三叉神经根显微血管减压术治疗三叉神经痛87例

Clinical Analysis of microvascular decompression for trigeminal neuralgia

目的:探讨显微血管减压术治疗三叉神经痛的价值。方法:回顾分析经显微血管减压术治疗的87例三叉神经痛患者的临床资料,术中见小脑上动脉压迫38例,接触11例;小脑前下动脉压迫19例,接触7例;小脑上动脉和小脑前下动脉同时压迫9例;无名静脉接触3例。伴蛛网膜粘连增厚43例。结果:术后痊愈78例(89.7%),部分缓解7例(8.0%),无效2例(2.3%)。结论:显微血管减压术治疗三叉神经痛疗效显著,尤其对神经受动脉压迫而出现明显压迹者效果更佳。

Objective:To evaluate the effects of microvascular decompression on trigeminal neuralgia. Methods:Data from 87 trigeminal neuralgia cases treated with microvascular decompression were analyzed retrospectively and systematically. During the operation we found superior cerebellar artery was pressed in 38 cases and touched in 11 cases; anterior inferior cerebellar artery was pressed in 19 cases and touched in 7 cases; both superior cerebellar artery and anterior inferior cerebellar artery were pressed in 9 cases; innominate vein was touched in 3 cases; and adhered and thickened arachnoid was found in 43 cases. Results:In 87 trigeminal neuralgia cases,78 cases(89.7%)had recovered;7 cases(8.0%)had improved;2 cases(2.3%)did not changed. Conclusion: Microvascular decompression is a safe and efficient way to treat trigeminal neuralgia , especially when there is a marked notch on the trigeminal nerve due to artery compression.
