When your kidneys no longer function well, dialysis becomes your lifeline. But did you know the success of your dialysis depends on something called an AV fistula? If you’re in Bangalore and have been advised to undergo AV fistula surgery, it’s normal to feel anxious. This guide—crafted by Dr. Sravan, leading Vascular & Endovascular Surgeon in Bangalore—will walk you through every step of what to expect and how to prepare.
Let’s simplify the journey, answer your questions, and help you make confident decisions about your vascular care.
What Are the Common Symptoms That Indicate You May Need an AV Fistula?
While AV fistulas are typically planned before dialysis begins, certain warning signs may lead your doctor to recommend it:
-
Chronic kidney disease or low eGFR (≤15 mL/min)
-
Repeated swelling in your arms or legs
-
Weakness, fatigue, or confusion linked to poor kidney filtration
-
Long-term planning for dialysis access
-
Frequent IV injections making veins less usable
Unlike sudden emergencies, AV fistula creation is a proactive step. Early planning ensures your body adapts well before dialysis starts.
What Causes the Need for AV Fistula Surgery in the First Place?
The need for an AV fistula stems from kidney failure. When kidneys can’t clean your blood anymore, dialysis takes over. But dialysis requires strong, reliable blood flow—and regular veins simply can’t handle the pressure.
Here’s why an AV fistula is the gold standard:
-
Stronger Blood Flow: It connects an artery and a vein, creating a high-pressure access point.
-
Lower Infection Risk: Unlike catheters, it’s under your skin.
-
Long-Lasting: With proper care, it can last for years.
In Bangalore, patients with chronic kidney disease are increasingly opting for AV fistulas under the care of vascular experts like Dr. Sravan to avoid complications and repeat procedures.
How Is AV Fistula Surgery Performed?
AV fistula creation is a minor surgical procedure, usually done under local anesthesia.
Here’s what happens step-by-step:
-
Consultation & Mapping – The surgeon examines your arm veins using Doppler ultrasound.
-
Surgical Creation – An artery and nearby vein (usually in your non-dominant arm) are connected.
-
Recovery & Maturation – The fistula needs 4–8 weeks to “mature” so it’s strong enough for dialysis.
-
Monitoring – You’ll be guided on how to check the fistula daily (feeling a vibration or “thrill”).
The surgery is usually completed within 1–2 hours, and patients return home the same day.
How Can You Prepare for AV Fistula Surgery in Bangalore?
Preparation is key to long-term success. Here’s what Dr. Sravan recommends:
-
✅ Choose the Right Arm Early: Use your non-dominant arm and avoid blood draws or BP checks on it.
-
✅ Inform Your Dialysis Center: Coordination ensures your access is ready when needed.
-
✅ Stay Hydrated: It helps with vein visibility and post-op healing.
-
✅ Avoid Blood Thinners (If Advised): Temporarily stop aspirin or anticoagulants as guided.
-
✅ Arrange Help Post-Surgery: Minimal activity is advised for the first 24–48 hours.
In Bangalore’s humidity, cleanliness is crucial. Keep the wound area dry, avoid submerging your arm in water, and follow hygiene practices as instructed.
When Should You Consult a Vascular Surgeon Like Dr. Sravan?
Timing is everything when it comes to dialysis planning. You should consult a vascular surgeon if:
-
Your nephrologist has discussed dialysis as an upcoming option.
-
You have stage 4 or stage 5 chronic kidney disease.
-
Your temporary catheter keeps getting infected or clogged.
-
You’re planning pre-emptive fistula creation to avoid last-minute complications.
Dr. Sravan’s clinic in Basavanagudi offers detailed vein mapping, patient counseling, and early AV access planning—ensuring your dialysis journey is smooth from day one.
FAQs About AV Fistula Surgery
Is AV fistula surgery painful?
The procedure is done under local anesthesia. You may feel mild soreness for 2–3 days, but it’s manageable with prescribed pain relief.
How soon can I use the AV fistula for dialysis?
Usually after 4–6 weeks, once the fistula matures. Your surgeon will evaluate and approve it before first use.
What are signs that my AV fistula isn’t working properly?
Look out for absence of vibration (thrill), swelling, redness, or difficulty during dialysis. Report these immediately.
Can I exercise or lift weights after fistula surgery?
Avoid strenuous arm activity for at least 2 weeks. Gentle movement is fine but always follow your surgeon’s instructions.
What if I delay getting an AV fistula?
Delaying can lead to emergency dialysis with a catheter—which has higher infection risks. Planning early keeps you safe and stable.
