Corner pregnancy refers to the development of the fertilized egg in the corner of the uterine cavity, adjacent to the opening of the fallopian tube, the embryonic tissue in the uterine cavity, intrauterine pregnancy; ectopic pregnancy, also known as ectopic pregnancy, is the fertilized egg is deposited in the uterus outside the body cavity. Ectopic pregnancy, also known as ectopic pregnancy, is a fertilized egg that is deposited outside the uterine cavity. Corner pregnancy, although intrauterine, is more serious than ectopic pregnancy. Uterine corner pregnancy is due to the fertilized egg in the corner of the uterus, where the muscle tissue is thin and rich in blood, once rupture occurs, hemorrhage, shock, life-threatening. Ectopic pregnancy weighs 95% for tubal pregnancy, pregnancy process can be manifested as miscarriage, rupture. If complete abortion, generally bleeding is not much; if incomplete abortion, can form local hematoma or pelvic blood; if rupture occurs, feasible tubectomy on the affected side; if the tubal interstitial pregnancy rupture, the situation is just like the uterine horn pregnancy, hemorrhagic shock occurs in a short period of time, endangering life. Uterine horn pregnancy is more dangerous, without rupture surgery, with the help of hysteroscopy, laparoscopy, suction or forceps, or uterine horn incision to remove the embryo, repair the uterine horn; if rupture occurs, the affected side of the uterine horn and the same side of the fallopian tube need to be removed. Once a woman of childbearing age is determined to be pregnant, she should go to the hospital in a timely manner to rule out uterine horn pregnancy and ectopic pregnancy, in order to ensure the safety of pregnancy.
