摘　　要：目的:探讨彩色多普勒超声在血液透析患者血流量减低并发症诊断中的作用。方法:对57例血液透析患者动静脉瘘进行超声检查,二维超声观察桡动脉、头静脉及吻合口有无扩张及狭窄,管腔内有无血栓、斑块,血管周围有无血肿等情况,再用多普勒超声观察血管内血流方向、血流充盈及血流速度。结果:57例动静脉内瘘血液透析患者中,头静脉血栓18例(32%),头静脉管腔狭窄14例(25%),头静脉瘤样扩张9例(16%),桡动脉硬化8例(14%),吻合口狭窄6例(10%),造瘘血管旁软组织内血肿2例(3%)。结论:动静脉内瘘患者发生血流量减低时,应用彩色多普勒超声对造瘘血管进观察,能够及时发现并发症,指导临床干预治疗,保证患者透析质量。Objective：To explore the value of color Doppler ultrasound in diagnosis of low blood flow of arteriovenous fistula complication in hemodialysis patients.Methods：Fifty-seven cases were examined and analyzed by color Doppler ultrasound.It was important to observe conformation of fistula and blood vessel and examine changes on hemodynamics.Results：Among these cases,cephalic vein thrombosis in 18 cases （32%）,cephalic vein stenosis in 14 cases（25%）,cephalie vein aneurysm expansion in 9 cases（16%）,radial artery atherosclerotic in 8 cases （14%） ,anastomotic fistula stenosis in 6 cases （10%）,hematoma in 2 cases （3%）.Conclusion： Color Doppler ultrasound can clearly show the position ,pathway ,lumen and blood flow dynamics of low blood flow of arteriovenous fistula in hemodialysis patients and detect the complications for clinical reference.
