[Some aspects of ovarian hyperstimulation syndrome].

Ovarian hyperstimulationsyndrome (OHSS) is a serious and potentially life-threatening complication of ovarian stimulation. The clinical picture of severe OHSS, includes ovarian enlargement, ascites, pleural effusion, hypercoagulation and electrolyte disorders. In this study we describe some factors which are linked with pathogenesis of OHSS. We had a case of moderate OHSS with a twin pregnancy after IVF-ET. In this case, because of abdominal pain and discomfort from the ascites, we perform abdominal paracentesis without termination of pregnancy.
