Dialysis Access at CritiCare Asia Hospitals, Juhu
For patients with kidney failure requiring haemodialysis, reliable vascular access is essential. Dialysis cannot proceed safely without a route that allows blood to be withdrawn, filtered, and returned to the body repeatedly, often several times a week. CritiCare Asia Hospitals' vascular surgery team works closely with the nephrology team to plan and create durable dialysis access suited to each patient's vascular anatomy and treatment timeline. Consult our specialists to learn more about AV fistula treatment in Juhu, Mumbai. Access planning is not a last-minute step; it is ideally addressed well before a patient's kidney function declines to the point where dialysis becomes necessary, since a fistula needs time to mature before it can be used safely.
AV Fistulas
An arteriovenous (AV) fistula is a surgically created connection between an artery and a vein, usually in the arm, that allows the vein to widen and strengthen under arterial blood flow over time. This "maturation" process typically takes several weeks to months before the fistula is ready for use in dialysis. Once matured, an AV fistula surgery provides a durable access point capable of withstanding repeated needle insertion over years of dialysis treatment.
AV fistulas are generally considered the preferred form of dialysis access where a patient's vein anatomy allows it, owing to their comparatively lower rates of infection and clotting relative to other access types such as grafts or catheters. Not every patient is a suitable candidate, however. Factors the vascular team considers before planning a fistula include:
- Vein size and quality
veins need adequate diameter and healthy walls to withstand arterial pressure and repeated needling - Artery condition
sufficient arterial inflow is needed to support fistula maturation - Overall vascular health
conditions such as diabetes or peripheral vascular disease can affect suitability. - Arm dominance and lifestyle
access site selection accounts for which arm is non-dominant where possible, to minimise disruption to daily activities
Consult experienced AV fistula specialists at CritiCare Asia Hospitals for detailed evaluation and guidance.
Planning and Creation
Before an AV fistula creation, the surgical team first evaluates the patient's arteries and veins, often through ultrasound mapping. This helps identify a suitable site and confirms whether a fistula is feasible at all. The procedure is usually done under local anaesthesia, with the surgeon joining the chosen artery and vein directly.
After surgery, the fistula is monitored by dialysis access surgeons to see that it's maturing properly, and the access site needs care to keep infection and clotting at bay. Patients are also shown how to check the fistula themselves at home - mainly by feeling for the "thrill," a vibration that signals healthy blood flow through the site.
Complications and Monitoring
AV fistulas are a vascular access surgery which need continuous monitoring. A few things can go wrong:
- Some fistulas simply fail to mature, never widening or strengthening enough to support hemodialysis access needling
- Stenosis can develop - a narrowing at or near the connection site that cuts down blood flow
- Clotting, or thrombosis, blocks the fistula outright and stops it functioning
- Infection at the access site needs prompt treatment when it occurs
- Repeated needling over time can also cause aneurysm formation, where the vein wall bulges locally
Regular check-ups allow the vascular team to identify and address these issues early, helping preserve the fistula's function for as long as possible and reducing the need for repeated access procedures. Where problems are detected, interventions such as angioplasty or revision surgery may be considered depending on the nature of the complication.
