目的:探讨高频彩色多普勒超声诊断上肢神经疾病的临床价值.方法:采用高频彩色多普勒超声对32例上肢神经疾病患者进行诊断检查,通过观察上肢神经的连续性、神经外膜、神经束和周围组织,以及与神经相关联的肿块及其相关性,确定神经疾病的类型和部位,分析其声像图特征,并与健侧进行对比.结果:神经鞘瘤患者14例,均为单发,图像特征以椭圆形低回声为主,界清,有包膜.神经纤维瘤患者6例,其中5例单发,为低回声,内部回声尚均,梭形为主,两端与神经相连;另1例多发,呈串珠状.尺神经炎患者3例,局部神经增粗,回声减低,横断面呈低回声,"筛网状"结构消失,CDFI血流信号较丰富.外伤患者9例,局部神经受压、形态失常,且其周围可见不规则异常回声区.结论:不同上肢神经疾病的声像图各有其特征性表现,高频彩色多普勒超声可为临床诊治提供依据.%Objective:To explore the clinical value of high frequency color Doppler ultrasound in the diagnosis of upper limb nerve disease.Methods:The inspection of 32 patients with upper limb nerve disease was performed by high frequency color Doppler ultrasound.Through observing the upper limb nerve continuity, epineurium, nerve bundle, surrounding tissues, the nerve-associated mass and their relevance, the type and location of neurological diseases were confirmed, and the ultrasonographic features were analyzed and compared with those of the healthy side.Results:Fourteen cases showed single schwannoma, whose image characteristics were priority to elliptic low echo, clear boundary, the envelope.Six cases showed neurofibromatosis;among them, 5 cases with single neurofibroma showing low echo, internal uniform, fusiform shape, and the ends connected with the nerves;other 1 case with multiple and beaded neurofibroma.Three cases showed ulnar neuritis with local nerve thickening, echo reduction, hypoechoic cross-section, "screen mesh shape" structure disappearing, and abundant blood flow signals on CDFI.Nine cases showed traumatic nerve injury, whose local nerve was compressed and morphologically abnormal, with irregular abnormal echo around region.Conclusions:The different upper limb nerve diseases have different characteristic ultrasonography, and high frequency color Doppler ultrasound may provide the preferred image basis for clinical diagnosis and treatment.
