What does Subchorionic hematoma bleeding look like? A subchorionic hemorrhage may cause bleeding that is visible or you may only see it during an ultrasound done in pregnancy for a different reason. It can be varying in quantity from spotting to heavy bleeding.
How does a subchorionic hemorrhage resolve?
Your treatment may include:
- A RhoGAM, if you are Rh-negative and your baby is Rh-positive
- Sonograms about once a month to check your baby's growth, possibly more frequently
- Preterm labor treatment if you start having contractions
- Hospitalization, especially if bleeding occurs after 24 weeks
What size subchorionic hematoma is considered large?

What is the term for blood that collects between the uterine wall and the chorionic membrane during pregnancy?
Subchorionic hemorrhage. Subchorionic hemorrhage occurs when there is perigestational hemorrhage and blood collects between the uterine wall and the chorionic membrane in pregnancy. It is a frequent cause of first and second trimester bleeding.
How far along can you get a subchorionic hematoma?
The treatment for a subchorionic hematoma will depend on several factors. These include how far along you are in your pregnancy and the size of your hematoma. Before 20 weeks' gestation.

Epidemiology
Radiographic Features
- crescentic collection with elevation of the chorionic membrane
- depending on the time elapsed since bleeding, the collection will have variable echotexture
- in almost all cases there is an extension of the hematoma towards the margin of the placenta 3
Treatment and Prognosis
- Fetal outcome is dependent on the size of the hematoma, maternal age, and gestational age 2. In most cases, the hematoma gradually decreases in size on follow-up and can resolve over 1-2 weeks 9. A subchorionic hemorrhage places the gestation at increased risk of: 1. placental abruption 4,6 2. preterm labor 6 If the collection extends up to the int...
Differential Diagnosis
- General imaging differential considerations include: 1. retroplacental hemorrhage 2. marginal subchorionic hematoma can mimic a twin gestational sac(particularly failed early twin gestational sac) 3. chorioamniotic separation
