摘要 目的评价小脑扁桃体下疝切除术治疗Chiari畸形并脊髓空洞的临床效果。方法本组Chiari畸形合并脊髓空洞患者10例均采取手术治疗。手术时有效范围后颅窝骨性减压,铣刀铣开小范围后颅窝骨瓣(3cm×3cm),不切除C1后弓,直线侧切开硬脑膜,切除下疝的小脑扁桃体,松解脊髓中央管开口隔膜,疏通第四脑室脑脊液各输出道,使脑脊液循环通畅,原位缝合硬脑膜,颅骨锁固定骨瓣。结果手术无死亡及病残病例。10例术后(12d内)MR示小脑扁桃体下缘上升到枕骨大孔水平以上,后颅窝内容积扩大。术后长期随访9例,随访时间6个月~2年,2例患者症状逐渐改善,6例稳定未加重,1例较术前略加重,但MR示后颅窝内容积扩大,脊髓空洞缩小。结论小脑扁桃体下疝切除术治疗Chiari畸形并脊髓空洞患者,术后后颅窝内容积扩大,第四脑室内脑脊液循环通畅,临床症状多有改善。
