Standards for placenta grading level 2

The health of the placenta after pregnancy is of great concern to every pregnant woman, because the health of the placenta determines the health of the fetus, so many pregnant women want to fully understand the standards of placenta grade 2. The following content provides a detailed introduction to this aspect for many pregnant women. You can see the detailed answers below.

Grading Standards

Grannum placenta grading system divides placental maturity into four grades:

Grade 0 placenta: The villous plate is a straight bright line, the substance is uniform and fine particles, and the base is not visible. It usually occurs before 28 weeks of pregnancy.

Grade 1 placenta: The villous plate is a slightly undulating bright line, the placental parenchyma is slightly coarse, the echo is slightly strong, and the basal layer has not yet appeared. It usually appears at 29-36 weeks of gestation.

Grade 2 placenta: The villous plate is notched, extending to the placental substance but not reaching the basal layer. The placental substance particles become coarser, and strong short columnar echoes appear. Irregular strong strip echoes may appear in the basal layer, parallel to the muscle wall. The gestational age is mostly 36-40 weeks.

Grade 3 placenta: The villous notch has reached the basal layer, and the placental substance has multiple strong echo rings, and there may be anechoic pools inside, and sometimes calcification foci with enhanced reflection can be seen.

Amniotic fluid index method:

During the B-ultrasound examination of the placenta, the single maximum vertical depth of the dark area of ​​amniotic fluid (AFD) is used to indicate the amount of amniotic fluid. If it exceeds 7CM, it can be considered as polyhydramnios. If the amniotic fluid index method (AFI) exceeds 18CM, it is polyhydramnios. (The measurement of the amniotic fluid index is centered on the umbilicus, and the abdomen is divided into four quadrants. The maximum dark area of ​​amniotic fluid in each quadrant is measured separately, and the four data are added together.) The B-ultrasound diagnosis of oligohydramnios uses the maximum amniotic fluid depth of less than or equal to 3CM as the diagnostic standard. The amniotic fluid index method is more accurate than AFD. AFI less than or equal to 8CM is used as the critical value for diagnosing oligohydramnios, and AFI less than or equal to 5CM is the absolute value for diagnosing oligohydramnios.

Through the above comprehensive introduction, I believe that many pregnant women have fully understood the standards for placenta grade 2. After a comprehensive understanding, in order to ensure that there will be no placenta problems during pregnancy, while doing all kinds of examinations, if there are problems with the placenta, go to the hospital for comprehensive examination and treatment in time.
