Which access point is NOT typically used for IV filter placement?

The placement of an inferior vena cava (IVC) filter is typically performed through specific venous access points that facilitate the safe and effective deployment of the filter. The femoral vein and internal jugular vein are commonly utilized for this procedure due to their accessibility and the large caliber of the vessels, which allows for the introduction of the specialized catheter and filter delivery systems.

The brachial vein, however, is not typically used for IVC filter placement. While it is a viable venous access site for certain procedures, it does not provide the optimal pathway to the inferior vena cava or the necessary anatomical positioning for successful filter deployment. The brachial vein is smaller and more difficult to navigate for such procedures, making it less favorable compared to the other access points mentioned.

The femoral artery is also not an appropriate choice for IVC filter placement, as it is primarily an arterial access point, and the IVC filter is intended to be deployed in the venous system. In summary, the brachial vein is not routinely used for IVC filter placement because it lacks the ideal characteristics that the other access points offer, such as adequate size, anatomical location, and ease of access to the inferior vena cava.
