Uterine strip blood flow signal after medical abortion indicates that there is active residual tissue inside the uterus, which does not indicate whether the embryo is alive or not. If the uterine blood flow signal is accompanied by the fetal heart still visible in the uterus after medical abortion, it means that the embryo is alive and the medical abortion has failed. If there is only a blood flow signal without a gestational sac, there may be active residual tissue in the uterus, and the active residual tissue may continue to increase in size. In this case, we need to measure the size of the residual material, assess the level of HCG, and make judgment based on the comprehensive situation, and then further treatment through conservative treatment or surgical removal of the uterus. If the abortion fails, then you need to have another abortion or abortion, if only for the uterine cavity residue, residue is small and HCG is not high, you can take drugs to promote blood circulation and eliminate blood stasis, such as motherwort granules, new biochemical granules. HCG is relatively high and the residue is large, generally have to clear the uterus to deal with can be clean. The uterine strip blood flow signal after medical abortion can not prove whether the embryo is alive or not, and when abnormalities are found, it is necessary to consult a doctor in time for further treatment.
