Borderline placenta previa is a condition in which the placenta is attached to the lower part of the uterus and the lower edge of the placenta reaches the endocervical opening but does not go beyond it. The need for a cesarean section needs to be decided after a comprehensive assessment by the doctor, depending on whether there is any vaginal bleeding, without which a cesarean at 38-39 weeks is preferable.
Borderline placenta previa will have recurrent vaginal bleeding, and fetal uterine infection and fetal dysplasia may occur. Cesarean section can be chosen to terminate the pregnancy. If there is no vaginal bleeding as well as other obstetric abnormalities, cesarean section can be maintained until 38-39 weeks. If there is repeated vaginal bleeding or obstetric abnormalities, cesarean section should be performed immediately to terminate the pregnancy.
The timing of termination of pregnancy for borderline placenta previa depends on the circumstances. If there is recurrent vaginal bleeding or intrauterine hypoxia or fetal dysplasia, cesarean section should be performed as soon as possible to terminate the pregnancy.
