Laparoscopic therapy of an intact primary ovarian pregnancy with ovarian hyperstimulation syndrome: case report

A case of an intact primary ovarian pregnancy with ultrasonographic demonstration of heart motion following ovarian stimulation is presented. After preoperative ultrasonographic confirmation of an extrauterine pregnancy, proof of the ovarian localization was achieved by intra-operative ultrasonographic visualization during a diagnostic laparoscopy on post-menstrual day 48. A moderate ovarian hyperstimulation syndrome with a concomitant increase in size, vulnerability and vascularity of the ovaries presented an additional challenge for the surgical approach. However, thanks to the early diagnosis of the ectopic pregnancy localization, a laparoscopic organ-preserving removal of the intact ovarian pregnancy was successfully performed. In this way, the fertility of the patient, who had previously undergone contralateral ovariectomy, was preserved. To our knowledge, this represents the first such treatment to be reported in the medical literature. Improvements in diagnosis and therapy of ovarian pregnancy are reviewed.
