Clinical analysis of ovarian torsion in pregnant women after in vitro fertilization and embryo transfer

Abstract

Objective To analyze the clinical characteristics, diagnosis, treatment, and outcomes of ovarian torsion in pregnant women after in vitro fertilization and embryo transfer (IVF-ET). Methods The clinical data of pregnant women with ovarian torsion after IVF-ET in our hospital from January 2014 to December 2016 was retrospectively analyzed. Data collecting included onset / treatment time of ovarian torsion, ovary volume, torsion degree, gestational weeks, and pregnancy outcomes. Results 4 cases were collected, 3 cased were intervened by laparotomy and 1 case was treated with ipsilateral salpingectomy. 3 cases continued the pregnancy after intervention; 1 case was sent to hospital at 30 hours after the onset of ovarian torsion caused by embryonic diapause. Conclusions Ovarian torsion is an emergency complication in pregnant women after IVF-ET. Timely surgery intervention can benefit the pregnancy outcomes.
