Clinical application of percutaneous laser disc decompression for treatment of lumbar intervertebral disc protrusion

Objective To evaluate the clinical value of percutaneous laser for the treatment of lumbar intervertebral disc protrusion. Methods Percutaneous laser disc decompression (PLDD) was performed in 86 cases with 144 lesions of lumbar intervertebral disc protrusion with semiconductor laser. Under guidance of X-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. A follow-up for 3 months to 3 years was conducted. Results The total efficiency was 78% (67/86). The re-puncture rate was 3.4%. Surgical operation rate after PLDD was 5.8%. No serious complication was found. Conclusion PLDD is a simple, effective, and safe interventional method for the treatment of lumbar intervertebral disc herniation.
