Introduction

For patients with kidney failure who depend on haemodialysis, creating a safe and long-lasting vascular access is critical. Among all access options, the AV fistula (arteriovenous fistula) is considered the gold standard. At Iswarya Hospital, OMR, Chennai, we provide advanced brachio AV fistula surgery at the elbow, performed by skilled surgeons in modern operation theatres to ensure reliable dialysis access and better patient outcomes.

What Is a Brachio AV Fistula at the Elbow?

A brachial AV fistula involves directly connecting the brachial artery (in the upper arm near the elbow) to a nearby vein. This connection creates a high-flow vessel suitable for repeated needle insertions during dialysis. Over time, the vein becomes thicker and stronger, making it ideal for long-term haemodialysis.

Why Is It Needed?

1. Forearm veins are too small or unsuitable for a fistula
2. Long-term dialysis access is required
3. Other access sites have failed or are exhausted
4. Patients need a durable and natural access that lasts longer than synthetic grafts

How Is It Done at Iswarya Hospital?

At Iswarya Hospital, the procedure is done in our advanced sterile OTs:

1. The vascular surgeon identifies the brachial artery and a suitable vein near the elbow.
2. A surgical connection (anastomosis) is created between the artery and vein.
3. Blood flow increases, gradually strengthening the vein for dialysis use.
4. Patients are given guidance on arm care and follow-ups to monitor maturation.

Our team of vascular surgeons, nephrologists, and anaesthesiologists ensures safe, precise, and patient-friendly care.

Benefits of a Brachio AV Fistula

1. Gold standard for haemodialysis access
2. Lasts longer than grafts or catheters
3. Lower risk of infection and clotting
4. Provides high blood flow for efficient dialysis
5. No need for synthetic material – uses your own vessels

Recovery and Aftercare

1. The fistula takes 6–8 weeks to mature before it can be used.
2. Patients receive instructions on arm exercises to help vein enlargement.
3. Regular check-ups are scheduled at Iswarya Hospital to monitor fistula function.
4. 24/7 dialysis and emergency care support are available if complications arise.

FAQs

1. How long does a brachial AV fistula take to mature?

Usually 6–8 weeks, but sometimes up to 3 months before it’s ready for dialysis use.

2. Is an AV fistula better than an AV graft?

Yes. Fistulas generally last longer, have fewer complications, and are considered the best access for dialysis.

3. Will the fistula be visible on my arm?

Yes, you may notice a slight bulge or vibration (thrill) where the vein enlarges.

4. What are possible risks?

Risks include delayed maturation, narrowing, or clotting but with proper monitoring at Iswarya Hospital, most issues are preventable.

5. Can both arms be used for fistula creation?

Yes, depending on your vein condition. Doctors at Iswarya Hospital will evaluate and suggest the best site.
