Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Placenta accreta is a substantially life threatening condition and one of the causes of maternal morbidity and mortality in the world. According to study done in United Kingdom, The estimated incidence of placenta accreta/increta/percreta was 1.7 per 10,000 maternities overall and 577 per 10,000 in women with both a previous cesarean delivery and placenta previa. in a tertiary south Italian center, The incidence increased from 0.12% during the 1970s, to 0.31% during the 2000s.While in United States of America, the prevalence of placenta accreta was 3.7 per 1000 deliveries.

placenta accreta

Having at least one sign suggestive of placenta accreta

two-dimensional ultrasound and color Doppler

Intervention Type DEVICE

the eligible participants will be searched for signs suggestive of placenta accreta; low implantation of the gestational sac (\<4cm from the external os), presence of placental lakes, Disruption of placental-myometrial interface and trophoblast overlapping a uterine scar by 2 dimensional transvaginal ultrasound and Intraplacental dilated vessels, turbulent blood flows and greatly increased periplacental vascularity by Doppler ultrasound by level II sonographer and co-investigator under his supervision using ultrasound device.

normal placenta

Never having any of the signs suggestive of placenta accreta
