An AV fistula is a connection that’s made between an artery and a vein for dialysis access. A surgical procedure, done in the operating room, is required to stitch together two vessels to create an AV fistula.

Why is AV fistula created for hemodialysis?

An AV fistula causes extra pressure and extra blood to flow into the vein, making it grow large and strong. The larger vein provides easy, reliable access to blood vessels. Without this kind of access, regular hemodialysis sessions would not be possible.

What is the procedure for a fistula?

Fistulotomy. The surgeon cuts the fistula’s internal opening, scrapes and flushes out the infected tissue, and then flattens the channel and stitches it in place. To treat a more complicated fistula, the surgeon may need to remove some of the channel.

Why is arteriovenous fistula preferred?

They carry a relatively high risk of infection and clotting. Arteriovenous fistula – considered the gold standard for vascular access in hemodialysis patients and the first choice whenever possible. AV fistulas are associated with decreased mortality and morbidity among hemodialysis patients.

What are advantages of an arteriovenous graft over a fistula?

They’re also less prone to infection or other expensive complications. Fistulas Last Longer. If a graft is well cared for, it may last for several years, but a healthy AV fistula is still more durable. (ii) Because it requires less maintenance, fistulas usually present a better long-term option.

What are the advantages of an arteriovenous fistula?

Once the fistula has matured, it can provide good blood flow for many years of hemodialysis. The benefits of a fistula compared to other access types include: lower risk of infections. lower risk of forming clots. performs better. allows for greater blood flow. lasts longer , sometimes even for decades if well-cared for.

What are the complications of fistula surgery?

Losing bowel control. This means you can’t control when you poo or sometimes just when you pass wind.

  • Your wound takes longer than usual to heal.
  • The fistula may come back. The chance of this happening varies between different procedures.
  • Narrowing (stenosis) of your anal canal – the end of your back passage.
  • What is the difference shunt vs fistula?

    How long is fistula surgery for dialysis?

    After surgery, it takes at least 1 month, although it often takes 3 to 4 months or more for a fistula to mature enough for dialysis.
