Early Detection of Fetal Malformation, a Long Distance Yet to Cover! Present Status and Potential of First Trimester Ultrasonography in Detection of Fetal Congenital Malformation in a Developing Country: Experience at a Tertiary Care Centre in India.

BACKGROUND

Early detection of malformation is tremendously improved with improvement in imaging technology. Yet in a developing country like India majority of pregnant women are not privileged to get timely diagnosis.

AIMS AND OBJECTIVES

To assess the present status and potential of first trimester ultrasonography in detection of fetal congenital structural malformations.

METHODOLOGY

This was a retrospective observational study conducted at Sanjay Gandhi Postgraduate Institute of Medical Sciences. All pregnant women had anomaly scan and women with fetal structural malformations were included.

RESULTS

Out of 4080 pregnant women undergoing ultrasound, 312 (7.6%) had fetal structural malformation. Out of 139 patients who were diagnosed after 20 weeks, 47 (33.8%) had fetal structural anomalies which could have been diagnosed before 12 weeks and 92 (66.1%) had fetal malformations which could have been diagnosed between 12 and 20 weeks.

CONCLUSION

The first trimester ultrasonography could have identified 50% of major structural defects compared to 1.6% in the present scenario. This focuses on the immense need of the hour to gear up for early diagnosis and timely intervention in the field of prenatal detection of congenital malformation.
