摘要
目的用高频超声观察兔坐骨神经急性损伤的超声图像表现,评价其临床诊断价值。方法16只健康家兔随机分为4组,建立兔坐骨神经急性损伤模型,分别在损伤后第1、2、4、8周,应用高频超声在同部位上观察双侧坐骨神经的声像图变化。结果坐骨神经损伤后,在不同阶段,高频超声均可观察到相应变化图像改变与神经损伤后退变、再生及肢体功能在动态变化上相一致。结论高频超声可实时准确反映神经退变和再生的过程,为诊断外周神经损伤提供新方法,对临床判断和预后提供客观依据。
Objective To evaulate the clinical value of high-frequency ultrasonography on observing the acute crush injury of sciatic nerve in rabbits. Methods A total of 16 rabbits were randomly divided into four groups according to different observation time points. Models of acute crush injury of sciatic nerve in rabbits were established and observed by high-frequency ultrasonography 1,2,4 and 8 weeks respectively after damage. The internal radius of bilateral sciatic nerves were measured on the same levels. Results The echoism and internal radius of sciatic nerves was changed after the acute crush injury.The change was consistent to the dynamic change of the degeneration and regeneration of nerve and the function of limbs after damage. Conclusion High-frequency ultrasonography can reflect the course of nerve degeneration and regeneration correspondendy in real time. It provides a new morphological diagnostic approach for peripheral nerve damage.
