There are several types of venous access available for dialysis:
- AV fistula: ideal because blood vessels have had time to heal and scar over.
- AV graft: less mature than a fistula, but still pretty good
- Dialysis catheter: any one of various tubing used to establish venous access
- tunneled line (Hickman): as the name implies, tunnels under the skin to the subclavian and can last for months to years
- Perm-a-cath (vascath): fancy name for a central line. This is probably the least favorable option because it may work for several months before failing and is associated with higher rates of infection
As a reference, here is this handy, concise guide on catheters from the ACP.
