Assessing Placental Thickness Using Ultrasonic Technology To Predict Placenta Accreta Invasion

Objectives: The purpose of the work had been to assess the correlation of ultrasonic assessed placental thickness and degree of invasion in cases of abnormal invasion of low-lying placenta.Patients and Methods: This prospective cohort observational work had been conducted on 50 pregnant women with gestational age between 20 - 40 weeks and maternal age of 20–30 years. Low-lying placenta, history of one or more cesarean births, and body mass index (BMI) of less than 30 were the inclusion criteria. Participants were categorized into two groups: the first group had been low lying placenta (n= 18), and second group was placenta previa (n= 32).Results: There was a highly positive statistically significant correlation between lower uterine segment thicknesses and maximum placental thickness, abnormal placenta (previa or accreta) by the US, Blood loss, blood transfusion, caesarian hysterectomy, abnormal placenta (previa or accreta) throughout surgery and myometrial fibres located in the placenta' basal plate (p<0.001). a statistically significant positive association had been existed among maximum placental thickness and lower uterine segment thickness, abnormal placenta (previa or accreta) by US, Blood loss, blood transfusion, caesarian hysterectomy, atypical placenta (previa or accreta) during Surgery and Myometrial fibers in basal plate of placenta (p<0.05).Conclusions: A significant correlation existed between ultrasonic assessed placental thickness and degree of abnormal invasion of low-lying placenta.
