Placenta Previa Clinical Trial
Official title:
Sonographic Parameters and Risk of Antepartum Hemorrhage in Asymptomatic Women With Placenta Previa: A Cohort Study
The aim of this study is to evaluate the effectiveness of ultrasonographic parameters (cervical length, placental thickness and distance placental edge from internal os of the cervix) in predicting the risk of antepartum hemorrhage and emergency cesarean delivery in asymptomatic women with placenta previa.
The incidence of placenta previa is 3-5 per 1000 pregnancies worldwide and is still rising because of increased maternal age, parity, cesarean section rates, assisted reproductive technology, maternal smoking with the widespread use of transvaginal ultrasound. antepartum hemorrhage is an important cause of maternal and neonatal morbidity and mortality in pregnant women with placenta previa. However, the epidemiological characteristics are not completely understood. this study aims at evaluating the sonographic findings in asymptomatic women with placenta previa as cervical length, placenta thickness and distance from cervix to placental edge to recommend management for in-patients versus out-patient antenatal care and early planned hospital admission and delivery for women at high risk of antepartum hemorrhage and preterm cesarean section and hysterectomy for life threatening antepartum hemorrhage. ;
