01
AV Fistula Creation
A suitable superficial vein is connected to a nearby artery to create an access with higher blood flow for dialysis needle access.

AV Fistula Treatment in Hyderabad
AV fistula creation, salvage surgery, fistula angioplasty and central vein angioplasty for dialysis vascular access, with individualized assessment by a vascular specialist.
Understanding dialysis access
What Is an AV Fistula?
An arteriovenous (AV) fistula is a surgically created connection between an artery and a vein, usually in the arm. This increases blood flow through the vein so it can develop into a usable access for haemodialysis.
02
AV Graft
If suitable veins are not available, a synthetic graft may be placed between an artery and vein to provide an alternative dialysis access.
03
Access Salvage & Angioplasty
Narrowing or blockage can affect dialysis access. Selected patients may require fistula salvage, thrombosis treatment or angioplasty.
When AV fistula treatment is needed
Why Is Vascular Access Important for Dialysis?
The source page explains that dialysis requires dependable access to the bloodstream. Vascular access procedures are designed to provide a vein that can be punctured repeatedly and maintain adequate blood flow.
For Haemodialysis
Dialysis access allows blood to travel to the dialysis machine for filtration and then return to the circulation.
When Veins Need an Alternative
If the available veins are thin, scarred or unsuitable, a graft may be considered instead of a native fistula.
When Access Stops Working Well
Stenosis, thrombosis, swelling or other access problems may require timely vascular assessment and treatment.
Seek prompt medical advice for access problemsIf the access has increasing swelling, redness, bleeding, worsening pain, fever, reduced thrill, severe hand coolness or numbness, contact the treating dialysis/vascular team promptly.
Treatment options
AV Fistula Creation, Salvage & Angioplasty
The treatment depends on whether the patient needs a new access or an existing fistula/graft needs to be preserved or restored.
AV Fistula Creation
The surgeon identifies a suitable artery and superficial vein, usually in the upper limb, and creates a direct arterio-venous connection. The fistula then needs time to mature before routine dialysis needle use.
- Vein and artery suitability are assessed first.
- The non-dominant arm may be selected when appropriate.
- Fistula maturation takes time and varies between patients.
- Follow-up helps assess whether the access is developing adequately.
Salvage & Angioplasty
When an established fistula or graft develops narrowing or blockage, selected patients may undergo procedures intended to restore access flow and preserve the dialysis access.
- Fistula angioplasty may be used for suitable narrowing.
- Thrombosed access may require clot-directed or surgical treatment.
- Central venous narrowing may require central vein intervention.
- The exact approach depends on imaging and access anatomy.
Before the procedure
How AV Fistula Treatment Is Planned
The original HVC page describes examination and vascular imaging before selecting the access site or treatment approach.
Clinical Assessment
The arms and circulation are examined and the patient's dialysis and medical history is reviewed.
Vein Mapping
A duplex scan may be arranged to map suitable arm veins and assess the vascular anatomy.
Access Planning
The vascular surgeon selects the appropriate fistula, graft or access intervention based on findings.
Follow-Up
After treatment, the access is monitored for maturation, function and possible complications.
Fistula maturation
What Happens After AV Fistula Creation?
The source page notes that the fistula gradually dilates and its wall becomes stronger as it matures, making it suitable for dialysis access.
Allow Time to Mature
A newly created fistula is not necessarily ready for immediate dialysis needle use. The maturation period varies and should be assessed by the clinical team.
Check the Thrill
Patients are taught to feel for a vibration or “thrill” over the access. A change or absence of the thrill should be reported promptly.
Protect the Access Arm
Avoid unnecessary pressure or trauma to the access and follow the dialysis team's instructions for access care.
Access care
How to Protect Your AV Fistula or Graft
Protecting dialysis access is an important part of long-term vascular access care.
Monitor Daily
- Check for the normal thrill as instructed.
- Watch for swelling, redness or bleeding.
- Report significant changes promptly.
Avoid Pressure
- Do not carry heavy loads with the access arm.
- Avoid sleeping on the access arm.
- Avoid tight clothing or jewellery around the access.
Protect the Vein
- Do not use the access arm for routine blood pressure measurements when advised otherwise by your care team.
- Avoid unnecessary blood draws or injections through the access.
- Keep the access area clean and follow dialysis-unit instructions.
Possible complications
AV Fistula & Dialysis Access Problems
Like other vascular procedures, dialysis access creation and maintenance can have complications. Early assessment can be important when access function changes.
Bleeding & Infection
Bleeding or infection can occur around a fistula or graft and should be assessed promptly if symptoms develop.
Stenosis & Thrombosis
Narrowing or clotting can reduce access flow and may interfere with effective dialysis.
Hand Ischaemia
Some patients can develop reduced blood flow to the hand, sometimes called steal syndrome. Significant coolness, numbness or pain needs medical assessment.

Frequently asked questions
AV Fistula Treatment FAQs
What is an AV fistula?
An AV fistula is a surgically created connection between an artery and vein, usually in the arm, to provide vascular access for haemodialysis.
Why is an AV fistula used for dialysis?
It provides a high-flow vascular access that can be repeatedly punctured for haemodialysis.
What if my veins are too small or damaged?
If suitable veins are not available, a synthetic graft may be considered as an alternative dialysis access.
How is an AV fistula evaluated before surgery?
The vascular surgeon examines the limb and may use duplex ultrasound to map veins and assess the arteries. Additional imaging may be used in selected cases.
How long does an AV fistula take to mature?
Maturation varies. The source page notes that a fistula may become suitable for larger dialysis needles after several weeks, but the exact timing depends on individual development and clinical assessment.
What is fistula angioplasty?
Fistula angioplasty is an endovascular procedure used in selected patients to treat narrowing in a dialysis fistula and improve access flow.
What is AV fistula salvage surgery?
Salvage treatment aims to preserve or restore a dysfunctional dialysis access when problems such as narrowing or thrombosis occur.
Can a fistula develop complications?
Potential complications include bleeding, infection, stenosis, thrombosis, swelling, neuropathy, hand ischaemia and aneurysm formation.
Can blood pressure be checked on the fistula arm?
Patients should follow their dialysis and vascular team's instructions. The original HVC page advises avoiding blood pressure measurements, blood draws and injections in the fistula or graft arm.
How can I book an AV fistula consultation in Hyderabad?
Contact Hyderabad Vascular Center to arrange a vascular evaluation for AV fistula creation, salvage or other dialysis access treatment.

Medical disclaimer: This page is for general educational information and does not replace an individual medical consultation. AV fistula and dialysis access decisions should be made after assessment by the treating nephrology and vascular teams. If there is severe bleeding, sudden loss of access thrill, severe hand pain/coolness, fever or another urgent concern, seek prompt medical care.
