Which of the following is a typical access site for interventional radiology?

In interventional radiology, the femoral artery and vein are among the most commonly utilized access sites for a variety of procedures. This is largely due to their large diameter, which allows for easy catheterization and manipulation of devices needed for diagnostic or therapeutic interventions. Additionally, the femoral area provides a straightforward anatomical landmark, simplifying the process for practitioners.

Accessing the femoral artery or vein facilitates numerous interventions, such as angiograms, stent placements, and many other vascular procedures, because it allows for good access to the ascending aorta and the entire vascular tree. This location also tends to yield fewer complications compared to more peripheral access points and is a well-established route used by interventional radiologists.

In contrast, while the subclavian vein can also be used as an access point, it is less common than the femoral vein due to risks associated with potential complications such as pneumothorax. The radial nerve is not traditionally used for vascular access in interventional procedures, as it is primarily a nerve structure and not a vascular access site. The posterior tibial vein, while a legitimate vascular structure, is not as frequently used for several common interventional radiology procedures, especially when more accessible and larger vessels like the femoral artery and
