If the patient’s blood HCG value is more than 70,000 mIU/mL, and the patient’s uterine cavity only has a gestational sac when the ultrasound is done, and there is no fetal heart and buds found, the following possibilities are mainly considered in this case: First, the patient has a situation of embryonic cessation of development, and the patient’s embryonic cessation of development, the HCG level will have a gradual decline, and the patient will be accompanied by abdominal pain and bleeding at the same time. It is necessary to continue to observe whether the patient has bleeding, abdominal pain, and whether the HCG level will continue to decline. Secondly, it is necessary to consider that the patient may have an abnormal pregnancy, such as a gravidarium or trophoblastic disease, and ultrasound shows that the gestational sac in the uterine cavity of the patient is not regular, or there is a falling snow-like shape, or there are other abnormal echoes. In this case, the patient needs to do purging surgery, after purging surgery to remove the tissue sent to the pathology examination can be clear diagnosis. Thirdly, we should consider that the patient may be intrauterine combined with extrauterine pregnancy, the patient’s intrauterine embryo is not well developed, but the extrauterine embryonic tissue is well developed, so the activity is relatively high, the patient did ultrasound, did not pay attention to the situation of the ectopic pregnancy mass, you need to carefully carry out ultrasound examination, and to observe whether the patient has abdominal pain and bleeding, and according to the dynamic observation of the situation of the appropriate treatment.
