What is an alternative site for access in interventional radiology?

The axillary artery and vein serve as alternative access sites in interventional radiology due to their anatomical location and vascular accessibility. They are particularly useful for various interventional procedures, especially when traditional access points, such as the femoral or radial arteries, may not be ideal due to patient-specific factors like previous surgery, vascular anomalies, or complications. The axillary region allows for easier manipulation and can be beneficial in certain types of interventions, including those related to the upper extremities or thoracic area, where deeper structures require access. Additionally, using the axillary artery can provide a larger lumen compared to smaller peripheral vessels, facilitating the passage of larger catheters and devices necessary for a variety of interventional procedures.

This access point is also associated with a lower risk of complications in specific patient populations, making it a valuable option in the interventional radiologist's toolkit.
