Adnexal Torsion Associated With Recurrent Ovarian Hyperstimulation Syndrome: A Case Report

Abstract

Adnexal torsion due to hyperstimulation is one of the well-recognized serious complications of assisted reproductive techniques like in vitro fertilization (IVF). We report a case of a 35-year-old primigravida who presented to the emergency department with complaints of acute severe left iliac fossa pain and nausea. Further history revealed that the patient had previously undergone one cycle of ovulation induction and was diagnosed with ovarian hyperstimulation syndrome (OHSS). After prompt management, she reportedly underwent a cycle of IVF successfully. Her gestational age was five weeks and one day on presentation. A transabdominal ultrasound revealed bilateral enlarged ovaries with adequate blood supply and a single intrauterine gestational sac with a yolk sac.The patient was admitted as a case of recurrent OHSS for conservative management. Despite the initial improvement of symptoms with parenteral analgesia, an emergency laparoscopic surgery was done later due to worsening symptoms. Intraoperative findings were consistent with the suspected diagnosis of adnexal torsion which was managed accordingly. Postoperatively, the patient recovered without complications and was discharged two days later with a plan for outpatient follow-up.
