Placenta Previa is a condition where the placenta lies low in the uterus and partially or completely covers the cervix.
Placenta previa can be detected by ultrasound.
Types of placenta previa:
- Complete placenta previa refers to the situation in which the placenta completely covers the opening from the womb to the cervix.
- Partial placenta previa refers to the placenta that partially covers the cervical opening (since the cervical opening is not dilated until time for delivery approaches, bleeding may occur after the cervix has begun to dilate).
- Marginal placenta previa refers to a placenta that is located adjacent to, but not covering, the cervical opening.
- The term low-lying placenta or low placenta has been used to refer both to placenta previa and marginal placenta previa.
Causes of placenta previa:
- chronic endometritis
- uterine fibroids
- multiple fetus
- scar on the uterus after cesarean section, myomectomy
- frequent abortions, curettage of the uterus in history
- sudden painless bleeding of various intensity
sudden painless bleeding of various intensity
Hospitalization is required. Strict bed rest
Throughout pregnancy, careful monitoring of the condition of the fetus and the woman is necessary.
Bleeding can occur at any time, depends on the volume of which the clinical picture unfolds and the tactics of further management are chosen. With significant blood loss, an emergency Caesarean section is necessary, regardless of the duration of pregnancy.
Massive bleeding can be complicated by fetal death, the development of intravascular coagulation syndrome, the critical condition of the woman.
In the case of placenta previa in the uterine scar, a hysterectomy may be necessary.
