AV Fistula for Dialysis

About AV Fistula for Dialysis

An arteriovenous fistula joins an artery and a vein to create a high-flow vessel suitable for repeated cannulation by a dialysis machine. Dialysis is necessary in chronic, end-stage kidney disease, where the kidneys can no longer filter blood effectively or maintain normal urine output. The dialysis machine performs this filtration externally, and reliable, repeatable access through dialysis fistula creation surgery is fundamental to its safe operation.

AV fistulas are most commonly formed at the left wrist, since this preserves the dominant arm and matches everyday haemodialysis fistula treatment practice. Where forearm vessels are unsuitable, alternatives include the right wrist, the elbow, and the upper arm. As an experienced av fistula surgeon team in Lucknow, we map the arteries and veins clinically, and use ultrasound when needed, to choose the site most likely to yield a successful long-term access.

The procedure at Kayakriti is typically performed under local or regional anaesthesia, often as a day-case or short-stay admission. We use microvascular techniques to suture the artery and vein under magnification, an approach that supports accuracy and longevity. Vascular access surgery in Lucknow performed in this way offers patients an option that is generally well tolerated even when they have multiple comorbidities common in end-stage kidney disease.

Once formed, the fistula matures over several weeks. Pre-operative arterial flow of around 85-110 mL/min increases immediately to 400-500 mL/min and may reach 700-1,000 mL/min within a month. Elbow fistulas usually carry larger volumes than wrist fistulas. Maturation takes around six weeks before kidney dialysis access surgery is considered ready for routine cannulation. Pseudoaneurysms and other complications can occur and are managed promptly when they arise.

What to expect

• Initial consultation with vessel mapping, comorbidity review, and discussion of access options.
• Surgery is performed under local or regional anaesthesia using microvascular technique.
• Most patients are discharged the same day or after a short observation stay.
• Patients learn to feel for the thrill, protect the arm, and recognise early warning signs.
• Maturation review around six weeks confirms readiness for routine dialysis cannulation.

Recovery

• Avoid heavy lifting, tight sleeves, or blood pressure cuffs on the access arm.
• Keep the wound clean and dry, following the dressing schedule provided.
• Maturation typically takes about six weeks before first dialysis use.
• Report sudden swelling, pain, loss of thrill, or fever to the team without delay.
