Which artery is primarily accessed for lower extremity interventions?

The femoral artery is primarily accessed for lower extremity interventions because it is the major artery supplying blood to the lower limb. This artery is easily accessible due to its superficial location in the groin area, allowing for effective catheterization and intervention in various procedures, such as angioplasty, stenting, and endovenous laser treatment for varicose veins.

Additionally, accessing the femoral artery provides a direct pathway to the arterial system of the legs, facilitating the treatment of conditions like peripheral artery disease. Its size and reliability make it the most commonly used access point for a range of interventional radiology procedures targeting the lower extremities. The other arteries listed are less relevant for interventions focused on the lower limbs, as they either supply different regions or are more challenging to access safely.
