Abstract
- The ovarian hyperstimulation syndrome (OHSS) is a rare but serious complication of ovulation induction therapy with gonadotropin. The pathogenesis of OHSS is unclear, but the proposed mechanisms are the production of vasoactive substances that increase local capillary permeability resulting in shifting of fluid from the intravascular space to the third space. The clinical manifestations varies from ascites, hypovolemia, oliguria, hemoconcentration, thromboembolism, and even death. We have experienced a case of severe OHSS with severe ascites, pleural effusion and bilateral enlarged ovaries associated with spontaneous pregnancy without any ovarian stimulation for ovulation induction.
