AV fistula creation and repair
Arteriovenous fistula
Creating the fistula in the arm for dialysis, and repairing one that has stopped working.
What is happening inside your body
When the kidneys fail, dialysis does their job of cleaning the blood. For this, the machine needs a strong connection to your blood flow. A small operation joins an artery to a vein in your arm, usually at the wrist or elbow. Over some weeks this vein grows stronger and larger, giving a reliable point for the dialysis needles. This join is called a fistula.
A well-made dialysis access makes every dialysis session easier and safer. Dr. Sajjad creates new fistulas and repairs failing ones so your treatment is not held up.
Signs to look out for
- You have been told your kidneys are failing and you will need dialysis
- You are on dialysis through a temporary line and need a lasting access
- An existing fistula has stopped working, become blocked, or is not developing
- Swelling or problems around an old access site
How it is treated
Dr. Sajjad creates the fistula in a small operation, usually with the arm numbed, and you go home the same day. It then takes several weeks to mature (grow strong enough to use). If a fistula stops working, he can often repair it or create a new one, so your dialysis is not interrupted for long.
What recovery looks like
-
Day of surgery: a small cut on the arm, mild soreness, home the same day.
-
First weeks: simple arm exercises as advised help the fistula grow strong.
-
Six to eight weeks: the fistula usually becomes ready for dialysis needles.
-
Regular checks make sure it stays healthy and working well.
Common questions
How long before my fistula can be used for dialysis?
Most fistulas need about six to eight weeks to mature before they are strong enough to use. This is why it is best to have it made in good time, before you urgently need dialysis.
Is creating a fistula a major operation?
No. It is a small operation, usually done with the arm numbed, and you go home the same day.
My old fistula has stopped working. Can it be fixed?
Often yes. Many blocked or failing fistulas can be repaired, or a new access can be created, so your dialysis continues with as little interruption as possible.
