Background
Ectopic pregnancy is also called ectopic pregnancy, which refers to the abnormal pregnancy process of nidation and development of fertilized eggs outside the uterine cavity, so that tubal pregnancy is the most common. The poor lumen patency is often caused by the inflammation of the lumen or the periphery of the fallopian tube, which hinders the normal operation of the pregnant ovum, so that the pregnant ovum stays, lands and develops in the fallopian tube, resulting in abortion or rupture of the fallopian tube in pregnancy. Before abortion or rupture, there are no obvious symptoms, and there may be symptoms of menopause, abdominal pain, and small amount of vaginal bleeding. Once ruptured, it manifests as acute and severe abdominal pain, recurrent episodes, vaginal bleeding, and even shock; and the women who are too obese can not be clearly diagnosed by multiple examinations, so that the treatment opportunity is easily delayed, and the serious threat is brought.
