At Dialysis Management Santa Fe, we understand how important it is to keep your dialysis fistula open and functioning properly. A healthy fistula ensures adequate blood flow during hemodialysis treatments, helping prevent complications and supporting effective treatment.

Why Fistula Monitoring Is Important
Regular monitoring helps detect:
- Narrowing of the fistula (stenosis)
- Blood clots (thrombosis)
- Reduced blood flow
- Potential infections
- Other complications that may interfere with dialysis treatments
Early detection allows for timely intervention and helps maintain the long-term function of your fistula.
Color-Flow Doppler Ultrasound
A color-flow Doppler ultrasound is a specialized imaging test that evaluates blood flow through the fistula.
Benefits
- Measures blood flow rates
- Detects narrowing (stenosis)
- Identifies blood clots (thrombosis)
- Helps determine whether treatment is needed
Treatment Options
If stenosis is detected:
- The narrowed area can be mechanically dilated to restore blood flow.
If blood clots are found:
- Clots may be removed through minimally invasive procedures using either internal (transhepatic) or external (transcutaneous) access techniques.
Doppler Ultrasound Monitoring
Doppler ultrasound provides ongoing monitoring of blood flow through the fistula.
How It Helps
- Tracks changes in fistula performance
- Identifies reduced blood flow before serious complications occur
- Allows healthcare providers to determine when intervention is necessary
- May eliminate the need for more expensive imaging tests such as MRI or CT scans
Improving Blood Flow
In some cases, reduced blood flow may occur when dialysis treatments have been missed. Healthcare providers may recommend medications such as acetylcysteine to help improve flow when appropriate.
Recommended Monitoring Schedule
Dialysis Management Santa Fe recommends:
- Acoustic Doppler monitoring during hemodialysis treatments
- Color-flow Doppler ultrasound imaging at least once per week
Regular monitoring helps ensure:
- Adequate blood circulation
- Early detection of clot formation
- Proper fistula function
- Reduced risk of treatment interruptions

Signs of Fistula Problems
Stenosis (Narrowing)
A stenosis occurs when part of the fistula becomes narrowed, restricting blood flow.
Symptoms
- Reduced blood flow
- Pain during dialysis
- Swelling around the access site
Treatment
- Balloon angioplasty using an over-the-wire balloon catheter to widen the narrowed area
Thrombosis (Blood Clotting)
Thrombosis occurs when blood clots form within the fistula.
Symptoms
- Loss of blood flow
- Difficulty performing dialysis
- Absence of normal fistula vibration or “thrill”
Treatment
- Clot-dissolving medications such as urokinase or tissue plasminogen activator (TPA)
- Placement of a stent or filter when medically necessary to help maintain blood flow and reduce future clot formation
Keeping Your Fistula Functioning Properly
If your fistula is functioning normally, continue following your prescribed dialysis treatment plan.
Contact Your Healthcare Provider Immediately If You Notice:
- Blood or clots in the needleless connector or access site
- Significant reduction in blood flow
- Pain during dialysis treatments
- Swelling around the fistula
- Signs of infection
- Loss of normal blood flow signals
Weekly Self-Monitoring Checklist
Inspect your fistula at least once each week for:
- Signs of clotting
- Narrowing or swelling
- Changes in blood flow
- Loss of color-flow Doppler signals
- Redness or signs of infection
Regular monitoring and prompt treatment of any abnormalities can help preserve fistula function and ensure successful hemodialysis treatments.
