Does placenta previa require hysterectomy?

Multiple caesarean sections or multiple miscarriages, endometrial lesions and other reasons may lead to placenta previa. Placenta previa does not necessarily require hysterectomy, but you must pay more attention during pregnancy, avoid doing physically strenuous activities, pay more attention to rest, and have regular check-ups. If you have symptoms of bleeding, you should go to the hospital for examination immediately.

Why does the placenta previa occur in pregnant women?

1. Endometrial lesions of the uterine body. Such as puerperal infection, multiple births, multiple curettages and cesarean sections, which cause endometritis or endometrial damage, resulting in incomplete growth of blood vessels in the uterine decidua. When the fertilized egg is implanted, the blood supply is insufficient, and the placenta area is expanded to extend to the lower part of the uterus in order to absorb enough nutrients.

2. The placenta area is too large. For example, the placenta area of ​​twins is larger than that of a single fetus and reaches the lower part of the uterus. The incidence of placenta previa in twin pregnancies is twice as high as that in single pregnancies.

3. Abnormal placenta. In the case of accessory placenta, the main placenta is in the body of the uterus, while the accessory placenta can reach the lower part of the uterus near the internal os of the cervix.

4. The trophoblast of the fertilized egg is slow to develop. When the fertilized egg reaches the uterine cavity, it has not yet developed to the stage where it can implant and continues to migrate into the lower segment of the uterus, where it grows and develops to form a placenta previa.

The dangers of placenta previa

Placenta previa is one of the serious complications of pregnancy, which is very harmful to both mother and child.

1. Hemorrhage during and after delivery. When a cesarean section is performed for a placenta previa attached to the anterior wall of the uterus, bleeding will increase significantly if the uterine incision cannot avoid the placenta. After the fetus is delivered, the contraction force of the muscles in the lower part of the uterus is poor, and the attached placenta is not easy to separate. Even after separation, postpartum hemorrhage is prone to occur because the open blood sinuses are not easy to close.

2. Anemia and infection. Most women suffer from anemia and weak constitution due to repeated bleeding, and the placenta previa detaches on the internal os of the cervix, so they are prone to infection during the postpartum period.

3. Placenta accreta. Placenta previa may occasionally be combined with placenta accreta, resulting in incomplete placental separation and heavy bleeding. Sometimes the uterus needs to be removed to save the life of the pregnant woman.

4. Poor perinatal prognosis. Excessive bleeding can lead to fetal distress or even death from lack of oxygen. Sometimes, in order to save the life of the pregnant woman or fetus, the pregnancy needs to be terminated early, resulting in an increase in the rate of premature birth.

Placenta previa daily precautions

Expectant mothers with placenta previa should pay attention to their daily lives to avoid vaginal bleeding and other conditions that may endanger the lives of mother and child.

1. Avoid lifting heavy objects: In the middle and late stages of pregnancy, you should be more careful about the details of your life. It is not advisable to lift heavy objects or exert force on your abdomen to avoid danger.

2. Suspend sexual activity depending on the situation: If there are bleeding symptoms or the pregnancy enters the late stage, sexual activity should not be performed. In addition, patients with milder placenta previa should also avoid too intense sexual activity or actions that compress the abdomen.

3. Don’t be too tired: Pregnant women with high-risk pregnancies should rest more to avoid being too tired and affecting the smoothness of pregnancy and delivery.

4. Pay attention to fetal movement: Pay attention to whether the fetal movement is normal every day. If you feel that the fetal movement is significantly reduced, you need to see a doctor as soon as possible.

5. Do not over-exercise: Excessive exercise may also cause placenta previa bleeding or other symptoms. Therefore, this type of pregnant woman should not engage in strenuous exercise.

6. Choose a suitable prenatal check-up hospital: If you are a patient with third or fourth grade placenta previa, it is best to choose a large hospital or medical center for prenatal check-up, so that if problems such as premature birth and heavy bleeding occur, they can be dealt with immediately.

7. Seek medical attention immediately if you have bleeding: If you have bleeding symptoms, no matter how much blood is flowing, you should see a doctor immediately. If you meet a new obstetrician, you should also proactively inform him or her that you have a placenta previa.
