摘　　要：目的探讨超声检查在脊髓栓系综合征(TCS)中的临床应用。方法分析45例TCS患儿的超声声像图,并应用彩色多普勒记录脊髓末端圆锥血流速度,对术前及术后血流速度测值进行比较。结果超声不仅与CT一样能提供TCS解剖和病理改变的图像,且能显示TCS在超声检查中的特征表现,即脊髓远端动态脉跳搏动消失。利用彩超检测脊髓远端的血供情况,术前脊髓末端圆锥血流速度(0.047±0.012)m/s,术后血流速度(0.158±0.029)m/s,两组比较有显著差异(P<0.01)。结论超声对术前诊断TCS有实用价值,对手术前后评估脊髓远端血供有其重要的作用。Objective To explore the clinical application of uhrasonography on tethered spinal cord syndrome （TCS）. Methods Ultrasonic feature of 45 patients with TCS were analyzed retrospectively. Pre - and post - operative blood flow rates of cone were recorded by color doppler. Results Ultrasound was the same as computer tomography not only presented the image of anatomy and pathology of TCS, but also showed the lack of pulsatile motion of distal cord with TCS. Before the operation, blood flow rates of cone were（ 0. 047 ± 0.012 ） m/s. After the operation, blood flow rates of cone were（0.158± 0. 029） m/s. There was significantly different （P〈 0.01 ）. Conclusions Uhrasonography may provide clinical valuable information in diagnosis of TCS preoperation. It plays a unique role in as.saying the blood supply before and after operation.
