What are the risks associated with a subchorionic hematoma?

Problems: Subchorionic bleeding is usually placental in origin, making a stable bleed a stable placental abruption. Subchorionic bleeding is associated with elevated rates of miscarriage, preterm labor, placental abruption, and preterm rupture of membranes. Many cases will turn out ok though. An OB should be involved, and serial ultrasound can be helpful in following the bleed.

If the placenta: Separates too much from the uterine wall, or if the blood supply to the baby is otherwise compromised, there is the possibility of fetal death & pregnancy loss. It depends on where the hematoma is located, how large, is it enlarging, fetal age. Please check w your ob. However, many of these resolve without any problem, & your baby is fine. Hope this is the case for you!
