| ［摘要］ 目的 探讨卵巢扭转的声像图特征性表现及检查技巧。方法 应用彩色多普勒超声仪对15例卵巢扭转患者进行检查，分析其二维超声征象，并应用彩色多普勒超声评估卵巢内血流情况，以判断卵巢成活与否。检查结果与手术对比。结果 15例患者患侧卵巢均表现不同程度增大，卵巢基质回声增高，回声分布不均质，其中11例卵巢外带可见“串珠状”卵泡结构，12例合并卵巢良性肿瘤病变，6例可显示血管蒂结构；12例彩色多普勒超声显示卵巢内及血管蒂无血流信号，3例卵巢内有中央静脉血流信号显示。结论 超声检查是诊断卵巢扭转的首要影像技术，并能根据卵巢扭转血管蒂及卵巢内血流情况预测卵巢功能情况，为临床诊治提供可靠依据。 |

| ［Abstract］ Objective To investigate the ultrasonic features and scan skills in the diagnosis of ovarian torsion using color Doppler ultrasound.Methods Fifteen patients with ovarian torsion were routinely detected by ultrasound system with curved transducer, endocavity transducer, and linear transducer. The sonographic findings of ovarian torsion were completely evaluated, including gray-scale ultrasound and color Doppler ultrasound. The results were compared with the operation.Results Ultrasonic features of ovarian torsion included unilateral enlarged ovary (15 cases), uniform peripheral cystic structures (11 cases), a coexistent benign mass (12 cases) with the affected ovary, and twisted vascular pedicle (6 cases). Lack of arterial or venous flow was demonstrated in 12 cases. And venous flow was demonstrated in 3 cases by color Doppler ultrasound.Conclusion Ultrasonography is the primary imaging modality for accurate evaluation of ovarian torsion. Twisted vascular pedicle and central venous flow demonstrated with color Doppler ultrasound may indicate that the ovary is viable. |
