In most cases, mild uterine adhesions do not cause fetal arrest, while moderate and severe uterine adhesions can cause fetal arrest at 7-9 weeks of pregnancy. Uterine adhesions are usually caused by damage to the lining of the uterus due to a woman’s previous curettage or repeated multiple abortions. When a woman with uterine adhesions becomes pregnant, the gestational week in which fetal arrest often occurs is between 7-9 weeks of pregnancy due to abnormal implantation of the embryo resulting in too shallow implantation. At this stage, it is recommended that HCG, progesterone, estradiol, and pelvic 3D ultrasound be performed, which usually reveals a tendency toward embryonic arrest, and oral dextroprogesterone should be taken as prescribed by the doctor to preserve the fetus in a timely manner. In the presence of uterine adhesions, there will be some inflammatory factors in the endometrium, which will cause harm to the embryo, and need to be treated with medication, which can be applied to immune preparations or inhibitors of tumor necrosis factor. Uterine cavity adhesion causes embryonic sterilizations during pregnancy, the pregnancy should be terminated as soon as possible, you can choose drug abortion or artificial abortion. After medication abortion, it is necessary to pay attention to whether the embryo is delivered intact or not, and if there is any residue, it is necessary to do removal surgery. Some patients with uterine adhesions will go to full-term labor, and after delivery, it is necessary to pay attention to whether there are placental adhesions and placenta implantation. Often a severe placenta implantation may cause postpartum hemorrhage, be prepared to rescue postpartum hemorrhage.
