摘要
目的探讨硬脊膜内层Saito切除技术治疗脊膜瘤的手术技术和临床疗效。方法应用Saito技术治疗36例脊膜瘤，术中显微镜下将硬脊膜分为内外两层，将肿瘤和与之相连的硬脊膜内层切除，完整保留硬脊膜外层并严密缝合。结果36例脊膜瘤全切除，平均随访31个月（12—72个月），无手术相关并发症和肿瘤复发。外层硬脊膜病理组织学检查未见肿瘤生长。结论硬脊膜内层Saito切除技术治疗椎管内脊膜瘤，在切除肿瘤蒂部硬脊膜内层同时可以保留硬脊膜外层，减少术后脑脊液漏的风险，值得临床推广应用，但远期临床效果尚需进一步随访。
Objective To describe and discuss Saito technique for surgical resection of spinal mcningiomas. Method In the surgical procedure of a small incision was made in the surface of the dura mater after the conventional laminectomy. The spinal dura could be easily divided into two layers, comprising inner and outer layers. The outer layer was stripped away from the inner layer surrounding the tumor base. The tumor was then resected together with the inner layer alone outside the arachnoid membrane, and finally the outer layer was simply closed. Results Saito technique has been applied to thirty - six cases. Neither complications nor tumor recurrence have been experienced followed up for a mean time 31 months （ range 12 - 72 months）. The preserved outer layer of the dura mater did not demonstrate the existence of tumor ceils histologically. Conclusions The authors introduced Saito technique for surgical resection of isolated intradural spinal meningioma. Using Saito procedure the outer part of the dura mater, which is not involved by the tumor,can be preserved and complicated dural reconstruction is not necessary. Furthermore, there is less risk of postoperative cerebrospinal fluid fistulas than when the dura is completely resected together with the tumor. However, long term observation as a result of the possibility of local recurrence is strongly recommended.
