摘　　要：目的应用胎儿超声心动图测量McGoon指数(MGI),探讨不同孕龄的胎儿及不同肺血流量状态下MGI的变化。方法回顾性选取2020年6月至2021年8月在浙江大学医学院附属邵逸夫医院超声科接受超声心动图检查的胎儿。超声心动图检查未见异常的218例胎儿为正常组(依据孕龄分为4个亚组);胎儿超声心动图考虑肺动脉血流减少或闭锁的先天性心脏病胎儿66例(病例组1),考虑主动脉血流减少或离断胎儿19例(病例组2)。超声心动图测量胎儿的MGI,比较分析各组之间测量结果的差异。结果正常对照组不同孕龄的4个亚组间(18~21^(+6)周、22~25^(+6)周、26~29^(+6)周、30~33^(+6)周)MGI分别为1.39±0.35、1.38±0.20、1.38±0.21、1.40±0.19,差异无统计学意义(P>0.05)。正常对照组MGI为1.38±0.22;肺动脉血流减少或闭锁组MGI为1.16±0.19,低于其他2组,差异有统计学意义(P<0.05);主动脉血流减少或离断组MGI为1.42±0.25,与正常组比较差异无统计学意义(P>0.05)。结论孕18~33^(+6)周阶段正常胎儿MGI相对恒定,不随孕龄的增加而改变;超声心动图定量测量胎儿MGI可评价不同先天性心脏病胎儿的肺血流量,一定程度上反映肺血管发育情况。Objective To investigate the dynamic changes of McGoon index(MGI)in fetuses with different gestational weeks or different pulmonary blood flow patterns by fetal echocardiography.Methods Fetuses who underwent echocardioimagedata examination at the Department of Diagnostic Ultrasound&Echocardiography,Sir Run Run Shaw Hospital,Zhejiang University School of Medicine from June 2020 to August 2021 were included,of whom 218 with no abnormalities detected by echocardiography were included in a normal group(further subdivided into 4 subgroups based on gestational age),66 had decreased pulmonary blood flow or pulmonary atresia(case group 1),and 19 had decreased aortic blood flow or interruption of the aortic arch(case group 2).MGI was measured and calculated by echocardiography,and its differences among groups were compared.Results MGI in the four subgroups of the normal control group(18-21^(+6)weeks,22-25^(+6)weeks,26-29^(+6)weeks,and 30-33^(+6)weeks)was(1.39±0.35),(1.38±0.20),(1.38±0.21),and(1.40±0.19),respectively,and the difference among the four subgroups was not statistically significant(P>0.05).MGI in the normal control group was(1.38±0.22).MGI in case group 1 was(1.16±0.19),significantly lower than that of the other two groups(P<0.05).MGI in case group 2 was(1.42±0.25),which was comparable to that of the normal control group(P>0.05).Conclusions MGI in normal fetuses with a gestational age of 18-33^(+6)weeks is constant,and it does not change with increasing gestational age.Quantitative measurement of fetal MGI by echocardiography can evaluate the pulmonary blood flow of fetuses with different congenital heart diseases,reflecting,to some extent,the development of pulmonary blood vessels.
