Abstract
Appropriate knowledge of gestational age is very essential for management of pregnancy, particularly for
determination of viability in preterm labour, interpretation of biochemical serum screening test or for counseling patients
regarding the option of pregnancy termination. Various ultrasonic fetal parameter like gestational sac mean diameter,
crown- rump length (CRL), biparietal diameter (BPD), Head circumference (HC), abdominal circumference(AC) and
femur length(FL) are used for determination of gestational age. This study is being undertaken to find out other
ultrasonic fetal parameter like fetal foot length (FTL) for determination of gestational age more accurately. In this study
ultrasonic measurement of fetal foot length was done in 500 antenatal cases from 20 to 40 weeks of gestation, calculated
from the first day of last menstrual period. In this study we found that, there is linear increase in the fetal foot length with
increase in the gestational age and the correlation is significant with r value of 0.97. From our study we can conclude that
fetal foot length is a reliable ultrasonic parameter for assessment of gestational age.
