What does placenta previa mean

summary

The fetus survived in the mother's stomach for 10 months before it came out. The fetus is closely related to the placenta. But the placental position is not right, the impact on the fetus is great. Now let's take a look at the meaning of placenta previa.

What does placenta previa mean

First, the normal attachment of the placenta is in the posterior, anterior or lateral wall of the uterine body. If the placenta is attached to the lower uterine segment or covered in the cervix, the position is lower than the fetal presentation, it is called placenta previa. Placenta previa is one of the main causes of bleeding in late pregnancy, which is a serious complication of pregnancy.

Second: it is more common in multipara, especially in multipara. Clinically, placenta previa can be divided into three types: one is complete placenta previa or central placenta previa, the inner mouth of the cervix is covered by placental tissue; the other is partial placenta previa, the inner mouth of the cervix is partially covered by placental tissue; the third is marginal placenta previa, the edge of the fetal disc is attached to the lower uterine segment, not beyond the inner mouth of the cervix.

Third: Endometrial dysplasia or endometrial lesions: pregnant women have experienced uterine body surgery or multiple curettage, causing endometrial damage, inflammation, resulting in scar formation. Due to the local thinning of the damaged endometrium and poor blood supply, when the fertilized egg is implanted, the placenta with insufficient blood supply extends to the lower uterine segment, resulting in placenta previa.

matters needing attention

Bad living habits, diet and so on can lead to placenta previa. Placenta previa is dangerous. The impact on the fetus and mother is enormous. Placenta previa can be absolutely bed rest, termination of pregnancy, or medication.
