Common femoral artery

The common femoral artery (CFA) is the continuation of the external iliac artery (EIA) at the level of the inguinal ligament. As well as supplying oxygenated blood to the leg, it gives off smaller branches to the anterior abdominal wall and superficial pelvis. The artery lies medial to the midpoint of the inguinal ligament, halfway between the anterior superior iliac spine and pubic tubercle. The femoral vein lies medially and both emerge, from under the inguinal ligament, within the femoral sheath to then caudally traverse the femoral triangle. Lateral but outside the sheath is the femoral nerve. The common femoral artery terminates within the femoral triangle by bifurcating into its terminal branches: the superficial femoral artery and the profunda femoris artery. The superficial femoral artery ends as it passes through the adductor hiatus in adductor magnus to become the popliteal artery.
