摘　　要：目的:探讨影响早孕期(孕11~14周)胎儿心脏二维超声成像的可能因素。方法:回顾性收集2018年12月—2019年7月在本院接受早孕期胎儿超声检查的692例孕妇临床资料,均为单胎妊娠。采用上腹部横切面(UAT)、四腔心切面(4C)、左室流出道切面(LVOT)、右室流出道切面(RVOT)和三血管-气管切面(3VT)对胎儿心脏进行超声检查,观察并记录上述5个切面的显示情况,记录孕妇年龄、孕产史、胎儿顶臀径、孕妇体质指数、探头适度加压后孕妇的腹壁厚度和腹壁下陷深度,分析影响胎儿心脏二维超声成像的影响因素。结果:692例胎儿UAT、4C、LVOT、RVOT和3VT切面二维超声显示率分别为83.2%(576/692)、91.3%(632/692)、67.3%(466/692)和63.3%(438/692)、61.0%(422/693)。单因素分析,各切面显示组与未显示组在孕产史、胎儿顶臀径、孕妇体质指数、孕妇腹壁厚度及腹壁下陷深度均具有差异(P<0.05),而孕妇年龄未见差异(P>0.05)。多因素分析,胎儿顶臀径<64mm、孕妇腹壁厚度≥35mm及腹壁下陷深度<10mm均是早孕期胎儿心脏二维超声成像的影响因素(P<0.05)。结论:早孕期行胎儿心脏超声检查时要综合分析影响超声成像的各种因素,有针对性地改善相应因素的影响,以获取较清晰的超声图像,提高早孕期胎儿心脏畸形的产前检出率。Objective:To explore the influencing factors of two-dimensional ultrasound imaging of fetal heart during the first trimester of pregnancy(11-14 gestational weeks).Methods:The clinical data of 692 pregnant women with single pregnancy who had undergone ultrasound examination of fetal heart from December 2018 to July 2019 were collected retrospectively.The fetal heart was examined and recorded by high-definition color Doppler imaging to obtain the five views,which included upper abdominal transverse view(UAT),four-chamber view(4C),left and right ventricular outflow tracts(LVOT and RVOT),and three-vessel and trachea view(3VT).And the maternal age,history of pregnancy,fetal crown-rump length,maternal body mass index,maternal abdominal wall thickness,and the depth of the abdominal wall depression when moderately pressurized of these women were recorded.The influencing factors of two-dimensional ultrasound imaging of fetal heart were analyzed.Results:The visualization rate of UAT view,4C view,LVOT view,RVOT view,and 3VT view of 692 fetus were 83.2%(576/692),91.3%(632/692),67.3%(466/692),63.3%(438/692),and 61.0%(422/693),respectively.The unirariate analysis showed that there were significant different in the history of pregnancy,fetal rown-rump length,maternal body mass index,maternal abdominal wall thickness,and the depth of the abdominal wall depression between the women with visualization of the five views and the women without visualization of the five views(P<0.05),but there was no significant different in age of the women(P>0.05).The multivariate analysis showed that fetal rown-rump length less than 64 mm,maternal abdominal wall thickness≥35mm,and the depth of the abdominal wall depression less than 10mm were the influencing factors of two-dimensional ultrasound imaging of fetal heart during the first trimester of pregnancy(P<0.05).Conclusion:It is necessary to analyze various influencing factors of two-dimensional ultrasound imaging of fetal heart during the first trimester of pregnancy,and targeted to improve t
