化学溶核术术后影像学的改变

Alteration of Radiographical Features after Chemonucleolysis

目的:探讨有关(胶原酶)化学溶核术后相应影像学方面的变化。方法:对90例椎间盘突出患者行化学溶核术术前、术后腰椎X线及CT进行对比研究。结果:术后CT改变有4种类型,消失型、缩小型、CT值降低型和无变化型。3.33％患者术后出现继发性腰间盘膨出,6.67％术后出现椎间盘隙变窄。结论:化学溶核术的临床疗效与术后CT的改变有明显的联系。

Objective: To investigate the alteration associated with collagenase of radiographical features after chemonucleolysis. Methods: The contrastive study of computer temography (CT) and radiographs of lumbar spine was performed in 90 patients with hernialed lumbar discs before and after chemonucleoiysis. Results: The changes of CT after chemonucleoiysis were divided into hernia disappearance, hernia reduction, C'l value reduction and unchanged types. Among the patients, 3.33% developed the protrusion of intervertebral disc. 6.67% showed the narrowing of intervertebral space. Conclusion: There is an obvious correlation between clinical results arid changes of CT after chemonucleoiysis.
