The placenta should be in the normal range when it is more than 2cm away from the C-section scar. For pregnant mothers who have a history of cesarean section, it is generally recommended to wait two years after the cesarean section before conceiving a new life, because if the interval between two pregnancies is too short, it will lead to the fertilized egg to be deposited in the scar site, resulting in cesarean section keloidal pregnancy, which is prone to placental implantation, which will have a serious impact on both the mother and the fetus. Scar site pregnancy needs to be treated promptly after discovery. Early pregnancy can be treated conservatively with methotrexate if there is no abdominal pain, little vaginal bleeding, and the mass has not ruptured. For termination of pregnancy, interventional embolization of the uterine artery is required, followed by fetal extraction and local excision of the lesion. If the pregnancy is detected at the time of delivery during pregnancy, the woman must consult a specialized doctor for further examination to check the degree of implantation of the placenta. Specialized measures are taken according to the situation. Pregnant women should pay attention to the prenatal examination during pregnancy, actively listen to the advice of professional doctors to do a comprehensive nursing care, pay attention to more rest, at the same time, should relax, avoid tension, anxiety, any discomfort should be timely to the hospital, by the doctor to clarify the diagnosis, and cooperate with the doctor to deal with the symptoms.
