Which vein is commonly accessed for a PICC line insertion?

The basilic vein is commonly accessed for Peripherally Inserted Central Catheter (PICC) line insertion due to its favorable anatomical position and size. This vein is located in the upper extremity, specifically along the inner aspect of the arm, and is often large enough to accommodate the PICC line, which may facilitate ease of insertion and improve the stability of the catheter.

Choosing the basilic vein for PICC line placement is advantageous because it is typically less mobile than other veins, such as the superficial veins, which can be more prone to movement and dislodgement. Additionally, the basilic vein has a direct route to the central venous system, allowing for optimal central venous access and minimizing the risk of complications associated with deeper vein access.

While other veins like the jugular or subclavian are also used for central line placements in general, they are less commonly utilized for PICC lines specifically. The femoral vein, although accessible, is generally reserved for temporary access due to higher risks of complications like infection and thrombosis. Hence, the basilic vein is favored for this procedure, making it the correct choice.
