What this Trial Is About
Researchers are evaluating how certain ultrasound measurements—such as cervical length, placental thickness, and the distance from the placental edge to the cervix—can predict the risk of bleeding before birth and emergency cesarean delivery in women with placenta previa who do not show symptoms. Placenta previa occurs in about 3 to 5 pregnancies per 1000 worldwide and is becoming more common due to factors like maternal age and cesarean rates. Understanding these ultrasound findings can help improve care and outcomes for these women. The study observes pregnant women diagnosed with placenta previa between 28 and 37 weeks of gestation. Ultrasound parameters are used to assess their condition, focusing on cervical length, placental thickness, and placental edge location relative to the cervix. The goal is to identify those at high risk for complications such as antepartum hemorrhage, preterm cesarean section, or the need for hysterectomy, to guide early hospital admission and delivery planning. Participants undergo ultrasound assessments and are monitored until delivery for outcomes including maternal bleeding rates, need for blood transfusions, emergency cesarean delivery, premature birth, cesarean hysterectomy, and postpartum hemorrhage within two hours of delivery. The study tracks these measures to better understand risks and improve management strategies for asymptomatic women with placenta previa. The total participation duration varies with pregnancy timing and delivery.
