摘　　要：目的探讨彩色多普勒超声诊断外周动静脉瘘的临床价值。方法回顾性分析21例经手术和(或)造影证实的外周动静脉瘘患者的术前二维、彩色及脉冲多普勒超声图像。结果彩色多普勒超声定位诊断动静脉瘘的准确率为91.67%,定性诊断准确率为100%。瘘口和其相关动静脉的血流动力学变化具有特异性,瘘口处动脉进入静脉的高速、低阻、双期、单向血流是动静脉瘘的血流频谱特征。结论彩色多普勒超声对外周动静脉瘘的定位、定性诊断价值大,结合相关参数综合分析对临床诊断和治疗具有重要意义。Objective To explore the clinical value of color Doppler ultrasound in diagnosis of arteriovenous fistula in peripheral vessels.Methods Twenty-one patients with arteriovenous fistula in peripheral vessels were confirmed clinically,and images of two-dimensional ultrasound,color Doppler ultrasound and pulse Doppler ultrasound before operation were analyzed retrospectively.Results The accuracy rate of qualitative diagnosis of color Doppler ultrasound was 100%,while of localization diagnosis was 91.67%.Orificium fistulae and hemodynamics of arterovenous fistula in peripheral vessels had typical characteristics.High velocity,low resistance index,continue flow,one direction of flow in arteriovenous fistula were the features of Doppler image.Conclusion Color Doppler ultrasound plays a significant role in diagnosis of arteriovenous fistula in peripheral vessels before operation.
