What is the deep femoral artery?

The largest branch of the femoral artery and the principal arterial supply to the deep structures of the thigh.

In This Section

1. What is the deep femoral artery?

The largest branch of the femoral artery and the principal arterial supply to the deep structures of the thigh.

2. What is another anatomical name for the deep femoral artery?

The profunda femoris artery.

3. From which artery does the deep femoral artery originate?

The femoral artery.

4. Where does the deep femoral artery typically arise?

Approximately 3 to 5 cm inferior to the inguinal ligament.

5. From which aspect of the femoral artery does the deep femoral artery usually arise?

The posterolateral aspect, although its origin is variable.

6. What is the general course of the deep femoral artery?

It passes posteriorly and descends deep within the thigh toward the adductor muscles.

7. Which muscle lies anterior to the deep femoral artery in the proximal thigh?

The adductor longus muscle.

8. Between which muscles does the deep femoral artery descend in the thigh?

Between the adductor longus and adductor brevis proximally, then between the adductor longus and adductor magnus.

9. What are the principal branches of the deep femoral artery?

The medial circumflex femoral, lateral circumflex femoral, and perforating arteries.

10. Which branch of the deep femoral artery usually courses posteriorly around the proximal femur?

The medial circumflex femoral artery.

11. Which artery provides the principal blood supply to the femoral head in adults?

The medial circumflex femoral artery, primarily through its retinacular branches.

12. Which branch of the deep femoral artery passes laterally deep to the sartorius and rectus femoris muscles?

The lateral circumflex femoral artery.

13. What are the three commonly described branches of the lateral circumflex femoral artery?

The ascending, transverse, and descending branches.

14. Which branch of the lateral circumflex femoral artery contributes to the trochanteric anastomosis?

The ascending branch.

15. Which branch of the lateral circumflex femoral artery contributes to the cruciate anastomosis?

The transverse branch.

16. Which branch of the lateral circumflex femoral artery descends toward the lateral knee?

The descending branch, which may contribute to the genicular arterial network.

17. What are the perforating arteries of the deep femoral artery?

Muscular branches that penetrate the adductor magnus to reach the posterior compartment of the thigh.

18. How many perforating arteries are traditionally described as arising from the deep femoral artery?

Three named perforating branches, with the terminal continuation often described as a fourth perforating artery.

19. Which muscle is pierced by the perforating branches of the deep femoral artery?

The adductor magnus muscle.

20. Which thigh muscles receive substantial blood supply from the perforating arteries?

The hamstring muscles and portions of the adductor muscles.

21. What is the usual terminal continuation of the deep femoral artery?

The terminal perforating artery in the distal thigh.

22. What is the cruciate anastomosis of the thigh?

An arterial network connecting circumflex femoral, inferior gluteal, and perforating arterial branches near the proximal posterior thigh.

23. What is the trochanteric anastomosis?

An arterial network near the greater trochanter formed by circumflex femoral and gluteal arterial branches.

24. Why is the deep femoral artery important for collateral circulation?

Its branches form arterial connections that may help maintain lower limb perfusion when the femoral artery is obstructed.

25. What anatomical variation commonly affects the circumflex femoral arteries?

Either circumflex artery may arise directly from the femoral artery rather than the deep femoral artery.

26. Why is the deep femoral artery clinically important in proximal femoral fractures?

Injury to its circumflex branches can compromise femoral head perfusion or cause significant bleeding.

27. What is a potential complication of injury to the deep femoral artery during orthopedic procedures?

Hemorrhage or pseudoaneurysm formation within the thigh.
