A central venous catheter (CVC), also called a central line, is a long, thin, flexible tube used to give medicines, fluids, nutrients, or blood products over a long period of time, usually several weeks or more. The catheter makes doing these things more comfortable for you because they are put directly into the catheter. You are not poked with a needle every time. The catheter may be used to draw blood for tests only if another vein, such as in the hand or arm, can't be used.
The CVC is inserted in your arm, chest, neck, or groin. It is put through the skin and into a large vein. The catheter is threaded through this vein until it reaches a large vein near the heart. In most cases, the other end of the catheter—the end used to give medicines—sticks out of the skin.
