subchorionic hemorrhage
Pronunciation: sub-kor-ee-ON-ik HEM-or-ij
Bleeding between the chorion and uterine wall, visible on ultrasound as a fluid collection in early pregnancy.
Full Definition
Subchorionic hemorrhage, also known as subchorionic hematoma, represents bleeding that occurs between the chorionic membrane and the uterine wall during early pregnancy. This condition appears as an anechoic or hypoechoic collection on ultrasound imaging and is one of the most common causes of first-trimester bleeding. While many subchorionic hemorrhages resolve spontaneously, larger ones may increase the risk of pregnancy complications including miscarriage or preterm delivery.
Usage
Usage note: Can be abbreviated as SCH in clinical notes; distinguish from other types of pregnancy-related bleeding.
