Quadrant通道下微创治疗复发性腰椎间盘突出症的近期疗效观察

目的评价Quadrant通道下微创治疗复发性腰椎间盘突出症的疗效。方法 2008年7月-2010年3月,对18例复发性腰椎间盘突出症患者采用Quadrant通道下椎间盘突出髓核摘除术治疗。其中男13例,女5例;年龄35～67岁,平均43岁。手术节段:L4、5 6例,L5、S1 12例。首次手术至复发时间为12～120个月,平均42.8个月。患者均行X线片、CT及MRI检查确诊原椎间盘再次突出。末次随访时采用疼痛视觉模拟评分(VAS)和改良MacNab标准评定患者症状改善情况。结果手术时间40～80 min,平均60 min;术中出血量80～120 mL,平均100 mL。手术切口均Ⅰ期愈合;术中2例发生脑脊液漏,未行修补,术后3 d拔除引流片后切口愈合。术后无椎间隙感染、神经损伤、定位错误等并发症发生。18例均获随访,随访时间12～30个月,平均22个月。末次随访时按改良MacNab标准评价疗效,获优12例,良6例。末次随访时,腿痛VAS评分由术前的(7.3±2.2)分降至(2.0±1.3)分,差异有统计学意义(t=11.08,P=0.00)。随访期间无复发。结论 Quadrant通道下椎间盘突出髓核摘除术具有创伤小、并发症少等优点,是治疗复发性腰椎间盘突出症的一种安全有效的微创手术方法。
