal heart congenital malformations by fetal echocardiography were selected in Chengdu First People′s Hospital from July 2018 to December 2019. The fetal heart ultrasound intelligent navigation technique was used for inspection at 18.4～30.0(24.7±2.7) weeks of pregnancy, and the heart volume data of the fetuses with congenital heart malformations and the sonographic appearances of 9 fetal heart sections were analyzed and compared with those of the conventional fetal cardiac ultrasound. Results Among the 11 fetuses with cardiac congenital malformations, there were 3 cases of vascular ring, 3 cases of truncus arteriosus, 1 case of double outlet right ventricle, 1 case of hypoplastic left heart syndrome, 1 case of pulmonary valve stenosis and 2 cases of simple ventricular septal defect. The fetal heart volume data were obtained in all the 11 cases. The fetal heart volume data of 1 case were unstable and difficult to analyze due to obvious fetal movement, while those of the other 10 cases can be analyzed offline using supporting software. The examination results of fetal heart ultrasound intelligent navigation technique showed that the sonograms of 9 fetal heart sections were grayscale images, no color blood flow imaging and no spectrogram, which could show or partially display the corresponding abnormal sonograms of the fetal heart congenital malformations. Conclusion The success rate of obtaining fetal heart volume data by fetal heart ultrasound intelligent navigation technique is high. It can provide clinically valuable diagnostic information for fetal heart congenital malformations with obvious anatomical abnormalities. However, it can provide limited information for some cardiac malformations which need color flow mapping and spectral information to diagnose. |
