Using sterile technique, a radiologist introduces a small needle into the dialysis graft/fistula just
below the skin surface. Following the placement of the needle, pictures are taken while injecting
contrast material through the needle and into the arteriovenous system. This injection allows for
the complete evaluation of the involved structures. Once the initial evaluation is complete, the
radiologist may decide that some area/s may need to be fixed in order to improve or restore the
functionality of the dialysis access. This may include using various catheters, wires, and small
balloons in order to open the vessels within the arteriovenous system. It is during this time that
local anesthetic and in some cases mild sedation may be given under the direction of the performing
physician in order to keep the patient comfortable. For many dialysis patients the shuntogram is a
common procedure that is used to evaluate and maintain the dialysis access. In normal
circumstances, once the shuntogram has been complete, the involved dialysis access sight may be
used immediately for dialysis. If sedation had been given for the procedure the patient may need to
stay for short-term observation in order to ensure it is safe for the patient to leave the facility.
