Types of Dialysis Catheter

Arteriovenous Fistula (AV Fistula)
Arteriovenous Fistula (AV Fistula)

There are three types of access: catheter, arteriovenous (AV) graft and arteriovenous (AV) fistula. Catheter for hemodialysis. For dialysis, a catheter is inserted into a large vein in either the neck or chest. A catheter is usually a short-term option; however, in some cases a catheter is used as a permanent access.

Arteriovenous Graft (AV Graft)
Arteriovenous Graft (AV Graft)

An AV graft doesn’t last as long as an AV fistula does. Unlike with a catheter, needles are still required to access the AV graft. AV grafts are more prone to clotting than AV fistulas are. v; For some people, AV grafts are the best option for dialysis access.

Central Venous Catheter (CVC)
Central Venous Catheter (CVC)

Central venous catheters (CVC) for hemodialysis may be nontunneled (designed for acute episodes and temporary duration) or tunneled (for more chronic use over a longer duration). Acute CVC are designed to be placed with a minimum amount of effort. They generally have double lumens, no subcutaneous cuff or locking device and utilize a short linear tunnel.
