摘　　要：目的：探讨高频超声在观测尿毒症患者人工动静脉造瘘血管中的应用价值。方法：采用二维及彩色多普勒超声对55例尿毒症血液透析患者的人工动静脉造瘘血管进行超声检查、分析。结果：高频超声检测出47例尿毒症患者瘘管内径4.5-7.4 mm,瘘管血流充盈好,呈＂五彩镶嵌＂血流,频谱呈高速低阻;3例瘘口狭窄;2例瘘口血栓形成;1例假性动脉瘤形成;2例血管瘤样扩张。结论：高频超声能观察血管内径及管腔内回声,实时动态分析血流动力学参数,及时发现并处理并发症,具有重要的临床应用价值。Objective： To evaluate the application value of high-frequency ultrasound in monitoring artificial arteria-venous fistulas in patients with uraemia. Methods： Fifty-five patients were examined and analyzed by CDFI and 2D. Results：Among 55 patients, 47 cases showed good filling state of the vessel, diameters of fistulas were 4.5~7.4 mm, fistulas had colorful mosaic blood with high velocity and low resistance index.3 cases with stenosis, 2 cases with thrombus ,1 case with false aneurysm and 2 cases with venous dilatation. Conclusion：High-frequency ultrasound plays an important role in observing the vessels diameters, echoes and real-time analyzing hemodynamic parameters, which is helpful to the detection and management of complications.
