Circumflex femoral artery

Circumflex femoral arteries.

The Circumflex Femoral Artery is a significant blood vessel in the human body, specifically located in the upper leg. It is divided into two branches: the lateral and medial circumflex femoral arteries.

Anatomy

The circumflex femoral artery arises from the femoral artery, which is the main artery providing blood to the lower limb. The lateral circumflex femoral artery typically branches off the femoral artery deep to the sartorius and rectus femoris muscles, while the medial circumflex femoral artery usually branches off the femoral artery near the hip joint.

Function

The primary function of the circumflex femoral artery is to supply blood to the thigh and hip muscles. The lateral branch primarily supplies the vastus lateralis, rectus femoris, and the hip joint, while the medial branch supplies the head and neck of the femur, the hip joint, and the adductor muscles.

Clinical Significance

Damage to the circumflex femoral artery can lead to significant blood loss due to its large size and the amount of blood it carries. It can also lead to compartment syndrome, a serious condition that involves increased pressure in a muscle compartment. It can lead to muscle and nerve damage and problems with blood flow.
