AV fistulas and grafts provide reliable, long-term dialysis access by connecting an artery to a vein. At Atrium Vascular Associates, board-certified vascular and endovascular surgeon Dr. Sydney Wong carefully evaluates your anatomy and health to recommend the safest option.
Improve Dialysis Access and
Blood Flow
AV fistulas and AV grafts are two proven surgical methods for creating reliable access for hemodialysis. Both provide repeated access to your bloodstream while maintaining blood circulation for dialysis.
Arteriovenous (AV) Fistula Creation
An arteriovenous fistula is created by connecting one of your arteries directly to a nearby vein. Over time, this increases blood flow and strengthens the vein, making it suitable for dialysis. AV fistulas are the most durable option, and involve a lower risk of infection and thrombosis.
Arteriovenous (AV) Graft Placement
An arteriovenous graft uses a soft synthetic tube to connect an artery to a vein when native vessels are not suitable for a fistula. The graft provides a reliable dialysis access that can often be used sooner than a fistula. However, grafts may require more maintenance over time.
Why Do You Need AV Fistulas & Grafts?
AV fistulas and grafts are recommended after testing and evaluation confirm advanced or permanent kidney failure requiring hemodialysis. Once bloodwork and kidney function tests indicate that dialysis is necessary, a safe, reliable method to access your bloodstream becomes essential. These procedures support long-term treatment by allowing dialysis to be performed effectively and repeatedly. You may need AV fistulas & grafts if:
- You require long-term or permanent hemodialysis
- You have been diagnosed with end-stage kidney disease
- You need a more reliable option than temporary dialysis catheters
- You have veins that must be evaluated for safe dialysis access
- You are preparing in advance for future dialysis treatment
Why Choose Dr. Sydney Wong?
Dr. Sydney Wong is a board-certified vascular and endovascular surgeon with extensive experience creating and maintaining dialysis access. He carefully evaluates your blood vessels to determine whether an AV fistula or graft is most appropriate, then performs the procedure himself and remains involved through ongoing follow-ups, helping ensure your access continues to function reliably for dialysis.
What to Expect During AV Fistulas & Grafts?
On the day of surgery, your arm is cleaned and numbed. Dr. Wong then creates a direct connection between an artery and a vein or places a soft synthetic graft to establish blood flow. After the procedure, your arm is monitored to ensure the access is working properly. You may feel a vibration, called a thrill, which signals healthy blood flow. You’ll receive clear instructions on arm care and activity limitations to help protect your dialysis access as it heals.
Benefits of AV Fistulas & Grafts
AV fistulas and grafts provide safe, dependable access for ongoing dialysis while reducing many of the risks associated with temporary catheters. When planned and created carefully, they offer several important advantages, including:
- Reliable, repeatable access for hemodialysis
- Improved blood flow to support effective treatments
- Lower infection risk compared to long-term catheters
- Greater durability for ongoing dialysis needs
- Better comfort and mobility during daily activities
AV Fistulas & Grafts FAQs
How Long Does It Take for an AV Fistula to Be Ready for Use?
Most AV fistulas require several weeks or months to mature. During this time, the vein gradually enlarges and strengthens. You may be asked to perform simple hand or arm exercises to support this process while your access is monitored closely.
Can an AV Graft Be Used Sooner Than a Fistula?
Yes. AV grafts typically require less healing time and can often be used within a few weeks. This makes grafts a practical option if dialysis must begin sooner or if your vein anatomy limits fistula creation, while still providing dependable long-term access.
