三叉神经受压位置的MRI与三叉神经痛的相关研究

目的：探讨三叉神经痛与血管压迫神经的位置关系。方法：回顾性分析50例有神经血管压迫症状患者的临床和MRI表现，其中40例有三叉神经痛，10例无三叉神经痛。结果：40例有三叉神经痛患者的MRI表现中35例（87．5％）显示血管压迫三叉神经根进入区（REZ）处，5例（12．5％）显示压迫三叉神经节前段（PGS）处；10例无三叉神经痛患者的MRI表现中4例（40％）显示压迫REZ处，3例（30％）显示压迫PGS处，3例（30％）显示压迫三叉神经门进入区（PEZ）处。结论：大部分三叉神经痛患者的神经血管压迫位于REZ处。

Trigeminal Neuralgia: Comparative Study of Neuralgic Manifestation and Site of Neurovascular Compression MR Imaging

Objective:To evaluate the relationship between trigeminal neuralgia and site of trigeminal nerve compression.Methods:The magnetic resonance (MR) imaging and clinical symptoms of 50 cases with trigeminal nerve compression were retrospectively analysed.Results:In 40 of 50 patients who were trigeminal neuralgia.Thirty-fives (87.5%) of 40 patients with NVC at the site of the REZ,5 (12.5%) of 40 patients with NVC at the site of the PGS.In 10 patients who were not trigeminal neuralgia,4 (40%) of them with NVC at the site of the REZ,3 (30%) at site of the PGS and other 3 (30%) at the site of the REZ.Conclusion:A close relationship isfound between the neuralgic manifestation and the REZ site of trigeminal nerve compression.
