Sonographic Parameters and Risk of Antepartum Hemorrhage in Asymptomatic Women With Placenta Previa: A Cohort Study

Sponsor

Ain Shams University

Enrollment

68 participants

Start Date

Jun 1, 2022

Study Type

OBSERVATIONAL

Conditions

Placenta Previa

Summary

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.

Eligibility

Sex: FEMALE

Inclusion Criteria2

  • Asymptomatic women diagnosed with placenta previa according to RCOG (GTG No. 27a, 2018): placenta lies directly over the internal os for pregnancies more than 16 weeks' gestation on transabdominal or transvaginal scanning.
  • Gestational age between 28 till 37 weeks' gestation (as delivery should be considered between 36 and 37 weeks of gestation for women presenting with uncomplicated placenta previa)

Exclusion Criteria9

  • Multiple pregnancies.
  • Threatened preterm labor or preterm rupture of membranes.
  • History of bleeding in the current pregnancy.
  • Polyhydraminos (AFI > 25 cm).
  • History of cervical surgery (cone biopsy).
  • Presence of cervical cerclage.
  • Maternal use of vaginla progesterone.
  • History of maternal disease (hypertensive, DM, Cardiac).
  • Fetal malformation or growth restriction
