Background: The aim of the study was to exploring the application of placental thickness as a sonographic marker for determining gestational age among singleton pregnant mothers.Methods: This longitudinal, observational study was conducted in obstetrics and gynecology department and department of Radiology, Sri Venkateshwaraa Medical College and Hospital, Ariyur, Puducherry, in antenatal mothers of 11-40 weeks of gestation from 2018 to 2019. The study included 278 normal singleton pregnant women. The details regarding the socio-demographic variables, relevant clinical history and examination, laboratory investigations and ultrasound report containing gestational age, placental thickness measured at the level of cord insertion were documented in a proforma. The sonographic measurements were made using a grey scale real time ultrasound machine Siemens ACUSON x400 with a convex 2-5 mhz probe.Results: The study included 278 pregnant women with a mean age of 25.8±44 years. Majority of them were home makers (n=155, 55.7%) and educated (n=257, 92.4%) and primigravida(n=117, 57.9%).The position of the placenta in majority of the participants was posterior placed (71.6%). The mean gestational age of the studied antenatal women was 28.3±7.2 weeks as per ultrasonogram. Majority of the participants were younger aged between 20 to 30 years of age and very few teenage pregnancies. There was a significant correlation between the gestational age and placental thickness (p<0.001). There was a significant (p<0.001) correlation between placental thickness and femur length (r=0.972).Conclusions: The placental thickness showed significant positive correlation with the gestational age as measured by ultrasonogram. Hence it can be used as a parameter in determining the gestational age.

In Pregnancy

Objectives: The human placenta is the nourishing reservoir for the sustenance of the fetus and synthesizes a growth-stimulating hormone to enhance proper growth and maturation. The size or thickness of the placenta enlarges as the pregnancy progresses in age to attain a favorable state which can cope with the increasing fetal demands. Placental thickness (PT) is a reflector of fetal well-being, and it is related to fetal weight making it necessary to assess the influence of pregnancy-induced hypertension (PIH), a common pathology in pregnancy, on the placental size or thickness. The main objective of this research is to compare and evaluate the PT and fetal weight in PIH and normotensive pregnant women. Material and Methods: The study was a prospective cross-sectional case-controlled study done in the Radiology Department of the University of Calabar Teaching Hospital. During a 12 months study period, 200 singleton pregnant women (consisting of 100 pregnancy-induced hypertensives and 100 normotensive pregnant women) of between 20 and 40 weeks of gestation were enrolled in this study. The two groups were gestational age-matched. The PT was measured trans-abdominally using an ultrasound scan. Pearson’s correlation analysis was used to establish the degree of relationship between PT and other fetal anthropometric and maternal parameters. Results: PT was significantly lower in pregnancy-induced hypertensives than in the controls (28.95 ± 5.71 mm vs. 32.31 ± 5.47 mm, P = 0.000). There was a significant negative correlation between the PT and the degree of proteinuria (P = 0.011). Conversely, a significant positive correlation existed between PT and estimated gestational age (P = 0.000) and also estimated fetal weight (EFW) (P = 0.000), in both groups. This same relationship was observed between the body mass index and PT (P = 0.007) as well as the EFW (P = 0.002) in the control group. The mean EFW in pregnancy-induced hypertensives (2.23 ± 1.07 kg) was higher than in the controls (2.13 ± 1.03 kg), but the difference was not significant (P = 0.505). Conclusion: There was a reduction in the PT in PIH, which may be due to the appearance of proteinuria when the blood pressure was elevated. However, we did not observe the expected reduction in the EFW due to a reduction in PT, which usually results from proteinuria.
