[Contribution of Doppler color ultrasonography to the screening and surveillance of ovarian hyperstimulation syndrome].
Color and power Doppler producing ovarian vascular mapping allows to realize a new functional approach of ovarian hyperstimulation syndrome (OHS); local vascular factors (ovarian angiogenesis, increase in cappillary permeability) released by hCG injection (LH effect) have in fact an important part in this syndrome. Vaginal Doppler sonography allows: -before induction, to predict potential risk of hyperstimulation: polycystic ovaries, spontaneous stromal hypervascularization; -in monitoring of ovulation stimulation, to reduce risk of multiple pregnancy and to detect early hyperstimulation, decision of hCG injection depends on number of follicles able to be fertilized (> 15 mm) and luteinized (> 10 mm); -to assess severity of OHS and search complications: ascites, hydrothorax, ovarian torsion and deep venous thrombosis. So OHS prevention imposes a monitoring by Doppler sonography and estradiol assay of all cycles induced by gonadotropins.
