ANATOMY

Detailed explanation-1: -The femoral artery travels in the lateral compartment of the femoral sheath . It is a continuation of the external iliac artery, commencing as it passes under the inguinal ligament. [9] Distally, the femoral artery passes into the adductor canal, becoming the popliteal artery as it passes through the adductor hiatus.

Detailed explanation-2: -The external iliac artery is the major artery responsible for blood supply to the lower extremities. At the level of the inguinal ligament, the external iliac artery becomes the common femoral artery.

Detailed explanation-3: -The femoral artery is the direct continuation of the iliac artery and enters the thigh after passing below the inguinal ligament. Arterial puncture must always occur distal to the ligament to prevent uncontrolled hemorrhage into the pelvis or peritoneum.

Detailed explanation-4: -The common femoral artery forms as a continuation of the external iliac artery below the level of the inguinal ligament. It is found just medial to the midpoint of the inguinal ligament in the inguinal crease region.

Detailed explanation-5: -The femoral artery runs to the lower thigh and ends behind the knee. At the knee, the femoral artery becomes the popliteal artery.
