Management of Ovarian Torsion
The standard management of ovarian torsion is immediate surgical intervention with laparoscopic detorsion to preserve ovarian function, regardless of the macroscopic appearance of the ovary. 1
Clinical Presentation and Diagnosis
- Ovarian torsion typically presents as severe, constant pain that may fluctuate in intensity but rarely resolves completely without intervention 1, 2
- Common associated symptoms include nausea and vomiting (present in approximately 70% of cases) 3
- Ovarian torsion can mimic other conditions such as appendicitis, renal colic, or urinary tract infection, which can lead to diagnostic delays 1, 2
Diagnostic Imaging
Ultrasound is the first-line imaging modality with key findings including: 1, 2
- Unilaterally enlarged ovary (>4 cm or volume >20 cm³)
- Peripheral follicles (found in up to 74% of cases)
- Abnormal or absent venous flow (100% sensitivity, 97% specificity)
- Whirlpool sign (90% sensitivity in confirmed cases)
Important diagnostic considerations: 1, 2
- Normal arterial blood flow does not rule out ovarian torsion, as torsion can be intermittent or partial
- Combined transabdominal and transvaginal ultrasound provides the most comprehensive assessment
- When ultrasound findings are inconclusive but clinical suspicion remains high, MRI (80-85% sensitivity) or CT may be utilized
Surgical Management Algorithm
Immediate surgical intervention is indicated once ovarian torsion is suspected 1, 4
- Laparoscopy is the preferred approach for both diagnosis and treatment
Perform detorsion of the ovary regardless of its appearance 1, 4
- Even black-bluish appearing ovaries can recover after detorsion
- Preservation of the ovary should be attempted in all premenopausal women
Address underlying pathology 4
- If an ovarian cyst or mass is present, perform cystectomy after detorsion
- Consider oophoropexy to prevent recurrence, especially in cases with predisposing factors
Consider oophorectomy only in specific circumstances 1
- Definitive necrosis with no signs of recovery after detorsion
- Large malignant masses
- Postmenopausal women
Special Considerations
- Timing is critical: Early intervention is essential to preserve ovarian function and minimize morbidity 5, 6
- Fertility preservation: Conservative management with detorsion should be the standard approach in young women to preserve hormonal function and fertility 4
- Recurrence prevention: Oophoropexy to the pelvic sidewall or utero-ovarian ligament may be considered to prevent recurrence in high-risk cases 4
- Postoperative monitoring: Follow-up ultrasound is recommended to confirm normalization of ovarian size and morphology 4
Common Pitfalls to Avoid
- Diagnostic delay: Do not rule out ovarian torsion based on normal Doppler flow studies, as intermittent or partial torsion may still be present 1, 2
- Surgical overtreatment: Avoid unnecessary oophorectomy in young women, as even severely ischemic ovaries can recover after detorsion 4
- Incomplete evaluation: Always consider ovarian torsion in the differential diagnosis of acute abdominal pain in females of all ages 3, 7
- Misdiagnosis: Be aware that ovarian torsion can mimic other conditions such as appendicitis, renal colic, or urinary tract infection 1, 2
