摘要 目的:探讨Arnold.Chiari畸形合并脊髓空洞患者行枕下减压术中采用人工硬脑膜扩大修补术的临床效果。方法17例Arnold—Chiari畸形患者,术前经MRI证实,均有小脑扁桃体疝入枕骨大孔以下及脊髓空洞,并有不同程度的运动感觉障碍及小脑和末组脑神经症状。行枕下减压术中,适当咬除枕骨,寰椎后弓咬除2cm左右,松解寰枕筋膜后,打通第四脑室脑脊液循环,予以人工硬脑膜扩大修补术,严密缝合硬脑膜。为防止脑脊液漏,8例使用生物蛋白胶辅助封闭。结果17例患者中,术后随访时间1.0±2.5(1.54±0.3)年,其中2例1年后失访。16例患者症状消失或症状改善,1例症状无变化。复查MRI示减压充分,脊髓空洞均有不同程度缓解。结论人工硬脑膜扩大修补术可以有效地缓解后颅窝压力,改善脑脊液循环,但需注意严密缝合,防止脑脊液漏所致皮下积液和术后感染。
