ACUTE PLEURISY SECONDARY TO OVARIAN HYPER STIMULATION AFTER IN-VITRO FERTILIZATION

Pleurisies due to the syndrome of ovarian hyperstimulation typically a ccompany ascites and in their most severe form are associated with hae moconcentration, 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 cle ar and results in vascular hyperpermeability. Currently, no treatment aimed at the aetiology has proven its own efficacy. Spontaneous regres sion of the effusion is the rule but in severe forms, where the progno sis is uncertain, correction of hypovolaemia is a priority.
