Abstract

Background: A fetus whose estimated weight is below the 10th percentile for its gestational age (GA) is the most often utilized definition of IUGR. A newborn with asymmetric growth limitation will have a smaller abdomen than head. Gestational age affects several of the factors for IUGR identification. An important metric that is independent of gestational age is the transcerebellar diameter to abdominal circumference ratio (TCD/AC). Both the volume of the subcutaneous plane and the size of the liver are reflected by AC. Aim: To measure fetus growth restriction and to choose a cut-off value for TCD/AC to evaluate the reliability of TCD/AC in the identification of Asymmetric IUGR. Subject and Methods: 100 pregnant women after 28 weeks of gestation, 50 of them with IUGR fetus (estimated fetus weight < 10th percentile for the age) as the study group and 50 of them with fetuses of normal fetal weight regarding to gestational age as the control group. Results: When compared to the control group, there was a considerable rise in the cases group's FBG, TCD, TCD/AC ratio, and UA R index. When compared to the control group, there was a considerable decrease in AC, fetal weight, and amniotic fluid in the case group. TCD/AC and asymmetric IUGR showed a strong relationship and linkage. Conclusion: TCD/AC and HC/AC, two morphometric ratios that were GA independently measures, may both be used to accurately diagnose IUGR. When predicting asymmetric IUGR, TCD/AC ratio outperformed HC/AC ratio in terms of diagnostic validity and accuracy.
