腰椎间盘突出伴骶管囊肿的诊断与手术治疗

目的探讨腰椎间盘突出伴骶管囊肿的诊断与手术治疗方法。方法采取小切口开窗潜行减压髓核摘除及大部分切除、肌肉填塞交通孔处理骶管囊肿7例，并对其影像学检查方法及治疗方法进行分析。结果MRl可清楚显示骶管囊肿呈长T1及T2信号，信号强度与脑脊液一致。手术摘除突出髓核及处理骶管囊肿．能彻底解除压迫，疗效显著。结论MRI检查是诊断腰椎盘突出伴骶管囊肿的可靠方法；手术摘除突出的髓核及骶管囊肿是有效的治疗方法。

Diagnosis and surgical treatment of lumbar disc herniation combined with cyst in sacral canal

Objective To investigate the diagnosis and surgical treatment of lumbar disc herniation combined with cyst in sacral canal. Methods 7 cases were undergone removal of nucleus pulposus with small incision and fenestration, and excision of the most of the cyst wall and plugging the communicating hole with a block of muscle. Imageology observation and healing method were also evaluated. Results Long T1 and T2 signals of the cyst in sacral canal could be clearly showed in MRI, and the signal tensity was the same as that of cerebrospinal fluid. Operative treatment was a good method for lumbar disc herniation combined with cyst in sacral canal, which could remove compression, and therapeutic efficacy was predominance. Conclusions MRI is a good image method for lumbar disc herniation combined with cyst in sacral canal, and operative treatment is a very effective way.
