[Ovarian overstimulation syndrome: problem of intensive care].

Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic complication, the basis for which is a hyperergic uncontrolled ovarian response to gonadotropins in the ovulation stimulation cycles and assisted procreation programs. The clinical picture of OHSS is characterized by a broad spectrum of clinical and laboratory manifestations: increased vascular permeability resulting in the excess release of liquid into the third space and its storage with the development of hypovolemia, hemoconcentration, oliguria, hypoproteinemia, electrolyte imbalance, polyserositis; in severe cases, acute renal failure, thromboembolic events, and adult respiratory distress syndrome develop. The goal of treatment is to prevent the development of multiply organ dysfunctions.
