摘要 目的探讨脊髓亚急性联合变性(SCD)的病因、临床特点、治疗及预后。方法对2005年5月-2010年6月我院收治的11例SCD患者的临床资料进行回顾性分析。结果11例病人均有脊髓后索受累,其中8例(72.7%)伴脊髓锥体束受累,5例(45.5%)伴脊髓丘脑束受累,8例(72.7%)伴周围神经受累,3例(27.3%)伴自主神经系统受累,表现为大小便功能障碍。72.7%(8/11)伴有巨幼红细胞贫血(MA)。66.7%(4/6)血清维生素B12(VitB12)水平降低。100%(7/7)患者肌电图有异常改变。66.7%(6/9)的患者脊髓MRI发现后索和(或)侧索特异性改变,主要位于上颈部段及中胸段脊髓。所有患者经甲钴胺治疗均有不同程度好转。结论SCD除可累及脊髓后索,侧索中锥体束,周围神经外,还可累及侧索中脊髓丘脑束及自主神经系统。维生素B12缺乏是SCD的主要病因。应用维生素B12是治疗SCD的关键。早期及时治疗可改善预后。
