The influence of placenta inferior margin completely covering cervical internal orifice

If the placenta completely covers the internal opening of the cervix, it should be decided according to the month of pregnancy. If this phenomenon is shown within 3-6 months of pregnancy, it is possible that the placenta can return to its normal position during pregnancy, especially the placenta on the anterior wall. The possibility of returning to its normal position is still relatively large. If it is more than 7 months pregnant, when B-ultrasound is done, the placenta still completely covers the internal opening of the cervix. This is placenta previa. Placenta previa has a greater impact on the fetus. It may show massive bleeding, premature delivery, and vaginal delivery. Surgery is necessary. When surgery is performed, because the placenta is in the lower uterine segment, this place shrinks poorly, and it may also cause massive bleeding. Therefore, in the late stages of pregnancy, if placenta previa is present, it is necessary to go to the hospital as soon as possible to prevent danger.
