Which veins are used for non-tunneled CVAD selection?

The internal and external jugular veins are commonly used for non-tunneled central venous access devices (CVAD) selection. These veins are located in the neck and provide direct access to the central venous system, which is essential for the administration of medications, fluids, or blood products, as well as for monitoring central venous pressure. Their anatomical position allows for relatively easy access, making them ideal candidates for non-tunneled CVAD insertion, especially in emergency settings or situations requiring immediate vascular access.

The internal jugular vein is particularly favorable due to its large size and straight course towards the heart, facilitating catheter placement. The external jugular vein can also be utilized, although it is less commonly chosen due to its smaller diameter and more superficial position, making it less ideal for long-term access compared to the internal jugular.

The other options involve veins that are either less commonly used for non-tunneled access or are not optimal for such procedures. For instance, the saphenous and femoral veins, while accessible, are typically not preferred for central access due to higher risks of infection and complications associated with femoral vein punctures. The basilic and brachial veins are located in the arm and are generally not used for
