Accuracy of Fetal Transcerebellar diameter in evaluation of Fetal gestational age in Egyptian pregnant women

Abstract

his study was performed to evaluate the accuracy of TCD in singleton gestation as an accurate parameter compared to other parameters (Fl, BPD, AC) and Hadlock equation in determining gestational age in normal pregnant woman and normal fetus. The study was conducted on 100 pregnant women between 30 to 40 weeks of gestational age who attended the antenatal care in the outpatient clinic at Ain Shams university maternity hospital in the period from September 2018 to September 2019. The whole patients were fulfilling the inclusion and exclusion criteria and counseled for the study and then ultrasound examination and measurements of the Transcerebellar diameter, Biparietal diameter, Abdominal circumference and femur length were recorded. Data were coded and entered using IBM SPSS statistics (Statistical Package for Social Sciences) software version 18.0, IBM Corp., Chicago, USA, 2009. The percentages of accurate assessment of gestational age by the three measurements (TCD, BPD, FL and AC) and gestational age by Hadlock within 3 days and within 1 week from the actual gestational age measured by LMP were calculated. Then comparison between
