Dialysis and Access Interventions are minimally invasive procedures performed to improve or restore blood flow in a fistula and AV grafts dialysis patients. Dialysis and Access Intervention may be recommended to treat:

1. Narrowing of veins or blood vessels attached to dialysis fistula or grafts. When there is decreased function in a graft or fistula, angioplasty or other techniques that may involve stenting may be used.

2. Thrombosis of dialysis fistulas or grafts. When blood does not flow smoothly or there is a narrowing in the AV access, it can begin to slow and ultimately coagulate or clot.  When blood clots in a fistula or graft dialysis, catheter-directed thrombolysis with clot-dissolving drugs and techniques may be performed to re-establish flow.

In these procedures, X-ray imaging equipment and specialized equipment that can aid in restoring blood flow will be used. This equipment may include balloon catheters, guide wires, sheaths, stents and other medical devices that can dissolve clots mechanically.

Dialysis Access

Stents are specially designed metal tubes that are inserted into the body and then expanded inside the vessel to help as a scaffolding for blood vessels that may be narrowed. A stent may be placed to hold the vessel open.

Dialysis AccessA blood clot can be dissolved in a few ways, including a combination of delivering clot-dissolving medication directly to the blood clot and/or positioning a mechanical device at the site to break up the clot.
