What is the function of the common femoral vein?

The common femoral vein plays a crucial role in the venous return system of the body, particularly in the lower extremities. Its primary function is to carry deoxygenated blood from the lower part of the leg, including the thigh, back to the heart. This vein is formed by the confluence of the popliteal vein and the superficial femoral vein, allowing it to collect blood from various structures in the leg before it drains into the external iliac vein.

Understanding the anatomy and function of the common femoral vein is essential, especially for interventional radiologists who may be involved in procedures relating to venous access or treatment of venous conditions. Recognizing that the common femoral vein is specifically associated with the lower limbs underscores its role in facilitating efficient circulation and maintaining venous return against gravity, which is critical for overall cardiovascular health.
