经皮激光椎间盘减压术治疗颈性眩晕的临床研究

目的探讨经皮激光椎间盘减压术治疗颈性眩晕的疗效及机制。方法对31例颈性眩晕患者36个突出间盘行经皮激光椎间盘减压术，观察术后3个月以上的疗效。结果28例术后眩晕立即消除(90％)，明显改善者2例(7％)，无效者1例(3％)，无神经损害、感染等并发症发生。结论导致颈性眩晕的主要原因是颈椎间盘突出、颈椎失稳，激惹交感神经诱发椎动脉痉挛。钩突关节肥大并非是主要致病因素。经皮激光椎间盘减压术使椎间盘内压骤然降低，加之局部直接热疗，从而可消除椎动脉痉挛，对治疗颈性眩晕有明显疗效。

The clinical study on precutaneous laser disc decompression for the treatment of cervical dizziness

Objective To investigate the therapeutic effect and mechanism of precutaneous laser disc decompression (PLDD) on the treatment of cervical dizziness. MethodsThirty-six protrusion discs of 31 cases of cervical dizziness underwent PLDD. The patients were followed up for over three months after operation, and the therapeutic effects were observed. ResultsThe dizziness disappeared in 28 cases (90%), improved in 2 cases (7%), and did not improve in 1 case (3%). There was no complication such as nerve injury or infection in all cases. Conclusion Cervical intervertebral disc protrusion and cervical instability stimulate the sympathetic nerve and result in the spasm of vertebral artery, which are the main causes of cervical dizziness. Uncovertebral joint hypertrophy is not the main cause of cervical dizziness. PLDD can decrease the inner compression of disc suddenly with increasing the local temperature directly so as to preclud the spasm of the vertebral artery, so the therapeutic effect on the treatment of cervical dizziness is remarkable.
