Aim: Ovarian torsion (OT) is one of the common gynecologic emergencies in reproductive age women. In our study, it is aimed to make a retrospective evaluation of OT cases developed after controlled ovarian stimulation (COH) for in vitro fertilization (IVF) treatment.
Material and Method:This retrospective study was carried out in an IVF clinic between January 2015-December 2020 . Ten cases who definitely diagnosed as OT were included in this study. The medical records of these patients were examined. Data were analyzed according to demographic, clinicopathological, and sonographic findings.Results: Ten of 5186 IVF patients developed OT (10/5186; 0.19%) and all OT cases were PCOS. The mean age of OT patients was 27.3±4.1years and the mean body mass index (BMI) was 23.5±6.2 kg/m2 respectively. The mean number of retrieved oocytes was 21.46±4.12. The average diameter of the twisted ovaries of patients was 121.4±56.1 mm. Laparoscopy was performed in all OT patients for detorsion of the ovaries. It was found that OT occurred more frequently on the right side (8/10; 80%).
Conclusion:OT is more common in cases with polycystic ovary syndrome (PCOS). The risk of OT is reduced by decreasing gonadotropin dosage as well as retrieved number of oocyte. Also, prefering frozen-thawed embryo transfer can decrease OT risk in PCOS patients.
