“…For brachial artery RI, Koseoglu et al [ 27 ] showed that brachial artery RI (measured 3–4 cm above elbow) was a predictor of AVF failure. Moreno Sanchez et al [ 19 ] reported that stenosis and thrombosis could lead to increased RI in artery inflow. Our study was consistent with these studies, demonstrating that with abnormal AVF, brachial artery RI significantly increases.…”

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.

“…[ 18 ] There are no uniform ultrasound parameters for monitoring AVF. [ 7 , 19 ] Flow monitoring can reduce the incidence of thrombosis or stenosis. However, the extent of flow intervention in AVF is under debate.…”

“…In terms of RI values from the brachial artery site, we found 89% sensitivity and 88% specificity for 0.52 RI value to detect AVF dysfunction. Sánchez et al [ 17 ] showed that flow reductions together with RI elevations were associated with AVF dysfunction. But that study did not establish cut-off values of flow volume or resistive index because there were a small number of normal function AVFs in the study.…”

PurposeThe aim of this study was to evaluate the flow volume and resistive index parameters of the brachial artery in the functioning and dysfunctioning radiocephalic and brachiocephalic hemodialysis arteriovenous fistula (AVF).Methods82 patients were distributed into three groups according to their hemodialysis function - as normal function, decreased pump flow and increased venous pressure. Flow volumes and resistive indexes (RI) of the brachial artery of radiocephalic and brachiocephalic AVFs were measured by Doppler ultrasound. Flow parameters of the groups were compared.ResultsA statistically significant difference was found between the normal and decreased pump flow groups in terms of flow volume and resistive index values. 770 ml/min flow volume of the brachial artery has a 94% sensitivity and 84% specificity and 0.52 value of RI has an 89% sensitivity and 88% specificity in the the differentiation of normal and decreased pump flow groups.ConclusionDoppler parameters of the brachial artery such as flow volume and RI can provide valuable information about AVF function.

“…Las estenosis en el trayecto de fístulas arteriovenosas (FAV) para hemodiálisis (HD) son un problema muy prevalente. Se presentan de forma significativa hasta en el 42% de las FAV nativas (1,2). Existe una larga experiencia en su tratamiento mediante angioplastia percutánea, procedimiento que, sin embargo, implica unas necesidades no despreciables de aparataje, exposición a radiación y contraste intravenoso que no son beneficiosas para el paciente y hacen más compleja su realización.…”
