Fistuloplasty in Singapore
Minimally Invasive Treatment for Narrowed Dialysis Fistulas
Fistuloplasty is a minimally invasive, image-guided procedure used to treat narrowing within an arteriovenous (AV) fistula used for haemodialysis.
Over time, areas of narrowing, also known as stenosis, can develop within a dialysis fistula. This may reduce blood flow and affect how well the fistula functions during haemodialysis.
During fistuloplasty, a small balloon is positioned at the narrowed area and carefully inflated to widen the affected section and improve blood flow through the fistula.
At the Supreme Vascular and Interventional Clinic, Dr. Manish Taneja provides specialist assessment and minimally invasive treatment for selected dialysis access problems, with a continuum of care under one roof.

What Is Fistuloplasty?
An arteriovenous fistula is created by connecting an artery and a vein to provide reliable vascular access for haemodialysis.
Over time, part of the fistula may become narrowed. This narrowing can reduce blood flow and may interfere with the ability to use the fistula effectively for dialysis.
Fistuloplasty is a catheter-based procedure used to widen selected narrowed sections of the AV fistula. It is also commonly referred to as AV fistula angioplasty.
The procedure aims to improve blood flow through the fistula and help maintain its function for haemodialysis.
How Does Fistuloplasty Work?
Fistuloplasty is performed using minimally invasive, image-guided techniques. A small catheter is introduced into the dialysis fistula and imaging is used to identify the narrowed area. A specialised balloon is then positioned across the narrowing and carefully inflated to widen the affected section. Once the balloon is removed, further imaging may be used to assess blood flow through the fistula and determine the result of the treatment.
The exact approach depends on the location and characteristics of the narrowing, as well as the overall condition of the dialysis access.
When Might Fistuloplasty Be Needed?
Fistuloplasty may be considered when an AV fistula develops narrowing that affects blood flow or its ability to support haemodialysis.
Possible signs of fistula dysfunction may include:
Reduced Blood Flow During Dialysis
A narrowed section may affect the amount of blood that can flow through the fistula during treatment.
Difficulty Using the Fistula
Repeated difficulty inserting dialysis needles or using the fistula may indicate an underlying access problem.
Changes in the Fistula
Changes in the appearance, feel or usual vibration of the fistula may require further assessment.
Prolonged Bleeding
Bleeding that takes longer than usual to stop after dialysis needle removal can sometimes be associated with access narrowing.
Swelling
Narrowing may affect blood drainage and contribute to swelling around the access or nearby limb.
Abnormal Dialysis Access Findings
Monitoring during dialysis may identify changes that suggest the fistula requires further assessment.
These signs can have different causes, and appropriate vascular assessment is important.
What Happens During Fistuloplasty?
A Targeted, Image-Guided Procedure
Fistuloplasty is performed through a minimally invasive approach.
Access to the Fistula
A small access point is created to allow a catheter to enter the dialysis fistula.
Imaging Assessment
Contrast imaging is used to visualise the fistula and identify the location and extent of narrowing.
Balloon Angioplasty
A specialised balloon is guided to the narrowed area and inflated to widen the affected section.
Assessment of Blood Flow
Further imaging may be performed to assess the improvement in blood flow following treatment.
Completion and Recovery
The catheter is removed and the access site is monitored after the procedure.
Potential Benefits of Fistuloplasty
A Targeted Minimally Invasive Approach
For appropriately selected patients, fistuloplasty may offer several potential benefits.
Minimally Invasive
Treatment is performed through a small vascular access point rather than conventional open surgery.
Targets Narrowed Areas
Balloon angioplasty is used to directly widen selected areas of narrowing within the dialysis fistula.
Image-Guided Treatment
Imaging helps identify the location of the narrowing and guide the treatment.
May Improve Blood Flow
Widening the narrowed section may help improve blood flow through the fistula.
Supports Ongoing Haemodialysis
Maintaining a functioning AV fistula can help support reliable vascular access for haemodialysis.
Can Be Repeated When Appropriate
Some patients may develop recurrent narrowing over time, and further intervention may be considered when clinically appropriate.
Individualised Treatment
The treatment approach can be tailored according to the location, severity and characteristics of the narrowing and the individual dialysis access.
What Are the Potential Risks and Considerations?
Understanding What to Expect
Fistuloplasty is a minimally invasive procedure, but like all vascular interventions, it involves potential risks and considerations.
These may include:
- Temporary discomfort or bruising around the access site
- Minor bleeding
- Temporary swelling
- Recurrent narrowing over time
- Reaction to contrast material
- The possibility of requiring additional treatment
The specific considerations depend on the location and characteristics of the narrowing and the condition of the dialysis fistula.
A detailed assessment is performed before treatment to determine whether the potential benefits outweigh the risks.
Recovery After Fistuloplasty
What Can You Expect After Treatment?
Recovery after fistuloplasty is generally relatively short with same day discharge, although this depends on the individual procedure and condition of the dialysis access. The procedure typically takes 30-60 minutes. If it includes a more complex procedure across single or multiple narrow areas, it may take longer.
After treatment, you may be advised to:
- Monitor the fistula and access site
- Follow instructions regarding activity
- Watch for unusual swelling or bleeding
- Attend dialysis as advised by your treating team
- Follow any specific instructions regarding use of the fistula
Your specialist will provide personalised follow-up instructions based on your condition.

Frequently Asked Questions About Fistuloplasty
What is fistuloplasty?
Fistuloplasty is a minimally invasive procedure that uses balloon angioplasty to treat selected narrowing within an AV fistula used for haemodialysis.
Is fistuloplasty the same as angioplasty?
Fistuloplasty is a type of angioplasty specifically performed on an arteriovenous fistula.
Why does an AV fistula become narrowed?
Narrowing can develop over time due to changes within the blood vessel or fistula. The exact cause and location can vary between patients.
How does fistuloplasty improve blood flow?
A small balloon is inflated within the narrowed area to widen the affected section, which may improve blood flow through the fistula.
Is fistuloplasty a surgical procedure?
It is a minimally invasive, catheter-based vascular procedure rather than conventional open surgery.
How long does fistuloplasty take?
The duration depends on the location and complexity of the narrowing and whether additional treatment is required. The procedure typically takes 30-60 minutes. If it includes a more complex procedure across single or multiple narrow areas, it may take longer.
Can the fistula become narrowed again?
Some patients may develop recurrent narrowing and may require further monitoring or treatment.
Can I use my fistula for dialysis after fistuloplasty?
This depends on the individual treatment and condition of the fistula. Your specialist will advise when and how the fistula can next be used.
What is the difference between fistuloplasty and dialysis access angioplasty?
Fistuloplasty specifically refers to angioplasty performed on an AV fistula. Dialysis access angioplasty is a broader term that may also include treatment of other types of dialysis access.
