subchorionic hematoma/bleed


Explanation:
A possible interpretation given the context.

A subchorionic bleed (also known as a subchorionic hematoma) is the accumulation of blood between the uterine lining and the chorion (the outer fetal membrane, next to the uterus) or under the placenta itself. It can cause light to heavy spotting or bleeding, but it may not. Most subchorionic bleeds resolve on their own, and women go on to have perfectly healthy pregnancies. But because bleeds or clots can rarely cause problems, all subchorionic bleeds are monitored.

Chorionic hematoma is the pooling of blood (hematoma) between the chorion, a membrane surrounding the embryo, and the uterine wall.[2] It occurs in about 3.1% of all pregnancies,[2] it is the most common sonographic abnormality and the most common cause of first trimester bleeding.

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.[5] Symptoms include vaginal bleeding, abdominal pain, premature labor and threatened abortion.[6]

Ultrasonography is the preferred method of diagnosis.[7] A chorionic hematoma appears on ultrasound as a hypoechoic crescent adjacent to the gestational sac. The hematoma is considered small if it is under 20% of the size of the sac and large if it is over 50%.[2]
