Abstract

Objective: To evaluate the characteristics and treatment of ovary torsion after controlled ovarian hyperstimulation.

Methods: Between Jan.2008 and Dec.2011, 5 cases with ovary torsion who underwent ovarian hyperstimulation were retrospectively studied.

Results: Five cases presented intermittent lower abdominal from 1 to 38 days after oocyte retrieval. Enlargement of ovary and decreased or absent venous and/or arterial flow were demonstrated by Doppler sonography. Two torsions at left side, two torsions at right side, and one on bilateral side were observed. Three cases give up embryo transplantation, 2 cases were pregnant after surgical treatment. One case with partial torsion was successfully treated with simple conservative treatment. Two cases with complete torsion were performed adnexectomy by laparotomy. One case with complete torsion with early pregnancy was managed by laparoscopic adnexectomy. One case with chemical pregnancy was managed by laparoscopic detorsion for left side and excision for right side. Postoperative pathology of ovary tissue all confirmed haemorrhage and necrosis.

Conclusions: Ovary torsion might occur after controlled ovarian hyperstimulation. The early management on ovary torsion will be benefit for preserving ovarian function.
