ABSTRACT
Ovarian hyperstimulation syndrome (OHSS) is a potentially fatal iatrogenic complication of the luteal phase in ovulation stimulation. This syn drome is characterized by an increased size of the ovaries due to multiple cysts, and by an increase in the vascular permeability causing ascites, pleural effusion and sometimes even pericardial effusion. Severe forms are also accompanied by electrolyte disturbances and cardiopulmonary, hepatic, renal and hemody namic disturbances associated with increased thromboembolic risk.
