What type of catheter is a PICC?

A peripherally inserted central venous catheter (PICC) is a specialized type of catheter used for extended venous access. It is inserted into a peripheral vein, typically in the arm, and threaded through to a central vein near the heart, allowing for the delivery of medications, nutrients, and blood products, or for blood sampling.

This type of catheter is particularly beneficial for patients who require long-term intravenous therapy (greater than a week), as it minimizes the risks associated with repeated venipuncture. The PICC can remain in place for weeks to months, making it an ideal choice for patients undergoing treatments such as chemotherapy or extended antibiotic therapy.

Understanding the structure and function of a PICC compared to other catheter types helps clarify its unique role in intravenous therapy. The distinction between PICC and other options, such as short peripheral catheters or midline catheters, lies in its ability to access central veins for high-flow or irritating medications, which those other types do not accommodate effectively.
