Placental umbilical cord inserted from the edge of placenta 1.6 1CM?

This condition is called sail placenta, which generally leads to fetal growth restriction. If the umbilical cord attachment point is just at the lower edge of the placenta near the cervix, it can be pressed by the fetal exposure, causing fetal distress and even death. However, when its blood vessels are close to the cervix and located in front of the presentation, it will lead to fetal blood loss.
