A little streak of blood flow signal is usually not serious. If there is a little streak of blood flow signal in the myometrium, you may have fibroids or adenomyosis, which cause local blood vessel changes. After diagnosis, you should regulate your diet, pay attention to your emotions, stay stable and have regular review. If such a sign is present inside the uterine cavity, it may be endometrial hyperplasia, which can lead to adhesions in the uterine cavity as well as in the cervical area. If the abortion is incomplete and there is residual fetal sac tissue left in the uterine cavity, there may also be signs of blood flow in the form of dots and streaks during the examination, which should be diagnosed promptly and treated with medication to activate blood circulation and remove blood stasis, and if necessary, a curettage to completely remove the residual tissue from the uterine cavity. If abnormal masses with blurred edges are found during ovarian examinations, and if there is a dotted blood flow signal inside the mass, it may be cancerous.
