Thirteen of 54 (24%) had mild central venous stenosis (stenosis &lt;50% diameter with or without collateral branch), 7\/54 (13%) had upper arm vein system occlusion or stenosis, another one had anastomotic stenosis. There were no differences in fistula flow dynamics between those with venous abnormalities and those without such as blood flow rate, venous pressures, brachial arterial velocity, and brachial arterial flow rate. We also observed no significant differences in other variables between these two groups (including BMI, hemoglobin, albumin, gender, primary disease, URR, spKt\/V P\u2009&gt;\u20090.05).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The frequency of venous lesion is not low in hemodialysis patients with a well-functioning AVF.
