Fistulogram

A fistulogram uses fluoroscopy, a real-time x-ray using x-ray dye, that checks for any abnormalities within the blood flow that may interfere with other medical treatments. It produces images of any abnormal passage within the body called a fistula. Fistulas routinely have narrowings that reduce flow rates during dialysis. Fistulograms are necessary to detect any blockages that may interfere with dialysis treatments. These may lead the doctor to perform an angioplasty sometimes with a stent at the end. Many times, routine surveillance is needed for patients with recurring problems, which can be managed by Interventional Radiologists and Nephrologists.
