[Acute pleurisy secondary to ovarian hyperstimulation after in vitro fertilization].

Pleurisies due to the syndrome of ovarian hyperstimulation typically accompany ascites and in their most severe form are associated with haemoconcentration, hypovolaemia and thromboembolic phenomena. It is not unusual in this context for pleural effusions to be isolated. They may occur during treatment for sterility by inducing ovulation, they are exudates and predominantly right sided. The pathophysiology is not clear and results in vascular hyperpermeability. Currently, no treatment aimed at the aetiology has proven its own efficacy. Spontaneous regression of the effusion is the rule but in severe forms, where the prognosis is uncertain, correction of hypovolaemia is a priority.
