The clinical application value of fetal system ultrasonography in screening fetal malformation
Objective To explore the application value of fetal system ultrasonography in screening fetal malformation. Methods Clinical data of 850 pregnant women who underwent prenatal fetal ultrasonography were retrospectively analyzed,and color Doppler ultrasonography was applied for screening and diagnosis of fetal malformation,and the accuracy of fetal system ultrasonography was statistically determined with postnatal results as the gold standard. Results A total of 18 cases of various types of malformations were detected in the postnatal follow-up of 850 pregnant women,with a detection rate of 2.12％ (18/850),including 4 cases of malformations in the central nervous system,5 cases of malformations in the urinary system,2 cases of malformations of the face,4 cases of malformations in the cardiac system,2 cases of malformations in the limb-skeletal system,and 1 case of malformations in the digestive system. A total of 15 cases of malformations were detected by ultrasonography,with a detection rate of 83.33％(15/18),and 3 cases were missed,the missed diagnosis rate was 16.67％(3/18). All were confirmed by postmortem examination after normal delivery or induced labor. Time of malformation detection:11 cases of fetal malformation were detected at 18-24 weeks of pregnancy,accounting for 61.11％;6 cases were detected at 25-36 weeks of pregnancy,accounting for 33.33％;and 1 case was detected after 36 weeks of pregnancy,accounting for 5.56％. Conclusion Fetal system ultrasonography is an important means to screen and diagnose fetal malformations. Standardized systematic ultrasonography during pregnancy can reduce the rate of fetal birth defects by providing prenatal diagnosis of fetal malformations and guiding the clinic to develop further intervention plans.
