Study Objectives: To investigate the phenomenon of recurrent adnexal torsion during the same pregnancy, describe its risk factors, and suggest possible management of this entity. Design: Retrospective case-control study (Canadian Task Force classification II-3). Setting: Gynecologic endoscopy unit in a university hospital. Patients and interventions: Pregnant women with surgically proved adnexal torsion were retrospectively identified from 1993 to 2007. Details of clinical presentation, method of conception, preoperative ultrasound findings, and operative findings were analyzed. Intervention: Comparison of characteristics of patients with recurrent episodes of adnexal torsion during the same pregnancy vs a single episode of torsion. Measurements and Main Results: Thirty-three pregnant women with 38 episodes of adnexal torsion were included in the study. Seventeen pregnancies (51.5%) were spontaneously conceived. Twenty-eight women had a single episode of torsion, and 5 women (15.1%) had recurrent episodes of torsion during the same pregnancy. No significant differences were found between the 2 groups in age, method of conception, and gestational age at time of torsion. However, ultrasound studies demonstrated that multicystic ovaries were significantly more common in women with recurrent torsion compared with women with a single episode of torsion (80% vs 25%; p = .02). The interval between the first and second episodes of torsion ranged from 1 to 4 weeks. Conclusion: Pregnant women are at risk for recurrent torsion, especially when the ovaries are enlarged and ultrasound studies demonstrate multiple cysts. Cyst aspiration may prevent recurrent torsion during the same pregnancy.
