Foetal Age Assessment From Femur Length And Biparietal Diameter In Warri, South-south Nigeria.
Keywords:Foetal age estimation, menstrual period, biparietal diameter, femur length, sonography.
Introduction: Femur length (FL) and biparietal diameter (BPD) are among the foetal biometric parameters used to estimate the gestational age (GA) of the foetus.
Aim: The aim of this study was to determine the correlation of ultrasound generated gestational age (GA) by measuring FL and BPD with the last menstrual period (LMP) in Warri, South-South Nigeria.
Materials and Methods: Two hundred and thirteen (213) pregnant women who fulfilled the inclusion criteria were recruited into the study. The ultrasound scan measurements of FL and BPD were done in accordance with standard practice. Data were analysed using SPSS 20. Pearson's correlation was used to determine the relationship of GA based on LMP with FL and BPD. T-test was used to determine the differences between the mean GA from LMP, FL and BPD. P value <0.05 was considered significant.
Results: At 12th weeks, calculated GA (from LMP) was 12.43 weeks and mean FL was 12.74mm corresponding with USS GA of 14.11weeks, while mean BPD was 27.43mm corresponding to USS GA of 14.82 weeks. In both second and third trimesters, there were significant positive correlations between, GA based on FL and LMP; GA based on FL and FL; GA based on BPD and LMP; GA based on BPD and BPD; and GA based on FL and BPD. In the second trimester, the mean GAs based on FL and BPD were significantly higher than that based on LMP, but there was no significant difference between the mean GAs based on FL and BPD. In the third trimester, there was no significant differences in the mean GAs between FL and LMP, BPD and LMP, and FL and BPD.
Conclusion: FL and BPD increase as the foetal age increases. This study will be of relevance in obstetrics and gynaecology, and in forensic medical practice.
