Signs And Symptoms Of Subchorionic Hematoma

Many women are scared to know that they have a Subchorionic hematoma (SCH) which refers to a blood clot. SCH affects a small percentage, over 1% of the pregnant women. The main symptom of SCH is spotting or bleeding during pregnancy, in its first trimester.

This result from the collection or pooling of blood in the area located between Chorion and the wall of the uterus. Chorion is the membrane that covers and surrounds the embryo.

Cause Of SCH

There is no definite cause of SCH. Research has shown that the bleeding in SCH is due to the separation of the egg from the uterus during egg implantation. The blood clot present in the uterus can cause miscarriage through its release in the uterus.



The ultrasound scan shows a black mass in the uterus, which is a sign of SCH. The ultrasound scan shows a hypoechoic crescent near the gestational sac. This crescent is an indication of SCH. Sometimes, detecting SCH can be difficult.


Signs And Symptoms

Most of the women affected by SCH are asymptomatic. The routine ultrasound scan detects the occurrence of SCH in such women. Women having SCH complain of light to heavy spotting or bleeding in the vagina due to the blood clot in the phase of early pregnancy. The bleeding is due to bleeding out of the clot.

Some women do not feel any pain with the bleeding while some may feel abdominal pain and cramps. Presence of blood irritates the uterus and this result in cramping. There may be abruption of placenta as well as premature labor. The patient may have threatened abortion.

Abdominal Pain

Some women have a healthy pregnancy despite the signs of bleeding. Hematoma that is of small size usually does not influence the pregnancy. A small hematoma will not cause bleeding and will cure on its own. However, if the hematoma is large or occurs during the early or the starting phase of the first trimester, there is a high risk of miscarriage.

Large hematomas also lead to many complications of pregnancy like restriction of the growth. Therefore, women should not ignore the signs of bleeding and should consult a doctor immediately who may prescribe an ultrasound test, which confirms the SCH and the size and location of the clot.

Treatment Of SCH

There are no methods to prevent SCH, which affects women of all age groups and races. There are no formal methods of treatment of SCH. Sometimes, the doctor’s advice to continue the daily activities while in some cases, the doctor may advice to relax and take it easy. Women should not strain themselves and must avoid exercise and heavy lifting.

The patient must take bed rest and avoid sexual activity during pregnancy until the blood clot dissolves and vanishes. The patient must drink plenty of fluids as dehydration may result in the damage to the baby as well as the clot.

In some cases, the doctor may advise the use of blood thinners like aspirin for bleeding out the clot. The patient can take hormones like estrogen as well as progesterone for pregnancy development.
