摘要
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（ＰＴＮＣＳＥＰ）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（Ｐ＜０．０５）；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（Ｐ＜０．０５），非手术组９例１年半随访时则无改善（Ｐ＞０．Ｏ５）。结果提示神经缺陷的机理是脊髓纵裂间隔对脊髓的牵拉和纵裂脊髓单侧发育异常。
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.
