Introduction
An arteriovenous (AV) fistula connects an artery to a vein to create a strong vein for repeated hemodialysis needle access. This page explains what it is and why—not the detailed creation/surgery step pages.
Fistula does not cure kidney disease; it is dialysis access. Educational summary—no instant-use or cost guarantee.
Why it is done / when it is considered
What Is an AV Fistula and Why Is It Done? is commonly discussed in situations such as:
- Planning regular hemodialysis for chronic kidney disease
- Reduce infection/stenosis risk of long-term catheters
- Create access early before dialysis starts when ESRD approaches
- New access site when prior access fails
How the procedure is done
- Vascular mapping then surgical artery–vein anastomosis in arm
- Maturation takes weeks to months before dialysis needles
- AV graft or temporary catheter if veins unsuitable
- Joint nephrology–vascular surgeon planning
Preparation
- Protect chosen arm from BP needles/IVs beforehand
- Review mapping and kidney function trend
- Control diabetes, blood pressure, blood thinners
- Understand fistula vs graft vs catheter alternatives
Risks and possible complications
Risks differ by procedure. Your age, other illnesses, and anaesthesia plan change the picture—your care team will explain what applies to you.
- Failure to mature, thrombosis, stenosis
- Steal syndrome, swelling, aneurysm
- Infection/bleeding—uncommon but possible
- Later intervention or new access may be needed
Recovery
- Arm care and gentle exercises as taught
- Learn to feel thrill daily
- Nephrologist sets dialysis start—not immediate after surgery
Aftercare and follow-up
- Urgent care if thrill stops, hand cold/painful, or fever
- No BP cuff/watch/tight pressure on fistula arm
- Regular access surveillance
- Only trained staff should cannulate
Frequently asked questions
Different from fistula surgery guide pages?
Here definition and why; other pages detail operation steps and care.
Needed for peritoneal dialysis?
Usually no for PD; may discuss if future hemodialysis planned.
Can catheter stay forever?
Catheters are often temporary; fistula/graft preferred long term.
