经皮激光颈椎间盘减压术的临床研究

Clinical study of percutaneous laser disc decompression

目的探讨经皮激光椎间盘减压术治疗颈椎间盘突出症的临床运用价值。方法使用ND：YAG激光治疗颈椎间盘突出症10例,其中C4-5椎间盘突出6例,C5-6和C4-5同时突出4例,C臂透视下将激光光纤沿穿刺针插入椎间盘髓核中进行汽化,每节总量250-500 J能量进行汽化,从而减轻椎间盘内压力。结果椎间盘内压力减低,神经根受压解除,突出的椎间盘组织回缩,10例患者其优良率为90%。结论经皮激光颈椎间盘减压术是一种安全、简单、有效的治疗椎间盘突出症的微创方法,因此必将受到广大患者的欢迎。

Objective To evaluate the clinical value of percutaneous laser for the treatment of cervical disc herniation.Methods Percutaneous laser disc decompression（PLDD） was performed in 16 cases with cervical disc herniation,including 6 cases of C4-5 and 4 cases of C5-6and C4-5 disk with ND：YAG laser.Under guidance of C-ray fluoroscopy,a needle was punctured into the lumbar disc.and the laser fiber was introduced into the disc center through needle tube,and then the laser was vaporized.During the process,the gas was aspirated from the disc continually.And the energy was up to 250~500J joules.Results The pressure of the intervertebral disc was reduced,and the compression of nerve root and annulus fibrosis the protrusion was relieved.the total efficiency was 90%.Conclusion Percutaneous laser disc decompression（PLDD） is a safe,effective,simple method for the treatment of intervertebral disc protrusion.And the trauma is small.Its effect is positive.
