If the residual tissue is larger than 1 cm after a medical abortion, it is recommended to perform an evacuation. If the residual tissue is relatively small but there is a lot of vaginal bleeding, it is necessary to actively perform a curettage procedure, otherwise there is a risk of excessive bleeding that may lead to hemorrhagic shock. If there is residual tissue in the uterus when you go to the hospital for a review on the 7th or 10th day after a medical abortion, a comprehensive analysis should be made in conjunction with the clinical history before making a decision on whether or not to remove the uterus as soon as possible. In addition, if the amount of vaginal bleeding is greater than the amount of menstruation, or if there is pain in the lower abdomen or odor in the discharge after the medical abortion, you should go to the hospital for follow-up and treatment in time.
