About Fistulagram

A fistulogram is a special x-ray procedure that identifies abnormalities in the blood flow through your dialysis access that may be interfering with your dialysis treatment. This minimally invasive x-ray procedure uses contrast (a dye) and can detect problems like clots or narrowing. The fistulogram reveals areas of narrowing, enlargement, or blockage within the veins and arteries of your AV fistula or graft.
