[Arterial thrombosis in ovarian hyperstimulation syndrome]

Ovarian hyperstimulation syndrome is an iatrogenic complication of controlled ovarian hyperstimulation. Its features are excessive growth of the ovaries and leakage of fluid from the intravascular space with ascites, hypovolemia and electrolyte imbalance, inducing a state of hypercoagulability, which can cause arterial or venous thrombosis. Thromboembolic events are the less common complications but they are the most serious. We communicate the case of a 30 years old woman with history of primary infertility; she was in treatment with controlled ovarian hyperstimulation. The patient developed ovarian hyperstimulation syndrome and arterial thrombosis in the right femoral artery.
