目的:探讨辅助生殖技术治疗时发生卵巢扭转的时机、诊断和治疗方法。方法:对郑州大学第二附属医院生殖中心收治的1例取卵前卵巢扭转的患者的临床资料进行回顾性分析并复习相关文献。结果:患者取卵前一天突然下腹痛，经阴道多普勒超声提示卵巢扭转，经阴道穿刺减压无效时及时行腹腔镜手术复位固定，保留了卵巢。结论:卵巢体积中等增大是卵巢扭转的高危因素，临床表现无特异性，诊断以阴道多普勒超声为准，及时进行腹腔镜下扭转复位并固定可避免卵巢坏死切除，并可防止术后复发，值得临床应用。“,”Objective:To explore the opportunity, diagnosis and treatment of ovarian torsion in assisted reproductive technology.Methods:The clinical data of a case of ovarian torsion before oophorectomy in the Reproductive Center of the Second Affiliated Hospital of Zhengzhou University were analyzed retrospectively and the relevant literatures were reviewed.Results:The patient had a sudden hypogastralgia on the day before oocyte retrieval, and the ovarian torsion was indicated by transvaginal Doppler ultrasound. When the transvaginal puncture decompression was ineffective, laparoscopic surgery was performed in time to restore and fix the ovary.Conclusion:The increase of ovarian volume is a high risk factor for ovarian torsion, and its clinical manifestations are nonspecific. The diagnosis is based on vaginal Doppler ultrasound. Timely reduction and fixation of the torsion under laparoscope can avoid ovarian necrosis resection and prevent postoperative recurrence, which is worthy of clinical application.
