The deep venous system of the lower limb.

In This Section

1. Is the femoral vein part of the superficial or deep venous system?

The deep venous system of the lower limb.

2. Which vein continues proximally as the femoral vein?

The popliteal vein.

3. At which anatomical opening does the popliteal vein become the femoral vein?

The adductor hiatus of adductor magnus.

4. What is the general course of the femoral vein through the thigh?

It ascends from the adductor hiatus through the adductor canal and femoral triangle.

5. Which artery accompanies the femoral vein through the thigh?

The femoral artery.

6. What is the relationship of the femoral vein to the femoral artery immediately below the inguinal ligament?

The femoral vein lies medial to the femoral artery.

7. How does the femoral vein's position relative to the femoral artery change distally?

It passes posterior to the artery and becomes more lateral toward the adductor hiatus.

8. Which anatomical space contains the proximal femoral vein?

The femoral triangle.

9. Which fibrous compartment encloses the proximal femoral vein beneath the inguinal ligament?

The femoral sheath.

10. Which compartment of the femoral sheath contains the femoral vein?

The intermediate compartment.

11. Which structure lies immediately medial to the femoral vein within the femoral sheath?

The femoral canal.

12. Does the femoral nerve lie inside the femoral sheath?

No, it lies lateral to the femoral artery and outside the sheath.

13. Which musculoaponeurotic passage contains the femoral vein in the middle thigh?

The adductor canal, also called Hunter's canal.

14. What does the femoral vein become after passing proximally beneath the inguinal ligament?

The external iliac vein.

15. Which major superficial vein drains into the femoral vein near the groin?

The great saphenous vein.

16. What is the saphenofemoral junction?

The junction where the great saphenous vein enters the femoral vein.

17. Through which opening does the great saphenous vein pass before joining the femoral vein?

The saphenous opening in the fascia lata.

18. Which major deep thigh vein drains into the femoral vein?

The profunda femoris vein, also called the deep vein of the thigh.

19. Which circumflex femoral veins may drain directly or indirectly into the femoral vein?

The medial and lateral circumflex femoral veins.

20. Which superficial tributaries commonly enter the femoral vein near the saphenofemoral junction?

The superficial epigastric, superficial circumflex iliac, and external pudendal veins, often via the great saphenous vein.

21. What is the primary function of the femoral vein?

To return venous blood from the lower limb toward the pelvis and heart.

22. What structures within the femoral vein help prevent backward blood flow?

Venous valves.

23. How do contractions of thigh muscles assist venous return through the femoral vein?

They compress deep veins, promoting proximal blood flow with the assistance of venous valves.

24. Why is the term superficial femoral vein anatomically misleading?

The femoral vein is a deep vein, so thrombosis within it is classified as deep vein thrombosis.

25. What is femoral deep vein thrombosis?

Formation of a blood clot within the femoral vein.

26. What serious complication can occur if a thrombus detaches from the femoral vein?

Pulmonary embolism.

27. Which imaging technique is commonly used to evaluate femoral vein thrombosis?

Compression duplex ultrasonography.

28. What ultrasound finding is characteristic of a femoral vein containing thrombus?

Failure of the vein to collapse completely under transducer compression.

29. Why is the common femoral vein frequently used for central venous access?

It is a relatively large, accessible vein with predictable landmarks beneath the inguinal ligament.

30. Which anatomical landmark helps distinguish the common femoral vein from the femoral artery during ultrasound-guided access?

The vein usually lies medial to the artery and is more compressible.
