Subcutaneous (under the skin) or Implantable Lines

This type of central line is usually referred to as a medi-port or port-a-cath. Unlike a Hickman, an implantable port is completely under the skin.

This type of catheter is surgically implanted, usually in your chest but some teens have them in their arms. Most teens have general anesthesia for this procedure. One end of the catheter is fed into a large vein leading directly into your heart. The other end is attached to a small chamber called a portal. The portal is made of either metal or plastic with a rubber top that seals it and is placed under your skin.

You will feel a small bump under your skin where the portal has been placed. When you need to use your port, it is accessed with a special needle (a Huber needle) that has a tube attached to it. Your meds or whatever will flow through the needle, into the catheter and then into your bloodstream.

After a while, the skin over your port becomes very tough and insensitive. You can also use EMLA cream to numb the area.

How Do I Take Care of My Line?

Subcutaneous catheters (or medi-ports, port-a-caths) are easier to maintain than external lines. They need to be flushed with a heparin solution to prevent clotting but usually only once a month or after each use. There is no worry about swimming, bathing or showering with this system. Normal activities can be continued.
