In This Section

1. Where are the superficial veins of the lower limb located?

Within the subcutaneous tissue, superficial to the deep fascia.

2. What are the two principal superficial veins of the lower limb?

The great saphenous vein and small saphenous vein.

3. Which venous network on the dorsum of the foot contributes to the superficial venous drainage?

The dorsal venous network, including the dorsal venous arch.

4. Which superficial vein arises from the medial end of the dorsal venous arch?

The great saphenous vein, through the medial marginal vein.

5. Which superficial vein arises from the lateral end of the dorsal venous arch?

The small saphenous vein, through the lateral marginal vein.

6. What is the longest superficial vein in the human body?

The great saphenous vein.

7. What is the relationship of the great saphenous vein to the medial malleolus?

It passes anterior to the medial malleolus.

8. Which nerve accompanies the great saphenous vein along the medial leg?

The saphenous nerve.

9. What is the course of the great saphenous vein through the lower limb?

It ascends along the medial leg and thigh toward the groin.

10. Which deep vein receives the great saphenous vein?

The common femoral vein.

11. What is the saphenofemoral junction?

The junction between the great saphenous vein and common femoral vein.

12. Through which opening does the great saphenous vein pass before entering the common femoral vein?

The saphenous opening in the fascia lata.

13. Which fascial covering overlies the saphenous opening?

The cribriform fascia.

14. Which superficial tributaries commonly join the great saphenous vein near the groin?

The superficial epigastric, superficial circumflex iliac, and superficial external pudendal veins.

15. What is the anterior accessory great saphenous vein?

A superficial venous trunk running anterior to the great saphenous vein in the thigh.

16. What is the relationship of the small saphenous vein to the lateral malleolus?

It passes posterior to the lateral malleolus.

17. What is the usual course of the small saphenous vein through the leg?

It ascends along the posterior calf toward the popliteal fossa.

18. Which sensory nerve commonly accompanies the small saphenous vein in the posterior calf?

The sural nerve.

19. Which deep vein usually receives the small saphenous vein?

The popliteal vein.

20. What is the saphenopopliteal junction?

The junction where the small saphenous vein enters the popliteal vein.

21. What anatomical variation commonly affects the termination of the small saphenous vein?

It may continue into the thigh or drain into other superficial or deep veins.

22. What is the vein of Giacomini?

An intersaphenous vein that connects the small saphenous system with the great saphenous system in the thigh.

23. Which vessels connect the superficial and deep venous systems across the deep fascia?

Perforating veins.

24. What is the normal direction of blood flow through competent perforating veins?

From superficial veins toward deep veins.

25. What structures prevent sustained backward flow in most superficial veins?

Venous valves.

26. How do superficial veins contribute to body temperature regulation?

They adjust blood flow near the skin to facilitate or reduce heat loss.

27. What are varicose veins?

Abnormally dilated, elongated, and tortuous superficial veins, commonly associated with venous reflux.

28. How does superficial venous valve incompetence contribute to chronic venous insufficiency?

It permits venous reflux, increasing ambulatory venous pressure in affected vessels.

29. What is superficial venous thrombosis?

Thrombus formation within a superficial vein, often accompanied by local inflammation.

30. Which imaging technique is commonly used to assess superficial venous reflux and thrombosis?

Duplex ultrasonography.
