“…Similar to present study, Uikey et al and Prasad and Likitha similar to present study found BPD and TCD to be better predictors of gestational age as compared to other fetal biometric parameters. 4,16 In present study, difference in estimated and actual gestational ages as estimated by TCD were more precise for third trimester >28 weeks as compared to those in 16-28 weeks of pregnancy, however, overall estimates strongly correlated with actual gestational age (r=0.984) and thus showed statistically no significant difference between actual and estimated age. Thus, for third trimester pregnancy, TCD was found to be a better predictor of gestational age in a pregnancy having combination of both normal as well as IUGR cases.…”

Background: Gestational age is the common term used during pregnancy to describe how far advanced is the pregnancy. In the second and third trimesters, estimation of gestational age is accomplished by measuring the biparietal diameter, head circumference, abdominal circumference, and femur length. The transverse cerebellar diameter (TCD) may serve as a reliable predictor of gestational age (GA) of the fetus and a standard against which aberrations in other fetal parameters can be compared.Methods: The study was conducted in the tertiary care teaching hospital from July 2016 to March 2017. 200 pregnant women of gestational age 15-40 weeks of pregnancy referred from Dept of Obs and Gynae for antenatal scan comprised our study sample.Results: Age of women ranged from 18 to 43 years with maximum number of patients aged 26-30 years. Maximum cases with clinical suspicion for IUGR were in gestational age >36-40 weeks (50%). Evaluation of difference in actual and estimated gestational age between normal and actual gestational age showed that for normal pregnancy as well as in IUGR pregnancies mean difference between estimated and actual gestational age was minimum in TCD followed by other established parameters.Conclusions: TCD being a stable parameter irrespective of growth status of fetus, provides a basis for its usefulness as a ratio to predict IUGR and other perainatal outcomes as used in several studies. Thus, despite not being a direct marker for IUGR it can serve as a surrogate marker for detection of IUGR and another adverse perinatal outcome.

“…Our results were also in agreement with Uikey et al 23 study which indicated the correlation of TCD with BPD was (r = 0.960), with HC (r = 0.979), with AC (r = 0.980) and with FL (r = 0.976). The same study revealed that trans-cerebellar diameter to be a precise measurement in the detection of gestational age during second and third trimester of pregnancy without being affected by abnormal fetal growth patterns.…”

“…10 Uikey et al, and Prasad found BPD and TCD to be better predictors of GA as compared to other fetal biometric parameters. 11,12 Similar study by Dashottar S et al found difference in estimated and actual GA as estimated by TCD were more precise for third trimester >28 weeks as compared to 16 to 27 weeks of pregnancy, however, overall estimates strongly correlated with actual gestational age (r=0.984) and thus showed statistically no significant difference between actual and estimated GA thus this study also support that third trimester pregnancy ,TCD was a better predictor of GA in pregnancy having combination of both normal as well as IUGR cases. 13 Similar to present study, the role of TCD in prediction of accurate GA in normal as well as IUGR pregnancy has also been highlighted in several previous studies.…”

Background: Assessment of fetal gestational age (GA) is an essential part of obstetric USG. Accurate knowledge of fetal GA is important to facilitate the best possible prenatal care and successful pregnancy outcome. For the estimation of GA the commonly used parameters in third trimester are:- BPD, HC, AC and FL. As all these parameters are affected by fetal growth disorders and fetal position. TCD can be used as another parameter for the estimation of GA in growth restricted fetuses.Methods: This study was conducted at Mahila Chikitsalaya Sanganeri Gate; SMS Medical College Jaipur from July 2005 to September 2006. A total of 80 pregnant women in third trimester with singleton pregnancy including 40 pregnant women with known cases of IUGR and 40 AGA fetuses were studied for TCD measure.Results: Correlation coefficient between TCD and gestational age was highly significant and no significant difference was found in TCD of AGA and IUGR fetuses.Conclusions: TCD measurement can be used as more reliable parameter for accurate estimation of gestational age in IUGR fetuses in third trimester.
