脊髓纵裂神经缺陷机制探讨

对２９例脊髓纵裂的神经功能状态进行临床评价及胫后神经皮层体感诱发电位检查，结果 ：患病组２９例两下肢间神经缺陷的临床评分及ＰＴＮＣＳＥＰ有显著差异，患病组２９例的５８根ＰＴＮＣＳＥＰ明显异常；手术组２０例间隔切除术后神经缺陷的临床评分及ＰＴＮＣＳＥＰ异常明显改善，非手术组９例１年关随访时则无改善。

Study of Mechanism of Neural Deficit in Diastematomyelia

29 patients with diastematomyelia ( 20 patients in operative group, 9 patients in conservative group). were studied by evaluating clinical neural function and measuring posterior tibial nerve cortical somatosensory evoked potentials (PTNCSEP). The results were that clinical scores and PTNCSEP had significant difference between bilateral lower extremities in 29 patients(P< 0. 05). Clinical scores and PTNCSEP improved significantly in operative group(P<0.05), and had not significant improvement in conservative group(P>0. 05). It showed that the mechanism of neural deficit was traction of the septum to the spinal cord and asymmetrical developmental anomalies of the cord.
