多切面连续超声筛查法诊断胎儿颜面部畸形的临床价值

Clinical value of ultrasound diagnosis of fetal facial deformity with multi-plane continuous screening

目的分析胎儿颜面部畸形产前超声显示率偏低的原因,探讨多平面连续超声扫查法在显示胎儿颜面部畸形中的应用价值。方法将9240例产前超声筛查的孕妇随机分为常规超声筛查组4445例和多切面连续超声筛查组4795例,比较两组胎儿颜面部异常检出情况。结果9240例胎儿产后或引产后证实胎儿颜面部畸形31例(0.34%),40处畸形,发生于常规超声筛查组14例(0.31%),共15处,多切面连续超声筛查组17例(0.35%),共25处;两组胎儿颜面部畸形发生率比较差异无统计学意义。常规超声筛查组产前超声检出颜面部畸形5例,5处,多切面连续超声筛查组产前超声检出颜面部畸形14例,16处,两组比较差异有统计学意义(P<0.01)。结论多切面连续超声筛查可较为系统观察胎儿颜面部,有助于对胎儿颜面部畸形的检出。

Objective To analyze the causes of low prenatal ultrasonically display rate of partial fetal facial deformities,and to explore the application value of multi-plane continuous ultrasound scanning in the display of fetal facial deformities.Methods A total of 9240 pregnant women who underwent prenatal ultrasound screening by grouping randomly were divided into two groups:4445 in the routine ultrasound screening group,and 4795 in the multi-plane continuous ultrasound screening group.The detection rate of the fetal facial abnormality was compared between the two groups.Results Totally 9240 cases of postpartum or after induced labor confirmed 31 cases(0.34%)of fetal facial deformity,40 deformities.And the routine ultrasound screening set of facial malformations 14 cases(0.31%),15 deformities,multi-plane continuous ultrasound screening set of facial malformations 17 cases(0.35%),25 deformities.There was no significant difference in the incidence of fetal facial malformation between the two groups.Prenatal ultrasonography showed facial deformities in 5 cases,5 deformities in the routine ultrasound screening group,and 14 cases,16 deformities in the multi-plane continuous ultrasound screening group.The difference in prenatal ultrasonography showed statistically significant difference between the two groups(P<0.01).Conclusion Multi-plane continuous ultrasound for the observation of fetal facial can be more systematic observation,which is helpful for the detection of fetal facial malformations.
