If the follow-up ultrasound after abortion suggests that the abortion is not clean, there are three main treatment methods: First, if the residual tissue in the uterus after abortion is relatively small, you can take medication, using medication that activates blood circulation and removes blood stasis to promote the discharge of residual tissue from the uterus, or take a contraction injection to promote uterine contraction to help discharge residual material. If there is not much residue in the uterus, you can help the residue to be discharged by doing uterine rejuvenation, abdominal physiotherapy, uterine massage and so on. Third, if the residue is large, it is best to perform a hysterectomy, in order to clean the uterus, it is best to clear the uterus under the guidance of ultrasound, the success rate is higher, and pay attention to the anti-infection treatment after the operation.
