Podcast 740: Placenta Previa

Contributor: Peter Bakes, MD

Educational Pearls:

  • High concern causes of third trimester vaginal bleeding include placenta previa, placental abruption, or vasa previa
  • In placenta previa, the placenta implants over the cervix and this condition
    • Often noted during routine prenatal care on transabdominal ultrasound
  • Patients present with painful vaginal bleeding, usually in the absence of trauma
  • Avoid pelvic exam, transvaginal ultrasound, or digital vaginal exam in placenta previa
  • Risk factors for placenta previa include multiple gestations, previous medical abortions, advanced maternal age, and previous placenta previa
  • Management usually includes admission to the hospital
    • >37 weeks: admission for c-section
    • 34-37 weeks: judgment call based on maternal/fetal stability
    • <34 weeks: steroids for fetal lung maturation and delay delivery
