Correlation of Placental Thickness with Gestational Age in Normal Singleton pregnancies using Transabdominal Ultrasound

Abstract

Objectives: To determine correlation of gestational age with placental thickness in normal singleton pregnancies using transabdominal ultrasound.

Study Design: Cross-sectional study.

Place and Duration of Study: 20th September 2021 to 19th March 2022.

Methodology: Total 150 patients who presented to our radiology department for obstetric ultrasound with accurate LMP, viable singleton pregnancy confirmed on ultrasound were selected. Placental thickness and gestational age recorded ultrasonographically after taking detailed history from antenatal women. The procedure was carried out with 3.5 MHz convex array curvilinear transducer through trans abdominal grey scale ultrasound technique. The procedure was performed on Apllio 300, 500 and LogiQ S8 ultrasound machines by principal investigator in ultrasound rooms.

Results:

Mean placental thickness was 29.64 ± 4.51 mm and mean gestational age was 30.56 ± 4.67 weeks. Correlation of gestational age with placental thickness in normal singleton pregnancies using transabdominal ultrasound is 0.932 with p-value of 0.0001.

Conclusion:

 This study concluded that there is a strong correlation of gestational age with placental thickness in normal singleton pregnancies using transabdominal ultrasound.

Keywords: gestational age, placental thickness, correlation.
