“…It is suggested that [ 25 ] the incidence of stenosis was great when the flow rate was <650 mL/min. It is also reported that [ 11 ] the incidence of thrombosis was great when the flow rate was <500 mL/min or decrease >25%. The cut-off point was slightly lower in this study, probably due to the overall lower AVF flow of Chinese patients.…”

“…With proper monitor, thrombosis and stenosis can be early detected and timely treated, extending the life of fistula and increasing patient's survival rate. [ 11 ] Color Doppler ultrasound is used widely in clinic [ 12 – 15 ] and is recommended as the best way to monitor AVF due to its noninvasiveness, no radioactive damage, repeated usage, low price, and real-time access to AVF anatomical and hemodynamic information. [ 16 , 17 ] The brachial artery is straighter with larger diameter and the blood flow is more accurately measured by Doppler ultrasound.…”

This study aims to evaluate the application of color Doppler ultrasound in monitoring the complications of autologous arteriovenous fistula in hemodialysis patients.Patients with maintenance hemodialysis who underwent autologous arteriovenous fistula were enrolled in this cross-sectional study. Ultrasound was used to detect fistula complications (stenosis and thrombosis), brachial artery diameter, and hemodynamic parameters. The ultrasound parameters were analyzed and screened to identify the most important indicator for monitoring complications.In all, 89 patients were included. Ultrasound showed 72 cases (80.90%) had normal fistula structure, and 17 cases (19.10%) had complications. The diameter, time-averaged mean velocity, flow volume, and diastolic peak velocity of brachial artery in complication group were significantly lower than those of noncomplication group (P < .05). The brachial artery pulsatility index and resistance index of complication group were significantly higher than those of noncomplication group (P < .05). There was no significant difference in peak flow velocity between complication and noncomplication group (P > .05). Indicators showed statistical significance were grouped based on quantiles. The incidence of complications was higher when the brachial artery diameter was ≤5.40 mm, or brachial artery flow was ≤460 mL/ min, or brachial artery pulsatility index was >1.04, or brachial artery resistance index was >0.60.Ultrasound monitoring of brachial artery diameter and hemodynamic parameters can help early detection of fistula complications. When the brachial artery diameter was ≤5.40 mm, or brachial artery flow was ≤460 mL/min, or brachial artery pulsatility index was >1.04, or brachial artery resistance index >0.60, stenosis or thrombosis should be checked to prevent fistula failure.

“…Finally, 9 trials reporting outcomes comprising 990 patients (422 women and 568 men) were included in the analysis. Two studies were conducted in the United States, [ 10 , 12 ] 1 in Canada, [ 13 ] 1 in Australia, [ 15 ] 1 in Brazil, [ 16 ] 1 in Spain, [ 32 ] 2 in Italy, [ 14 , 33 ] and 1 in the Netherlands. [ 11 ] The number of patients ranged from 58 to 196 patients in each study.…”

“…In addition, the study by Sands et al [ 10 ] included both patients with AVFs and AVGs. Therefore, 6 studies consisted of patients with AVFs, [ 10 , 14 – 16 , 32 , 33 ] and 5 studies comprised patients with AVGs. [ 10 – 13 ]…”

“…All studies used clinical assessment every dialysis treatment in the access flow surveillance and control groups. The method of access flow measurement was ultrasound dilution in 8 studies [ 10 – 15 , 32 , 33 ] and ultrasound duplex in 1 study. [ 16 ] The monitoring methods in the control group were dynamic VP [ 11 , 13 , 34 ] and static pressure.…”
