If the abortion is not clean, the first thing to do is to review the ultrasound to see the amount and location of the residue, and then perform a curettage. After the cleanup, pay attention to the oral intake of motherwort granules to promote the recovery of the uterus, oral anti-inflammatory drugs for anti-inflammatory treatment, if necessary, you can also give intramuscular injection of contraction of the uterus to promote contraction. The ultrasound will be repeated one week after the operation to see if the uterus has been cleared. If there is still residue after the cleaning, the location is special, it may be very difficult to clear, in this case can consider doing hysteroscopic cleaning.
