The placenta covers the scar, which is generally called a scarred uterus, and refers to the uterine scar left after surgical treatment. It often occurs during caesarean section or abortion. When a woman becomes pregnant again, the scarred uterus poses a greater threat to her health and is prone to rupture. Once ruptured, it will seriously threaten the life and health of the pregnant woman and fetus. How to avoid uterine surgery trauma resulting in a scarred uterus? 1. Advocate natural childbirth. Establish the correct concept and confidence in natural childbirth, eat a balanced diet, exercise appropriately, control weight gain during pregnancy and fetal weight; reduce stimulation to the fetus, reduce the chances of fetal umbilical cord entanglement, umbilical cord torsion, umbilical cord knotting, etc., and minimize the factors that require cesarean section. 2. Be cautious when undergoing uterine myoma removal surgery before pregnancy. Uterine fibroids are generally benign tumors that grow slowly. If there are no medical indications, no surgery is required and long-term follow-up observation is sufficient. Precautions for pregnancy again with scarred uterus 1. After a cesarean section or uterine injury, you need to wait two years before getting pregnant. In layman's terms, after a two-year interval, the scar healed will be stronger and more secure, reducing the risk of uterine rupture. 2. Reduce factors that cause uterine overdistension. Pay attention to controlling the weight of the fetus and monitoring blood sugar levels to avoid excessive amniotic fluid due to high blood sugar. 3. In the middle and late stages of pregnancy, if you experience lower abdominal pain or sudden severe abdominal pain, go to the hospital as soon as possible. Scarred uterus childbirth problems 1. Scarred uterus after cesarean section. If the previous cesarean section was a lower uterine segment cesarean section, the birth canal is normal, the fetus is not large, and the fetal position is normal, there is a chance for trial delivery. However, because uterine rupture endangers the lives of mother and child and has serious consequences, for a long time, most people have followed the principle of "one cesarean section, every cesarean section". If the pregnant woman and her family wish to have a natural childbirth, they should first fully understand the risks of natural childbirth. The doctor will conduct a comprehensive analysis based on factors such as the interval between the previous operation and the current pregnancy, fetal size, fetal position, fetal engagement in the pelvis, thickness of the lower uterine segment, etc. During the delivery, the doctor and midwife will closely observe the progress of the delivery. If any abnormality is found, an emergency cesarean section will be performed. If there are no good conditions for trial delivery, the indications for cesarean section need to be relaxed. 2. The scar uterus after uterine fibroid removal surgery depends on the size and location of the uterine fibroids. If the uterine fibroids are small, located under the serosa or in the lower segment of the uterus, there is a chance for trial labor; if the fibroids are large, located between the muscle walls or in the body of the uterus, trial labor cannot be performed. A scarred uterus may develop a scar pregnancy, where the fertilized egg implants in the scar and the placenta covers the scar. However, the scar tissue has poor blood supply, so the placenta grows into the uterine muscle layer, forming placenta implantation. Some placental implants even penetrate the bladder. It is easy to have heavy bleeding during artificial abortion in scar area, and sometimes it is difficult to stop the bleeding and requires laparotomy. Placenta implantation may cause heavy bleeding during delivery, and hysterectomy is very risky. |
