What is a Subchorionic Hemorrhage?

Subchorionic Hemorrhage is bleeding behind the placenta, often caused by a clot.  In most cases, this clot will dissolve away, resolving the problem and allowing the pregnancy to progress normally.  It may take several weeks for this clot to dissolve.  Treatment for a Subchorionic hemorrhage is typically bed rest.

Rarely, the clot dissects between the placenta and the attachment to mother.  This may lead to placental abruption.  Risk factors that may increase the chance of experiencing this include high blood pressure, smoking and cocaine use.  Symptoms may include:

–  contractions that don’t stop 

–  pain in the uterus 

–  tenderness in the abdomen over the uterus 

–  vaginal bleeding

If you experience these symptoms, you should contact your physician immediately.  Treatment of placental abruption will vary according to your particular state.  If the separation of the placenta is small, the baby isn’t in distress, and your condition is stable, you may be able to go home and continue the pregnancy with frequent checkups.  If the separation is moderate to severe but the baby is not in distress and your condition is stable, the doctor may induce labor and perform a vaginal delivery.  If the baby is in distress or if you are losing a lot of blood, the doctor will most likely deliver the baby immediately by cesarean section.

    I think it’s important for those suffering with this frightening condition that you report the correct information. A Subchorionic Hemorrhage (active bleeding)/Hematoma (clot) is actually bleeding that occurs within the uterus between the Chorion and the Uterine wall (not behind the placenta). A chorionic hematoma that is positioned between the placenta and uterine wall, as per your description, is known as a Retroplacental Hematoma. Subchorionic Hematomas are the most common form of chorionic hemorrhage complications. I am not a medical professional, so cannot back up my statements with Empirical evidence, however as one suffering from this condition, have done a lot of research.
