Ultrasound showing a subchorionic hemorrhage[1] |
Chorionic hematoma is the pooling of blood (
Cause and diagnosis
Chorionic hematomas can be caused by the separation of the chorion from the endometrium (inner membrane of the uterus). Hematomas are classified by their location between tissue layers:[4]
- Subchorionic hematomas, the most common type, are between the chorion and endometrium.
- Retroplacental hematomas are entirely behind the placenta and not touching the gestational sac.
- Subamniotic or preplacental hematomas are contained within amnion and chorion. Rare.
Most patients with a small subchorionic hematoma are asymptomatic.
Prognosis and treatment
The presence of subchorionic bleeding around the gestational sac does not have a significant association with miscarriage overall.
