Pediatric Tunneled Central Venous Catheter

A tunneled central line is a catheter (a thin tube) that is placed in a vein for long term use. It is most commonly placed on the chest and tunnels under the skin upward toward the neck, then into the blood vessel that carries blood to the heart. The catheter is tunneled under the skin. It has a cuff attached to it that allows tissue and skin to grow around it, giving the line more stability.
