The veins in your arms are called peripheral veins. That simply means they're not in the center part of your body. A catheter inserted into a peripheral vein and guided to a central vein is called a peripherally inserted central catheter. It's also called a PICC line. PICC line placement involves inserting a PICC line into a large blood vessel that leads to your heart.
