Peripherally Inserted Central Catheter
A peripherally inserted central catheter is a long, thin tube that is inserted through a vein in the arm. The catheter is threaded through the arm vein until it reaches a larger vein close to the heart. This is commonly called a PICC line.

PICC lines may be used if you need:
- Long-term medication treatment and cannot take medication by mouth
- Fluids—if you cannot drink enough to stay hydrated
- Calories that you cannot get by eating
- IV medication—if arm veins are hard to find or use
After the PICC line is in, it can be used for weeks to months.
