In this case, it is important to pay close attention to the possibility of reduced menstrual flow due to the presence of uterine adhesions. This possibility is further increased, especially if there is a clean-out operation after a medical abortion. If this occurs after a medical abortion, it should be considered in conjunction with the thickness of the endometrium as indicated by ultrasound and the specific menstrual volume, and if necessary, a hysteroscopy should be performed to find out if there is a possibility of uterine adhesions. Hysteroscopy is particularly useful for women who are still fertile and have fertility requirements. If adhesions are found during the examination, it is best to break them down under the hysteroscope and give appropriate medication to further reduce the likelihood of recurrence and to observe the menstrual flow to see if the adhesions have resolved.
