Abstract

Background: Ultrasonographic assessment of gestational age by using different foetal parameter such as BPD, FL, AC are highly reliable in first and second trimester in pregnancy. In third trimester reliability of any single parameter has limitations.

Methods: This was a hospital based comparative cross-sectional study done in the Department of Obstetrics and Gynaecology, S.M.S. Medical College and attached hospitals, Jaipur, Rajasthan. The period of study was from June 2018 to October 2019.

Results: The mean TCD at 15 weeks and 40 weeks was 15.00 ± 0.00mm and 53.33±1.155mm respectively. The mean BPD at 16 weeks and 40 weeks was 33.50±0.70mm and 93±1.528mm respectively. The mean HC at 15 weeks and 40 weeks was 111.00±1,41mm and 340±2.00mm respectively. The mean FL at 15 weeks and 40 weeks was 18.50±0.70mm and 77.67±1.528mm respectively. The mean AC at 15 weeks and 40 weeks was 99.00±1.41mm and 365.33±8.32mm respectively.

Conclusion:  We conclude that foetal transcerebellar diameter can thus be used as an alternative foetal parameter to assess gestational age and can be used in cases of wrong dates or when other routine parameters are not conclusive or did not accurately predict gestational age for e.g. in cases of hydrocephalus, brachycephaly, dolicocephaly, intrauterine growth restriction, achondroplasia or short limb dwarfism.
