Prevention of Ovarian Hyperstimulation Syndrome

چکیده
Ovarian hyperstimulation syndrome (OHSS) is rare but most serious complication of ovarian stimulation. Symptoms are mainly related to increased capillary permeability leading to extravasation of fluid into extravascular compartment. Disease pathophysiology is linked to hCG (human chorionic gonadotropin) which acts through angiogenic molecule vascular endothelial growth factor (VEGF). There is recent development of interest in use of dopamine agonist for prevention of OHSS, which act through blockage of VEGF by preventing phosphorylation of VEGF-2 receptor. Once there is full blown OHSS, treatment is mainly symptomatic. By careful selection of stimulation protocols & recognisition of high risk cases at an early stage, early OHSS can be prevented to a major extent. Use of GnRH antagonist protocols & GnRH agonist as final trigger leads to marked reduction in incidence of OHSS without compromising pregnancy rates. So, prevention has been mainstay of treatment for this rare but lifethreatening iatrogenic complication of ovarian stimulation.

Cabergoline versus Coasting in the Prevention of Ovarian Hyperstimulation Syndrome and Assisted Reproductive Technologies Outcome in High Risk Patients
Background Coasting is the most common method used in the prevention of ovarian hyperstimulation syndrome (OHSS) acting through vascular endothelial growth factor (VEGF) reduction. However, the pregnancy rate is reported to fall with coasting when it takes more than three days. Recently lowdose cabergoline, a selective D2 dopamine receptor agonist has been proven to selectively reduce vascular ...

Ovarian Hyperstimulation Syndrome (OHSS) is a rare complication of super ovulation and in vitro fertilization (IVF). Although our understanding of its pathophysiology is incomplete, induction of development of multiple follicles, perturbation of the renin angiotensin system and exposure to luteinizing hormone (LH) or human chorionic gonadotropin (hCG) are essential contributing factors to its d...

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...
