摘要
目的:探讨磁共振体层血管造影(MRTA)对三叉神经痛的诊断价值。方法:回顾性地分析120例经手术治疗的三叉神经痛患者的MRTA表现及手术结果。结果:120例症状侧MRTA检查有血管压迫者为79侧,接触者为28侧,共107侧,敏感性为89.17%。120例症状侧行手术治疗,手术发现有血管压迫或接触者76侧,MRTA检查诊断神经血管压迫和接触的特异性分别为96.2%和82.14%。结论:MRTA成像作为一项新的影像学检查技术,能较好地显示三叉神经根与周围血管之间的关系,从而为三叉神经痛的病因诊断及临床的治疗提供可靠的影像学依据。
Objective：To evaluate diagnostic value of magnetic resonance tomographic angiography （MRTA） in trigeminal neuralgia. Methods：MRTA manifestations of 120 patients with trigeminal neuralgia were reviewed retrospectively and compaired with operative resuits. Results：79 sides had vascular compression at MRTA in sides-related symptoms and signs of 120 patients,28 sides had vascular contact. amount to 107 sides,the sensitivity was 89.17%. 76 sides with vascular compression or contact was found by the operation in sidesrelated symptoms and signs of 120 patients,the specificity of MRTA diagnosis of neurovascular compression and contact was 96.2% and 82.14 %. Conclusion： MRTA as a new imaging technique can display the trigeminal nerve to surrounding vascular structures preferably, and offer credible imaging evidence for pathogenetic diagnosis and clinic treatment of trigeminal neuralgia.
