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]
Intrauterine hypoxia can be attributed to maternal, placental, or fetal conditions. [12] Kingdom and Kaufmann classifies three categories for the origin of fetal hypoxia: 1) pre-placental (both mother and fetus are hypoxic), 2) utero-placental (mother is normal but placenta and fetus is hypoxic), 3) post-placental (only fetus is hypoxic).
Normally, ovine placental mass increases until about day 70 of gestation, [45] but high demand on the placenta for fetal growth occurs later. (For example, research results suggest that a normal average singleton Suffolk x Targhee sheep fetus has a mass of about 0.15 kg at day 70, and growth rates of about 31 g/day at day 80, 129 g/day at day ...
This commonly occurs around 32 weeks of gestation, but can be as early as late mid-trimester. [8] More than half of women affected by placenta praevia (51.6%) have bleeding before delivery . [ 9 ] This bleeding often starts mildly and may increase as the area of placental separation increases.
A placental disease is any disease, disorder, or pathology of the placenta. [ 1 ] [ 2 ] Ischemic placental disease leads to the attachment of the placenta to the uterine wall to become under-perfused, causing uteroplacental ischemia.
