Corpus: Deep femoral artery
Synonyms: Arteria profunda femoris
1. Definition
The deep femoral artery is a branch of the femoral artery that runs deeper in the tissue of the thigh than its parent vessel.
2. Course
The deep femoral artery leaves the femoral artery about 3 to 6 cm distal to the inguinal ligament. It runs caudally near the femur between the pectineus muscle and the adductor longus muscle.
3. Branches
- Medial circumflex femoral artery: runs dorsally between the iliopsoas and pectineus muscles and follows the edge of the external obturator muscle to the trochanteric fossa, where it anastomoses with the lateral circumflex femoral artery.
- Ascending branch: branches out on the anterior surface of the adductors
- Deep branch: reaches the quadratus femoris muscle, the joint capsule, the adductor magnus muscle and the flexors
- Acetabular branch: runs through the incisura acetabuli to the hip joint
- Lateral circumflex femoral artery: runs laterally between the rectus femoris muscle and the upper parts of the vastus muscles
- Ascending branch: penetrates under the tensor fasciae latae muscle to the gluteal muscles and the hip joint capsule; anastomoses with the medial circumflex femoral artery and the gluteal arteries
- Transverse branch: runs laterally
- Descending branch: branches under the rectus femoris muscle into the extensor muscles up to the knee joint
- Perforating arteries: usually three branches that pierce the base of the adductor muscles dorsally
- Primary perforating artery: runs dorsally from the lower edge of the pectineus muscle through the insertions of the adductor brevis and magnus muscles and gives off a nutritional femoral artery for the proximal femur bone
- Secondary perforating artery: runs through the insertion of the adductor brevis and magnus muscles
- Tertiary perforating artery: terminal branch of the deep femoral artery; breaks through the adductor magnus muscle approx. 3 cm above the adductor hiatus and gives off a nutritional femoral artery for the distal femur.
The two circumflex femoral arteries also arise directly from the femoral artery in 20 % of cases.
4. Supply area
The deep femoral artery supplies the hip joint and the entire thigh musculature, the remaining femoral artery has no supply function up to the transition into the popliteal artery.
