An observational study in Placenta Previa, sponsored by Ain Shams University. Recruiting at 1 site in Egypt. Open to female participants. Per ClinicalTrials.gov, last updated 2024-07-30.
Sponsored by Ain Shams University · Observational
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.
80 studies on the registry are indexed under Placenta Previa; 17 are open to participants now.
This study's planned enrollment of 68 is below the median of 100 across 32 observational studies indexed under Placenta Previa.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
