Abstract

Background: The management of antenatal care and the successful planning of an appropriate intervention or therapy depend greatly on the determination of gestational age (GA). When dates are ambiguous or there is a suspicion of intrauterine growth retardation, transverse cerebellar diameter (TCD) provides a significant advantage in predicting GA. Aim of the work: to compare TCD measurement to existing fetal biometric measures such as femur length (FL) and biparietal diameter (BPD) in order to evaluate the diagnostic accuracy of TCD measure in estimating GA throughout the second and third trimesters. Patients and methods: The obstetrics and gynecology department of El-Sheikh Zayed Al-Nahyan Hospital-Specialized Medical Center visited the outpatient clinic in order to get prenatal treatment. Sample size calculation produced from minimum 300 pregnant women in three groups (100 pregnant women in each group) were recruited from ultrasound evaluation (trans abdominal) via (Sonoscope S50), (Voloson GE), and (Toshiba), routine ultrasound obtained in about18 months, from November 2020 till May 2022. Results: The findings of the study demonstrated that TCD is more reliable than the BPD, and that there is a substantial statistical variation between the TCD and the BPD, as well as between the TCD and the FL, when calculating GA in the 2nd and 3rd trimesters. Conclusion: TCD is a more precise method than biparietal diameter for determining gestational age in the 2nd and 3rd trimesters of gestation. In the 2nd and 3rd trimesters, TCD and FL can be employed as a method to help determine gestational age.
