Anterior placenta is a relatively common clinical complication of pregnancy. Placenta praevia can cause vaginal bleeding during pregnancy and can seriously affect the health of the pregnant woman’s fetus. Placenta praevia in early pregnancy is known as a low placental state. A placenta hypoplastic state in early pregnancy can also cause a small amount of vaginal bleeding. As the pregnancy progresses, the uterus gradually increases in size. Placenta hypoplasia can be corrected gradually as the uterus increases in size. However, in some pregnancies, the placenta remains low as the uterus increases in size. This placenta hypoplasia can progress to placenta praevia. The state of placenta praevia is very stable in the middle and late stages of pregnancy. There is no clinical way to correct placenta praevia in the mid to late stages of pregnancy. Patients are advised to consult their local hospital immediately for ultrasound to determine the position of the placenta if vaginal bleeding occurs during pregnancy. If placenta praevia is found, there is no need to be overly concerned. Most cases of placenta praevia will improve after treatment with fetal preservation and can be expected to deliver at full term after treatment. In conclusion, there is no effective clinical method to correct placenta praevia, and if necessary, treatment with fetal preservation is sufficient.
