Under normal circumstances, the patient should not bleed more vaginally after having an angiogram. The bleeding is slightly more on the day of the angiogram, and then gradually decreases after the angiogram is done, so there should not be an increase in bleeding on the third day. If the patient’s bleeding increases on the third day after the imaging, there are several possibilities to consider: First, the patient chose the wrong time to have the imaging. Under normal circumstances, women should have the imaging done within 3-7 days after menstruation. At this time, the patient’s uterine lining is relatively thin, and there is less bleeding after the imaging. If the patient chooses an inappropriate time for the imaging and the endometrium is very thick, the patient will have more vaginal bleeding after the imaging. Second, consider that after the patient has done the contrast, the combined uterine cavity infection, resulting in local congestion and edema of the endometrium, leading to increased bleeding. Thirdly, it is considered that the patients themselves have tumor lesions of the cervix and uterus, which leads to increased bleeding after the imaging.
