Seeing "subchorionic hemorrhage" on your ultrasound report can be alarming. This article explains what SCH is, its causes, symptoms, treatment, and what you can expect during your pregnancy. We'll cover this common pregnancy complication in detail, providing reassurance and information to help you navigate this experience.

What is a Subchorionic Hemorrhage (SCH)?

A subchorionic hemorrhage (SCH) is bleeding that occurs between the uterine wall and the chorion, the outermost membrane surrounding the developing fetus. This bleeding is typically seen on an ultrasound as a collection of blood. It's important to remember that many SCHs resolve on their own without causing any complications.

Causes of Subchorionic Hemorrhage

The exact cause of an SCH isn't always clear. However, several factors are associated with its development:

Implantation bleeding: The fertilized egg's implantation into the uterine wall can sometimes cause minor bleeding.
Trauma: Physical trauma to the abdomen, even minor, can contribute to SCH.
Underlying conditions: Conditions like hypertension (high blood pressure) or clotting disorders can increase the risk.
Cervical insufficiency: A weakened cervix might contribute to bleeding.
Advanced maternal age: Older pregnant individuals might have a slightly elevated risk.

Symptoms of Subchorionic Hemorrhage

Many women with SCH experience no symptoms at all. The hemorrhage is often discovered incidentally during a routine ultrasound. However, some women might experience:

Vaginal bleeding (ranging from light spotting to heavier bleeding)
Abdominal cramping or pain

Diagnosis of Subchorionic Hemorrhage

SCH is primarily diagnosed through a transvaginal ultrasound. This type of ultrasound provides a clearer image of the uterus and the developing pregnancy. The ultrasound will show a collection of blood outside the gestational sac, between the gestational sac and the uterine wall.

Treatment for Subchorionic Hemorrhage

Treatment for SCH often involves watchful waiting. Most SCHs resolve spontaneously without any intervention. Your doctor will likely monitor the size and location of the hemorrhage at follow-up ultrasounds. Bed rest is often recommended, but the evidence supporting its effectiveness is limited. Specific recommendations will depend on the size of the hemorrhage, the presence of symptoms, and other factors.

Complications Associated with Subchorionic Hemorrhage

While most SCHs are harmless, some potential complications exist. These include:

Miscarriage: In some cases, a large SCH can increase the risk of miscarriage, although this is not always the case.
Preterm labor: In rare instances, SCH can be associated with preterm labor.
Placental abruption: A severe and rare complication where the placenta separates from the uterine wall.

Frequently Asked Questions (FAQs)

Does an SCH always mean a miscarriage?

No, the vast majority of women with SCH go on to have healthy pregnancies. The risk of miscarriage is increased slightly, but many pregnancies with SCH progress normally.

How long does it take for an SCH to resolve?

The time it takes for an SCH to resolve varies. Some resolve within a few weeks, while others might take longer. Your doctor will monitor your progress through regular ultrasounds.

What can I expect during my pregnancy with an SCH?

Regular monitoring with ultrasounds is crucial. Your healthcare provider will assess the size and location of the hemorrhage. You'll likely need to avoid strenuous activity and report any concerning symptoms immediately. Open communication with your doctor is key throughout your pregnancy.

Conclusion

A subchorionic hemorrhage (SCH) can be a concerning diagnosis, but it's important to remember that many resolve without complications. Regular monitoring by your healthcare provider is crucial, and open communication will ease your concerns and ensure a safe pregnancy. If you have any concerns or questions, don't hesitate to contact your doctor or midwife.
