CT引导经皮椎间孔镜治疗L3~4椎间盘突出症

         

摘要

目的 探讨CT引导经皮椎间孔镜治疗L3~4椎间盘突出症的穿刺技巧及临床疗效. 方法 行CT引导经皮椎间孔镜手术治疗61例L3~4椎间盘突出患者,1例因既往行同节段开放手术椎间隙狭窄而采用侧前方穿刺入路,其余患者全部采用后外侧入路(神经根前/后). 其中L3~4 46例,L2~3、L3~4 1例, L3~4、L4~5 14例.通过64排CT后处理系统在患者术前腰椎CT上测量L3~4、L4~5椎间孔位置神经根的走行角度,并比较L3、L4出口根走行角度的差异.结果 61例患者均获随访,时间7~31(16. 2 ± 6. 4)个月. 术后未出现复发、脑脊液漏及神经根损伤,肢体遗留麻木6例(9. 8%). 61例患者L3 出口根走行角度平均为11. 3° ± 3. 2°,L4 出口根走行角度平均为26. 8° ±6. 9°,两者比较差异有统计学意义(t=11. 42,P<0. 01). JOA评分:术前(13. 9 ± 4. 0)分,术后1周(25. 8 ± 2. 7)分,末次随访时(26. 9 ± 3. 2)分,术后1周及末次随访与术前比较差异均有统计学意义(P<0. 01). 其中优44例,良12例,一般5例,优良率91. 8%. 结论 熟悉L3~4椎间孔的解剖,掌握该位置神经出口根的走行及其与L4~5的差异,辅以CT引导,可真正实现靶点穿刺、安全高效地摘除L3~4突出髓核组织.%Objective To explore the puncture technique and clinical efficacy of the CT-guided percutaneous transfo-raminal endoscopic discectomy for L3~4 disc herniation. Methods 61 cases of L3~4 disc herniation underwent CT-guided percutaneous transforaminal endoscopic surgery. Except one case used the front side puncture approach be-cause of its disc space narrowing after open surgery, the remaining cases were in all lateral approach ( nerve root be-fore/after) . Among them, L3~4 46 cases, L2~3 +L3~4 1 case, L3~4 + L4~5 14 cases were included. Measurement and analysis the walk-angle of the patient with L3~4 and L4~5 intervertebral foramen nerve root in the 64-slice CT post-processing system, compared the difference of L3 , L4 nerve export root. Results All 61 patients were followed up for 7~31 (16. 2 ± 6. 4) months. Recurrence,cerebrospinal fluid leakage and nerve root injury didn′t appear,legacy numbness in 6 cases (9. 8%). 61 cases of patients with L3 export root traveling angle for average of 11. 3° ± 3. 2°, L4 export root traveling angle for average of 26. 8° ± 6. 9°, the results were statistically significant ( t =11. 42, P <0. 01). JOA scores:the preoperative was 13. 9 ± 4. 0, one week postoperation 25. 8 ± 2. 7,and the last follow-up 26. 9 ± 3. 2. The last follow-up,one week postoperation and the preoperative JOA scores difference were statistically significant (P<0. 01). Excellent in 44 cases, good 12 cases, fair 5 cases,with the excellent good rate of 91. 8%. Conclusions Familiar L3~4 intervertebral foramen anatomy, grasp the position of nerve export root and differences between L4~5 , combined with CT-guided, L3~4 nucleus can be removed safely.
