Which site is appropriate for PICC placement in the upper extremity?

The basilic vein is a suitable site for peripherally inserted central catheter (PICC) placement in the upper extremity due to its anatomical location and characteristics. It is a large vein that runs along the inner aspect of the arm, offering ample space for catheter insertion. The basilic vein typically has good access and a larger diameter, which makes it ideal for accommodating the catheter, resulting in reduced risk of complications such as kinking or blockage. Additionally, its position provides a longer pathway to the central venous system, which is essential for the intended uses of a PICC line.

In contrast, the other options do not serve as appropriate sites for PICC placement in the upper extremity. The saphenous vein, primarily located in the lower extremities, is not suitable for upper extremity catheter placement. The popliteal vein, also located in the leg behind the knee, is not accessible from the arm and does not contribute to upper extremity access. Although the cephalic vein is an alternative site in the upper extremity, it is smaller and may have a higher incidence of complications when compared to the basilic vein, making the basilic vein a preferred choice for PICC insertions.
