目的：探讨高频超声在正常成人坐骨神经检查中的应用价值.
方法：应用高频超声检查60例共120条正常成人坐骨神经,男28例,女32例;年龄19～38岁,平均23.8岁.男女之间年龄、身高及体重差异均无统计学意义.采用横断扫查及纵断扫查,必要时结合宽景成像.在臀线处、股后部中段、腘窝上缘分别测量坐骨神经横截面积,并在每个横断面上观察坐骨神经与周围肌群关系;在臀部显示坐骨神经横断面后探头旋转90°,显示坐骨神经长轴,沿长轴从上到下纵切,结合宽景成像可以显示坐骨神经纵轴及与周围肌群关系.以男女分组和左右分组,分别求得臀线处中部、股后部中段、腘窝上缘处各组坐骨神经横截面积的均数和标准差,进行统计学分析.
结果：高频超声对本组60例受检者120条股部坐骨神经均可清晰显示,但对臀部坐骨神经显示率较低,约为31.4%(21/66).坐骨神经纵切面表现为条带状等回声或偏强回声,内可见数条平行偏强回声线,横断面呈边缘清楚的筛网状等回声或略强回声,可呈卵圆形、梯形、三角形及不规则形等,肌肉收缩时可见坐骨神经被动运动且形态可发生改变.28例男性56支坐骨神经与32例女性64支坐骨神经臀线处、股后部中段及腘窝上缘测得的横截面积,经统计学分析,男女之间对比差异有统计学意义;而左右侧对比差异无统计学意义.
结论：高频超声可作为坐骨神经首选的影像检查方法. |

Abstract:
Objective:To explore the application value of the high-frequency ultrasound examination of the normal adult sciatic nerve.
Methods:The high frequency ultrasound was used to examine 60 cases,a total of 120 normal adult sciatic nerve(28 males and 32 females,ranging in age from 19 to 38 years old,averaged 23.8 years old). The age between men and women,height and weight showed no significant difference. The cross-sectional scanning and longitudinal scanning,if necessary,Panoramic Imaging were conducted. The cross section area of sciatic nerve was measured at the hip line,the middle of the thigh,the upper edge of the popliteal fossa,and the relationship between the sciatic nerve and surrounding muscle groups was observed in each cross-section. Probe was rotated 90 degree to display the long axis of sciatic nerve,to get the longitudinal section along the long axis from top to bottom. So the sciatic nerve in the vertical axis and the surrounding muscles was displayed by above method combined with Panoramic Imaging. The data of cross-sectional area of sciatic nerve were obtained at the central of hip line,the middle of the thigh,the edge of the popliteal fossa,and then were divided into different groups by gender and sides to do statistical analysis.
Results:The sciatic nerve in thigh can be clearly displayed by high-frequency ultrasound in this group of 60 people with 120 nerves,but low display rate of sciatic nerve in hip,approximately 31.4% (21/66). The longitudinal section of the sciatic nerve displayed as the banded isoechoic or slightly hyperechoic,parallel partial hyperechoic line could be seen in it; in the cross-section,it showed a clear edge of the sieve-like isoechoic or slightly hyperechoic,which could be oval,trapezoidal,triangular and irregular in shape; the sciatic nerve had visible passive movement and shape change when muscle contracted. There were statistically significant differences of cross-sectional area of sciatic nerves at the hip line,the middle of thigh and edge of the popliteal fossa between 56 sciatic nerves in 28 males and 64 sciatic nerves in 32 females (P < 0.05);but there were no significant differences between left and right sides(P > 0.05).
Conclusion:High frequency ultrasound can be used as the first choice of the sciatic nerve when an imaging method preferred. |
