An AV Fistula (Arteriovenous Fistula) is a surgical procedure used to create a direct connection between an artery and vein in the arm to be used as long-term access for hemodialysis in patients with chronic kidney disease.
Procedure Type
Surgical, Minimally invasive
Why Is an Av Fistula Performed?
- An AV (arteriovenous) fistula surgery may be needed in certain medical conditions where there is a need for long-term hemodialysis treatment for end-stage kidney disease.
- An AV fistula surgery is necessary because it provides a reliable and long-lasting access point for the hemodialysis machine. This is important because hemodialysis is required on a regular basis, and the access point must be durable enough to withstand frequent needle punctures and high blood flow rates.
Who Is a Candidate for an Av Fistula Surgery?
Candidates for AV fistula surgery typically include patients with:
- End-stage renal disease requiring hemodialysis.
- Sufficient blood flow in the artery and vein to create the fistula.
- Good overall health and a stable medical condition.
- Adequate arm function and strength to tolerate the procedure.
- A willingness to commit to ongoing dialysis treatment.
- No evidence of active infection or clotting disorders that would interfere with the surgery.
- Absence of severe peripheral vascular disease or previous vascular access surgery in the same arm.
Preparation of AV Fistula Surgery
- Patients will be asked about their personal and family history, medications, allergies and other chronic conditions.
- A physical exam may be conducted, and the doctor may ask to perform lab, imaging and diagnostic tests to ensure the patient is fit for the procedure.
- The doctor may start or stop certain medications.
- Patients will not be permitted to eat a few hours before the procedure.
How Is the Procedure Performed?
- The surgeon makes an incision in the arm and creates a connection between an artery and vein, usually in the forearm.
- The connection is tested for flow and blood pressure to ensure it is functioning properly.
- Once the procedure is complete, the patient is kept in a recovery room to be monitored until they are fully awake.
Risk of AV Fistula Surgery
The risks of AV fistula surgery include the following:
- Bleeding
- Infection
- Injury to surrounding structures.
- Blood clots
- Numbness
- Swelling
- Pain at the surgical site.
Recovery of AV Fistula Surgery
- After the procedure, patients will need to keep the surgical site clean and covered.
- They may also need to avoid heavy lifting and using the arm for several weeks.
- Physical therapy may be recommended to help improve mobility and strength in the arm.
- Most patients can return to their normal activities within a few weeks of the procedure.
- It is important to remember everyone's recovery from AV fistula surgery is unique and may take longer for some individuals.
- Follow the doctor's instructions and attend all follow-up appointments to ensure a successful outcome.
Frequently Asked Questions
How long does AV fistula surgery take?
AV fistula surgery typically takes 1-2 hours or more to complete, depending on the extent of the condition.
How long does it take to recover from AV fistula surgery?
Recovery from AV fistula surgery typically takes 4-6 weeks.
Is AV fistula surgery high risk?
AV fistula surgery is generally considered to be a low-risk procedure. However, there are risks associated with any surgical procedure.
Can an AV fistula be removed?
Yes, an AV fistula can be removed if it is no longer needed or is causing complications. This is typically done through a surgical procedure that closes off the fistula and allows the incision to heal.
How long can you live on dialysis?
The length of time someone can live on dialysis depends on several factors, including their overall health, age, underlying medical conditions, and lifestyle factors.
What causes AV fistula to fail?
AV fistulas can fail for a variety of reasons, including thrombosis (formation of a blood clot in the fistula), stenosis (narrowing of the fistula), infection, pseudoaneurysm (a bulge in the wall of the fistula) or arterial insufficiency (decreased blood flow to the arm).
How many years does a fistula last?
The lifespan of an AV fistula varies depending on a number of factors, like the patient's overall health and the quality of care and maintenance of the fistula.
