Fistulagrams

Fistulagrams

A fistulagram is a specialized imaging procedure used to evaluate dialysis access sites, such as arteriovenous fistulas (AVF) or grafts (AVG). This test helps your vascular team identify blockages, narrowing, or other issues that may affect blood flow during dialysis.

How a Fistulagram Works

• A small catheter is inserted into your fistula or graft.
• Contrast dye is injected to make the blood vessels visible on X-ray or fluoroscopy.
• The images allow the vascular specialist to detect narrowing, clots, or other problems.
• Based on the results, your doctor can recommend timely treatments to maintain safe and effective dialysis.

Why a Fistulagram May Be Recommended

• To assess the function of your AVF or AVG for dialysis.
• If there are signs of reduced blood flow or complications at your access site.
• To plan interventions such as angioplasty or stenting if blockages are detected.
• To help ensure your dialysis treatments remain safe, effective, and comfortable.

Benefits of a Fistulagram

• Detects problems early before they affect dialysis.
• Helps your healthcare team maintain proper blood flow to your access site.
• Can guide minimally invasive interventions to restore function.
• Supports safe, consistent, and effective dialysis treatments.

What to Expect During and After the Procedure

• Usually performed in a hospital or outpatient vascular center.
• Local anesthesia is typically used to minimize discomfort.
• The procedure is relatively quick, often under an hour.
• Patients can usually resume normal activities shortly after, depending on their care plan.
• Follow-up appointments ensure your access site is functioning properly.

Safety & Recovery Tips

• Follow all instructions from your healthcare team.
• Keep the access site clean and monitor for swelling, redness, or bleeding.
• Report any changes in your access site immediately to your doctor.
• Maintain healthy lifestyle habits to support vascular health and dialysis effectiveness.
