Central lines are long, hollow tubes made from silicone rubber. They are also called skin-tunnelled central venous catheters. They are used to give chemotherapy treatment or other medicines.
Some catheters that are used are Hickman® or Groshong®. Hickman and Groshong are registered trademarks of CR Bard Inc, or an affiliate.
The central line is put in (tunnelled) under the skin of your chest and into a vein close by. One end of the line goes into a large vein just above your heart. The other end comes out of your chest.
The line is usually sealed with a special cap or bung. This can be attached to a drip or syringe containing your medication. There may be a clamp to keep the line closed when it’s not being used.
Sometimes the central line divides into a further 2 or 3 lines. This allows you to have different treatments at the same time.
