ABSTRACT
A brief review of the literature on ovarian pregnancy is made. A case of on ovarian pregnancy in which a live baby was delivered abdominally is reported. Although ovarian pregnancy is one of the rarest forms of extrauterine pregnancy, its incidence is generally estimated to be between 0.7% to 1.07% of all ectopic gestations, or one ovarian pregnancy in 25,000 to 40,000 pregnancies. At Siriraj Hospital, an incidence of ovarian pregnancy is about 2.5% of all ectopic gestations, or one ovarian pregnancy in 8,100 pregnancies. Of these cases over 95% occurred before the 28th week of gestition. There were onlyu a few patients who delivered after the 28th week with a viable baby. The symptoms of ovarian pregnancy differ slightly from those of the more common forms of ectepic gestation. In case of advanced ovarian pregnancy, there may not be a profound difference from normal intrauterine pregnancy or abdominal pregnancy. Therefore it is virtually impossible to make a preoperative clinical diagnosis.
