In this case, the placenta covers the cervix partially or completely. WINCHESTER CALCIFICATION of the placenta is recognized as a common occurrence by obstetricians and pathologists, and if one examines a number of placentae after birth with the naked eye or a hand lens, it can be seen in the form of small greyish-white gritty particles scattered over the maternal surface. Many researchers regard placental calcification as a normal ageing process, rather than a change related to a disease or ailment. Extent and tissue-specific patterns of vascular calcification are predictors of cardiovascular morbidity and mortality.

Abstract. Thus, examination of the placenta may yield information on the impact of maternal disorders on the fetus or the cause of preterm delivery, fetal growth restriction, or neurodevelopmental impairment. Introduction: Placental calcification, identified before the 36th week of gestational age, is known as premature placental calcification (PPC). However, calcification before the 37 th week or the maturity of the foetus can pose a problem to the baby. PPC could be a clue for the poor fetal outcome. In most cases, placental calcification is just an indication of the normal level of maturation of a near term fetus. Placental grading (Grannum classification) refers to an ultrasound grading system of the placenta based on its maturity. Calcification placenta. (1993). The placenta is usually described as going through four grades, from 0 (most immature) to III . Thus, diseases and disorders that affect the state of the endothelium, the tone and fragility of the vascular wall, the blood clotting system lead to a heart attack. The pattern of calcification (precipitation of calcium hydroxyapat_te) is similar to that seen in other aging tissues, and is probably a response to cell death and diminished blood circulation in localised regions of the placenta. The placenta is what attaches to the umbilical cord and provides vital nutrients to the developing fetus. Placental infarction (sometimes called placental cerebral infarction) is the interruption in blood flow between the placenta and the baby.

The term "calcification" refers to the accumulation of calcium in parts of the body where it should not accumulate, causing hardening of the tissues in question. Calcifications in the placenta occur normally and should not arouse suspicion of disease in the mind of the radiologist or obstetrician. When palpating the maternal abdomen, placental function is crudely "assessed" by estimating the amniotic fluid volume. Aseptic pancreatic necrosis, unrelated to acute pancreatitis; Atrophy of pancreas; Calculus of pancreas; Cirrhosis of pancreas; Fibrosis of pancreas Causes of calcification. In instances of chronic inflammation, such as pancreatitis from excess alcohol .
