经皮激光椎间盘汽化减压术治疗腰椎间盘突出症的中期疗效分析

目的探讨经皮激光椎间盘汽化减压术（percutaneous laser disc decom pression,PLDD）治疗单纯腰椎间盘突出症的临床疗效。方法2001年5月～2006年12月,应用PLDD治疗单纯腰椎间盘突出症122例,采用半导体激光仪,局部麻醉,俯卧位,术中在C形臂X线机透视定位下调整进针角度和深度,光纤由浅入深插入烧灼,每次汽化1s,脉冲间隔5s,一般汽化3次,平均汽化总量不超过1500J,随访术后临床效果。结果122例随访6～60个月,平均36.5月,按MacNab疗效评定标准,优60例,良39例,可15例,差8例。优良率81.1%（99/122）。无并发症发生。结论PLDD具有创伤小、恢复快、安全有效等优点,是治疗单纯腰椎间盘突出症的较好方法。

Mid-term Efficacy of PLDD for Treatment of Lumbar Disc Herniation

Objective To investigate the mid-term efficacy of percutaneous laser disc decompression（PLDD） for patients with lumbar disc herniation.Methods Between May 2001 and December 2006,a total of 122 patients with simple lumbar disc herniation underwent PLDD in our hospital.Under local anesthesia,the operaiton was performed using a laser diode with the patients in supine position.A C-arm X-ray system was employed to guide the surgery.Results The patients were followed up for 6 to 60 months（mean 36.5 months）.Accroding to the MacNab Criteria,60 patients achieved excellent outcomes,39 were good,15 were fair,and 8 were poor.The rate of exellent and good outcomes was 81.1%（99/122）.No patient had postoperative complications.Conclusions PLDD is effective and safe for patients with simple lumbar disc herniation.The cases recover quickly after the operation,because the procedure is minimally invasive.
