When dialysis access fails, treatment stops.
A working AV fistula or graft is the difference between a clean four-hour dialysis run and a trip to the emergency room. Dr. Anton is one of the few interventional nephrologists in South Florida dedicated to keeping dialysis access open.
Why access problems are urgent
Hemodialysis depends on a reliable connection between the bloodstream and the dialysis machine — most often through an AV fistula (a surgical connection between an artery and a vein) or an AV graft (a synthetic bridge between the two). These access sites are remarkable, but they're also under constant mechanical stress. Over time, they narrow, clot, or fail.
When access fails, dialysis can't happen safely. Patients end up in the ER, often with a temporary catheter — which carries a much higher infection risk than a fistula or graft.
Every avoided catheter day is a day of safer dialysis.
The good news: most access problems are caught early through routine monitoring, and almost all are correctable in a single outpatient procedure. Speed matters — the sooner we restore flow, the longer the access lasts.
What to watch for in your fistula or graft
A dedicated dialysis access specialist.
Dr. Anton is a board-certified interventional nephrologist — a small subspecialty trained specifically to maintain and rescue dialysis access. He completed UNOS-certified transplant nephrology fellowship training at Case Western Reserve and has spent over 20 years caring for kidney patients. He understands what dialysis takes out of a person and how protecting access preserves quality of life.
Our Pompano Beach office sits within a short drive of five dialysis centers. We coordinate directly with dialysis units so referrals move fast and patients don't miss treatment.
Same-day procedures, less catheter time
Most access problems are diagnosed in the office with a duplex ultrasound and treated the same day. Narrowed segments are opened with angioplasty; clotted accesses are declotted; failing outflow veins are angioplastied to restore pressure. All procedures use local anesthesia and a small needle puncture — no general anesthesia, no overnight stay.
Patients typically go home within hours and can dialyze on schedule the next day. We maintain a watchful eye on the access with periodic surveillance to catch new narrowings before they cause another emergency.
Frequently asked questions
Why are dialysis access problems urgent?
A working AV fistula or graft is essential for safe dialysis. When access narrows, clots, or fails, dialysis can't happen safely and patients often end up in the ER with a temporary catheter, which carries a much higher infection risk.
What are the warning signs my fistula or graft is failing?
A weakened or absent thrill (vibration), a changed bruit (whooshing sound), difficulty placing needles, prolonged bleeding after dialysis, arm or hand swelling, cold or numb fingers, or reduced dialysis efficiency.
Can a failing dialysis access be fixed?
Yes — most access problems are caught early through monitoring and are correctable in a single outpatient procedure. The sooner flow is restored, the longer the access lasts.
What does treating dialysis access involve?
Most problems are diagnosed in-office with a duplex ultrasound and treated the same day: narrowed segments are opened with angioplasty and clotted accesses are declotted, all under local anesthesia with a small needle puncture.
How quickly can I get back to dialysis?
Patients typically go home within hours and can dialyze on schedule the next day, with periodic surveillance to catch new narrowings early.
