There are two types of permanent vascular access for dialysis: arteriovenous (AV) fistula and arteriovenous (AV) graft. A surgeon creates an AV fistula by connecting an artery directly to a vein, most commonly in the forearm. Alternatively, a surgeon creates an AV graft by connecting an artery to a vein using a synthetic tube or graft.
Sometimes the blood flow from an AV fistula or AV graft becomes too low due to a narrowing, a blood clot or because a collateral, or accessory, blood vessel forms and is diverting blood flow.
An interventional radiologist can correct these problems with fistula intervention or graft intervention.
Using live X-ray (fluoroscopy) for guidance, the doctor will insert a tiny tube, called a catheter into a vein or artery, usually in your child’s arm or leg, and guide it to the fistula or graft.
Then one of three things will happen:
The procedure is considered low risk. However, potential complications include:
No. Depending on your child’s medical history, we will give either intravenous sedation or general anesthesia.
Your child will be taken to a recovery room and in some cases may be admitted to the hospital for observation. Your child might have some mild discomfort. Check with your primary care physician whether you may give your child over-the-counter pain medication.
The bandage must stay dry and in place for 48 hours. You may sponge bathe your child during this time, as long as the bandage stays dry. After 48 hours you may remove the clear bandage and gauze and your child can take a shower or take a bath, as long as the site isn’t immersed in water. Leave the Steri-Strips® (white strips) in place. Do not immerse the site in water until the Steri-Strips fall off. If they haven’t fallen off after seven days, you may remove them at that time.
Your child may return to normal activity as tolerated.
