Subchorionic Hemorrhage in 2nd Trimester (Early Pregnancy)


This condition can also be referred to as subchorionic hematoma. There's immoderate bleeding, blood clots or hematoma that originates between the chorionic membranes surrounding the embryo, and the wall of the uterus. Subchorionic hemorrhage is precipitated due to the fact the membrane surrounding the embryo separates from the inside lining of the uterus. This is one of the common cause of bleeding during second trimester.


There are a quantity of reasons that play important role and have a great influence on such event e.g  patient age, hematoma size and overall health of fetus. Older pregnant women with enormous amounts of bleeding have more chances of  miscarriage. Females who expertise subchorionic hemorrhage in late second trimester also have an increased risk of miscarriage. Subchorionic hemorrhage also expand the chance for stillbirth, separation of the placenta from the uterus after 20 weeks of being pregnant and contractions inducing the cervix earlier than 37 weeks of being pregnant often called preterm labor.

A subchorionic hematoma is classified as small if it is lower than 20 percent of the dimensions of the gestational sac, which is the anatomical structure that holds the embryo and the amniotic fluid. It is labeled as medium sized if it ranges between 20 to 50 percent of the dimensions of the gestational sac, and considered gigantic if it is more than 50 percent of the scale of the gestational sac.


A hematoma that is small in size normally subsides within 1 to 2 weeks. Nevertheless, a gigantic hematoma that is 50 percent of the sac surrounding the embryo to rupture the walls of the uterus could continue to get higher, inflicting the gestational sac to end up compressed and membranes to burst, to be able to finally abort the pregnancy.


Ultrasound is the most frequently used approach for deciding the presence of a subchorionic hemorrhage in view that it may be quite simply carried out at the patient’s bedside and because there is not any danger from radiation as with an MRI or CT scan. However, ultrasound uncovers about 20 percent of all subchorionic hemorrhages, certainly if the blood doesn’t acquire in the space between the chorionic membrane and the wall of the uterus. An ultrasound is most potent to find a subchorionic hemorrhage whether it is performed immediately after there has been an episode of vaginal bleeding. Using a color doppler also raises the capability to find a subchorionic hemorrhage.
