周围神经压迫综合征是单一周围神经的局灶性病变,即为单神经病或单发性单神经病,通常是因创伤、局部压迫、卡压等造成~[1]。目前,神经电生理仍是周围神经损伤诊断及病因分类的主要检查方法~[2]。但随着高分辨率超声技术的发展,目前已经能够通过超声技术获得清晰详细的外周神经结构图像。神经超声主要用于评估神经横截面积、沿神经走向的横截面积变化、神经内部回声变化、神经内部血流变化及 Peripheral nerve compression syndrome is a focal peripheral nerve disease, which is single neuropathy or solitary mononeuropathy, usually due to trauma, local oppression, compression caused by ~ [1]. At present, neuroelectrophysiology is still the main diagnostic method of peripheral nerve injury and etiological classification [2]. However, with the development of high-resolution ultrasound technology, it is now possible to obtain clear and detailed images of peripheral nerve structures by means of ultrasound. Nerve ultrasound is mainly used to assess the nerve cross-sectional area, cross-sectional area along the neural path changes, changes in nerve internal echo, blood flow inside the nerve and
