What type of line is inserted into arm for dialysis?

For dialysis, a type of line called a central venous catheter (CVC) is often inserted into the arm. This catheter allows for easy access to the bloodstream for the dialysis process. It typically has two lumens to facilitate the removal and return of blood during treatment. In some cases, a fistula or graft may be created for long-term access, but a CVC is commonly used for short-term needs.
