CT检查在腰间盘突出症中的应用

目的：探讨和分析CT检查在腰间盘突出症的临床疗效，总结其临床价值。方法：回顾性分析具有完整临床资料的2007年10月至2011年10月来我院就诊的腰间盘突出症患者40例，采用CT检查用于手术前后的评价，为临床手术进行提供依据和参考。结果：经CT检查和治疗，按患者的临床症状和体征评价治疗腰椎间盘突出症的疗效。通过对患者进行观察和随访，术后2周后，所有患者的临床症状消失，临床体征逐渐恢复。有1例患者趾背伸缩力比术前有所减弱，未经特殊治疗1个月后恢复。所有患者均无感染情况的出现。结论：CT扫描检查是诊断腰椎间盘突出症和腰椎管狭窄症的有效方法，通过cT检查可以对髓棱的突出程度、部位以及性状作出判断。对手术后髓核摘除后的变化，CT图像的情况如摘除是否彻底、部位是否准确以及有无侧隐窝的狭窄等具有重要意义。

CT value analysis and clinical significance before and after percutaneous lumbar discectomy

Objective: To provide theoretical basis for effect and mechanism of percutaneous lumbar discectomy in clinic. Methods: A total of 180 patients with lumbar intervertebral disc herniation were evaluated by CT on the fifth day before and after operation. Meanwhile, CT value was measured in the determined level and region. Results: After operation, CT value of the central and posterior determined point of herniated intervertebral disc was lower significantly than that before operation ( P<0.01 ), but CT value of the anterior determined point was different insignificantly. The excellent and good results of the patients together were 83% postoperatively. Conclusions: The curative effect of percutaneous lumbar discectomy is achieved through reduction of lumbar intradiscal pressure.
