高频超声检查在外周神经医源性损伤诊断中的应用

Application of high-resolution sonography for diagnosis of iatrogenic peripheral nerve injury

目的:探讨高频超声对医源性外周神经损伤的诊断价值。方法:总结经肌电图及手术证实的12例医源性外周神经损伤患者的高频超声声像图特征。结果:12例患者均有不同种类的手术史,并出现不同的神经损伤临床表现,包括6例桡神经受压、5例尺神经受压、1例腓总神经受压。高频超声不仅可清晰显示神经受压及其两端增粗的程度,也能显示压迫神经的内固定及部分瘢痕组织。结论:高频超声能有效诊断外周神经医源性损伤,为临床治疗提供影像学依据。

Objective： To explore the ultrasound diagnostic value of iatrogenic peripheral nerve injury. Methods：The ultrasonographic features of 12 cases of iatrogenic peripheral nerve injury confirmed by electromyogram and surgery were summarized. Results： 12 patients had different types of surgery,patients appeared different clinical manifestations of nerve injuries,including 6 cases of radial nerve compression,5 cases of ulnar nerve compression,1 case of total nerve compression. High frequency ultrasound could clearly show not only nerve compression and the degree of enlargement of the ends of the compressed nerve,but also the internal fixation and some scar tissue.Conclusion： High frequency ultrasound is effective in the diagnosis of iatrogenic peripheral nerve injury,providing imaging basis for clinical treatment.
