Placental Thickness

Background: Gestational age and fetal weight estimation by ultrasound is the most effective and accurate method to date pregnancy. Ultrasound has been used to characterize placental position and morphologic changes. Placental thickness could be one additional parameter to assess gestational age and fetal weight. Objectives: This study aims to investigate the relationship between placental thickness with gestational age and fetal weight in third trimester of pregnancy in primigravida. Methodology: Prospective hospital based cross sectional study was conducted including 111 primigravida in third trimester with normal singleton pregnancies in Department of Radiology of Kathmandu Medical College Teaching Hospital from November 2018 to February 2019. Patients with known medical and obstetrical complications were excluded from the study. Placental thickness in millimeters was measured at the level of insertion of the umbilical cord. Pearson’s correlation analysis was used for analyzing variables and p-value <0.05 was considered statistically significant. Results: Mean age of participants was 28.3 ± 4.79 years. Posterior location of the placenta was most common (35%). Placental thickness correlated well with the gestational age and fetal weight. Pearson correlation coefficient was found to be 0.645 for placental thickness with gestational age and 0.598 for placental thickness with fetal weight. P-value was <0.001 in both, showing positive correlation of mentioned variables with placental thickness. Conclusion: Placental thickness can be a new and reliable parameter for estimation of gestational age and fetal weight. It can be routinely used during antenatal checkup.

Background: Gestational Age (GA) is one of the most imperative parameters required for proper management in pregnancy. Routinely GA is estimated by sonography utilising Biparietal Diameter (BPD), Femur Length (FL), Abdominal Circumference (AC) and Head Circumference (HC). In any case, these parameters have some limitations. Hence, there is need to find other parameters that may complement the established fetal biometric parameters in predicting GA. The objective of the present study was to assess placental thickness in second and third trimester pregnancies and its relationship with fetal gestational age and its role in detecting LBW and IUGRMethods: A cross sectional prospective study was carried out in three hundred pregnant women between 13 to 40 weeks of gestation, who came for routine antenatal sonography. Placental thickness was measured along with routine parameters. Placental thickness was measured at the level of umbilical cord insertion by two-dimensional ultrasonography.Results: Correlation between the GA by LMP and Placental thickness by ultrasound was done by using Karl Pearson's Correlation(r). The values were expressed as mean + standard deviation. Correlation between placental thickness and gestational age was statistically significant as p value is <0.01. Placental thickness measured in millimetres increases with gestational age in second and third trimester.Conclusions: The correlation between the placental thickness and gestational age was linear and direct. Therefore, Placental thickness is used as a predictor for estimation of gestational age of the fetus in cases where LMP is not known and in detecting developing IUGR and low birth weight.

Background: Knowledge of gestational age (GA) is important because it affects clinical management in many ways. Ultrasonography has provided a safe and noninvasive means of dating a pregnancy. The purpose of the present study is to assess the relationship of placental thickness with gestational age and to compare it with other sonographic parameters used to estimate gestational age. Subjects and Methods: The study included 242 normal pregnant women who knew their last menstrual period (LMP). After taking consent, all the women underwent an ultrasound examination. During the scan, besides measuring routine biometric parameters, Placental thickness at the cord insertion was also measured. A retrospective study was designated to test the hypothesis that placental thickness in an age dependant variable and hence can predict gestational age. In the end, the predicted gestational age by placental thickness was compared with gestational age as determined by other sonographic parameters. Results: Placental thickness showed a linear progression in relation to the menstrual age. The correlation coefficient was found to be 0.86(p<0.001). The regression equation was formulated by regressing gestational age on the measured placental thickness. The correlation coefficient between GA-LMP and GA-USG was 0.92 as compared to 0.86 between GA-LMP and GA-PT. The standard error for other USG parameters was +2.32 compared to +2.96 for placental thickness. Conclusion: Placental thickness being a fusion of menstrual age, can be used to predict the gestational age by using the regression formula. Gestational age calculated by other USG parameters is closer to menstrual age as compared to that by placental thickness. The prediction interval was slightly more when the placental thickness was used instead of other USG parameters. Placental thickness is a good alternative parameter for predicting gestational age in the second and third trimester.

Background: Throughout the fourth week of embryonic development the umbilical cord (UC) is formed, which corresponds to the fifth to the twelfth weeks of gestation. Fetuses with intrauterine growth restriction (IUGR) have leaner UCs than fetuses of appropriate gestational age do, and the caliber of the umbilical vein decreases significantly, resulting in a worsening of the Doppler parameters of the umbilical artery in the mother. The goal of this study was to evaluate the significance of sonographic UC diameter in determining gestational age in third trimester in pregnant women. Methods: We conducted a comparative cross-sectional research on 300 pregnant women aged range between (20-35) years, singleton gestation, gestational age (3rd) trimester estimated from antenatal mothers last menstrual period (LMP), viable fetus, presenting to obstetrics and gynecology department at Tanta university hospital. Results: Highly statistically significant positive correlation between UC diameter and gestational age, BPD, FL, AC, AFI, and estimated fetal weight was found. The increase in UC diameter was positively and significantly correlated with the increase in gestational age and estimated fetal weight, indicating that those who have prolonged gestational age and estimated fetal weight are more likely to have wider UC diameter. Conclusions: The UC diameter (UCD) has the potential to be a valuable indicator of fetal growth, well-being, and perinatal outcome. Sonographic measurement of UC diameter could be an efficient method of measuring fetal growth and predicting gestational age (GA), particularly between 28-40 weeks GA. It is possible that abnormal UC diameter can be a strong indicator to identify antenatal mothers at risk for IUFD and poor fetal outcomes.

Background: Gestational age is estimated by last menstrual period. Many women are unaware of their last menstrual period due to irregular menses, conception in lactation amenorrhea and due to illiteracy. The best possible ante partum care and successful labor outcome always revolve around the accurate knowledge of gestational age determination, and is an important component of antenatal care Methods: This was a prospective observational study conducted in department of obstetrics and gynecology on 200 pregnant women in second and third trimester with singleton live fetus at Mahila chikitsalay, S.M.S. medical college, Jaipur, from June 2018 to December 2019. All women were subjected to USG for estimation of gestational age by placental thickness (measured at the level of umbilical cord insertion). Results: Mean placental thickness show linear positive correlation with head circumference (HC). (r=0.960, p<0.0001).Mean placental thickness show linear positive correlation with abdominal circumference (AC). (r=0.948,p<0.0001). Mean placental thickness show positive correlation with FL both have linear correlation(r=0.946,<0.0001). Mean placental thickness show linear positive correlation with estimated fetal weight (EFW). (r=0.926,p<0.0001) Conclusion: All fetal parameter FL, HC, EFW, BPD, AC and gestational age showing positive correlation with placental thickness. All parameter have linear relationship with placental thickness. Correlation may be different with different type of parameter. Keywords: Ultrasonography (USG), Placental thickness, Gestation age.
