What is a Subchorionic Hemorrhage?

What is a Subchorionic Hemorrhage?

SubChorionic bleeding is also known by the name of subchorionic hematoma and is the accretion of blood within the folds of the chorion which is the outer fetal membrane next to the placenta or between the uterus and the placenta itself. Bleeding may be small, moderate or large in amount. Most subchorionic bleeds resolve on its own and females go on to have fully healthful pregnancies. About 1 percent (1%) of all pregnancies has a subchorionic bleed. In most of the cases subchorionic hemorrhage occur in first trimester of pregnancy.

The designated motive and explanations of subchorionic hematoma causes remain to be clear. Some doctors think that on the time of first or second trimester, if the embryo detaches away from the uterus, it may cause bleeding in the uterus. Ladies of all ages can expertise this whilst pregnant. Reviews reveal that this will result in miscarriage. A hematoma in the uterus that is undersized won't have a thorough effect on the being pregnant or even on the little one. Complications that may arise from a huge hematoma in the uterus are a preterm labor or restriction in the fetal growth.

The one and most common symptom of that is bleeding. The variety and the harshness of the bleeding might be special from one woman to the other. Comparable to some women might see only gentle spotting, while others may experience a heavy drift of blood, perhaps with blood clots too. Alas, if women experience an excessive amount of vaginal bleeding because of hematoma, she could obtain a prognosis of a threatened miscarriage.

Even though this sounds very scary, a few ladies have had threatened miscarriages due to subchorionic hemorrhageh while others remain safe even after bleeding. Apart from bleeding, one of the vital sign of subchorionic hemorrhage is abdominal cramps within the specified area. In some circumstances, there may be no outward subchorionic hematoma symptoms experienced by a woman in any respect and the condition is only diagnosed if the medical professional conducts ultrasound to verify the total well being and progress of the child

Sadly, there is no exact or formal cure that's administered for ladies who have such hematoma within the uterus even as pregnant. Some medical professionals advise pregnant ladies who've hematoma, to continue their routine activities with no worries at all. Nevertheless, nearly all pregnant females, who have a hematoma in their uterus during pregnancy are requested to avoid carrying out any activity that requires strenuous body movements. Therefore, lifting weights, strolling too speedy or rigorous activity must not be performed by females who've hematoma whilst pregnant.

Apart from following the physician’s advice carefully, women who've been identified with subchorionic hematoma in the uterus must be careful regarding her diet plan, exercise plan, day to day activities because they are very important in the overall health of fetus and prevention of hemmorhage in next trimesters.
Subchorionic Hemorrhage in first Trimester

Subchorionic Hemorrhage in first Trimester (Early pregnancy)

Many years ago, when a woman suffered with early trimester bleeding, doctors assumed it used to be an impending miscarriage. They had no other expertise to head on. Now with the help of ultrasound technology, medical professionals are capable to make a more definitive prognosis. SCH or Subchorionic Hematoma is a gathering of blood between the membranes of the placenta and the uterus. Clinically it is named as Subchorionic Hemorrhag.

There’s no identified reason for a SCH but many researchers speculate that during the period of egg implantation, the egg relatively separates or tears up from the uterus causing a bleed. There may be nothing a woman can do to hinder or prevent them. SCH happens to pregnant females of all ages and races. Ladies with SCH are at higher risk for placental abruption. Normally, placental abruption occurs when the placenta tears away from the uterus. That is an extreme pregnancy complication that requires instantaneous medical intervention. If the placenta separates from the uterine wall, the well being of the fetus becomes risky.

Diagnosing a SCH is founded on its symptoms and visualization via ultrasound scan. Many females consult with the medical professional or emergency department with the chief complaint of vaginal bleeding in the course of early pregnancy. An ultrasound, both transvaginal and belly, would most probably be performed. During the ultrasound scan, the health care professional or radiologist will find the fetus and check its present condition. The clot appears as a black mass within the uterus. After a visual detection of the blood clot is made, radiologist try to calculate the dimension of hematoma to provide proper diagnosis and prognosis of subchorionic hemorrhage.


There is not any licensed medication for this hemorrhage however each and every health care provider has its own way to manage this situation. Some advise that you may continue your everyday events without worrying at all while others may endorse taking it carefully. Some physicians even suggest refraining from any rigorous activity for the period of pregnancy and bed rest. Surgical procedure will not be an option. Straining and heavy lifting should be avoided.

Some medical professionals pick a ‘wait and watch’ strategy while others select to use medicines. Blood thinners such as: aspirin, Lovenox (inj), Coumadin and Heparin (inj) are utilized to remove the clot as much as possible. Estrogen and Progesterone treatment is also sometimes used to help by reducing such hemorrhagic events.

The present information about prevalence rate of pregnancy loss with a SCH is 1-3%. This low percentage is related to big clots. Most pregnancies grow without further issues. Most clots resolve on their own by means of 20 weeks of being pregnant. The clot either bleeds itself out or the body absorbs it. SCH is a major hazard for pregnancy at early stages because the clot itself can cause a miscarriage. The clot can causes detachment of fetus that may lead to miscarriage ultimately.

Ladies with SCH may just experience intermittent intervals of vaginal bleeding in the course of their being pregnant. This experience would probably be an effect of the clot ‘bleeding out.’ Blood is an irritant to the uterus and cramping is also accompanied with the bleeding. Tampons and sexual activity isn’t typically advocated during bleeding due to possible complications.

In short, SCH is common event during pregnancy but in most cases it does not impart any complication to fetus. However, it is responsibility of patient to keep her routine activities limited to resolve it rapidly. 
Subchorionic Hemorrhage in 2nd Trimester

Subchorionic Hemorrhage in 2nd Trimester (Early Pregnancy)

This condition can also be referred to as subchorionic hematoma. There may be mild to moderate bleeding along with 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 or detaches 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 experience 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 because it is simple to perform and there is not any danger from radiation as with an MRI or CT scan. However, ultrasound uncovers only about 20 percent of all subchorionic hemorrhages 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.
Subchorionic Hemorrhage Miscarriage rates

Subchorionic Hemorrhage Miscarriage Rates (Statistics)

A woman who experiences bleeding in her early pregnancy may just really have a condition referred to as a subchorionic hematoma (SCH). SCH is a pool of blood beneath the chorion or placenta which develops naturally as an embryo implants into the uterine lining.

Even as bleeding in early pregnancy could also be interpreted as a sign of impending miscarriage and must be shared with gynecologist. Such kind of miscarriage is common where the complications are more. During the developmental phase of embryo there might be some leakage of blood due to number of underlying factors. If blood supply becomes insufficient to provide adequate amount of nutrients to embryo then there might be chances that embryo becomes dead at some point of pregnancy.

In some instances, a SCH would lead to miscarriage depending on dimension and vicinity of the hematoma in terms of the embryo. Generally it should be considered as your good luck if you have subchorionic hemorrhage in small amount because large amount of subchorionic bleeding may cause separation of gestational sac from uterine lining resulting into increase risk of pregnancy loss. Moreover, bleeding for longer duration of period is another factor that plays important role in pregnancy complications. So, it is strongly recommended that always consult your health care provider whenever you have such kind of symptoms.

The incidence of SCH is virtually equal between fertility patients and those that have conceived via medical procedure. However, if a patient uses blood thinners like aspirin or heparin, they would be rather more inclined toward a subchorionic bleed due to blood thinning effect of medications. About 30-40% of patients suffering from subchorionic hemorrhage does not discrete its symptoms form other kind of bleeding making it more complicated.

As far as pregnancy is concerned, your health care provide must inform you about the possible risks of bleeding and other possible complications even if you have conceived without medical procedure. Distinguishing the symptoms of subchorionic bleeding earlier makes it less vulnerable to create further complications and healthy pregnancy outcome. Similarly, delaying to get prompt medical intervention in such cases increase the risk of  complications.

It is main obligation of your health care provider to make you well aware of all possible complications that might happen in your pregnancy and describe some cardinal manifestations of those complications for your better understanding in case of emergency or where the prompt surgical or clinical intervention might be required without delaying further.
Subchorionic Hemorrhage Size

Subchorionic Hemorrhage Size - Mild, Small, Large

Bleeding in the first-half of pregnancy occurs roughly in one-fourth (25%) of females and about half of these pregnancies terminate in abortion. The principal reason for vaginal bleeding in early gestation are SCH and rupture of a marginal placental lining. It"s exact etiology is unknown, even though uterine malformations, history of repeated abortions and severe fungal or bacterial infection have been noted as viable predisposing explanations. The size of the hematoma is graded or measured by correlating the size of gestional sac circumference as follows.

  • Small SCH: Indicates less than 1-0.33 of the chorionic sac circumference elevated through hematoma.
  • Moderate SCH: Suggests one third to at least one-half of of the chorionic sac circumference expanded with  hematoma.
  • Large SCH:  Size indicates about two third or bigger of the chorionic sac circumference extended through hematoma.

It has been observed that there were little chances of spontaneous abortion between pregnancies with small and medium sized subchorionic hemorrhage (7.7% and 9.2%, respectively), but the rate gets double when the size is considered to be large (18%).  Researchers have also documented an equivalent case of G3P1A1 Hispanic woman who has been admitted to emergency department (ED) at 6½ weeks pregnancy with complaint of vaginal bleeding of -day length that showed large size intrauterine hematomas could also be acutely detrimental to maternal health within the second trimester.

Ultrasonic evaluation of the placenta is valuable to outline the prenatal prognosis. The detection of a significant SCH on ultrasound raises the risk for miscarriage; stillbirth, placental abruption and preterm labor. Patients with SCH are at larger risk for eventual fetal death even if indicators of fetal existence are obvious at first on sonographic presentation.

Small hematomas on the placental floor, termed as subamniotic hemorrhage, are a usual finding during 18 to 20 weeks of being pregnant in ultrasound and affect subsequent assessment of fetal growth and well-being. Hemorrhage below or on the fringe of the placenta, or in the back of a nearby area of the fetal membranes, is of bigger predicament. In two case studies each neonate survived the prenatal period favorably. One was born vaginally at 32 weeks of gestation following premature preterm rupture of the membranes, and the 2nd was born by way of emergency caesarean part at 37 weeks on the grounds that of a recurrence of post-partum hemorrhage.

Conclusively intrauterine hematoma is a long established finding in first trimester scans. The clinical implication of an intrauterine hematoma for the duration of the primary trimester of being pregnant is not absolutely clear.
Subchorionic Hemorrhage Sign and Symptoms

Subchorionic Hemorrhage Sign and Symptoms

This results from the collection or pooling of blood within the vicinity placed among Chorion and the wall of the uterus. Chorion is the membrane that covers and surrounds the embryo. Subchorionic bleeding happens whilst the placenta detaches from the area where it was attached with membrane. This is called a subchorionic hemorrhage or hematoma. As far as bleeding is concerned, SCH is not only one underlying factor that makes it to happen but there are number of etiological factors that contribute towards bleeding in early pregnancy and only few of them are exactly known.

Most of the women having SCH remains asymptomatic. The recurring ultrasound scan detects the prevalence of SCH in such ladies. Some women do not sense any pain with the bleeding while some may feel abdominal ache and cramps. Presence of blood irritates the uterus and this bring about cramping. There may be abruption of placenta in addition to premature labor. The patient may have threatened abortion

One of the most common subchorionic hematoma symptom in a pregnant woman is bleeding. The quantity and the severity of the bleeding ought to differ from one lady to the other. Some women may have mild to moderate kind of bleeding, whilst others may experience large size bleeding, perhaps with blood clots too. Clinically, if a female reports an excessive quantity of vaginal bleeding because of hematoma, she might also need for proper analysis of a threatened miscarriage. 

Apart from bleeding, some other symptoms of subchorionic hemorrhage include pain and cramps in the lower ababdominal area. In some instances, there can be no outward subchorionic hematoma signs experienced through a woman in any respect and the condition is most effectively diagnosed if the physician conducts a routine ultrasound to test the general fitness and development of the fetus.

Some women have a healthy pregnancy regardless of the symptoms of bleeding. Hematoma having small size usually does not have any effect on the being pregnant. However, if the hematoma is massive or occurs during the early or the beginning segment of the first trimester, there may be a high chance of miscarriage. Large hematomas also result in many critical complications and sometimes result in pregnancy loss. Therefore, women should not ignore the symptoms of bleeding and must consult with health care professional who can also perform an ultrasound to take a look at, which confirms the SCH and the scale and place of the clot.

In short there are no exact symptoms of SCH hemorrhage through which one can easily distinguish it from other forms of hemorrhage during early pregnancyHowever, it is strongly recommended to have digital ultrasound after every 3 weeks to make sure fetus development is up to the mark or otherwise some kind of abnormality like bleeding, clotting or something else must be ruled out.
What Causes Subchorionic Hemorrhage?

What Causes Subchorionic Hemorrhage?

Subchorionic bleeding takes place while the placenta detaches from area where it was anchored with membrane. That is called a subchorionic hemorrhage or hematoma. This detachment leads to pooling of blood within the folds of placental membrane. Subchorionic hematomas are simply one reason of bleeding in pregnant women. Their particular reason is not fully known. Some people may confuse it with spotting that is totally different thing.  According American Pregnancy Association spotting may occur in about 20% of women within 12 weeks of their pregnancies while SCH is common within first and second trimester of pregnancy. 

Some common etiological factors of spotting are:

  • Implantation
  • Extra-uterine growth
  • Sex
  • Hormone imbalance
  • Cervical modifications, together with cervical polyps (small growths)
  • Vaginal Infections

Spotting is though different from subchorionic hemorrhage but it is ideal way to report any form of spotting to your health practitioner, the symptoms are very exclusive from vaginal bleeding. Bleeding that leaves some spots is often a sign of something else. Subchorionic bleeding is one such possibility. You could not even realize you've got one till your doctor performs an ultrasound.

Heavy bleeding also can be a sign of:

  • Ectopic pregnancy
  • Miscarriage
  • Unprecedented circumstance that outcomes in a mass of tissue within the womb
  • Uterine rupture
  • Separation of the placenta from the uterus
  • Preterm exertions (in advance than 37 weeks)


In some cases vaginal bleeding also observed by different symptoms, like intense belly pain and dizziness.Such kind of manifestation might be relate to subchorionic hemorrhage but you always need to have digital ultrasound to make it confirm. Some other reasons for such manifestation are

  • Girls who had just their fertilized eggs implanted.
  • Abrupt uterine rupture
  • Preterm labor.

In short, SCH in small size should be taken lightly because most of the women having small subchorionic hemorrhage have normal and healthy pregnancy outcome but they must be monitored properly thorough out the pregnancy to counter any unknown complication. In spite the fact that small SCH does not pose much harm to fetus but always consult your health care provider whenever you feel any kind of bleeding to rule out risk of complications.
Subchorionic Hemorrhage Treatment

Subchorionic Hemorrhage Treatment

Subchorionic hemorrhage is a pregnancy associated condition that is characterized by formation of a blood clot or pooling of blood among the chorionic membrane and the uterine wall. A subchorionic hematoma is one of the common abnormalities that are detected during an ultrasound test in pregnancy. It's far believed that the effect of a hematoma on pregnancy outcome depends on elements which include the dimensions of the hematoma, age of the expectant mother, and the gestational age of fetus.

Regrettably, there may be no precise or formal treatment for ladies who suffer from hematoma while pregnant. Most doctors recommend taking it easy and getting a lot of bed rest; but, some doctors also recommend pregnant women who have hematoma, to restrict their regular day after day activities. Therefore, lifting weights, strolling too speedy or any kind of rigorous activity should be avoided to decrease the risk of complications.

In case of small size SCH health care provide follow a 'wait-and-watch' approach. Preferably, such blood clots need to resolve before the twentieth week of pregnancy. If the blood clot persists even after the second trimester, then positive self-care measures are suggested to lower the chance of placental abruption. If a pregnant lady experiences stomach ache, cramps, and vaginal bleeding in the 2nd or 1/3 trimester, she must seek medical assistance at her earliest.

Treatment of subchorionic hemorrhage largely depends upon the size of hematoma. Large-sized hematomas pose an extra danger, that is why carefully monitoring of the size and adjustments through ultrasound examinations is essential to the treatment. Usually, women who have large-sized blood clots between placental membranes and uterus are asked to take rest. The self-care measures that are recommended encompass:

Women need to restrict herself from lifting heavy items, as that may place extra pressure on belly muscles and pelvic floor muscles, which can boom the threat of bleeding. They must not indulge in strenuous bodily activities. Rest is highly recommended to drain back the leakage of blood. They should increase their intake of water and fiber to avoid chances of constipation.

In rare instances, health care provider might suggest the usage of blood thinners to wipe the clot out. However, the use of blood thinners may be advised after weighing the pros and cons and keeping the general fitness of the affected person in consideration. If the probabilities of miscarriage are excessive, your health acre provider might advocate usage of estrogen and progesterone remedy decisively. A subchorionic hematoma is one of the usual abnormalities detected during an ultrasound test in being pregnant. It's far believed that the impact of a hematoma at the pregnancy final results depends on factors consisting of the size of the hematoma, age of the expectant mother, and the gestational age of fetus.
Subchorionic Hemorrhage with or without bleeding

Subchorionic Hemorrhage with or without bleeding

Subchorionic hemorrhage (subchorionic hematoma) is the most common sonographic abnormality inside the presence of a live embryo. Vaginal bleeding affects 25% of the girls and is a common finding in first-trimester ultrasonography.

However in some instances, a subchorionic bleed can pose the risk to placenta to split from the uterine wall, and it can be linked to an increased risk of miscarriage and preterm complications. The subchorionic hemorrhage (subchorionic hematoma) occurs between the uterine wall and the chorionic membrane and can leak through the cervical canal. Later within the first trimester and early second trimester, the subchorionic hematoma may partly strip the developing placenta away from its attachment site. Therefore, the diagnosis of patients with this sort of hematoma is worse than the diagnosis of sufferers with hematoma early in first trimester.

Subchorionic hematomas may be hard to identify because they don’t usually result in great symptoms especially when there is smal size. Spotting or bleeding may be a sign, often beginning inside the first trimester. However many subchorionic bleeds are detected at some point of a recurring ultrasound, without there being any significant symptoms or signs.

Ultrasound is the most commonly used technique for determining the presence of a subchorionic hemorrhage due to the fact that it can be easily performed even if patient can't walk and because there's no such risk of radiation as with an MRI or CT scan. But, ultrasound uncovers only 20 percent of all subchorionic hemorrhages, if the blood doesn’t accumulate within the area between the chorionic membrane and the wall of the uterus. An ultrasound is best in locating a subchorionic hemorrhage if it's far completed immediately after there has been an episode of vaginal bleeding. The use of a color Doppler also increases the capacity to find a subchorionic hemorrhage.

SCH Without Bleeding


Some women have massive bleeding while their SCH is developing while others have none. Similarly, few girls have lot of bleeding while their SCH is shrinking,  and others don't have any due to the fact the blood is reabsorbed by the body. A  hematoma can be hard to diagnose and there are a variety of different reasons pf pregnancy associated bleeding (especially within the first trimester). If you’ve been identified with a subchrionic leakage or hematoma, there are a variety of things you could do to help it heal or prevent it from turning into worse.

  • Making sure you’re getting plenty of proper iron through diet.
  • Try to restore you normal vaginal flora to avoid infections.
  • Protein rich diet to strengthen the amniotic sac
  • Hydration
  • No heavy lifting over 3-5 lbs
  • Avoid uterine or cervical stimulants, inclusive of raspberry leaf or evening primrose oil
  • Complete bed rest.
Subchorionic Hemorrhage Ultrasound and Imaging (Tests)

Subchorionic Hemorrhage Ultrasound and Imaging (Tests)

Subchorionic hemorrhage (subchorionic hematoma) is the most common sonographic abnormality within the presence of a live embryo. Vaginal bleeding impacts 25% of all women during the first half of pregnancy and is a usual rationale for first-trimester ultrasonography. Sonographic visualization of a subchorionic hematoma is predominant in a symptomatic woman since pregnant woman with a demonstrable hematoma have a prognosis worse than women with no hematoma. However, small, asymptomatic subchorionic hematomas don't aggravate the patient's prognosis.

Some practitioners sometimes recommend an ultrasound at 6 to 9 weeks to check the presence of subchorionic hemorrhage, however others will most effectively do it if they have got the reason to suspect any sign of subchorionic hemorrhage. In case you have vaginal bleeding early in your pregnancy, your practitioner may perform a routine ultrasound to rule out possible complications. The child's heartbeat will have to be obviously monitored within the 6 weeks of being pregnant (assuming a 28-day menstrual cycle). If one can find the heart beating on the sonogram after 7 weeks, your possibilities of carrying on with healthy pregnancy are greater than ninety seven percent (97%).

If you happen to do not see the heart beating at this point, do not despair. It may be that your cycle is longer than natural and your baby is younger than your practitioner figured. She might want to take a look at once more in a week.

•    To verify the rationale of vaginal bleeding
Bleeding throughout the second half of of your pregnancy may also be due to placenta abnormalities. An ultrasound may aid your practitioner to determine what's going on.

•    To investigate in your baby's progress
Later in pregnancy, if there's any predicament that fetal development is not up to mark, your practitioner may just perform an ultrasound (or a series of them) to measure body growth with regard to age. 

•    To check your amniotic fluid stage
In the event you've been diagnosed with an excessive amount of or too little amniotic fluid, your practitioner will go for common ultrasound for the duration of your third trimester to observe your baby's condition.

•    To verify to your baby's well-being late in the pregnancy
When a woman has high blood pressure and diabetes then risk of complications may two times more than normal instance so your health care provider may perform series of ultrasounds.

Subchorionic Hemorrhage MRI or Magnetic resonance imaging (MRI) is very risky in this regard. A major issue is radiations involved in this kind of imaging that may pose extra risk to fetal development. Normally doctors prefer digital ultrasound over MRI unless otherwise it is necessary to perform.

Doppler ultrasound or Subchorionic Hemorrhage Color Doppler In the course of a Doppler ultrasound, radiologist presses a small handheld gadget (transducer) against your skin over the specified area of your body being examined, relocating from one area to one other as essential. This scan may be performed alternatively as it has high accuracy and sensitivity.
SubChorionic Hemorrhage FAQ's

Subchorionic Hemorrhage Frequently Asked Questions (FAQ'S)

SubChorionic Hemorrhage pregnancy outcome


Subchorionic layer is a membrane in uterus that acts as a protective layer for fetus. Ladies whose sonogram suggest a subchorionic hematoma must be monitored for possible complications and prognosis should done accordingly. Final results of the fetus depends on the size of the hematoma, the mother age, and the fetus's gestational age.. First- or Second-trimester bleeding imparts more complications and makes prognosis difficult. The presence of subchorionic hemorrhage (Sch) in the beginning of pregnancy detected sonographically (subchorionic hematoma) may increase the chances of miscarriage, stillbirth, abruptio placentae, and preterm exertions.

The subchorionic hemorrhage (subchorionic hematoma) builds up between the uterine wall and the chorionic membrane and can leak via the cervical canal. Later during the first trimester and early second trimester, the subchorionic hematoma may also partly strip away the developing placenta from its attachment site. Therefore, pregnancy outcome might be worst in case early hemorrhage as compared to those having subchorionic hemorrhage in later ages.

The subchorionic hematoma may disappear (drain back into circulatory system) with the passage of time if they are small or medium in size but large hematomas do not resolve on their own they must be monitored carefully because in later stages they may cause compression of gestational sac and leading to rupture of membranes with consequent spontaneous abortion.

Subchorionic Hemorrhage and sex


A subchorionic hematoma is just like a mini placental abruption. The 2 vital factors which decide the outcome in this situation, first the dimensions of the clot and secondly the gap from the placenta. The small the dimensions and the extra distant it's miles from placenta, the higher are the possibilities of recuperation.

Nobody is aware of the precise reason of the hematoma. Sexual activity must surely be avoided as it places plenty of pressure and can bring about the worsening of the hematoma. Usually, if the clot/hematoma increases in size, miscarriage occurs with in 16 weeks and if nothing occurs till then, there are high possibilities that the hematoma is absorbed.

Subchorionic Hemorrhage Cramping


Cramping in pregnancy might be common but it should not be taken lightly if it remains consistent during early trimesters. It can be result of brownish spotting due to corpus luteum defect in early pregnancy which requires supplementation of progesterone hormone. Risk associated with such defect is threatened miscarriage, although the such possibility significantly reduces after the passage of primary trimester. Other reasons can be due to placenta previa or some subchorionic hemorrhage. You need to take bed rest, do not climb stairs or raise heavy weights and seek advice from a gynecologist regularly.

Subchorionic Hemorrhage Prognosis


Subchorionic layer is a membrane in uterus that acts as a protective layer for fetus. Ladies whose sonogram suggest a subchorionic hematoma must be monitored for possible complications and prognosis should done accordingly. Final results of the fetus depends on the size of the hematoma, the mother age, and the fetus's gestational age.

Overall prognosis ratio largely depends upon number of factors like age of expectant mother, pregnancy trimester, subchorionic hemorrhage size etc. Clinically, it has been observed that subchorionic hemorrhage that occurs during early pregnancy poses too much risk to fetal growth because they neither absorbs back by circulatory system nor they resolve on their own. After passage of time they puts lot of pressure to gestational sac that ultimately leads to miscarriage. In short, size of subchorionic hemorrhage is the most prominent factor that defines the overall prognosis of pregnancy outcome.
