why is there bleeding with placenta previa?

Question

My daughter is 27 weeks pg. She has bleeding daily for about 5 weeks she has b she has circumvalate placenta and partial previa can she carry to term?

Answer 1

Placenta: When placenta is on lower uterine segment, it is called placenta previa. When plans is completely covering the internal os it is complete placenta previa. When the lower segment of uterus gets stretched in last trimester, it distrupts the placenta to cause bleeding.

Answer 2

Maternal vessels.: Placenta previa means that the internal cervical os is covered by trophoblast. When labor occurs, or the amniotic membranes rupture, the placenta starts detaching from the lower uterus, so the maternal blood circulating through the placenta exits from its proper place and manifests as vaginal bleeding (not fetal blood).

Answer 3

Leaky vessels: Previa: Placenta overlies the cervix/birth canal. Gr 1 means placenta is close, Gr 4 means it's directly overlying/blocking the baby's exit -- high chance of preterm labor & bleeding; you'd need a C/S at 36-37wks. More common in woman w/ hx of C/S & smoking. Not much you can do but wait. If dx'ed early, the uterus still grows/stretches and a placenta can migrate away even in 3rd tri. Follow w/ US.

Answer 4

Placenta prevIa: The stretching of lower uterine segment causes the disruption in blood supply to the plaventa. The blood usually comes out of the internal os. So this bleeding is painless. Rarely is there is collection of blood behind placenta than it can be painful.

Answer 5

No contractions.: Because the bleeding does not involve the contractile part of the uterus, only the placenta over the cervix. The placenta is devoid of innervation, therefore the mother does not experience pain in bleeding previa unless preterm labor is also present.

Answer 6

Leaky placental vsls: Previa: Placenta overlies the cervix/birth canal. Gr 1 means placenta is close, Gr 4 means it's directly overlying/blocking the baby's exit -- high chance of preterm labor & bleeding; you'd need a C/S at 36-37wks. More common in woman w/ hx of C/S & smoking. Not much you can do but wait. If dx'ed early, the uterus still grows/stretches and a placenta can migrate away even in 3rd tri. Follow w/ US.

Answer 7

Yes: When placenta previa is partial or incomplete where it does not cover the internal os, it is possible.

Answer 8

Common.: Many cases of placenta previa bleed in the third trimester, however many cases do not bleed at all, or only at term.

Answer 9

Bleeding: Placenta previa is the placenta implanting over the internal opening of the cervix, and is a very serious problem. It will necessitate you having a caesarean section, as you will not be able to have a vaginal birth. As to bleeding, it can be very serious, and should be reported to your doctor immediately.

Answer 10

Placenta previa: Usually bleeding associated with placenta previa is painless. Rarely, if there is separation of placenta and blood is collected retroplacentally, it can be painful.

Answer 11

Blood => irritation: Previa: Placenta overlies the cervix/birth canal. Gr 1 means placenta is close, Gr 4 means it's directly overlying/blocking the baby's exit -- high chance of preterm labor & bleeding; you'd need a C/S at 36-37wks. More common in woman w/ hx of C/S & smoking. Not much you can do but wait. If dx'ed early, the uterus still grows/stretches and a placenta can migrate away even in 3rd tri. Follow w/ US.

Answer 12

See below: It's variable and unpredictable.

Answer 13

Varies: Placenta previa is a condition in which the placenta implants directly over the cervix and blocks the birth canal. For this reason, women with placenta previa require a c-section. Since the placenta is exposed more, it is more prone to bleeding as well. Bleeding ranges from continuous or occasional spotting to torrential hemorrhage that could threaten the lives of both mother and baby.

Answer 14

Unknown: Previa: Placenta overlies the cervix/birth canal. Gr 1 means placenta is close, Gr 4 means it's directly overlying/blocking the baby's exit -- high chance of preterm labor & bleeding; you'd need a C/S at 36-37wks. More common in woman w/ hx of C/S & smoking. Not much you can do but wait. If dx'ed early, the uterus still grows/stretches and a placenta can migrate away even in 3rd tri. Follow w/ US.

Answer 15

Yes : There is no surgical or mefical treatment yo correct placenta previa however sometimes the placenta can change or move so that it no longer overlies the opening of the cervix if you have true placenta previa it needs to be closely monitored especially the closer you get to going in labor as at that time your cervix will dilate and can cause severe bleeding.
