摘要
作者报告了我院经皮椎间盘切除术（ＰＬＤ）治疗腰椎间盘突出症４２７例患者的结果。穿刺成功率达１００％，总有效率达９４％。重点分析了疗效与适应证，疗效与间盘组织切吸量及病程长短的关系。认为，疗效与适应证的选择及间盘组织的切吸量有密切关系（间盘组织的切吸量大于２ｇ者的疗效较好），而与病程的长短无明显关系。讨论了手术可能发生的并发症及疗效判断时间，论证了ＰＬＤ的治疗机理，发现ＰＬＤ可改变残存髓核突出的方向，预防术后症状的复发。指出，有小部分钙化的椎间盘突出仍可应用ＰＬＤ进行治疗。
The authors reported the resuIts of percutaneous lumbar discectomy(PLD)in 427 cases.The puncture success rate was 100%,the overall effective rate was 94%。Analysis was made and confirmed the correlation of the therapeutic effect of PLD to the choice of the candldates and the amount of disc tissue removed,which when exceeding 2g would yield better clinical result.However,no obvious relation was found between the therapeutic effect and duration of the illness. The authors also discussedon the complications usually encountered and the right time to judge the resuIt as well as the mechanism of PLD; It was found that PLD might induce a change in the direction of disc pro- trusion as shown on CT image after PLD. The authors were of the opinion that disc with small amount of calcification might possibly be treated with PLD.
