To investigate the curative effect and mechanism of transcutaneous laser disc decompression for the treatment of cervical vertigo.
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.
All the patients were followed up. The mean follow-up period was 7.5 months (from 2 to 36 months). After 2 months of postoperative, 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).
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.
探讨经皮激光椎间盘减压术治疗颈性眩晕的疗效及机制。
2000年10月至2004年10月，应用Nd:YAG激光（波长1064nm）对42例颈性眩晕患者行经皮激光椎间盘减压术。术后随访2个月以上，观察患者眩晕变化情况。
全部患者均获随访，平均随访时间7.5个月（2～36个月）。术后2个月时，眩晕消失28例（67%），眩晕改善6例（14%），眩晕无改善8例。有效率为81%，无并发症（感染、神经损伤）发生。
颈椎间盘突出及颈椎失稳刺激颈部交感神经，引起椎动脉痉挛，是颈性眩晕的主要原因。经皮激光椎间盘减压术可降低椎间盘内压力，提高局部温度，解除椎动脉痉挛，治疗颈性眩晕疗效显著。
