What is the preferred CVAD placement site and why?

• A. Femoral - easier access
• B. Jugular - commonly used
• C. Subclavian - lower risk for infection
• D. External - minimal obstruction

Answer: (C)

The subclavian site is often preferred for central venous access due to its lower risk for infection compared to other sites. The anatomical location of the subclavian vein allows for a direct approach with reduced exposure to potential contamination and a decreased risk of air embolism during the procedure. Additionally, the path from the subclavian vein to the superior vena cava is relatively short, which contributes to the efficiency of catheter placement and the speed at which infusions can occur. The vascular structure in this area also tends to be more stable and less prone to movement, making it less likely that the catheter will dislodge. Furthermore, the subclavian site is less subject to compression or obstruction that can occur with positioning, which is a concern with other sites, such as the femoral vein. While other sites like the jugular or femoral veins may offer ease of access or are commonly used, they carry higher risks for complications such as infection or thrombosis. The external access, while having minimal obstruction, may not provide the same advantages regarding infection risk and anatomical stability as the subclavian approach. Thus, the subclavian vein stands out as a preferred choice in many clinical settings.
