placental grading

Placental grading is a method for indicating the maturity of the placenta and the fetus. The placenta level is 0~III. Generally, the placenta above level II indicates that the fetus is mature. If the placenta reaches level III, the placenta is mature and tends to age. Affecting the function of the placenta is not conducive to the absorption of nutrients by the fetus. The placenta matures too fast or too slow, and the pregnancy cycle is insufficient to reach grade III. It may cause fetal nutrition and insufficient oxygen due to aging of the placenta, leading to premature birth. Basic Information Specialist classification: maternity check check classification: ultrasound Applicable gender: whether women are fasting: not fasting Tips: Empty the bladder before checking and remove the metal decoration. Normal value Grade 0 placental fluff plate is a bright straight line, the body is uniform and fine particles, no base is seen. More than 28 weeks before pregnancy; The grade I placental fluff plate is a lightly undulating bright line, the placenta has a slightly coarser granule, the echo is slightly stronger, and the basal layer is still present, and the gestational age is 29-36 weeks. Grade II placental fluff plate excised, extending to the placenta parenchyma but not reaching the basal layer, the placental parenchyma particles became thicker, a strong short columnar echo appeared, and the basal layer may have irregularly thick strip echoes, parallel to the muscle wall More than 36-40 weeks of gestational age; Grade III placental villus notch has reached the basal layer, and multiple strong echogenic rings appear in the placenta. There may be no echogenic cuvettes inside, and sometimes there are reflective enhanced calcifications. 28 weeks 0 to I 36 weeks I to II 40 weeks II to III Clinical significance Abnormal results: the placenta matures too fast or too slow, the pregnancy cycle is insufficient to reach grade III, may cause fetal nutrition, insufficient oxygen due to aging of the placenta, leading to premature birth. The people who need to be examined are women in the middle and late pregnancy. High results may be diseases: expired birth, early pregnancy considerations Before the test: empty the bladder and remove the metal decoration; When checking: Relax your body and actively cooperate with your doctor.
