Clinical Evaluation of Prenatal Ultrasonographic Screening for Fetal Abnormality

Objective To explore the clinical significance of prenatal ultrasonographic screening in detection of fetal defects.Method A total of 9,089 full term pregnant women during their 18～40 gestational weeks received real-time color Doppler ultrasonography to find out whether fetal congenital anomaly was present.Results In all the examined 9,089 pregnant women,133 cases with fetal anomalies were confirmed by post-natal evaluation or abortion.115 cases of fetus abnormality were found by color Doppler ultrasonography before birth.18 cases of fetus abnormality were missed in diagnosis.Conclusions A systemic prenatal ultrasonographic examination in the second-trimester is important for prenatal diagnosis of congenital malformations,which plays an important role in decreasing birth defects and improving the quality of new-born population.
