Unrecognized vascular variation leading to failure of arteriovenous fistula cre...

AIMS OF THE STUDY: To describe the importance of preoperative venous and arterial mapping before choosing the best arteriovenous fistula (AVF) according to the National Kidney Foundation Dialysis Outcomes Quality Initiative (NKF-DOQI) guidelines. METHODS: We describe a case of a successful arteriovenous graft (AVG) creation after the failure of two AVF and a AVG without vascular mapping conducted before the su...

Value of color doppler ultrasound: parameters for proximal vascular access patency

Background: Color Doppler Ultrasound (CDU) is essential for vascular mapping in vascular access planning/creation. The aims of this study was to evaluate which anatomical and physiological variables of the artery and the vein, measured by CDU, were associated with higher patency at one year follow-up in brachiocephalic (BC) and brachiobasilic (BB) primary AV fistula (AVF). Materials and Methods: Retrospective o...

Upper limb arterial hemodynamics in high brachial artery bifurcation by color d...

Background: High bifurcation of the brachial artery is a common anatomic variant, with a prevalence of 12-20% and a challenging Doppler identification. This variant may have hemodynamic implications and compromise the success of a native arteriovenous fistula (AVF). The aim of this study is to compare the hemodynamic characteristics of the upper limb arterial axis based on the location of the brachial bifurcati...
