Case series of primary ovarian pregnancy

Abstract

Ovarian pregnancy is a rare form of ectopic pregnancy, and is most diffi cult to diagnosis before surgery. This study was conducted as a retrospective cohort series of women presenting to Korea University Medical Center between January 2000 and July 2011 in whom a diagnosis of ovarian pregnancy was made. We had total 7 cases of ovarian pregnancies between January 2000 and July 2011 at Korea University Medical Center. The mean age of the 7 ovarian pregnancy cases was 33.0 years (range, 22 to 42 years), mean parity was 1.0 (range, 0 to 3), mean gestational age at diagnosis was 8.0 (range, 5.6 to 12.4 weeks), and mean initial beta human chorionic gonadotropin (HCG) was 1,195.49 mIU/mL (range, 200.5 to 2,098.201 mIU/mL). The beta HCG level was lower remarkably in ovarian pregnancy group than in the tubal pregnancy group, and further study may be needed to find out the correlation between beta HCG level and ovarian pregnancy.
