Subchorionic Hematoma

Subchorionic Hematoma, also known as subchorionic hemorrhage, refers to the collection of blood that accumulates between the placenta and the uterine wall during pregnancy. This condition can occur due to several factors and may lead to various symptoms that can be alarming for pregnant women. Understanding the causes, symptoms, and treatment options for Subchorionic Hematoma is essential to ensure a healthy pregnancy and minimize potential risks.

Causes of Subchorionic Hematoma

Subchorionic Hematoma can have multiple causes, including:

  1. Implantation: During the early stages of pregnancy, the embryo implants itself into the uterine lining. Sometimes, this process can cause blood vessels to rupture, resulting in a Subchorionic Hematoma.
  2. Placental detachment: If the placenta detaches partially or completely from the uterine wall, it can lead to bleeding and the formation of a Subchorionic Hematoma.
  3. Abnormal blood clotting: Certain conditions that affect blood clotting, such as clotting disorders or the use of blood-thinning medications, can increase the risk of developing a Subchorionic Hematoma.
  4. Trauma or injury: Physical trauma or injury to the abdominal area during pregnancy can cause blood vessels to rupture, resulting in a Subchorionic Hematoma.

Symptoms of Subchorionic Hematoma

Recognizing the symptoms associated with Subchorionic Hematoma is crucial for early detection and appropriate medical intervention. While some women may not experience any noticeable symptoms, others may exhibit the following:

  1. Vaginal bleeding: The most common symptom of Subchorionic Hematoma is vaginal bleeding, which can vary in intensity. It is essential to consult a healthcare professional if you experience any bleeding during pregnancy.
  2. Abdominal pain: Some women may experience mild to moderate abdominal pain or cramping, often accompanied by vaginal bleeding.
  3. Back pain: Back pain, particularly in the lower back, can be another indicator of Subchorionic Hematoma.
  4. Passing blood clots: In certain cases, the presence of blood clots in the vaginal discharge may indicate the presence of a Subchorionic Hematoma.
  5. No symptoms: It is important to note that some women may not experience any symptoms of Subchorionic Hematoma. Routine ultrasound scans during pregnancy can help detect the condition in such cases.

Diagnosing Subchorionic Hematoma

If you suspect the presence of a Subchorionic Hematoma, it is crucial to consult with your healthcare provider for a proper diagnosis. Diagnosing Subchorionic Hematoma typically involves the following:

  1. Medical history and physical examination: Your healthcare provider will inquire about your medical history, including any symptoms you may be experiencing, and perform a physical examination.
  2. Ultrasound: An ultrasound scan is commonly used to diagnose Subchorionic Hematoma. It allows the healthcare provider to visualize the placenta and the presence of any blood accumulation between the placenta and the uterine wall.

Treatment Options for Subchorionic Hematoma

The management of Subchorionic Hematoma depends on several factors, including the size of the hematoma, the severity of symptoms, and the stage of pregnancy. While there is no specific treatment to dissolve the hematoma, the following approaches may be considered:

  1. Bed rest: In cases where the hematoma is small and the bleeding is minimal, your healthcare provider may recommend bed rest for a certain period. This can help reduce activity and minimize the risk of further complications.
  2. Avoidance of strenuous activities: Engaging in strenuous activities, heavy lifting, or sexual intercourse may exacerbate the bleeding and increase the risk of complications. Your healthcare provider may advise you to avoid these activities until the hematoma resolves.
  3. Monitoring: Regular ultrasound scans may be recommended to monitor the size and progression of the hematoma. This can help ensure that the condition is not worsening and that the baby is developing normally.
  4. Medication: In some cases, your healthcare provider may prescribe medications, such as progesterone or estrogen, to support the pregnancy and reduce the risk of miscarriage.
  5. Surgical intervention: In rare cases where the hematoma is large, causing severe symptoms or complications, surgical intervention may be necessary. This may involve drainage of the hematoma or other procedures to address the underlying cause.

FAQs about Subchorionic Hematoma

  1. Can Subchorionic Hematoma Lead to Miscarriage?
    • While Subchorionic Hematoma can increase the risk of miscarriage, not all cases result in pregnancy loss. With proper medical care and monitoring, many women go on to have successful pregnancies.
  2. Is bed rest always required for Subchorionic Hematoma?
    • Bed rest is not always required for Subchorionic Hematoma. The need for bed rest depends on the size of the hematoma, the severity of symptoms, and the advice of your healthcare provider.
  3. Can Subchorionic Hematoma be prevented?
    • It is not always possible to prevent Subchorionic Hematoma, as its occurrence is often unpredictable. However, maintaining a healthy lifestyle, avoiding physical trauma, and following your healthcare provider’s recommendations can minimize the risk.
  4. Is Subchorionic Hematoma the same as a blood clot?
    • While a Subchorionic Hematoma involves the accumulation of blood, it is different from a blood clot that forms within a blood vessel. A Subchorionic Hematoma occurs between the placenta and the uterine wall.
  5. Can Subchorionic Hematoma cause complications for the baby?
    • In some cases, a large Subchorionic Hematoma may lead to complications, such as placental abruption or growth restrictions. Regular monitoring and appropriate medical intervention can help mitigate potential risks.


Subchorionic Hematoma can be a cause of concern for pregnant women, but with the right knowledge and medical care, the risks associated with this condition can be minimized. If you suspect the presence of a Subchorionic Hematoma or experience any symptoms such as vaginal bleeding or abdominal pain, it is crucial to consult with your healthcare provider promptly.
