Anterior placenta is mostly caused by the implantation of the pregnant egg in an abnormal position in the uterine cavity due to abortion, curettage, intrauterine infection, uterine malformation, uterine surgical scar, multiple pregnancy, etc. Due to the thin endometrium and myometrium of the lower uterus and cervical area, the placenta tends to extend deeper into the endometrium and myometrium, reaching the myometrium and combining with placental implantation. Placenta implantation does not necessarily mean placenta praevia. Under normal circumstances, the placenta has some small capillaries that penetrate deep into the endometrium and do not reach the myometrium, so the placenta will automatically fall off the uterus after a contraction and delivery of the fetus. If the placenta grows into the myometrium, it will not be able to fall off during contractions. Usually there is total implantation of the placenta, or partial implantation, and after there is a contraction, the unimplanted part comes off from the uterine wall, and the implanted part cannot come off, resulting in the uterus not being able to contract and bleeding. If the placenta is forcibly detached it will result in the placental tissue remaining in the myometrium, and the uterus will also not contract and end in hemorrhage. Anterior placenta combined with placental implantation is prone to bleeding, shock and hysterectomy are common and the consequences are often severe. Anterior placenta often occurs with bleeding during pregnancy, more or less, sooner or later, prone to anemia and infection. If placenta praevia consistently does not bleed, it is a strong sign of placental implantation and should be noticed. Different hospitals and different doctors have different ways to deal with different cases. Doctors and patients should trust each other, only if doctors and patients and their families understand and support each other can they have the best outcome, sometimes cutting the uterus to save life is unavoidable. Placenta implantation and placenta praevia are very serious complications with rapid and heavy bleeding, which is very dangerous. Once the bleeding stops, the only way to stop it is to cut the uterus, which is life-threatening if the blood does not clot. Placenta praevia and placenta implantation can be diagnosed prenatally. Placenta praevia is easy to diagnose, while placenta implantation requires the high technical skills of an experienced doctor and the quality of ultrasound machines that may detect placenta implantation.
