Background

Placental anatomy.
  • Bleeding underneath the chorion membranes enclosing the fetus in the uterus
  • Most common cause of vaginal bleeding in patients who are 10-20 weeks by gestational age, make up ~11% of cases[1]

Clinical Features

  • Vaginal bleeding
  • Increased risk of pregnancy loss, particularly when amounting to 25% or more of the gestational sac[2]

Differential Diagnosis

Vaginal Bleeding in Pregnancy (<20wks)

Vaginal Bleeding in Pregnancy (>20wks)

Evaluation

An 8-week fetus associated with a small (less than one-third of the chorionic sac circumference) subchorionic hematoma (arrows).

Workup

  • Pregnancy test
  • CBC
  • Type & screen
