Av fistula and dialysis access salvage best surgeon in Kolkata

 An AV fistula is an artificial surgical connection between an artery and a vein. It makes a vein fat, thick and strong to sustain dialysis needle..



  1. Surgical Creation: A vascular surgeon performs the procedure to create the AV fistula. During the surgery, an artery and a nearby vein are surgically connected, usually in the forearm or upper arm. This connection allows arterial blood, which carries oxygen and vital nutrients, to flow directly into the vein.

  2. Vein Maturation: Following the surgery, the vein gradually enlarges and becomes thicker due to the increased blood flow from the artery. This process, known as vein maturation, typically takes several weeks to months.

  3. Preparation for Dialysis: Once the AV fistula has matured sufficiently, it becomes suitable for use in hemodialysis. Dialysis needles are inserted into the enlarged vein to access the bloodstream for dialysis treatments.

  4. Benefits of AV Fistula: AV fistulas are considered the preferred type of vascular access for hemodialysis because they have fewer complications and a longer lifespan compared to other access methods like arteriovenous grafts or central venous catheters. Additionally, they provide better blood flow rates, which is crucial for effective dialysis.

  5. Care and Maintenance: Proper care and maintenance of the AV fistula are essential to ensure its long-term function. Patients are advised to protect the fistula from injury, avoid constrictive clothing or accessories that could impede blood flow, and regularly monitor for signs of infection or complications.
