Secondary uterine clearance may lead to uterine adhesions. It is not always possible to cause uterine adhesions when performing a uterine clearance; if excessive scraping causes damage to the basal layer of the endometrium, it may increase the chances of uterine adhesions. Avoid uterine adhesions by using contraception first. In case of embryonic arrest or inevitable miscarriage, reducing the number of surgical removal operations is also a preventive measure to avoid uterine adhesions. Carefulness and gentleness when the doctor performs the operation are also important points to avoid the occurrence of uterine adhesions. If the menstrual flow is significantly reduced after the removal operation, the possibility of uterine adhesion should be considered and the cause should be clarified in time.
