为观察Chiari畸形伴脊髓空洞 (chiari -malformationandsyringomyelia,CM SM)患者手术治疗效果 ,我们对我科 1 993～ 1 996年CM SM的 51例手术治疗患者 ,术后 3年以上 ,对其术后残留的神经功能障碍及病程长短的关系进行研究。结果 :多数病例 ( 86% )手术效果满意 ,以脊髓后角为中心的损害、以脊髓前角为中心的损害、以脊髓侧索为中心的损害依次易有残留功能障碍。病程超过 2年者上肢运动功能障碍及病程超过 3年者感觉障碍易残留症状。作者认为 ,脊髓后角、前角的症状最易有术后残留 ,神经功能的恢复程度与病程长短密切相关 ,早期治疗对于预后至关重要。
To observe the surgical treatment of patients with chiari-malformation and syringomyelia (CM SM), 51 cases of surgical resection of CM SM from 1993 to 1996 in our department, more than 3 years after surgery, Neurological dysfunction and duration of the relationship between the study. Results: In most cases (86%), the operation effect was satisfactory, the damage centered on the dorsal horn of the spinal cord, the lesion centered on the spinal cord anterior horn, and the lesion centered on the lateral spinal cord were easily followed by residual dysfunction. Duration of more than 2 years of upper extremity motor dysfunction and duration of more than 3 years sensory disturbance easily residual symptoms. The author believes that the spinal cord posterior horn, the most likely symptoms of postoperative residual, the degree of recovery of neurological function is closely related with the duration of the disease, early treatment is crucial for the prognosis.
