Dialysis Access Surgery

AV Fistulas, Grafts, Catheters and Revision Procedures (Open and Endovascular)

Dialysis access is essential for effective treatment. When it becomes narrow, blocked, or infected, dialysis flow and comfort are affected.

Dr. Abuazab provides complete access care-including AV fistulas, grafts, catheters, and advanced repair procedures-to ensure reliable, long-lasting function.

Early evaluation prevents complications and keeps your dialysis running smoothly.

When Dialysis Access Care Is Needed

Patients may require evaluation or intervention if they experience:

Poor dialysis flows or repeated machine alarms
Swelling or pain in the arm with the fistula or graft
High venous pressures during dialysis
Difficulty inserting needles
Narrowing or hardening felt along the vein

Prolonged bleeding after needle removal
Infection in the access site
A blocked or failing access
Need for a new permanent access for dialysis

Even early signs of dysfunction should be assessed promptly to avoid sudden access failure.

Types of Dialysis Access Offered

AV Fistula (Arteriovenous Fistula)

An AV fistula is the preferred and most durable form of dialysis access. It is created by joining an artery and a vein, allowing the vein to become stronger and larger over time. This provides an access point that is reliable and long-lasting.

Benefits include:

Lowest risk of infection
Long lifespan
Better blood flow for efficient dialysis
Reduced risk of clotting

AV Graft (Arteriovenous Graft)

A graft is used when veins are not suitable for a fistula. A soft synthetic tube connects the artery and vein to provide an access site.

Benefits include:

Faster readiness for use
Suitable for patients with small or weak veins
Reliable option when fistulas are not possible

Dialysis Catheters

Catheters are placed when immediate dialysis access is required. They are inserted into a large vein, often in the neck or chest.

Used for:

Emergency dialysis
Temporary access while a fistula matures
Patients who cannot undergo fistula or graft surgery

Catheters are not a long-term solution and require careful monitoring.

Maintenance and Revision of Access

Over time, access points can develop narrowing or clotting. Dr. Abuazab performs both minimally invasive and open procedures to restore function.

Endovascular Procedures

Balloon angioplasty to widen narrow areas
Stent placement to maintain long-term flow
Thrombectomy or clot removal
Catheter-directed medication delivery

Benefits include:

Small puncture instead of incision
Quick recovery
Immediate improvement in flow
Short hospital stay

Open Surgical Revision

For complex cases or repeated access failure, open surgery may be needed to repair or reconstruct the access.
Benefits include:

Durable long-term solution
Effective for complex or recurrent problems
Improved access flow and stability

Early intervention helps prevent sudden access loss and reduces the need for emergency catheters.

How Treatment Improves Dialysis Quality

Restoring or creating a functional dialysis access helps you experience:

Smoother and more efficient dialysis sessions
Better clearance results
Fewer interruptions or alarms
Reduced risk of infections and complications
Improved long-term treatment stability

When your access functions well, your overall dialysis experience becomes safer and more comfortable.
