There was a time when the cesarean rate in China was as high as 60-70%, much higher than the WHO rate of 30%. Could it be that the Chinese people have lost the ability to give birth naturally. When so many mothers cried and cried that they did not want to try to give birth by themselves or gave up halfway and tried to ask for a cesarean section, most of them probably thought that they could only give birth once in their lives, so why should they go through such an uncertain thing, and that everything would go smoothly with a single cut. So more than a decade has passed, a large number of 30-40-year-old women’s belly left a scar of beauty. But who would have thought that with the opening of the second child, the once-in-a-lifetime birth could be twice, and when a large number of women with cosmetic scars were pregnant with a scarred uterus with two children, problems followed. Cesarean scar pregnancy – according to the general experience, if a pregnant woman wants to have this baby, she may not go to the hospital for examination until it is time to have a file, which is often already 3 months old. And who knows that this child has quietly grown into the scar of the uterus, and the term cesarean scar pregnancy was born. The child that grows into the scar will stretch the scar thinly and will penetrate the uterus, causing uterine rupture; it will grow into the uterine muscle, causing placental implantation. All kinds of problems will eventually lead to a high risk of pregnancy, resulting in a geometric increase in the occurrence of late pregnancy fatal placenta praevia placenta implantation, the obstetrics department will become a major user of blood and a serious threat to maternal life and safety. And this situation can be avoided. The incidence of cesarean scar pregnancy is not high 1/2000, but then foreign statistics, and for such a high denominator of cesarean population in China, the rate must only be higher. So is there a way for us doctors or mothers preparing for pregnancy to avoid this thing from happening? The answer is: no. So how can we minimize the possible adverse consequences of a cesarean scar pregnancy? Early diagnosis is the key, and the location of the child’s bed can be clarified at 5 weeks of pregnancy. If you have a history of cesarean delivery, be sure to alert your doctor to look at the gestational sac in relation to the scar, which can be done with a combination of transabdominal ultrasound and transvaginal ultrasound to improve accuracy. But where the gestational sac is located in the scar, you should not risk carrying it on because the chances of developing an aggressive placenta praevia at a later stage are very high. This means that for women with a history of cesarean delivery an ultrasound should be done early to determine if the pregnancy is a cesarean scar pregnancy and if found terminate the pregnancy as early as possible. The termination of a cesarean scar pregnancy is also different from that of a normal abortion because the hemostasis after abortion relies mainly on the contraction of the uterine muscles, which squeezes the uterine vessels and occludes them. In contrast, the thinning of the muscle layer at the site of the cesarean scar and the lack of pressure during contraction may result in hemorrhage during the abortion. Therefore, if the diagnosis is a cesarean scar pregnancy, the abortion must be performed in a hospital with a blood source, hemostatic measures (such as uterine artery embolization) and experience. At present, most tertiary hospitals and affiliated hospitals in Beijing are equipped with the personnel and instruments to treat cesarean scar pregnancies. All have also gained extensive clinical experience and multiple methods are basically successful in terminating pregnancy. Here we are talking about the early pregnancy period, which also refers to the situation before the formation of the placenta. More specifically, it is before the 10th week of pregnancy, when our doctors and pregnant women need to do it. It is the ideal time to diagnose and manage the pregnancy with a high success rate and a relatively low risk of hemorrhage and uterine rupture.
