Interventional Procedures on Hemodialysis Access (Thrombectomy, Angioplasty, Stenting)

Minimally invasive treatments to restore and maintain proper blood flow in dialysis access sites.

What are Interventional Procedures on Hemodialysis Access?

These procedures are performed to treat blockages or narrowing in the blood vessels used for hemodialysis access (such as arteriovenous fistulas or grafts). Using imaging guidance, doctors can restore blood flow and keep the access functioning, which is essential for ongoing dialysis treatment.

These treatments help to:

Remove blood clots that block dialysis access (thrombectomy)

Widen narrowed vessels using a balloon (angioplasty)

Place a small mesh tube (stent) to keep the vessel open

Ensure reliable blood flow for dialysis sessions

Prolong the lifespan of the vascular access

What to expect during the procedure?

Performed in a hospital or outpatient interventional radiology suite

Local anesthesia and mild sedation are typically used

A catheter is inserted through a small incision to access the vessel

Imaging (X-ray or ultrasound) guides the procedure

Most patients go home the same day

Mild soreness or bruising at the insertion site may occur

Why is it performed?

To restore dialysis access when blood flow is reduced or blocked
To treat clots that prevent effective dialysis
To manage narrowing (stenosis) that causes poor access function
To reduce complications such as swelling, pain, or prolonged bleeding after dialysis
To avoid surgical replacement of the access whenever possible

Risks and Considerations

Risk of infection at the access site
Bleeding or bruising at the puncture site
Rare damage to the blood vessel
Risk of recurrence, requiring repeat procedures
Requires ongoing monitoring of dialysis access function

Early detection is important for managing the condition and preventing further complications.

FAQs

Is the procedure painful?

Most patients feel little or no pain, as local anesthesia and sedation are used.

How long does it take?

Usually 1–2 hours, depending on the complexity of the access problem.

Can I resume dialysis right after?

In many cases, dialysis can be performed the same or next day.

Do these procedures replace surgery?

Often yes, they can delay or prevent the need for surgical access replacement.

How often might I need this treatment?

It depends on the patient—some may need repeat procedures if blockages reoccur.
