Central Vascular Access Device (CVAD)

Table of Contents


Overview

What is a central vascular access device (CVAD)?

A CVAD is a thin, flexible tube. It's also called a central line. It is used when a person needs to receive medicine, fluids, nutrients, or blood products for several weeks or more. It's often placed in the neck, chest, or arm.

Why is it used?

CVADs are used to:

A CVAD may be used to draw blood for tests only if another vein, such as in the hand or arm, can't be used.

It may also be used to check blood flow in the heart and body.

What are the types of central vascular access devices?

There are several types of CVADs.

PICC line.

A peripherally inserted central catheter, or PICC line (say "pick"), is a CVAD inserted into a vein in the arm rather than a vein in the neck or chest.

Tunneled catheter.

This type of catheter is surgically inserted into a vein in the neck or chest and passed under the skin. One end of the catheter remains outside the skin. Medicines can be given through an opening in this end of the catheter. Passing the catheter under the skin helps keep it in place better, lets you move around easier, and makes it less visible.

Implanted port.

This type is similar to a tunneled catheter but is left entirely under the skin. Medicines are injected through the skin into the catheter. Some implanted ports contain a small reservoir that can be refilled in the same way. After being filled, the reservoir slowly releases the medicine into the bloodstream. An implanted port is less obvious than a tunneled catheter and requires very little daily care. It has less impact on a person's activities than a PICC line or a tunneled catheter.

What are the risks?

Possible risks from the use of a CVAD include:
