Effect of Ultrasonography on Blood Flow in Hemodialysis Patients with Artificial Arteriovenous Fistula
Objective:To explore the effect of ultrasonography on blood flow in hemodialysis patients with artificial arteriovenous fistula.Methods:A total of 160 hemodialysis patients admitted to the our hospital from January 2021 to January 2023 were selected,and were divided into the observation group and the control group,with 80 cases in each group.Contrast-enhanced radiography and color Doppler ultrasonography were used to examine artificial arteriovenous fistulas in these patients,and the effect of ultrasound on blood flow examination in hemodialysis patients with artificial arteriovenous fistulas was analyzed.Results:The results of angiography showed that 59 cases had normal arteriovenous fistula function and 21 cases had abnormal arteriovenous fistula function,including 10 cases of thrombus,7 cases of stenosis,3 cases of phlebectasia and 1 case of pseudoaneurysm.The results of color Doppler ultrasonography showed that the diagnostic accuracy was 100%in 10 cases of thrombus,71.43%in 5 cases of stenosis,66.67%in 2 cases of aneurysmal dilatation of cephalic vein and 100%in 1 case of pseudoaneurysm.Conclusion:Ultrasonography can accurately reflect the blood flow status in hemodialysis patients with artificial arteriovenous fistula and has a high diagnostic rate for complications such as thrombus and stenosis,which can provide good diagnostic references for clinical intervention.
