- Abstract
Objective: To predict fetal growth restriction using transcerebellar diameter and abdominal circumference ratio (TCD/AC) in women with clinically diagnosed FGR. Materials and Methods: A prospective observational cohort study was conducted on women >28 weeks of gestation with clinically diagnosed fetal growth restriction, at the Tertiary care centre. Total 120 women were enrolled,over a period of 18 months,from December 2020 to July 2022 .Biometry was performed using ultrasonography and transcerebellar diameter and abdominal circumference ratio (TCD/AC) and head circumference and abdominal circumference ratio (HC/AC) were calculated. All women were followed up till delivery and fetomaternal outcome was recorded. After birth height, weight and ponderal index of the newborn were also noted. TCD/AC ratio was correlated with birth weight and ponderal index, for predicting FGR. TCD/AC ratio was also compared with routinely used HC/AC ratio for predicting FGR. Statistical Analysis: The final analysis was done with the use of Statistical Package for Social Sciences (SPSS) software, IBM manufacturer, Chicago, USA, version 21.0®. Results: A cut off value of TCD/AC >0.14 was found to have a sensitivity, specificity, PPV and NPV of 87.36%, 75.76%, 90.5% and 69.4% respectively with a diagnostic accuracy of 84.17%, in diagnosing FGR. There was a significant negative correlation between TCD/AC ratio with birth weight and ponderal index, with a correlation coefficient of 0.463 and 0.501 respectively. (p value < 0.001) TCD/AC was better predictor of fetal growth restriction with a diagnostic accuracy of 84.17% versus 40.83% with HC/AC. Significant positive correlation was observed between period of gestation (weeks) with transcerebellar diameter (mm),with correlation coefficient of 0.497 (p<0.001). Conclusions: TCD/AC ratio is an effective gestational age independent parameter to predict FGR on ultrasonography, with better diagnostic accuracy than routinely used HC/AC. Hence it should be performed for all antenatal women clinically suspected to have FGR.
