Patients:
A 29-year-old woman with severe OHSS after fresh embryo transfer after controlled ovarian hyperstimulation requiring intervention until 21 weeks' gestation in a singleton pregnancy.
Interventions:
Thorough evaluation of an unusual case of severe OHSS and medical/procedural management of its sequelae in the setting of ongoing pregnancy.
Main Outcome Measuress:
The clinical development of severe OHSS during pregnancy and its effect on pregnancy outcomes.
Results:
