探讨山南市妇幼保健院开展胎儿系统超声筛查的效果及意义。

回顾性分析2016—2021年在山南市妇幼保健院行产前超声筛查的孕11~40周孕妇的资料，得出开展胎儿系统超声筛查后产前超声筛查数、中孕期胎儿系统超声筛查数、中孕期系统超声占产前超声筛查总数比例，超声检出胎儿异常数、胎儿异常超声检出率、检出孕周、病种分布排序等情况。

开展胎儿系统超声筛查后，产前超声筛查数、中孕期系统超声筛查数、中孕期系统超声占产前超声筛查总数比例、胎儿异常检出数及胎儿异常检出率，均呈不同程度的增长；胎儿异常产前超声检出率由0.39%上升至1.03%；早孕期（11~13⁺⁶周）及中孕早期（14~17⁺⁶周）产前超声检出胎儿异常从无到有，且占比呈逐年增加趋势；附属物异常仍排在首位；胎儿异常病种由6种增加至34种。单脐动脉和右锁骨下动脉迷走占所有检出胎儿异常的40.16%。

开展规范的胎儿系统超声筛查可让更多孕妇在孕期接受超声筛查，显著提高胎儿异常检出率，减少胎儿异常出生。

To explore the effect of implementing fetal systemic ultrasound screening in Material and Child Health Hospital of Shannan.

The data of pregnant women at 11-40 gestational weeks who received prenatal ultrasound examination during 2016—2021 at Material and Child Health Hospital of Shannan were retrospectively analyzed. The change in the number of pregnant women receiving prenatal ultrasound screening, the number of pregnant women receiving fetal systemic ultrasound screening in the mid-trimester, the ratio of the number of pregnant women receiving fetal systemic ultrasound screening in the mid-trimester to that of pregnant women receiving prenatal ultrasound screening, the number of fetal abnormalities detected by prenatal ultrasound, the detection rate of fetal abnormalities by prenatal ultrasound, the gestation weeks when fetal abnormalities were detected, and the ranking and distribution of fetal abnormalities after implementing the fetal systemic ultrasound screening were then analyzed.

After implementing the fetal systemic ultrasound screening, the number of pregnant women receiving prenatal ultrasound screening, the number of pregnant women receiving fetal systemic ultrasound screening in the mid-trimester, the ratio of the number of pregnant women receiving fetal systemic ultrasound screening in the mid-trimester to that of pregnant women receiving prenatal ultrasound screening, and the number and detection rate of fetal abnormalities detected by prenatal ultrasound all increased. The detection rate of fetal abnormalities by prenatal ultrasound increased to 1.03% from 0.39%. The number of fetal abnormalities detected by prenatal ultrasound in the first trimester (11-13⁺⁶ weeks) and the early mid-trimester (14-17⁺⁶ weeks) increased from zero to 12, and showed an increasing trend year by year; and appendage abnormalities still ranked first. The type of fetal abnormalities increased from 6 to 34. Single umbilical artery (SUA) and aberrant right subclavicular artery (ARSA) accounted for 40.16% of all fetal abnormalities detected by prenatal ultrasound.

Implementing the standardized fetal systemic ultrasound screening could make more pregnant women to receive the prenatal ultrasound screening, improve the detection rate of fetal abnormalities, and reduce the incidence of fetal abnormalities.
