Abstract

Background: Accurately determining the gestational age of a pregnant woman is crucial for optimizing the care she receives and the health of her unborn child. Despite the fact that several biometric markers were shown to be reliable in estimating gestational age, it was discovered that these estimates were impacted by aberrant fetal growth patterns. Aim of the study: Comparing transcerebellar diameter to head circumference for determining gestational age in the third trimester. Patients and methods: One hundred fifty pregnant women were observed during their third trimester. Patients were recruited from the obstetrics and gynecology outpatient clinics and causalities at Al-Azhar University Hospital, Kafr Shokr Central Hospital, and private specialized U/S units. Results: The current research showed that the mean of TCD (mm) was 31mm in 28-32 week, 35mm in 32-36 week and 39,4mm in 36-40week. Additionally, the mean HC (cm) was 26,5+/-0,69cm in 28-32week , 29,3+/-0,6in 32-36week and 31,7 +/- 37cm in 36-40 week. The mean gestational age by LMP was 33.92 with minimum 28 and maximum 40 week, the mean gestational age by TCD was 33.74 with minimum 28 and maximum 40 week, and the mean gestational age by head circumference was 33.56 with minimum 28 and maximum 40 week. Weeks by TCD and Weeks by LMP had a statistically significant positive relationship. (P value
