Placental pathology (velamentous insertion, succenturiate lobes, bipartite i.e. bilobed placenta etc.) [13] Baby is in an unusual position: breech (buttocks first) or transverse (lying horizontally across the womb). Placenta previa is itself a risk factor of placenta accreta. Alcohol use during pregnancy was previously listed as a risk factor ...
Placenta previa is a condition that occurs when the placenta fully or partially covers the cervix. [13] Placenta previa can be further categorized into complete previa, partial previa, marginal previa, and low-lying placenta, depending on the degree to which the placenta covers the internal cervical os.

The onset of the disease within the first trimester leads to preterm delivery of a premature baby. [14] Preeclampsia is diagnosed in 3-5% of pregnancies that place them at risk of developing placental disease. [ 6 ]
The accumulating blood pushes between the layers of the decidua, pushing the uterine wall and placenta apart. When the placenta is separated, it is unable to exchange waste, nutrients, and oxygen, a necessary function for the fetus's survival. The fetus dies when it no longer receives enough oxygen and nutrients to survive. [9]
An impaired placenta cannot support the pregnancy and this may lead to the loss of a chromosomally normal baby. [5] On the other hand, an apparently normal diploid fetus may experience problems with growth or development due to the effects of uniparental disomy (UPD). Intrauterine growth restriction (IUGR) has been reported in a number of CPM ...
Histopathology of placenta with increased syncytial knotting of chorionic villi, with two knots pointed out. The following characteristics of placentas have been said to be associated with placental insufficiency, however all of them occur in normal healthy placentas and full term healthy births, so none of them can be used to accurately diagnose placental insufficiency: [citation needed]
Besides placenta previa and placental abruption, uterine rupture can occur, which is a very serious condition leading to internal or external bleeding. Bleeding from the fetus is rare, but may occur with two conditions called vasa previa and velamentous umbilical cord insertion where the fetal blood vessels lie near the placental insertion site unprotected by Wharton's jelly of the cord.
