An abruptio placentae is a premature separation of the placenta from the uterine wall.
Placenta abruptio or placental abruption is abnormal separation of the placenta from the uterine wall.
Separation of the placenta from the uterine wall beginning at the outermost edge of the placenta. Blood from the implantation site exits immediately through the vagina followed by the placenta, which descends sideways into the vagina.

Yes, using cocaine in particular can cause the placenta to separate from the uterus during pregnancy (placental abruption).
it increases the risk for post partum hemorrhage and infection The person who delivers the placenta should ensure it is complete so this doesn't happen. an operation may be required to remove the remaining placenta.
There are a number of things that may make your placenta feel hard and have pain. In most cases, this may be due to abruption or this could be early labor signs.
The embryo and placenta grow side by side and are attached via the umbilical cord - the placenta attaches to the uterine wall as it develops after the embryo implants in the uterine lining. Some women have spotting and slight cramps when the embryo attaches to the uterine lining.

the causes of polyhydromnious is meternal cause and fetal cause and itis effects it may cause premature separation of placenta.
In circumvallate placenta, the placenta presents with elevated margins because the location as to where the placenta attaches at implantation is too small for the entire placenta to attach causing the placental edges to be loose. The could possibly cause the placenta to function poorly and not supply the baby with adequate o2. The placenta ends curve and curl inwards. The problem is if the placenta continues to develop in more and more curve and then separates from the uterus. That would mean the need for an emergency delivery of the baby so it becomes very critical the earlier this happens. I don't know the odds of the placenta separating, and nothing may happen at all, it's just important to make sure the baby is getting the nourishment it needs via the placenta and act immediately should any bleeding occur. The doctor said it's not common to see this and there is nothing I have done in the past or anything I can do to avoid problems with separation.
