summary

How can ectopic pregnancy be detected? In fact, when ectopic pregnancy occurs, there are many signals that women can know, such as menopause or bleeding. These are the manifestations of early ectopic pregnancy. Let's talk about whether B-ultrasound can detect ectopic pregnancy.

Can ectopic pregnancy be detected by B-ultrasound

First, because the blood in the abdominal cavity is most likely to accumulate in the uterorectal fovea, even if the amount of blood is not much, it can also be aspirated through the posterior fornix puncture. 18 long needle is used to puncture the uterorectal fovea from the posterior fornix of vagina and extract the dark red non coagulation. The positive result indicates that there is blood in the abdominal cavity

Second: in pregnancy test, syncytial cells secrete hCG when the embryo is alive or trophoblast is active. Pregnancy test can be positive. Because the hCG level in patients with ectopic pregnancy is lower than that in normal pregnancy, the positive rate of general hCG determination method is lower, and more sensitive β - hCG radioimmunoassay or monoclonal antibody enzyme labeling method should be used

Third: ultrasound diagnosis In the early stage of tubal pregnancy, the uterus is enlarged, but the uterine cavity is empty. There is a low echo area beside the uterus. This kind of image is not the acoustic characteristics of tubal pregnancy. It is necessary to exclude the possibility of early intrauterine pregnancy with pregnancy corpus luteum. It is very important to detect the gestational sac and fetal heart beat by ultrasound in the diagnosis of ectopic pregnancy. If the pregnancy is located outside the uterus, it can be diagnosed as ectopic pregnancy In utero, ectopic pregnancy can be excluded. B-ultrasound has important clinical significance in early diagnosis of interstitial pregnancy. It can show that one side of the uterine horn is protruding, and there is obvious gestational sac in the local myometrial thickening
