In this case, it is important to consider the possibility of uterine adhesions, especially in women who have just had an abortion, the possibility of uterine adhesions is greater. In this case, after a basic ultrasound examination, the first and foremost examination is a hysteroscopy, which can further clarify or rule out the possibility of uterine adhesions. If uterine adhesions are detected under the hysteroscopy, a hysteroscopic detachment of the uterine adhesions can be performed. After the detachment procedure, as there is still a possibility of recurrence of uterine adhesions, estrogen or IUD can be applied to reduce the possibility of recurrence of uterine adhesions thereafter.
