2. The degree of calcification of the placenta

The degree of calcification of the placenta is divided into three levels, the highest degree of maturity of the placenta is level 3. The older the gestational age, the higher the placenta's maturity, but in each person the expression is different, depending on For each person, the process of calcification takes place quickly or slowly. The older the gestational age, the more calcified clusters.
On ultrasound, the placenta will be evaluated for calcification with the following levels:
Grade 0: gestational age about 31 ± 1 week; Grade 1: gestational age 34 ± 3.2 weeks; Grade 2: gestational age 37.6 ± 2.7 weeks; Grade 3: gestational age 38.4 ± 2.2 weeks; When the third degree of calcification shows that the fetal lung function has begun to perfect, the baby can gradually adapt and can fully live when out in the environment.

3. When is placental calcification dangerous?


Most pregnant women, when reading the ultrasound results, find that they have placental calcification, they are very worried, afraid that the placenta will calcify quickly, the nutrition through the placenta will be slower to nourish the fetus. However, most placental calcification is not a cause for concern. This only indicates the maturity of the fetus, but does not mean that the placenta is degenerated.
But in some cases, a large accumulation of placental calcification can cause some of the following effects:
Accumulation of calcium in certain areas will cause fibrosis in that area and cause blockage of some blood vessels in the placenta . If stage 3 calcification occurs from early weeks of pregnancy, it will make the transmission of nutrients from mother to baby will be poor, the fetus in the abdomen can absorb less nutrients, leading to cell malnutrition. pregnant. Postpartum pregnancies and highly calcified placenta are at higher risk of fetal distress due to severe hypoxia. These fetuses will also have a mortality rate 3 times higher than other fetuses. If it lasts until 42 weeks, placental calcification will occur even faster. Blood concentration in the placenta will decrease, making oxygen exchange difficult. This condition, if prolonged, can lead to fetal distress, fetal death during labor or death shortly after birth, or affect the development of the baby due to lack of oxygen in the brain.
