Subchorionic Hematoma In Early Pregnancy: Symptoms And Treatment

About 20 % pregnant women tend to experience slight bleeding during early pregnancy, though it is often difficult to tell what is triggering it. Subchorionic hematomas are rather hard to detect since they don’t always cause noticeable bleeding, especially when they are very small. There is no known cause for this problem and treatment options are less as well.

Subchorionic hematomas form in the layers of the placenta. These clots can cause the placenta to rupture or detach from the wall of the uterus if they become too big or if they cannot be eventually re-absorbed.

There aren’t any risk factors linked to the development of subchorionic hematomas, and the exact etiology is not known.

A large section of women who bleed during the first 3 months of pregnancy go on to have perfectly normal pregnancies and childbirths. However, since subchorionic hematomas have been associated with a raised risk of abruptio placenta and pre-term labor, never disregard bleeding / spotting.

There is no known cause for a Subchorionic Hematoma, but experts hypothesize that during implantation, the egg separates slightly or tears from the uterus resulting in a bleed / clot. There is nothing you could have done to prevent or trigger a Subchorionic Hematoma.

Diagnosing a Subchorionic Hematoma depends on the symptoms and visualization on the sonogram. The common complaint is bleeding during early pregnancy. An ultrasound is conducted to understand what is causing the bleeding. Your doctor will locate the fetus and evaluate its condition. The blood clot is seen as a black mass in the uterus. It appears as if another placenta is present.

Subchorionic Hematoma In Early Pregnancy Symptoms

  • Bleeding or spotting is the commonly seen manifestation, usually, in the 1st trimester.
  • Occasionally, a subchorionic hematoma is perceived during a routine ultrasound, and there may not be any symptom.
  • The bleeding may be light or heavy, depending on the size of the SCH. Bleeding also indicates miscarriage, and thus, you must call your doctor if you detect any vaginal bleeding during the course of your pregnancy.
  • Small hematomas tend to eventually dissolve on their own.
  • At times, it is possible for the clot to get in-between the uterine wall and the placenta and cause a miscarriage. Women having subchorionic hematomas are at a huge risk for developing placental abruption; this is a condition wherein the placenta tears away from the uterus. It is a serious pregnancy complication and calls for immediate medical attention; the health of the fetus is in grave danger.

Treatment For Subchorionic Hematoma

  • There is no specific treatment plan to manage subchorionic hematomas. Surgical intervention is not an option at all. Some doctors prefer the ‘wait and watch’ approach, whilst others opt for drugs and medicines.
  • Your gynecologist will ask you to take things slow and get ample rest. Bed rest may be necessary in extreme cases.
  • You will be advised to abstain from sexual activity until the clot dissolves or bleeds out.
  • The doctor may prescribe blood thinners to essentially make the clot ‘bleed out’.
  • Estrogen and progesterone hormones may be prescribed to help in the early development of pregnancy.
  • Lifting heavy weights and straining must be avoided.
