Ectopic pregnancy: a review.

Department of Radiology, Beth Israel Deaconess Medical Center, Boston, MA 02215, USA.

Ectopic pregnancy is a major clinical problem, occurring in 75,000 cases per year in the United States. With in vitro fertilization, embryo transfer, microsurgical techniques, and better early diagnosis, the rates of ectopic pregnancies have increased. Transvaginal sonography along with beta-human chorionic gonadotrophin monitoring are the standards for evaluation of suspected ectopic pregnancy. When ectopic pregnancy is present, transvaginal sonography most often demonstrates an adnexal finding directly related to the extra-uterine gestation itself, a hematoma caused by it, or both. Although tubal location is most common, it is important to recognize unusual locations of ectopic pregnancy such as isthmic, cervical, ovarian, and abdominal. Ultrasound is the mainstay of diagnosis, but magnetic resonance imaging can be helpful in unusual or complicated cases. Current therapeutic options for an ectopic pregnancy are expectant management, systemic methotrexate injections, sonographically guided minimal invasive treatment, and surgery. This review encompasses diagnosis, treatment, and management of ectopic pregnancy.
