“…However, when a steal is present, blood from the ulnar artery is shunted to the radial artery and the fistula. This can be corrected by ligating the distal radial artery or creating an end to side (artery to vein) fistula.3 3 The use of an AVG is reserved for those patients in whom an internal AVF is not possible or has failed. There are many materials available for the construction of an AVG.…”

Hemodialysis is essential in the management of end stage renal disease patients. Forty-eight contrast examinations of hemodialysis vascular access devices were reviewed. Venous fistulography is the method of choice for the evaluation of these devices. Only 12 patients in this series required arteriography and 6 of them had a lower extremity access device. The most common complications included venous stenoses, venous or graft aneurysms, pseudoaneurysms and venous or graft thrombosis. Pseudointimal proliferation resulting in graft stenosis was also observed.

Spiral computed tomographic angiography (CTA), a new noninvasive imaging technique, was used to study 10 arteriovenous fistulas (AVF) in 9 hemodialysis patients. Digital subtraction angiography (DSA) was also performed as a gold standard for comparison. AVF stenosis was graded by a four-point scale: grade 0, well patency of supplying artery, anastomosis and drainage vein; grade 1, <50% stenosis; grade 2, 50–70% stenosis; grade 3, 70–99% stenosis, and grade 4, total occlusion. We found CTA correlated closely to DSA in detecting both stenosis and dilatation of AVF and it spared all the shortcomings of DSA. CTA has the potential to be alternative for imaging of dialysis fistulas. Further studies will be performed to specify the role of CTA images in the assessment of the hemodialysis vascular access.

“…Images of the complete venous outflow were obtained with repeated manual injection of 5-10 mL of contrast material. Images of the access and its inflow tract were obtained either with manual compression or with flow interruption through a cuff of the venous outflow (18). In cases where the arterial inflow could not be depicted adequately, an attempt was made to advance a guidewire from the venous puncture site into the feeding artery.…”
