Question 1

subchorionic hematoma size of 3.1x1.6x1.3 cm was discovered at my 8 week ultrasound. is this considered large & what are the chances of it growing, so far no bleeding or cramps?

Accepted Answer

: Hematoma size is more than 25% of the average gestational sac volume at 8 weeks so this hematoma is considered high risk of miscarriage. So far you have been safe without bleeding, please limit you activity and follow closely with your OB doctor.

Question 2

what are the chances of a medium sized subchorionic hematoma resolving and ending in a normal pregnancy? i am currently 7 weeks 6 days pregnant. i had my first prenatal visit 4 days ago and everything looked good. two days ago after getting out of the sho

Accepted Answer

To : To answer your questions:  yes, there is a chance it will resolve on its own.  There is definitely a chance of a miscarriage.  With a medium sized subchorionic hemorrhage, your changes of a successful pregnancy are most likely around 50-50, but I have definitely seen it happen.  A subchorionic hemorrhage does not necessarily put you at any greater risk of placental abruption, which is a different medical condition.

You have done everything correctly.  Be sure that you know that this is a random occurrence and just one of those things that happens for no reason.  I will wish you the best.

Question 3

is subchorionic hematoma linked with other risks?

Accepted Answer

Adverse effects of : SCH on pregnancy outcomes depend on size, gestational age, &amp; maternal age. Fetal  growth restriction, placental abruption, pre-eclampsia, prematurity, &amp; fetal distress may occur. If there is significant decrease in  blood flow &amp; nutrients to the fetus , brain &amp; other organ development may be altered. Anxiety doesn't help. Monitoring &amp; treatment by a Fetal-Maternal Medicine specialist do help.

Question 4

can sex cause subchorionic hematoma to get bigger?

Accepted Answer

No really: We frequently advise those who have a subchorionic hematoma to avoid intercourse to help avoid bleeding. There is not evidence that sex makes one bigger.

Question 5

i am 6w3d and my scan today said perisac hematoma measuring 2.8 x 0.4 x 0.8 cm... is this the same as a subchorionic hematoma? what's the difference?

Accepted Answer

This: Perisac hematoma should be the same as a subchorionic hematoma. Just different nomenclature.

Question 6

what are the risks associated with a subchorionic hematoma?

Accepted Answer

Problems: Subchorionic bleeding is usually placental in origin, making a stable bleed a stable placental abruption.  Subchorionic bleeding is associated with elevated rates of miscarriage, preterm labor, placental abruption, and preterm rupture of membranes.   Many cases will turn out ok though.  An OB should be involved, and serial ultrasound can be helpful in following the bleed.

Question 7

is it normal to pass a clot if i have a subchorionic hematoma?

Accepted Answer

Pregnancy bleed: Subchorionic hematomas are small blood collections behind the placenta. It is common in the first trimester of pregnancy. Trapped blood will either reabsorb, find a path way out or simply stay in place. If it can find a pathway out then the patient will see bleeding. Close follow up with your Obgyn is warranted.

Question 8

how long should i expect a subchorionic hematoma to bleed?  when should i start to worry if it does not? (i have already seen a doctor about it)

Accepted Answer

Uncertain: as long as the fetus is growing appropriately, that is the best you can hope for. Clearly, if you have other medical disorders, these should be under control.
Best wishes

Question 9

is 3.2 x 1.6 x 2.3 retroplacental marginal hematoma and 1.2 x 0.6 x 1.9 cm subchorionic hematoma in the fundus big for 14 weeks? is it dangerous?

Accepted Answer

Monitoring: Subchorionic hematoma are small areas of blood collected behind the placenta. They increase the risk of bleeding and  miscarriage slightly. The further along in pregnancy the less the risk of pregnancy loss. Continued monitoring with serial ultrasound is warranted. 3 cm is moderate size but size is relative in these cases as the size does not necessarily correlate with risk.

Question 10

how long should i expect a subchorionic hematoma to bleed?  when should i start to worry if it does not stop? (i have already seen a doctor about it)

Accepted Answer

Continue  care: This is not a simple question. Continue to see your physician for care and explanation of how you feel.
