Assessment of the Placenta Location in Pregnant Women with Previous Cesarean Section

Abstract

This was a descriptive cross-sectional study conducted at the department of obstetrics and gynecology in Bahry Educational Hospital and Maternal Specialist Hospital and Elshaikh Ali Fadoul Hospital; it was conduct during the period from April to august 2017. The main aim was to assess the association of placenta location with previous caesarean section (CS) in pregnant women. In antenatal clinic as per protocol 56 pregnant women were scanned in their second and third trimester for fetal wellbeing and placental localization after taking a detailed obstetrical history and clinical examination. All women without previous caesarean section were excluded. Methodology the data collection from pt by data collection sheet and analyzed by SPSS. The result of the study revealed that the fundal placenta was reported in 8.9%, posterior placenta was 21.4%, anterior placenta was 57.1%, placenta previa was 7.1% and low lying placenta was 5.4%. There was a significant difference in placental location when there is a CS scar present on the uterus. Women with a previous history of CS are significantly less likely to have a fundal placenta and more likely to have the placenta located on the anterior and posterior wall of the uterus in a subsequent pregnancy. Me was found no statistically significant difference in the incidence of low-lying placentae between the groups. Previous CS may have a significant impact on placental location in subsequent pregnancies. The mechanism behind this effect is not clear; however this observation may provide indirect evidence that the presence of a CS scar in the uterus has a more ‘global’ effect on the endometrium than the physical presence of a scar in isolation.
