Apruption ?'s: A subchorionic hemorrhage (SCH) occurs when a portion of the placenta separates from its attachment to the uterus. Insertion of the placenta near the cervical canal presents more likelihood of a SCH secondary to trauma (increased physical activity, etc). Placental attachment is very redundant, however, and adverse effects are modified with few ending in miscarriage, etc..
