PICC lines (peripherally inserted central catheters) are used to give someone chemotherapy treatment or other medicines.
A PICC line is a long, thin, flexible tube called a catheter. It’s put into one of the large veins of the arm, above the bend of the elbow. Then it is threaded into the vein until the tip is in a large vein just above the heart.
The line is usually sealed with a special cap or bung. This can be attached to a drip or syringe containing your chemotherapy or medication. There may be a clamp to keep the line closed when it’s not being used.
Sometimes it divides into two or three lines. This allows you to have different treatments at the same time.
