Placental calcification

Normal placenta does not have calcifications. When there are only diseases such as expired pregnancy, pregnancy-induced hypertension, and chronic nephritis, its tissue cells undergo degeneration and necrosis due to ischemia and hypoxia, and calcium deposits on the necrotic site, forming placental calcification. Therefore, calcification of the placenta means that the function of the placenta to transport nutrients is reduced. When the calcification is severe, the placenta cannot provide oxygen and nutrition to meet the fetal development, the fetus may be distressed in the uterus, growth and development may stop, and even death, so the placental calcification is harmful to the fetus.
