采用显微血管减压术治疗三叉神经痛

目的：总结近年采用显微血管减压手术治疗三叉神经痛的方法和结果，以期进一步提高手术治愈率。方法：回顾分析从1994年1月至2003年12月进行后颅窝手术探查的21例原发性三叉神经痛患者。19例行显微血管减压术。有1例术中采用脑室镜协助观察。结果：在头颅磁共振扫描上，有11例可见疼痛一侧的桥脑旁有异常血管影。术中发现三叉神经出脑干处有血管压迫者19例(动脉血管压迫16例，静脉血管压迫3例)。19例中，术后早期疼痛完全缓解17例。结论：显微血管减压术是治疗原发性三叉神经痛的安全和有效的方法。

SURGICAL TREATMENT OF TRIGEMINAL NEURALGIA USING MICRO-VASCULAR DECOMPRESSION

Objective : To study the recent surgical method and results of micro-vascular decompression for trigeminal neuralgia, to improve surgical successful rate. Method: We retrospectively reviewed 21 patients undergoing surgical exploration via posterior cranial fossa for primary trigeminal neuralgia between Jan., 1990 and Dec, 2003. Micro-vascular decompression operations were applied in 19 cases. Endoscopic technique was used to assist the operation in 1 case. Results: MRI showed abnormal vessels adjacent to the pons in 11 cases. Vascular compression was noticed in the root entry zone in 19 cases (arterial in 16, venous in 3). Immediate postoperative total pain relief was achieved in 17 cases. Conclusions: Micro-vascular decompression operation is safe and effective for the patients with primary trigeminal neuralgia.
