Ischemic events are infrequent in patients with ovarian hyperstimulation syndrome.

BACKGROUND

Case reports describe arterial thrombosis including ischemic stroke associated with severe ovarian hyperstimulation syndrome (OHSS), but the prevalence of major ischemic events during or shortly after OHSS is unknown.

METHODS

Using publicly available administrative datasets in the United States between 2015 and 2020, we conducted two separate cross-sectional studies of patients with OHSS. We included all patients with OHSS. Our study outcome was any hospitalization for acute ischemic stroke, acute myocardial infarction, cerebral venous sinus thrombosis, pulmonary embolism, or acute deep venous thrombosis during the index hospitalization or within 90 days of OHSS diagnosis.

RESULTS AND

CONCLUSIONS

We found very few major ischemic events in patients with OHSS.
