Chorionic hematoma (otherwise referred to as chorionic hemorrhage) is the pooling of blood between the chorion, a membrane encompassing the uterine wall and the embryo.
With a frequency of about 3 percent in all pregnancies, it is the most frequent sonographic anomaly and the most frequent cause of first trimester bleeding.
Subchorionic hematoma, on the other hand, is a classification of chorionic hematoma that specifically refers to blood accumulation within the chorion folds or between the placenta and uterus.
Below are some 10 facts about subchorionic hematoma (and chorionic hematoma):
1. Chorion membrane
Subchorionic hematoma involves accumulation of blood between membranes of the placenta and the uterus. A more specialized name of the membrane is chorion. A few medical professionals will likewise simply allude to it as a bloodstream clot.
2. Causative factors
There isn’t any known cause of a subchorionic hematoma (SCH) but numerous scientists hypothesize that either egg isolation or tears in the uterus causes it to bleed.
There may be nothing the woman could have done to trigger the condition, subchorionic hematoma strikes pregnant ladies of any age and background. Chorionic hematomas is due to the partition of the chorion from the endometrium.
3. Chorionic hematomas are classified by the area affected between tissue layers:
o Retroplacental hematomas – behind the placenta and never touches the gestational sac.
o Subamniotic or preplacental hematomas – contained inside of amnion and chorion.
o Subchorionic hematomas – the most frequent, located between the endometrium and chorion.
4. Signs and symptoms
Most patients that have subchorionic hematoma are asymptomatic. If symptoms are present, it may include severe stomach pains, vaginal bleeding, threatened abortion, miscarriage, et al.
5. Diagnostic procedure
Ultrasonography is the favored approach in determining the hematoma. A chorionic hematoma turns up on ultrasound like a hypoechoic crescent next to the gestational sac.
The hematoma is regarded as small if it is less than 20 percent in comparison to the actual sac and large if it is more than 50 percent.
6. Subchorionic hematoma and miscarriage
Subchorionic bleeding around the gestational sac generally doesn’t have a significant relation to miscarriage.
Conversely, the presence of intrauterine hematoma noticed before nine weeks of gestation has been relevant to an expanded danger of miscarriage.
Several years ago, when pregnant women suffer from early trimester hemorrhage, doctors immediately expected that it was a looming miscarriage. They simply do not have any other data to take due to lack of technology.
At present, with the assistance of ultrasound and innovation, doctors now have the capacity to come up with a more sophisticated analysis.
Diagnosis of subchorionic hematoma is usually dependent on manifested symptoms and representations through ultrasound results. For example, in patients who visit their doctor with complaints of vaginal bleeding before scheduled pregnancy, further examination will be necessary.
Ultrasound, either transvaginal or abdominal, would most probably be performed. Amidst the ultrasound procedure, the doctor or radiologist will also assess the baby to evaluate its condition.
Identifying a new subchorionic hematoma with an untrained eye is difficult. The hematoma commonly turns up as a dark mass inside the uterus. To consider, conventional ultrasound photos seem blackish, it will certainly be a challenge.
When a visual of the blood clot is established, and turns out that the woman isn’t having a miscarriage, a diagnosis of subchorionic hematoma is made.
There aren’t any definite treatment method for this type of blood accumulation. Each doctor may take a different approach compared to the other.
There will be doctors that allow continuation of everyday activities while some recommend complete bed rest.
10. Better than miscarriage
Being diagnosed with subchorionic hematoma compared to miscarriage is most likely a better news. But having subchorionic hematoma certainly has its own set of concerns.
