目的：为了探寻脊髓栓系综合征简便易行的检查方法。方法：选择近期术前行Ｂ超检查的１０例脊髓栓系综合征患儿，将其术中所见与术前Ｘ线、ＣＴ（７／１０）、ＭＲＩ（３／１０）及Ｂ超检查与术中所见进行回顾性比较。结果：发现术前Ｂ超检查与术中所见相似，而且简便，能详细了解病变及动态观察脊髓搏动情况。结论：Ｂ超检查对脊髓栓系综合征的诊断、指导手术及术后随访具有重要意义，是一种简便易行、无损伤的检查诊断方法 Objective: In order to explore the tethered cord syndrome method easy to check. Methods: Ten children with tethered cord syndrome who underwent B-mode ultrasonography before surgery were selected. The findings were compared with preoperative X-ray, CT (7/10), MRI (3/10) and B-ultrasound Retrospective comparison with intraoperative findings. Results: It was found that preoperative B-ultrasound and intraoperative findings similar and simple, can learn more about lesions and dynamic observation of spinal pulsation. Conclusion: B-ultrasound is of great importance to the diagnosis, guidance and follow-up of tethered cord syndrome. It is an easy and feasible method to diagnose and treat the tethered cord syndrome
