Dialysis Access Treatment in Singapore
Minimally Invasive Vascular Treatments for Dialysis Access
Dialysis depends on reliable access to the bloodstream. For patients undergoing or preparing for haemodialysis, this access may be provided through an arteriovenous fistula, arteriovenous graft or dialysis catheter.
Over time, dialysis access can develop problems such as narrowing, reduced blood flow or clot formation. These issues may affect the ability to receive effective dialysis and may require vascular assessment and treatment.
At the Supreme Vascular and Interventional Clinic, minimally invasive, image-guided procedures can be used to assess and treat selected problems affecting dialysis access.
Care is led by Dr. Manish Taneja, providing specialist vascular and interventional expertise with a continuum of care under one roof.

What Is Dialysis Access Treatment?
Dialysis access treatment refers to minimally invasive vascular procedures used to maintain, restore or establish access to the bloodstream for patients requiring haemodialysis.
A functioning vascular access is essential because haemodialysis requires blood to flow from the body to the dialysis machine and back again.
Different types of access may be used, including:
- Arteriovenous (AV) fistulas
- AV grafts
- Dialysis catheters
When these access routes develop problems, image-guided vascular procedures may help address selected complications.
How Does Dialysis Access Treatment Work?
Dialysis access treatment uses minimally invasive, image-guided techniques to assess and address problems affecting an arteriovenous (AV) fistula, AV graft or dialysis catheter. Depending on the underlying issue, a small catheter or other specialised device may be used to examine blood flow, widen a narrowed area, treat a blood clot or establish suitable vascular access for haemodialysis. Imaging guidance helps the specialist accurately identify and target the area requiring treatment.
The exact procedure depends on the type of dialysis access and the problem being treated. After the treatment, blood flow may be assessed to determine the treatment result, with follow-up and further care planned according to the patient's individual dialysis needs.
Types of Dialysis Access Treatments
Different Procedures for Different Access Needs
The most appropriate treatment depends on the type of dialysis access and the underlying problem.
Dialysis Access Angioplasty
Dialysis access angioplasty is a minimally invasive procedure used to widen selected narrowed areas within an AV fistula, AV graft or other dialysis access.
A small balloon is positioned at the area of narrowing and carefully inflated to improve the opening of the affected vessel or access segment.
Dialysis Catheter Insertion
A dialysis catheter provides direct access to the bloodstream when temporary or other suitable vascular access is required for haemodialysis.
The catheter is inserted into a suitable central vein using image guidance.
Fistuloplasty
Fistuloplasty is a minimally invasive procedure that uses balloon angioplasty to treat selected narrowing affecting an AV fistula.
What Problems Can Affect Dialysis Access?
Dialysis access can develop problems that affect blood flow or the ability to carry out haemodialysis effectively.
These may include:
Narrowing or Stenosis
A section of the AV fistula, graft or associated blood vessel may become narrowed, reducing blood flow.
Blood Clot Formation
A clot may partially or completely block the dialysis access.
Reduced Access Flow
Changes in blood flow may affect the performance of the vascular access.
Access Dysfunction
Problems affecting the fistula, graft or catheter may interfere with dialysis treatment.
Catheter-Related Issues
Dialysis catheters can develop flow or positioning problems and may require assessment or intervention.
The appropriate treatment depends on the underlying cause of the access problem.
When Might Dialysis Access Treatment Be Considered?
Vascular assessment may be recommended when there are signs that dialysis access is not functioning as expected.
Depending on the type of access, possible signs may include:
- Difficulty achieving adequate blood flow during dialysis
- Changes in the appearance of the access
- Swelling around the access
- Prolonged bleeding after dialysis needle removal
- Changes in the usual sensation or vibration over an AV fistula
- Repeated dialysis access problems
- Difficulty using the access for dialysis
These symptoms can have different causes, and a proper assessment is important.
Potential Benefits of Dialysis Access Treatment
A Targeted Minimally Invasive Approach
For appropriately selected patients, dialysis access treatment may offer several potential benefits.
Minimally Invasive
Many dialysis access procedures can be performed using catheter-based techniques rather than conventional open surgery.
Helps Address Access Problems
Treatment can target selected narrowing, clot formation or other problems affecting dialysis access.
Image-Guided Assessment
Imaging can help identify the location and nature of the access problem and guide treatment.
May Help Restore Blood Flow
Procedures such as angioplasty or thrombolysis may help improve blood flow through selected dialysis access.
Supports Ongoing Haemodialysis
Maintaining a functioning vascular access can help support continued haemodialysis treatment.
Different Treatment Options
The treatment approach can be tailored according to whether the patient has an AV fistula, AV graft or dialysis catheter.
What Are the Potential Risks and Considerations?
Understanding What to Expect
Dialysis access procedures are minimally invasive, but all medical procedures involve potential risks and considerations.
These may include:
- Bruising or discomfort around the access site
- Minor bleeding
- Temporary swelling
- Recurrence or persistence of narrowing
- Recurrent clot formation
- Reaction to contrast material
- The possibility of requiring further treatment
Your individual risks and the specific considerations depend on the type of dialysis access and procedure being performed.
Your specialist will explain the potential benefits, risks and alternatives before treatment.
Recovery After Dialysis Access Treatment
What Can You Expect After Treatment?
Recovery depends on the type of procedure performed and the condition of the dialysis access. Most patients go home the same day and can resume light daily activities and work within 1 to 3 days.
After treatment, you may be advised to:
- Monitor the access site
- Follow instructions regarding activity
- Attend dialysis or follow-up appointments as advised
- Watch for changes in swelling, bleeding or blood flow
- Follow specific care instructions for a dialysis catheter where applicable
Your aftercare plan will depend on the procedure and your individual circumstances.
