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 ,对提供术前评估和指导治疗有极其重要的意义
Objective To analyze the MRI findings of patients with trigeminal neuralgia and to explore the value of MRI in the diagnosis of neurovascular compression of trigeminal neuralgia. Materials and Methods Retrospective analysis of MRI findings and surgical findings in 85 patients with trigeminal neuralgia. Results In 85 cases of trigeminal neuralgia, 170 cases of trigeminal nerve MRI examination of the cerebral cistern segment showed trigeminal vascular compression or contact on the 59 side and suspicious contact on 35 sides. The symptomatic side had neurovascular compression and the contact or suspected contact was 75 Side, by statistical analysis, trigeminal neuralgia in patients with and without the presence of vascular compression or contact was significant (P <0 01); 85 patients with symptomatic lateral surgical treatment of intraoperative vascular compression or confirmed According to the results of surgery, the sensitivity and specificity of MRI in diagnosing neurovascular compression or contact of trigeminal neuralgia were 88.2% and 94.4%, respectively. The specificity of suspicious contact in diagnosing neurovascular disease was 76.2%. Conclusion MRI can clearly show the relationship between the segment of the trigeminal nerve and the adjacent vessels. It is of high specificity and sensitivity for the correct diagnosis of trigeminal vascular compression or contact and is extremely important in providing preoperative evaluation and guiding treatment significance
