| 目的 探讨高频超声对腕管段正中血管神经束解剖变异的检测价值及其在腕管综合征诊治中的意义。方法 对500位健康志愿者的1000只手腕部腕管结构及前臂进行高频超声检查。发现并记录腕管段正中神经分叉、永存正中动脉、永存正中静脉的位置、分布,测量腕管段永存正中动脉、永存正中静脉的直径,在豌豆骨水平测量正中神经分叉两侧支的横截面积。结果 ?正中神经分叉阳性者共41例(4.1%),且全部分为两支。在豌豆骨水平测量横截面积,所有正中神经分叉者,桡侧支横截面积均大于尺侧支；27例单侧正中神经分叉者,两侧支横截面积之和与对侧同一位置横截面积比较无明显差异。?永存正中动脉阳性者共20例(2%),永存正中静脉阳性者13例(1.3%)。?在41例正中神经分叉、20例永存正中动脉阳性者中,正中神经分叉合并永存正中动脉者16例,分别占39%、80%。结论 高频超声可以清晰显示腕管段正中血管神经束的解剖变异,识别这些变异,有助于全面准确诊断腕管综合征,合理选择术式及手术入路,避免损伤神经、血管及解压不完全等并发症。 |

| Abstract: |
| Objective To investigate the value of high resolution ultrasonography in demonstrating the anatomical variations of the median vessels and median nerve in the carpal tunnel and it’s clinical significance. Methods A total of 1000 hands of 500 healthy volunteers were included in the study. The location and shape of the bifid median nerve, persistent median artery and persistent median vein were recorded. The diameter of the persistent median artery and persistent median vein in the carpal tunnel were measured. The cross-sectional area of the |
