What does the medical abbreviation picc mean?

PICC stands for "peripherally inserted central catheter". It is a type of long, thin tube that is inserted into a vein in the arm and threaded into a large vein near the heart. PICC lines are used to deliver medications, fluids, and nutrition directly into the bloodstream. They are often used for patients who need long-term IV therapy, such as those with cancer or HIV/AIDS.
