Objective: To analyze the application value of color Doppler ultrasound in the evaluation of autologous arteriovenous fistula (AVF) complications in long-term dialysis patients. Methods: From March 2016 to February 2018, 80 patients with long-term autologous arteriovenous fistula dialysis were treated in our hospital. The anatomy and hemodynamics of arteriovenous fistula, cephalic vein and radial artery were detected. The indexes of blood vessel diameter, thrombus, stenosis, flow rate, flow rate, etc. were recorded, and the function of internal hemorrhoids was evaluated to compare with the function of clinical dialysis. RESULTS: Ultrasound examination showed that 60 of 80 patients with long-term dialysis had normal arteriovenous fistula function, 7 had thrombosis, 9 had stenosis, 2 had pseudoaneurysm, 1 case had stolen blood syndrome and 1 patient had heart failure. The blood flow of the fistula, the diameter of the cephalic vein and adjacent radial artery inner diameter were significantly lower than those in the normal fistula (P<0.05). Conclusion: Color Doppler ultrasound can effectively detect the specific pathway of autologous arteriovenous fistula in long-term dialysis patients, accurately diagnose various complications, find out the causes of low blood flow, and provide important reference for clinical treatment.
