The placenta previa, also known as the low placenta, occurs when the placenta is inserted partially or completely into the lower part of the uterus and can cover the inner opening of the cervix.
It is usually detected during the second trimester of pregnancy, but this is not a serious problem, as the uterus grows, it moves upwards, allowing the opening of the cervix to be free for delivery. However, in some cases, it may persist, confirmed by ultrasound in the third trimester, around 32 weeks.
- Treatment is indicated by the obstetrician.
- And in case of placenta previa with little bleeding.
- Rest and avoid sex.
- However.
- When the placenta previa bleeds profusely.
- It may need to be hospitalized for fetal and maternal evaluation.
Placenta previa symptoms are more common from the third trimester of pregnancy and include usually painless, bright red vaginal bleeding.
In the face of these symptoms, the pregnanter should go to the hospital immediately for examination by the obstetrician and the obstetrician requests an ultrasound to check the location of the placenta, as these symptoms may be confused with detachment. Find out how the placenta comes off and what to do in these cases.
Diagnosis of the placenta previa is done by ultrasound examination. When such an irregularity is detected in the placenta at the beginning of pregnancy, it is called a low placenta and the placenta is likely to position itself correctly after 30 weeks. In pregnant women who have no symptoms, placenta previa is only discovered by a third trimester ultrasound, which is part of prenatal exams.
Depending on its location in the uterus, the placenta previa can be classified into different types:
Although it doesn’t always cause symptoms, placenta previa can cause vaginal bleeding, risk of preterm birth, or complications during childbirth. This problem is most common in women who are pregnant with twins, multiparas, who have a history of uterine scars, who are over 35 years old, or who have already had a placenta. Understand what the placenta is for and what problems it may develop during pregnancy.
Treatment of the placenta previa should be guided by the obstetrician and may be performed in the hospital or at home, depending on the gestational age and vaginal bleeding of the pregnant woman. Treatment usually involves resting and taking certain care, such as:
Placental acretism is more common in women who have already had a C-section due to placenta previa and often its severity is not known until delivery.
Normal delivery is safe when the placenta is at least 2 cm from the opening of the cervix. However, in other cases or in cases of severe bleeding, a C-section is necessary, as cervical cover prevents the baby from passing and may cause bleeding in the mother during a normal delivery.
In addition, the baby may need to be born earlier than expected, as the placenta may take off too early and interfere with the baby’s oxygen supply.
