A dialysis fistula that loses its buzz, swells, bleeds for long after needling or causes a cold, painful hand needs same-week review. Many problems, such as narrowing or aneurysm, can be repaired to save the access. Patients from Valsad can plan an assessment in Surat around dialysis days with Dr. Ashutosh Shah's team.
My dialysis fistula stopped working, what should I do? Call your dialysis unit the same day. A fistula that has lost its buzz may have clotted, and the sooner it is treated, the better the chance of saving it. An arteriovenous (AV) fistula is a surgical joining of an artery and a vein, usually in the arm, which becomes your lifeline for dialysis. This guide explains the daily check, the warning signs of a dialysis fistula not working, which problems can be repaired, and how patients from Valsad can plan a visit.
How do you check a fistula at home every day?
By looking, listening and feeling, once every day and before every dialysis session. The National Kidney Foundation advises checking the access daily, and the KDOQI vascular access guideline describes the same examination: inspection, feeling and listening.
Daily fistula self-check checklist
- Look: compare both arms. Check for redness, new swelling, shiny or thinning skin, scabs that do not heal, or bulges that are growing.
- Listen: hold the fistula arm near your ear, or use a stethoscope if you have one, for a steady whooshing sound.
- Feel: rest your fingers gently over the fistula. You should feel a buzz or vibration, called the thrill.
- Check the hand: it should be warm, with normal colour and feeling, and no new pain or numbness.
- Protect the arm: no blood pressure cuffs, blood tests or drips in that arm unless your dialysis team agrees, no tight watches or bangles, and do not sleep on it.
Which signs mean the fistula is failing or in danger?
A weaker or absent buzz, new swelling, bleeding that lasts much longer than usual after needles are removed, a bulge with thin or shiny skin, or a cold, painful or numb hand. These are the signs the NKF and the KDOQI guideline highlight, and each has a likely cause.
| Sign | Likely cause | Urgency | Typical fix |
|---|---|---|---|
| No buzz or sound | Clot (thrombosis) | Same day | Clot removal and treatment of the narrowing behind it, ideally within 24 to 48 hours |
| Weaker buzz, poor dialysis flow | Narrowing (stenosis) | Within the week | Balloon angioplasty or surgical revision |
| Bleeding for long after needling (AV fistula bleeding) | Narrowing downstream, raising pressure | Within the week; emergency if it will not stop | Treat the narrowing; review needling sites |
| Arm or hand swelling | Narrowing in a larger vein closer to the chest | Within the week | Imaging, then angioplasty of the central vein |
| Growing bulge with thin, shiny skin or scabs | Aneurysm at risk of rupture | Urgent, same week | Surgical repair or reconstruction of the segment |
| Cold, pale, painful or numb hand | Steal syndrome, where the fistula takes blood away from the hand | Urgent if worsening | Surgery to reduce flow or redirect blood to the hand |
| Redness, warmth, pus or fever | Infection | Same day | Antibiotics; surgery if an abscess forms |
Emergency: if the fistula bleeds heavily and does not stop with firm pressure for 10 to 15 minutes, keep pressing with clean gauze and go to the nearest emergency department.
Is swelling in an AV fistula dangerous?
It can be. AV fistula swelling of the whole arm usually means a narrowing in a vein closer to the chest, which needs imaging and treatment. A localised bulge is usually an aneurysm, which is safe to watch only while the skin over it stays thick and healthy. Thin, shiny or scabbed skin over a bulge needs urgent review because of bleeding risk.
What can be repaired and what needs a new access?
Most problems caught early can be repaired, so the same fistula keeps working. A new access is made only when the existing one cannot be saved. Dialysis access procedures fall into three groups.
- Repair through the vein (endovascular): a balloon is passed into the narrowed segment and inflated to widen it, called angioplasty. Clots can also be removed this way.
- Open repair: AV fistula surgery to bypass or remove a narrowed segment, reconstruct an aneurysm, reduce excess flow, or treat steal syndrome.
- New access: a new fistula higher in the arm or in the other arm, or a graft, which is a soft tube joining artery and vein. A temporary catheter may be needed meanwhile.
The surgical principles are similar to other vein operations, which are explained in Vein surgery explained. Each option is planned with your nephrologist, the kidney specialist who manages your dialysis.
Can a failed fistula be repaired?
Often, yes, especially if it is treated quickly. A fistula that has clotted in the last day or two can frequently be reopened. One that has been blocked for longer, or has repeated problems despite repairs, may need a new access. The decision depends on imaging and the state of the vessels.
How is surgery timed around dialysis sessions?
Around your existing schedule, so you do not miss treatment. Most planned access procedures are booked on a non-dialysis day, often the day after a session, when fluid and potassium levels are best controlled.
- Before: recent blood reports, your dialysis timetable and a list of medicines, including blood thinners.
- The procedure: usually under local anaesthesia, as a day procedure for most repairs.
- After: dialysis usually continues on schedule, through the repaired fistula if it is ready or a temporary catheter if not.
- A new fistula: needs time to mature before it can be used, which the NKF describes as weeks to months.
Coordination rule: no access procedure is planned without your nephrologist. Dr. Ashutosh Shah's team works with your nephrologist and, where needed, interventional colleagues, so that dialysis, blood thinners and the timing of the new access are agreed by everyone before surgery.
How can patients from Valsad plan the visit? Dialysis fistula repair in Valsad: planning around dialysis days
By sending reports first and booking the visit on a non-dialysis day. Elegance Clinic is in Surat; there is no branch in Valsad, so most patients plan one assessment visit, then the procedure, with dialysis continuing at their usual unit.
- Send reports first: dialysis unit notes, any Doppler scan, and recent blood tests.
- Book a non-dialysis day for the assessment, ideally early in the day.
- Bring your dialysis timetable so the procedure date fits your sessions.
- Plan travel and stay: see Travelling to Surat for treatment.
- Ask about costs early: see EMI and payment options.
In our practice, patients from South Gujarat who come in early, when the buzz first weakens, very often keep their fistula. Those who wait until it has been silent for days more often need a new access.
Next step: a dialysis fistula not working properly is easier to save early. If yours is not working as before, do not wait for it to fail completely. Contact the clinic with your reports and dialysis timetable.

FAQs
Why has my fistula stopped buzzing?
Usually because blood has clotted inside it, often behind a narrowing that was slowly reducing flow. Low blood pressure, dehydration or pressure on the arm can trigger it. Call your dialysis unit the same day, because a fistula treated within a day or two can often be reopened.
Is a swollen fistula dangerous?
It can be. Swelling of the whole arm suggests a narrowed vein nearer the chest. A localised bulge with thick, healthy skin can often be watched, but a bulge with thin, shiny or scabbed skin risks bleeding and needs urgent review. Any new or growing swelling should be checked within the week.
Can a blocked fistula be opened again?
Often, yes, if treated quickly. The clot is removed and the narrowing that caused it is treated, either through the vein with a balloon or by open surgery. The longer a fistula stays blocked, the lower the chance of saving it, so do not wait for the next dialysis session.
How long before a new fistula can be used?
A new fistula needs time to grow stronger and wider before needles can be used, usually around six to eight weeks or longer. The National Kidney Foundation describes this as weeks to months. A graft can usually be used sooner. Your team checks maturity by examination and sometimes a scan.
Can I lift weights with a fistula arm?
Gentle hand and arm exercise, such as squeezing a soft ball, helps a new fistula mature. Avoid heavy lifting, carrying heavy bags on that arm and anything that presses on the fistula. Ask your dialysis team before starting weight training, and never wear tight bands or straps over it.
Should dialysis be missed for fistula surgery?
No. Surgery is planned around your sessions, usually on a non-dialysis day, and dialysis continues afterwards through the fistula or a temporary catheter. For dialysis fistula repair in Valsad patients can share their timetable in advance so the procedure date fits without missing treatment.
