Surgical treatment of Chiari malformation complicated by syringomyelia

目的 探讨治疗Chiari畸形合并脊髓空洞症的手术方法及其效果。方法 对 4 1例Chiari畸形合并脊髓空洞症病例采用不同手术方式进行治疗 ,31例行颅后窝减压术 ,10例行显微颅后窝减压 +硬膜扩大成形术。结果 采用颅后窝减压术的 31例中有 2 8例 (占 90 .3% )症状好转 ,采用显微颅后窝减压 +硬膜扩大成形术的 10例症状均较术前明显好转。结论 对Chiari畸形合并脊髓空洞症病例采用颅后窝减压术 ,疗效较满意 ;采用显微颅后窝减压 +硬膜扩大成形术可提高疗效 ,减少并发症。

Objective To discuss the treatment of Chiari malformation complicated by syringomyelia.?Methods 41 cases of Chiari malformation were treated by varied procedures, i.e. posterior fossa decompression in 31 cases, and posterior fossa decompression by microsurgical technique plus repair of the dura in 10 cases.?Results In 28 of the 31 cases having undergone posterior fossa decompression, the clinical syndromes were ameliorated, but the syndromes got obviously ameliorated in all of the 10 cases treated by posterior fossa decompression and repair of the dura.?Conclusion Satisfactory results can be achieved by posterior fossa decompression for Chiari malformation complicated by syringomyelia. Posterior fossa decompression by microsurgical technique plus repair of the dura can improve the results and decrease the complications.
