Dialysis Access Management
Reliable vascular access is essential for patients on hemodialysis. At IYA Medical, our interventional radiologists specialize in creating, maintaining, and restoring dialysis access to ensure uninterrupted treatment for kidney disease patients.
Understanding Dialysis Access
Hemodialysis requires access to the bloodstream that can handle the high blood flow rates needed for effective treatment. There are three main types of dialysis access:
Arteriovenous Fistula (AV Fistula)
Created surgically by connecting an artery to a vein, usually in the arm. Considered the "gold standard" for dialysis access due to longevity and lower infection rates.
Arteriovenous Graft (AV Graft)
A synthetic tube connecting an artery to a vein when a fistula isn't possible. Can be used sooner than a fistula but may have more complications.
Dialysis Catheter
A tube placed in a large vein, usually in the neck, chest, or groin. Used for immediate or temporary access but carries higher infection risk.
Interventional Radiology Services
Fistulagram (Dialysis Access Imaging)
Using X-ray and contrast dye, we can evaluate your dialysis access to identify problems like narrowing (stenosis) or clotting.
Angioplasty and Stenting
When stenosis (narrowing) is identified:
- A balloon catheter is used to open the narrowed area
- If needed, a stent may be placed to keep the vessel open
- Restores adequate blood flow for dialysis
Thrombectomy and Thrombolysis
When a fistula or graft becomes clotted:
- Mechanical devices or clot-dissolving medications remove the clot
- Underlying narrowing is treated to prevent re-clotting
- Can often restore function the same day
Catheter Placement and Exchange
When a catheter is needed:
- Tunneled catheters for longer-term use
- Non-tunneled catheters for emergency access
- Catheter exchange when problems occur
Signs Your Access May Need Attention
- Swelling of the access arm
- Weak or absent pulse/thrill in the access
- Difficulty with needles during dialysis
- Prolonged bleeding after dialysis
- Poor dialysis clearance
- Signs of infection (redness, warmth, drainage)
Maintaining Your Access
Tips to protect your dialysis access:
- Keep the access clean and dry
- Feel for the thrill (vibration) daily
- Don't allow blood pressure checks or blood draws from the access arm
- Avoid sleeping on the access arm
- Don't wear tight clothing or jewelry over the access
- Report problems promptly
