Which veins are most commonly used for CVAD insertion?

Which veins are most commonly used for CVAD insertion?

• A. Radial vein, cephalic vein, and basilic vein
• B. Internal jugular vein, subclavian vein, and femoral vein
• C. Brachial vein, saphenous vein, and external jugular vein
• D. Popliteal vein, dorsal venous arch, and median cubital vein

Answer: (B)

The most commonly used veins for Central Venous Access Device (CVAD) insertion are the internal jugular vein, subclavian vein, and femoral vein. These venous access sites are preferred due to their anatomical location, which allows for easy access to the central venous system. The internal jugular vein is accessible and has a relatively large diameter, which accommodates the insertion of larger catheters necessary for various therapies, including chemotherapy and total parenteral nutrition. Its close proximity to the heart and the ability to visualize it with ultrasound further enhance its desirability as an insertion site. The subclavian vein is also a popular choice due to its length and larger caliber, which allows for a stable and long-term catheter placement. It has a lower risk of infection compared to some other sites and is less likely to interfere with mobility. The femoral vein, although not ideal for long-term access due to a higher infection rate, is still commonly used, especially in emergency situations or when other sites are not accessible. Its deep location and the prevalence of anatomical landmarks make it a viable option when central access is urgently needed. Overall, these three veins are selected because they effectively support the clinical requirements for CVAD applications while balancing ease of access,
