Vascular Access Treatment in Hyderabad
Specialist evaluation and treatment of vascular access for patients receiving haemodialysis, including AV fistula planning, access salvage, fistula-related interventions and selected central venous procedures.
What Is Vascular Access?
Vascular access provides a dependable route for blood to leave the body and return during haemodialysis. Common access options include an arteriovenous fistula, arteriovenous graft and dialysis catheter.
AV Fistula
An arteriovenous fistula connects an artery to a vein to create durable access for haemodialysis when appropriate.
AV Graft
An arteriovenous graft uses a conduit to connect an artery and vein when a native fistula is not suitable.
Dialysis Catheter
Temporary or longer-term catheter access may be used when immediate or alternative dialysis access is required.
Signs That Your Dialysis Access Needs Assessment
Dialysis patients should report changes in their access to their dialysis and vascular teams promptly.
Reduced or Absent Thrill
A change in the usual vibration or “thrill” over an AV fistula can indicate reduced blood flow or thrombosis.
Difficulty During Dialysis
Repeated difficulty with needle placement, poor blood-flow rates or increased venous pressures may require access evaluation.
Swelling of the Arm
New or increasing arm swelling can be associated with venous outflow problems and should be assessed.
Bleeding
Persistent or unusually heavy bleeding from the access site requires prompt medical attention.
Redness or Discharge
Redness, warmth, tenderness or discharge around an access site may indicate infection.
Hand Coldness or Pain
New hand pain, numbness, weakness or coldness may require assessment of circulation.
Vascular Access Procedures
The HVC vascular access service includes surgical creation and selected procedures used to maintain, restore or revise dialysis access.
AV Fistula Creation
Creation of a native arteriovenous fistula after assessment of the available arteries and veins.
Fistula Salvage & Revision
Evaluation and selected surgical procedures to preserve or revise a functioning but compromised access.
Fistuloplasty
Balloon angioplasty may be used to treat a narrowing that limits blood flow through a dialysis fistula.
Fistulogram
Contrast imaging can help identify stenosis, obstruction or other access-flow abnormalities before or during intervention.
Thrombectomy
Selected thrombosed fistulas may require clot removal combined with treatment of the underlying narrowing.
Central Vein Angioplasty
Selected patients with central venous narrowing may require endovascular treatment to improve venous outflow.
How Vascular Access Treatment Is Planned
Access treatment is individualized according to the patient's dialysis history, vascular anatomy, access function and the nature of the problem.
Clinical assessment
The vascular team reviews the dialysis access, symptoms, previous procedures and dialysis-related concerns.
Vascular mapping or imaging
Ultrasound mapping or other vascular imaging may be used to assess arteries, veins and the existing access.
Identify the access problem
The team determines whether the issue is stenosis, thrombosis, poor maturation, venous outflow obstruction, infection or another access complication.
Select the appropriate intervention
Treatment may involve observation, angioplasty, thrombectomy, revision, creation of new access or another procedure depending on the findings.
Access surveillance
Continued observation and communication with the dialysis team can help identify recurrent problems early.
Why Fistula Preservation Matters
For patients who depend on haemodialysis, preserving a functioning access can be an important part of ongoing kidney-care treatment.
Protect the Access
- Follow the dialysis team's instructions for access care.
- Check the usual thrill as instructed by your clinical team.
- Report changes in flow, swelling, pain or bleeding.
- Avoid unnecessary trauma to the access arm.
Act Early When Problems Appear
Access dysfunction can worsen if an underlying narrowing or thrombosis is not assessed. Early communication with the dialysis team allows appropriate investigation and referral when needed.

Vascular Access Treatment in Hyderabad – FAQs
What is vascular access for dialysis?
Vascular access is the route used to access the bloodstream during haemodialysis. Common types include AV fistulas, AV grafts and dialysis catheters.
What is an AV fistula?
An AV fistula is a surgically created connection between an artery and a vein, allowing the vein to become suitable for repeated haemodialysis access when appropriate.
What is fistuloplasty?
Fistuloplasty is balloon angioplasty used to widen a narrowed segment of a dialysis fistula or its outflow when clinically appropriate.
What is a fistulogram?
A fistulogram is an imaging study that uses contrast to evaluate the blood vessels and identify narrowing or other abnormalities affecting dialysis access.
What happens if an AV fistula becomes blocked?
A blocked or thrombosed fistula needs prompt assessment. Selected patients may require thrombectomy and treatment of an underlying narrowing, while others may require revision or another access strategy.
What are signs of an AV fistula problem?
Changes in the normal thrill, poor dialysis blood-flow rates, repeated cannulation problems, swelling, bleeding, infection or new hand pain/coldness should be reported to the dialysis or vascular team.
Can an AV fistula be saved after it stops working?
Some thrombosed or narrowed fistulas can be salvaged with endovascular or surgical treatment. Suitability depends on the access anatomy and clinical findings.
What is central vein angioplasty?
Central vein angioplasty is an endovascular procedure that can be used in selected patients with significant narrowing of a central vein affecting dialysis access outflow.
When should a dialysis patient seek urgent help for access problems?
Seek urgent medical attention for uncontrolled bleeding, severe swelling or pain, signs of serious infection, sudden loss of the usual fistula thrill or other rapidly worsening access problems.
Having Problems With Your AV Fistula or Dialysis Access?
Prompt vascular assessment can help determine whether the access requires imaging, angioplasty, thrombectomy, revision or another treatment.
