Placenta previa is a complication of pregnancy in which the placenta is implanted in the lower part of the uterus, near the cervix, or completely obstructing the cervix. In this sense, there are different types of placenta previa:
- Low-lying placenta
- the placenta is near the opening of the cervix, on one side, but does not cover it.
- Marginal previa
- the placenta is on one of the edges of the cervix orifice, but does not cover it either.
- Partial previa
- the placenta obstructs part of the cervical opening.
- Complete previa
- the placenta covers the entire cervical opening, which prevents the exit of the fetus in a natural delivery.
