摘要 [目的]评价显微镜下over-the-top技术单侧通道双侧减压治疗单节段中央型腰椎管狭窄症的临床疗效。[方法]选取单节段腰椎管狭窄症患者30例,显微镜下over-the-top技术行单侧通道双侧减压术,记录手术时间、术中出血量、引流量、术后住院时间、并发症、手术前后站立时间和步行距离等情况;观察手术前后影像学变化;采用腰疼视觉模拟评分(VAS评分)和Oswestry功能障碍指数(ODI)评价患者腰腿痛及功能改善情况,术后1年随访时采用MacNab功能评分评价临床疗效。[结果]30例患者术中无脑脊液漏及脊髓损伤,手术时间60~140min,术中出血量50~300ml;术后下床活动时间6~24h,术后无切口感染、裂开等并发症发生。患者获12~24个月随访。术后复查CT显示椎管前后径、双侧侧隐窝直径均较术前扩大(P<0.05)。所有患者术后临床症状明显改善或消失。术后3d及末次随访时患者腰腿痛VAS评分和ODI指数较术前明显改善,差异均有统计学意义(P<0.05)。末次随访时采用MacNab标准评价临床疗效:优21例,良8例,可1例,优良率96.67%。[结论]显微镜下over-the-top技术行单侧通道双侧减压术治疗腰椎管狭窄,中期随访效果良好,远期疗效有待进一步随访观察。
