A tunneled line is a type of central access which is inserted under the skin, and then travels a significant distance through surrounding tissue before reaching and penetrating the central vein. Using a tunneled line reduces the risk of infection as compared to other forms of access, as bacteria from the skin surface are not able to travel directly into the vein. These catheters are often made of materials that resist infection and clotting. Types of tunneled central lines include the Hickman line or Broviac catheter. A tunnelled line is an option for long term venous access necessary for hemodialysis in people with poor kidney function.
