Antenatal Diagnosis of Congenital Anomalies on Ultrasound Screening

Congenital fetal anomalies contribute to the global burden of disease in children. Various screening programs have been used for antenatal screening of these anomalies. Screening targets low risk population and is usually done in the second trimester though some are done at the mother’s first antenatal visit especially in resource constrained setting. Mother’s who have had a previous pregnancy with congenital anomaly are given targeted elaborate screening. Early diagnosis of this anomalies can lead to early intervention and better outcomes. Diagnosis of the malformations also leads to clinical decision making on mode of delivery thereby avoiding birth related trauma to the mother and the baby. In case of lethal congenital anomalies early diagnosis aids in clinical decision making on the management of the pregnancy.
