Objective To investigate the clinical characteristics , diagnosis and operation effect of spontaneous ovarian torsion .Methods The clinical data of 16 cases of spontaneous ovarian torsion were retrospectively analyzed .Results There were 5 patients undergoing unilateral salpingo oophorectomy and 2 undergoing oophorectomy .Nine cases underwent ovarian reduction , including 5 cases with ovary arteriovenous high ligation before restoration and 1 case with ovary suspension after restoration .The ipsilateral ovary of patients with simply reset had normal ovarian blood flow 15 days after operation.It had dominant follicle after 1-3 months, and had normal serum level of estradiol and progesterone .Ipsilateral ovary of patients with ligation of ovarian artery and vein before reset had little ovarian blood flow 1 week after the operation ,and 1 month later the blood flow was almost normal .They had dominant follicle after 2-3 months, and had normal serum levels of estradiol and progesterone .Three cases had good outcomes of pregnancy .Conclusion Early diagnosis and treatment is important to the cure of disease and the preservation of ovarian function .It is simple, safe and effective to ligate the ovary artery and vein before restoration , and it is worthy of clinical application .%目的：探讨自发性卵巢囊肿扭转的临床特点、诊断及手术治疗效果。方法回顾性分析16例自发性卵巢扭转患者的临床资料。结果5例患者行患侧附件切除术，2例行卵巢切除术。9例行卵巢复位术，复位术中5例复位前先高位结扎卵巢动静脉，1例复位术后行卵巢悬吊术。单纯复位者术后15天患侧血流接近正常，术后1～3个月内患侧卵巢可见优势卵泡，血雌、孕激素水平恢复正常。复位前结扎卵巢动静脉者术后1周患侧卵巢均有少量血流，术后1个月血流接近正常，术后2～3个月患侧卵巢可见优势卵泡，血雌、孕激素水平恢复正常。3例合并妊娠者结局良好。结论早发现、早诊断、早治疗是治愈本病，保留卵巢功能的关键，采用先高位结扎卵巢动静脉再将扭转的卵巢复位的方法简单易行、安全有效，值得临床推广。
