Placental insufficiency Placental insufficiency can affect the fetus, causing Fetal distress. Placental insufficiency may cause oligohydramnios, preeclampsia, miscarriage or stillbirth. Placental insufficiency is most frequent cause of asymmetric IUGR.
Eclampsia fetal distress. Placental bleeding, and placental abruption may also occur.
Placental infarction Small placental infarcts, especially at the edge of the placental disc, are considered to be normal at term. Large placental infarcts are associated with vascular abnormalities, e.g. hypertrophic decidual vasculopathy, as seen in hypertension. Very large infarcts lead to placental insufficiency and may result in fetal death.
Placental disease A placental disease is any disease, disorder, or pathology of the placenta. The article also covers placentation abnormalities, which is often used synonymously for placental disease.
Placental insufficiency The following tests have been promoted as supposedly diagnosing placental insufficiency, but all have been unsuccessful at predicting stillbirth due to placental insufficiency:
Placental alkaline phosphatase Alkaline phosphatase, placental type also known as placental alkaline phosphatase (PLAP) is an allosteric enzyme that in humans is encoded by the "ALPP" gene.
Placental abruption Risk factors for placental abruption include disease, trauma, history, anatomy, and exposure to substances. The risk of placental abruption increases sixfold after severe maternal trauma. Anatomical risk factors include uncommon uterine anatomy (e.g. bicornuate uterus), uterine synechiae, and leiomyoma. Substances that increase risk of placental abruption include cocaine and tobacco when consumed during pregnancy, especially the third trimester. History of placental abruption or previous Caesarian section increases the risk by a factor of 2.3.
Placental abruption In the Western world, maternal deaths due to placental abruption are rare. The fetal prognosis is worse than the maternal prognosis; approximately 12% of fetuses affected by placental abruption die. 77% of fetuses that die from placental abruption die before birth; the remainder die due to complications of preterm birth.
Placental abruption Placental abruption is suspected when a pregnant mother has sudden localized abdominal pain with or without bleeding. The fundus may be monitored because a rising fundus can indicate bleeding. An ultrasound may be used to rule out placenta praevia but is not diagnostic for abruption. The diagnosis is one of exclusion, meaning other possible sources of vaginal bleeding or abdominal pain have to be ruled out in order to diagnose placental abruption. Of note, use of magnetic resonance imaging has been found to be highly sensitive in depicting placental abruption, and may be considered if no ultrasound evidence of placental abruption is present, especially if the diagnosis of placental abruption would change management.
Placental lactogen For information on the human form, see human placental lactogen.
Placental insufficiency Placental insufficiency should not be confused with complete placental abruption, in which the placenta separates off the uterine wall, which immediately results in no blood flow to the placenta, which leads to immediate fetal demise. In the case of a marginal, incomplete placental abruption of less than 50%, usually weeks of hospitalization precedes delivery and outcomes are not necessarily affected by the partial abruption.
Placental abruption Placental abruption occurs in approximately 0.2%-1% of all pregnancies. Though different causes change when abruption is most likely to occur, the majority of placental abruptions occur before 37 weeks gestation, and 14% occur before 32 weeks gestation.
Elizabeth M. Ramsey Dr. Ramsey's work had significant implications for understanding the development of the placenta and problems with placental development, including placental abruption.
Placental insufficiency 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:
Apatemyidae Apatemyidae is an extinct family of placental mammals that took part in the first placental evolutionary radiation together with other early mammals such as the leptictids.
Fauna of New Guinea The native placental mammals are solely represented by the rodents and bats. There are approximately the same number of placental species as marsupials and monotremes.
Eclampsia Placental hypoperfusion is linked to abnormal modelling of the fetal–maternal placental interface that may be immunologically mediated. The invasion of the trophoblast appears to be incomplete.
Gestational trophoblastic disease Hydatidiform moles are abnormal conceptions with excessive placental development. Conception takes place, but placental tissue grows very fast, rather than supporting the growth of a fetus.
Placental microbiome The placental microbiota varies between low birth weights and normal birth weights.
Placental insufficiency Placental insufficiency can be induced experimentally by bilateral uterine artery ligation of the pregnant rat.
