A central venous catheter (CVC) is frequently used today for patients who cannot have a permanent vascular access to hemodialysis. Fistula formation may not be possible in cases where the blood vessels of the patients are unsuitable or very sensitive. In this case, a central venous catheter is preferred for emergency vascular access. For hemodialysis treatment, CVC can be performed by the surgeon by placing carotid artery, subclavian vein or femoral vein catheter.
With CVC, immediate access to the circulation system can be achieved. Patients using CVC can move their hands and arms freely during dialysis and no needle intervention is made through the fistula.
