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