目的:探讨CT导引PLD的价值及对疗效评价。方法:本组142例计164个椎间盘,突出脱出者136个,膨出者28个。切割前先对靶椎间盘进行薄层扫描,并作穿刺参数的测量,所有病例均在CT监控下进行穿刺、切割。结果:穿刺成功率100%,无1例发生并发症。显效率651%,有效率2965,无效率53%。结论:1、CT导引有利于选择进针途径和穿刺入点,测量的穿刺参数真实、准确;可及时观察椎间盘被切割的范围和还纳复位情况,并免除了术者的X线的损伤。2、指出髓核突出伴软骨结节形成,外科术后复发仍可应用PLD治疗,对L5～S1行PLD时,CT更有利于选择进针途径;3、指出有些椎间盘还纳与术后即时疗效不呈正比关系
Objective: To investigate the value of CT-guided PLD and evaluate its curative effect. Methods: The group of 142 cases count 164 discs, highlighting out of 136, bulging 28. Prior to cutting, the target intervertebral disc was scanned thinly and puncture parameters were measured. All cases were punctured and cut under the control of CT. Results: The puncture success rate was 100%, no complications occurred. Significantly effective 651%, effective 2965, ineffective 53%. Conclusions: 1, CT guidance is conducive to the selection of the needle approach and puncture into the point, the measured puncture parameters are true and accurate; can be observed in time to cut the scope of the disc and also accept the reset situation, and remove the surgeon’s X-ray damage . 2, pointed nucleus pulposus prominent with cartilage nodules, surgical recurrence can still be applied PLD treatment, L5 ~ S1 line PLD, CT is more conducive to select the needle approach; 3, pointed out that some of the intervertebral disc also satisfied with the postoperative instant Efficacy is not proportional relationship
