颅后窝重建术治疗Chiari I畸形合并脊髓空洞症

Posterior fossa reconstruction in the treatment of Chiari I malformation associated with syringomyelia

目的探讨后颅窝重建术(后颅窝减压+硬脑膜成形+小脑扁桃体切除+蛛网膜粘连分解)治疗Chiari I畸形合并脊髓空洞症的方法及疗效。方法 2002年11月至2008年1月对收治的46例Chiari I畸形合并脊髓空洞症患者行后颅窝重建术。结果后颅窝重建术症状改善率84.8%,脊髓空洞长度明显减小,KPS评分显著改善。结论后颅窝重建术是治疗Chiari I畸形合并脊髓空洞症较为合理的术式。

Objective To evaluate posterior fossa reconstruction（posterior cranial fossa decompression,duraplasty,resection of the cerebellar tonsil and separation of the arachnoid membrane from the dura） in the treatment of Chiari I malformation.Methods A total of 46 patients suffered from Chiari I malformation associated with syringomyelia received posterior fossa reconstruction in our department from November 2002 to January 2008.Results The rate of symptom improvement post-operation was 84.8%.The length of syringomyelia was decreased significantly and KPS got remarkable improvement.Conclusion Posterior fossa reconstruction is a rational option for the treatment of Chiari I malformation associated with syringomyelia.
