Hemodialysis Fistula
Specialized vascular access for safe, durable and effective dialysis treatment
What is it?
An arteriovenous fistula is a surgical connection between an artery and a vein, created to provide high-quality vascular access for hemodialysis treatments. It is the most recommended and durable type of access.
Gold Standard
The fistula is the preferred access due to its durability and lower risk of complications
Maturation Time
Requires 6-12 weeks to mature before use, but can last many years
Types of Vascular Access
Three main options for hemodialysis access, each with specific characteristics
Arteriovenous Fistula
Direct connection between artery and vein
- Most durable (years)
- Lower risk of infection
- Better blood flow
Vascular Graft
Synthetic tube connecting artery and vein
- Available in 2-3 weeks
- For inadequate vessels
- Higher risk of clots
Central Catheter
Tube inserted into large vein
- Immediate use
- Temporary solution
- Higher risk of infection
Advantages of Fistula
Why arteriovenous fistula is the preferred access for hemodialysis
Longer Duration
Can function for many years with proper care
Fewer Infections
10 times lower risk than other accesses
Better Flow
200-350 mL/min effective blood flow
Lower Mortality
Associated with better health outcomes
More Reliable
Excellent durability and lower failure rate
No Foreign Materials
Uses your own vessels, no foreign bodies
Creation Process
A specialized surgical procedure with careful follow-up
Initial Evaluation
Vascular mapping to identify the best blood vessels for connection
Outpatient Surgery
1-2 hour procedure under local or regional anesthesia, usually on the arm
Maturation (6-12 weeks)
The vein widens and strengthens until reaching 6mm diameter and 600 mL/min flow
Ready for Use
Final evaluation confirms it meets the "Rule of 6s" to start dialysis
Rule of 6s: 6 weeks of maturation, 6mm diameter, 600 mL/min flow, 6cm length for cannulation, less than 6mm depth.
Daily Care
How to keep your fistula functioning optimally
Daily Verification
- Feel the "thrill" (vibration) several times a day
- Listen to the "bruit" (flow sound) with stethoscope
- Confirm constant flow without changes
Hygiene and Protection
- Wash with antibacterial soap before dialysis
- Avoid tight clothing over the fistula
- Don't sleep on the fistula arm
Important Restrictions
- DO NOT take blood pressure on fistula arm
- DO NOT draw blood from the fistula arm
- DO NOT wear watch or tight jewelry
Strengthening Exercise
- Ball exercises to strengthen the vein
- Improves development during maturation
- Consult specific routine with your doctor
Warning Signs
Seek immediate medical attention if you experience any of these symptoms
Thrombosis
Absence of vibration or sound
Infection
Redness, warmth, pus or fever
Aneurysm
Excessive swelling or bulging
Steal Syndrome
Cold, pale hand, pain or weakness
Complication Statistics
Thrombosis is the most common complication. Infections occur in 20% of fistulas (10 times less than grafts). Steal syndrome affects 1.8% of fistulas. Early detection significantly improves outcomes.
