原发三叉神经痛神经根部的病理观察报告

目的探讨原发三叉神经痛神经根部的病理变化。方法同期观察78例原发三叉神经痛患者在行三叉神经根微血管减压并蛛网膜松解时的三叉神经根部病理变化(神经根,蛛网膜,责任血管及其相互关系。),并随机抽样留取蛛网膜送病理检查。结果术中观察78例三叉神经根部的蛛网膜均有炎性反应,47例蛛网膜与神经,血管有粘连但能分离,31例不易分离,且神经根无光泽并不同程度的变细。有明确的责任血管压迫48例,无责任血管压迫30例。40例随机抽样病理结果全部存在炎性反应,其中32例炎性细胞浸润及合并轻度至中度水肿,8例同时合并钙化,其中有责任血管压迫28例,未见责任血管12例。结论原发三叉神经痛患者三叉神经根部除微血管压迫、神经纤维脱髓鞘变外,还存在炎性反应。

Pathologic observing of surronding nerve root for the primary trigeminal neuralgia

Objective:To investigate the pathologic changes of surronding nerve root for the primary trigeminal neuralgia.Methods: Observing 78 cases pathologic changes of the trigeminal nerve s roots(the nerve s roots,arachnoid,reponsible vessels and the interreaction among them) by operative microscope in the microvascular decompression and arachnoid relax surrounding nerve root of the primary trigeminal neuralgia.Then sampling at rondom doing pathologic examination of the arachnoid.Results: 78 cases observed during...
