Ectopic pregnancy is the result of a flaw in reproductive physiology that allows the conceptus to implant and mature outside the endometrial cavity, which ultimately ends in the death of the fetus. It is basically an extrauterine pregnancy, the vast majority in the Fallopian tubes. Ectopic means 'misplaced'. The fallopian tubes are not designed to hold a growing embryo; thus, the fertilized egg in a tubal pregnancy cannot develop properly. When a fetus does develop, it is non-viable for life. The diagnosis of ectopic pregnancy is based upon a combination of measurement of the serum quantitative human chorionic gonadotropin (beta-hCG, indicating there is a pregnancy) and findings on transvaginal ultrasonography (determining the location). Visualization of an intrauterine sac, with or without fetal cardiac activity, is often adequate to exclude ectopic pregnancy. It may be unruptured or ruptured at the time of presentation to medical care. Tubal rupture (or rupture of other structures in which an ectopic pregnancy is implanted) can result in life-threatening hemorrhage. Any symptoms suggestive of rupture should be noted. These include severe or persistent abdominal pain or symptoms suggestive of ongoing blood loss (eg, feeling faint or loss of consciousness). The fetus was removed and the placental site was found to be adjacent to, and involving, the left fallopian tube.
