摘要
目的 分析三叉神经痛患者MRI表现 ,探讨MRI对三叉神经痛神经血管压迫的诊断价值。材料与方法 回顾性分析 85例三叉神经痛患者MRI表现及手术结果。结果 85例三叉神经痛患者共 170侧脑池段三叉神经MRI检查中 ,5 9侧存在三叉神经血管压迫或接触 ,可疑接触 35侧 ,其中症状侧有神经血管压迫、接触或可疑接触者为 75侧 ,经统计学分析 ,三叉神经痛患者症状有无与是否存在血管压迫或接触有显著意义 (P <0 .0 0 1) ;85例患者症状侧行手术治疗 ,术中证实有血管压迫或接触者 6 9例 ,根据手术结果 ,MRI诊断三叉神经痛神经血管压迫或接触的敏感性为 88.2 % ,特异性为 94.4% ,诊断神经血管可疑接触的特异性为76 .2 %。结论 MRI能清晰显示三叉神经脑池段与毗邻血管之间的关系 ,对三叉神经血管压迫或接触的正确诊断具有较高的特异性和敏感性 。
Objective To evaluate MR findings and diagnostic value of neurovascular compression in patients with trigeminal neuralgia.Materials and Methods MR manifestations and operative results of eightyfive patients with trigeminal neuralgia were reviewed retrospectively.Results Fiftynine sides had vascular compression or contact at MR imaging in one hundred and seventy sides of the trigeminal nerve of eightyfive patients with trigeminal neuralgia, thirtyfive sides had uncertain vascular contact. Seventyfive sides showed vascular compression, contact or uncertain contact in these eightyfive sidesrelated symptoms and signs. The difference between the symptomatic sides and asymptomatic sides was statistically significant (P<0.001). Sixtynine symptomatic patients were verified as vascular compression or contact by the operation. The sensitivity and specificity of MR diagnosis of vascular compression or contact was 88.2% and 94.4% respectively, the specificity of MR diagnosis of uncertain vascular contact was 76.2%.Conclusion MR had higher specificity and sensitivity in diagnosing neurovascular compression or contact, it played an important role in demonstrating the relationship of the cisternal portion of the fifth cranial nerve to surrounding vascular structures.
