This article reports a case of spontaneous ovarian hyperstimulation syndrome (OHSS) following a thawed embryo transfer cycle. OHSS, a potentially life-threatening condition, is an iatrogenic complication of controlled ovarian stimulation; therefore, it is very important to prevent and treat OHSS during treatment with ovulation-inducing agents. Despite our efforts to prevent OHSS, in this case, ...

Changes in CA602 and CA546, two carbohydrate-related antigens newly established in our institute, were evaluated during the course of in-vitro fertilization and embryo transfer. The concentration of CA602, an antigen with characteristics similar to those of CA125, did not change substantially until embryo transfer. In patients with clinical evidence of ovarian hyperstimulation syndrome (OHSS), ...

Severe ovarian hyperstimulation syndrome (OHSS) is a rare but potentially fatal condition associated with conventional IVF treatment. It is found predominantly in women with polycystic ovaries who have an exaggerated response to exogenous FSH, leading to a large number of follicles and an overproduction of vascular endothelial growth factor with resultant excessive increases in vascular permeab...

OBJECTIVE To compare pregnancy rates with fresh and frozen embryo transfer in patients admitted to Royal Jubilee Maternity Service (RJMS), Belfast between January 1st 2004 and December 31st 2005 with ovarian hyperstimulation syndrome (OHSS). METHOD A retrospective analysis of all ART cycles (2,283) carried out in RJMS between January 1st 2004 and December 31st 2005 and of all patients admitte...

OBJECTIVE To investigate the oocyte quality in patients with severe ovarian hyperstimulation syndrome (OHSS). DESIGN Self-controlled clinical study. SETTING University teaching hospital. PATIENT(S) Twenty-two patients from our assisted reproductive technology (ART) program who developed severe OHSS during their first controlled ovarian hyperstimulation for IVF or intracytoplasmic sperm in...

BACKGROUND Ovarian hyperstimulation syndrome (OHSS) is a potentially life-threatening condition associated with increased vascular permeability. The vascular endothelial growth factor (VEGF) system and its receptors have been identified as the main angiogenic factors responsible for increased capillary permeability and are therefore discussed as crucial for the occurrence of OHSS. Recently, a n...

OBJECTIVE To describe our experience with aggressive outpatient transvaginal paracentesis to manage ovarian hyperstimulation syndrome (OHSS). DESIGN Retrospective case series. SETTING Private, academically affiliated IVF center. PATIENT(S) Women undergoing assisted reproductive technologies (ART) and having a diagnosis of OHSS. INTERVENTION(S) Management of OHSS with hospitalization or ...

BACKGROUND Ovarian hyperstimulation syndrome (OHSS), is characterized by marked ovarian enlargement and acute third space fluid sequestration that almost always develops after hCG administration or in early pregnancy. OHSS is similar to vascular leak syndrome (VLS), which may be attributable to the massive increase in systemic inflammatory cytokines. In the present pilot exploratory case series...

Type 2 receptors for vascular endothelial growth factor are believed to be involved in the pathophysiology of ovarian hyperstimulation syndrome (OHSS). The objective of this study was to examine the preventive effects of cabergoline on OHSS and its complications. The study is a non randomized clinical trial conducted in 2006-2008 on 75 patients, which were at risk of OHSS and underwent assisted...

The aim of this review was to summarize previously published classifications for ovarian hyperstimulation syndrome (OHSS), as well as to analyse the available methods for preventing OHSS. Withholding hCG and cycle cancellation--once the main methods of preventing OHSS--are now seldom used. There is a growing body of evidence to support the use of coasting to prevent OHSS, without cycle cancella...
