Alternative strategies for the management of ovarian hyperstimulation syndrome, the role of intra-abdominal hypertension control.

The aim of this study is to analyze the methods for reducing intra-abdominal pressure (IAP) in the management of the moderate and severe forms of ovarian hyperstimulation syndrome (OHSS). We carried out a systematic review of the literature. An evaluation of clinical trials, meta-analysis, case-reports, and reviews assessing the management of conditions associated with OHSS and intra-abdominal hypertension (IAH)/abdominal compartment syndrome (ACS) was made using the following data sources: MEDLINE Pubmed (from 1966 to July 2019) and the Cochrane Controlled Clinical Trials Register, Embase (up to July 2019). The principles of treatment of IAH syndrome can be considered in the treatment of moderate and severe forms of OHSS. Medical treatment of patients with increased IAP in OHSS should be started early to prevent further organ dysfunction and avoid a transition to a more severe stage of IAH and ACS. Some of the new, non-surgical methods, such as continuous negative extra-abdominal pressure, are a promising option in specific groups of patients with OHSS. This review provides suggestions for the management of OHSS based on the principles of therapy for IAH syndrome. Further well-designed studies are needed to confirm these initial data.
