经皮激光椎间盘减压术治疗颈性眩晕

Percutaneous laser disc decompression for cervical vertigo

目的探讨经皮激光问盘减压术治疗颈性眩晕的疗效及机制。方法 2000年10月至2004年10月,我们使用 Nd:YAG 激光治疗机(波长1064nm),对42例颈性眩晕患者进行了经皮激光间盘减压术,术后进行2个月以上随访,观察患者眩晕的改善情况。结果患者均获得随访,随访时间2～36个月,平均7.5个月。术后2个月时,28例眩晕消失(67%),6例明显改善(14%),无效者8例(19%),优良率为81%,无神经损害、感染等并发症发生。结论经皮激光椎间盘减压术可使椎间盘内压降低,加之局部直接热疗,从而消除椎动脉痉挛,对治疗颈性眩晕有明显疗效。

Objective To investigate the curative effect and mechanism of precutaneous laser disc decompression for the treatment of cervical vertigo. Methods From October 2000 to October 2004, 42 patients with cervical vertigo were treated with percutaneous laser disc decompression by applying a Nd：YAG laser （ wavelength is 1064 nm）. The postoperative follow-up period was more than 2 months, the change of patients＇ vertigo were observed. Results All the patients were followed up. The mean follow-up period was 7. 5 months （ from 2 to 36 months）. After 2 months of posteroperative, 28 patients＇ vertigo disappeared （67%）, 6 patients＇ vertigo improved（ 14% ）, 8 patients＇ vertigo did not improve. The effective rate was 81%, there was no complication （infection and nerve injury）. Coneluslons Cervical intervertebral disc protrusion and cervical spine instability irrigate the neck sympathetic nerve, result in the spasm of vertebral artery, which is the main cause of cervical vertigo. Percutaneous laser disc decompression can decrease intradiscal pressure, increase local temperature, remove the spasm of the vertebral artery. The therapeutic effect for the treatment of cervical vertigo was remarkable.
