Retained Afterbirth (Definition)

The "afterbirth" is the placenta, membranes, and umbilical cord. After the birth of a baby, the placenta should separate from the uterine wall and deliver. It can take as long as 30 minutes for this to happen. If it doesn't separate and deliver during this time-frame it is considered a retained placenta, or retained afterbirth.

How does placenta previa cause preterm delivery?

How does placenta previa cause preterm delivery?

Bleeding and Cntrxns: 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. ...Read more

Will vaginal spotting/bleeding stop placenta previa resolves? Does recurrent bleeding in 2nd tr indicate that placenta previa is unlikely to resolve?

Will vaginal spotting/bleeding stop placenta previa resolves? Does recurrent bleeding in 2nd tr indicate that placenta previa is unlikely to resolve?

2 questions here: Answer to number one, not always. Answer number 2, not always. You will need periodic ultrasound monitoring to follow this issue and, most importantly, if you have significant bleeding, pain, or preterm labor get to hospital right away. Don't plan any trips. You need to be very careful or this may threaten the lives of both you and your baby. Follow your OBs advice and make sure you follow up. ...Read more

What causes retained placenta?

No detachment: After delivery, the placenta is supposed to detach from the wall of the uterus along a specific layer of tissue. Sometimes this tissue layer is partially missing and part of the placenta is tightly adherent to the uterine wall. The placenta is divided into sections called cotyledons. Sometimes one or two cotyledons will be left behind when the rest of the placenta is delivered. Best wishes! ...Read more

How long does bleeding associated with placenta accreta last?

How long does bleeding associated with placenta accreta last?

Delivery at tertiary hospital/trauma center with large blood bank and mfm gyn oncologist surgical care is needed! ...Read more

Can a placenta abruption cause the baby to die?

If big enough, yes: Abruption is a bleed from the placenta; a disruption of either the mother or baby's blood supply. Many causes: trauma, high blood pressure, drugs (cocaine), preterm labor, polyhydramnios. Can be very large or very small, so even US can miss a diagnosis. Symptoms: usually preterm contractions, sometimes vaginal bleed. Fetal monitoring is necessary. Wait, watch; abruption can self-heal sometimes. ...Read more

How will subchorionic hemorrhage affect a delivery?

How will subchorionic hemorrhage affect a delivery?

Risk Preterm Labor: A subchorionic hemorrhage/hematoma is a bleed between the pregnancy and the uterine wall. It is an US finding, that if coupled with vaginal bleeding, can potentially increase the risk of miscarriage/preterm delivery, but w/out vaginal bleeding, it's hard to say. Size matters; worse if bigger (covering ~50% of placental bed) or occurring later. It can heal itself, but you just have to wait/watch. ...Read more

How often does placenta accreta go undiagnosed even after a csection delivery?

How often does placenta accreta go undiagnosed even after a csection delivery?

Placenta accreta: A previously undiagnosed placenta accrete may be diagnosed at the time of a cesarean section. This would occur when the OB is trying to remove the placenta but cannot because it is attached (accreta). On the other hand, if the placenta detaches easily, the uterine cavity is always explored so it would be rare to have an attached placenta left behind but a focal placenta accrete could be missed. ...Read more

Placenta: This means there is a collection of blood between the placenta and the uterine wall- therefore the abruption, the term oligohydramnios basically means low amniotic fluid and can have multiple causes including placenta dysfunction on the side of the mother, of problems with the fetus- problems with the kidneys.

Is it abruptio or placenta previa that bleeds when placenta is low?

Is it abruptio or placenta previa that bleeds when placenta is low?

May be both: A previa is usually painless bleeding when the cervix is changing (dilating) causing bleeding from torn vessels being sheared off. It is a type of abruption although any bleeding from a detaching placenta is strictly called an abruption. These are usually away from the cervix and can be associated with cramping, pain, or heavy bleeding. If you have a previa, let your doc know if you bleed. ...Read more
