Using a central venous catheter for dialysis access is associated with a higher risk of infection and thrombosis, making this the notable risk linked to this type of access. Central venous catheters, while often a necessity for immediate dialysis in certain patients, do not have the same levels of safety features as other access methods like arteriovenous fistulas or grafts. This is primarily due to their placement in large veins, which increases exposure to systemic circulation and the risk of bacterial colonization.

In terms of infection, the catheter can become a direct pathway for pathogens to enter the bloodstream, leading to conditions such as bacteremia or sepsis. Furthermore, the risk for thrombosis arises because the catheter can disturb blood flow dynamics in veins and promote clot formation, especially if the catheter remains in place for extended periods or is not managed properly.

This increased risk profile is a significant consideration for healthcare professionals when determining the most appropriate access method for dialysis, highlighting the need for careful infection control practices and monitoring in patients with central venous catheters.
