Ovarian hyperstimulation syndrome. A new look at an old problem

Abstract

To analyze the management of severe ovarian hyperstimulation syndrome based on aspects of its etiology and pathogenesis a systematic review of the literature was done. An evaluation of clinical trials, meta-analysis, case-reports and reviews assessing the management of different conditions related to ovarian hyperstimulation syndrome was made using the following data sources: MEDLINE Pubmed (from 1966 to July 2018) and the Cochrane Controlled Clinical Trials Register, Embase (up to July 2018). The role of intra-abdominal hypertension in the development of the severe forms of ovarian hyperstimulation syndrome and its complicated outcomes was assessed. The pathophysiology and clinic of intra-abdominal hypertension syndrome are almost identical to moderate and severe forms of ovarian hyperstimulation syndrome and associated organ dysfunction. The classic triad (respiratory disorders, reduction in venous return, and restriction of perfusion in internal organs) is present in severe ovarian hyperstimulation syndrome as well as in intra-abdominal hypertension syndrome. This review provides recommendations for the management of ovarian hyperstimulation syndrome and insight into the different medical complaints of this syndrome. The principles of therapy for intra-abdominal hypertension syndrome might be considered in the treatment of severe forms of ovarian hyperstimulation syndrome.
