Central Line Inserted Central Catheter
A central catheter is a long, thin tube that is inserted into a large vein. A central catheter is used to deliver medication, nutrition, IV fluids, and chemotherapy.
There are different types of central catheters, including:
- Peripherally inserted central catheter (PICC line)—The catheter is threaded through a vein in the arm until it reaches the larger vein close to the heart.
- Non-tunneled central catheter—It is inserted in a large vein in the neck or leg; the tube end is outside of the skin.
- Tunneled central catheter—It is inserted in the neck vein and tunneled under the skin. The end of the catheter is sticking out from under the skin, usually below the collarbone.
- Port catheter—It is inserted in a shoulder or neck vein. The port is under the skin, and the catheter is tunneled into the central vein. The port is accessed by putting a needle through the skin directly into the port.

Central catheters are inserted when patients need:
- Long-term medication or fluids
- Nutrition, but cannot get it through the digestive system
- Repeated blood draws
- Blood transfusions
- IV medications when arm veins are difficult to access
A central catheter is commonly inserted by special types of doctors called interventional radiologists or vascular surgeons. Once the line is in, it can be used for weeks to months.
