Early pregnancy subchorionic hematoma (SCH) is a common and usually benign condition that can occur during the first trimester of pregnancy. It is a collection of blood between the uterine wall and the chorion, the outermost layer of the placenta. While SCH is generally not a cause for concern, it is important to be aware of the symptoms, diagnosis, and management of SCH and its associated complications. This blog post will provide a comprehensive overview of early pregnancy subchorionic hematoma discharge, as well as a discussion of potential risks. We will review the causes, symptoms, and treatment options for this condition, as well as advice for care and monitoring during an SCH pregnancy. Understanding the different aspects of this condition can help individuals make informed decisions and get the best possible care for their pregnancy.
How can you care for yourself at home?
- Not cause any problems for you or the baby.
- Turn out to be something more serious. But if this happens, its best to find out early. Then, you and your physician can address any complications as soon as possible.
While the rate of premature birth and the type of delivery are unaffected if pregnant women can carry their pregnancy to term, subchorionic hematoma increases the risk of spontaneous abortion.  At more than 20 weeks of gestation, first-trimester subchorionic hematoma is not linked to poor pregnancy outcomes.  When nonspecific pelvic pain is present, the ratio of surrounding hematoma to gestational sac increases, lengthening the hospital stay and the likelihood of pregnancy loss .
Subchorionic hematoma (SCH) in pregnant women is linked to an increased risk of miscarriage early in the pregnancy.  Placental abruption is five times more likely to occur in women who have subchorionic hematoma than in healthy women. Patients with subchorionic hematoma are also at risk for other side effects, such as premature labor, early or late pregnancy loss, and premature membrane rupture. .
Specific patient complaints, gestational age, and the patient’s hemodynamic stability or instability should all be taken into consideration during treatment and management. Treatment should be started right away depending on the severity of the patient’s complaint, which is frequently vaginal bleeding in the context of a subchorionic hemorrhage.  Anti-D immune globulin should be administered to patients who present with vaginal bleeding and are RhD negative in order to prevent alloimmunization in subsequent pregnancies. Treatments should be individualized for each patient based on their symptoms, including their type and severity, as well as the size and location of the subchorionic hematoma . .
The fetal outcome for women with sonographically identified subchorionic hematomas depends on the size of the hematoma, the mother’s age, and the gestational age.  Subchorionic hematoma is associated with an increased risk of pregnancy loss if it accounts for 25% or more of the volume of the gestational sac When the hematoma is retroplacental as opposed to marginal, there is also a higher risk of a negative outcome.  The likelihood of a subsequent pregnancy failing increases the earlier in pregnancy a subchorionic hematoma is discovered. .

When a subchorionic bleed is suspected before 20 weeks’ gestation, we advise reducing activity, advising against any travel, and instructing mom to go to the hospital should vaginal bleeding, cramps, or contractions occur. As the pregnancy progresses, recommendations may include:
Women who have a large subchorionic clot or subchorionic hematoma diagnosed prior to 22 weeks’ gestation must take into account the possible outcomes of a decision to proceed with the pregnancy, such as what might happen if the baby is born early. They must accept the possibility that they will give birth to a child who is extremely premature and that the child may not develop normally on the neurological or physical levels. For example, at 24 weeks%E2%80%99 gestation, the overall survival rate in our Newborn ICU is over 50%, but there is a high rate of long-term neurologic or physical disabilities Furthermore, there is a chance that fetal growth issues will force an early delivery, which could have negative neurologic and/or physical effects.
The chorion and the amnion, which make up the “bag of waters” within the uterus, are what are known as subchorionic hematomas or subchorionic clots. The inner layer, closer to the baby, is the amnion. The chorion is the outer layer, which typically rests against the uterine wall. A blood clot between the uterus and the bag of waters is referred to as a “subchorionic clot” or “subchorionic hematoma.”
The arrows in the image on the left point to a subchorionic clot with a crescent shape. The at right shows a larger, rounded subchorionic clot. During the previous week, both women had bleeding episodes and passed blood clots. Rarely, we will be able to see where the bleeding is coming from underneath the membranes. Usually, we cannot.
How does a subchorionic hematoma look on ultrasound? We see subchorionic hematomas or suspect subchorionic clots in perhaps 1% of pregnancies in the between 13 and 22 weeks Most of these affect females who have experienced vaginal bleeding. These must be distinguished from areas of the uterine wall where the membranes have not fused, which are very common before 16 weeks of pregnancy. The material visible beneath the membranes has an irregular texture, and the amniotic fluid has a speckled appearance rather than a uniform one. These findings point to a bleed or hematoma rather than membrane separation.
