超声影像诊断在脊髓栓系综合征中的临床应用

Clinical use of ultrasonography for tethered spinal cord syndrome

目的 :探讨超声检查在脊髓栓系综合征中的临床应用价值。方法 :对 31例脊髓栓系综合征的声像图进行总结分析 ,并应用彩色多普勒记录脊髓圆锥血流速度 ,将术前及术后血流速度测值进行比较。结果 :超声能提供脊髓栓系综合征病理改变的声像图 ,显示脊髓栓系综合征在超声检查中具有的特征表现 ,即脊髓远端搏动消失。术前脊髓末端圆锥血流速度测值 0 .0 4 8± 0 .0 15m/s,术后脊髓末端圆锥血流速度测值 0 .15 6± 0 .0 2 7m/s,两组比较P <0 .0 10。结论 :超声在术前诊断脊髓栓系综合征中有临床实用价值 。

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.
