摘　　要：【目的】探讨高频超声在判断上肢神经吻合术后早期再生中的作用。【方法】采用彩色多普勒超声诊断仪对11例患者共15条神经在缝合术后早期进行超声检测,记录神经吻合口声像特征,并与电生理检查进行比较。【结果】超声检查显示15条神经中,11条神经吻合口可见清晰或模糊的神经束自吻合口近端向远端延伸,神经外膜延续性较好;另4条神经吻合口未见神经束通过。根据声像学特征将上述神经束通过吻合口情况与术中电生理检查结果比较,超声诊断符合率为86.6%。【结论】超声检查具有直观、无创、价廉、操作简单等优点,对神经缝合术后早期吻合口神经束通过情况有较高分辨率,可为临床治疗方式的选择提供帮助。[Objective] To evaluate the diagnositic value of high-resolution ultrasonography in determining early regeneration of repaired nerve of upper lime. [Methods] Total of 15 nerves in 11 patients were studied.The specific image of suture site was recorded, and compared with intraoperative findings and electromyography （EMG）. [ Results] We have found nerve bundle extending from proximal to distal of the suture sites in 11 cases, the other 4 were not found.According to the sonogram image, the repair sites covered 2 status. Correlating with intraoperative EMG, the accuracy of ultrasonography was 86.6%. [ Conclusions] Ultrasonography has decent accuracy in evaluating the status of nerve repaired early period after the operation, and mayhelp to choose the right therapy.
