TANG Yi, et al. Clinical use of ultrasonography for tethered spinal cord syndrome[J]. Journal of Chongqing Medical University, 2004,(5):651-653. DOI: 10.13406/j.cnki.cyxb.2004.05.027.
Objective:To discuss the value of ultrasonography for tethered spinal cord syndrome (TCS).Mothods:Ultrasonic features of 31 patients with TCS were analyzed.Pre-and post-operative blood flow rates of cone were recorded by color Doppler and compared.Results:Ultrasound could present the image of pathology of TCS.The study could show the lack of pulsatile motion of distal cord with TCS.Before the operation blood flow rates of cone are 0.048±0.015m/s.After the operation blood flow rates of cone are 0.156±0.027m/s.The above results were significantly different ( P <0.01).Conclusion:Ultrasonography can provide clinical valuable information in the diagnosis of TCS pre-operation.It plays the unique role in assaying the blood supply before and after the operation.
