ABSTRACT

Objective: The purpose of the current study was to evaluate the mean placental thickness in centimeters in the second and third trimester. It was also aimed to assess the effects of placental location, gestational age, gravidity and parity on the thickness of placenta with the hypothesis that these would have a significant impact on placental thickness.
Study Design: A cross sectional observational study
Place and Duration: It was conducted for a period of 2 months at Radiology department of Maternal and Child Health Centre, (MCHC) PIMS.
Methodology: A total of 185 patients were enrolled for the study. A standardized method for measuring placental thickness was developed in which it was measured perpendicular to the uterine wall and at the level of umbilical cord insertion.
Results: A total of 167 patients were included in the study who presented for routine antenatal scanning. Mean placental thickness was calculated to be 2.86+1.80 cms in our local population. 47% of placenta were located anteriorly. Various predetermined variables were noted to have a significant impact on placental thickness.
Conclusion: Placental thickness is surely effected by the gestational age, parity and gravidity of the patient, as well as by the location of the placenta.
Keywords: Gestational age, parity, placenta, placental location.
