Vascular Access for Dialysis

Vascular access for dialysis in Bengaluru is an important part of haemodialysis care for people with advanced kidney disease. It provides a reliable route for blood to leave the body, pass through the dialysis machine for filtration, and return safely. The type of vascular access recommended depends on kidney function, dialysis plans, blood vessel condition, overall health, and how urgently dialysis is needed.

For patients who require long-term haemodialysis, planning vascular access early can help reduce complications and avoid emergency dialysis through a temporary catheter. A specialist can assess the blood vessels and recommend the most suitable option based on the patient's individual needs.

What Is Vascular Access for Dialysis?

Vascular access is a specially created or placed pathway that allows healthcare professionals to access the bloodstream during haemodialysis. Since dialysis usually requires repeated access to the blood vessels, the access needs to provide adequate blood flow while also remaining functional and safe over time.

The main types of haemodialysis vascular access are:

• Arteriovenous (AV) fistula
• Arteriovenous (AV) graft
• Central venous catheter

Current vascular access guidance generally favours an AV fistula or graft over a central venous catheter for many patients who need ongoing haemodialysis because AV access is associated with a lower infection risk. However, the appropriate choice should be individualised according to the patient's clinical circumstances and treatment goals.

Types of Vascular Access for Dialysis

1. Arteriovenous Fistula

An AV fistula is created by surgically connecting an artery to a nearby vein, usually in the arm. The increased blood flow through the vein gradually makes it stronger and larger, allowing it to be repeatedly accessed for dialysis.

An AV fistula is often preferred for suitable patients who need long-term haemodialysis because it can provide durable access and generally has fewer infection-related complications than a catheter.

Depending on the patient's blood vessels, a fistula may be created at the wrist or upper arm. The choice of location depends on factors such as vessel size, previous procedures, and the patient's vascular anatomy.
