ABSTRACT
ABSTRACT Ovarian Hyperstimulation Syndrome (OHSS) is uncommon among oocyte donors during in vitro fertilization (IVF) procedure and is rarely associated with death. We report a case of a 23-year-old oocyte donor who suddenly died on the operation table during oocyte retrieval. She had no risk factors in her menstrual history, laboratory, or clinical parameters. The antagonist cycle, triggered with the GnRH agonist protocol, was carried out. The cause of death at autopsy was attributed to respiratory failure due to acute massive pulmonary edema, which developed due to the complication of OHSS. Only a few autopsy cases associated with OHSS have been published, but, as far as we know, no clinical or autopsy cases of sudden death caused by OHSS have been reported.
