ECTOPIC PREGNANCY
Ectopic pregnancy happens when the fertilized ovum implants outside the endometrial lining of the uterus.
Accurate early diagnosis is life-saving, reduces invasive diagnostic procedures & allows conservative treatment that can preserve fertility.
Ectopic pregnancy must be excluded in women of reproductive age w/ a positive pregnancy test, abdominal pain & vaginal bleeding.
Ruptured ectopic pregnancy remains to be the leading cause of maternal mortality in the first trimester.

Definition

  • Any pregnancy in which the blastocyst implants outside the endometrial lining of the uterine cavity
    • 90% are located in the fallopian tube while the rest are extratubal (eg abdominal, cervical, heterotopic, interstitial, ovarian, cornual or cesarean scar pregnancies)

Accurate early diagnosis is life-saving, reduces invasive diagnostic procedures and allows conservative treatment that can preserve fertility

  • Ectopic pregnancy must be excluded in women of reproductive age with a positive pregnancy test, abdominal pain and vaginal bleeding
  • Ruptured ectopic pregnancy remains to be the leading cause of maternal mortality in the 1st trimester
