A central venous catheter is a tube that goes into a vein in your chest and ends at your heart. Sometimes this type of catheter is attached to a device called a port that will be under your skin. The port and catheter are put in place in a minor surgery. The catheter helps carry nutrients and medicine into your body. It will also be used to take blood when you need to have blood tests.
