GREAT SAPHENOUS VEIN

SUMMARY

1. Longest vein in the body. 2. Continuation of the medial marginal vein of the foot.

3. Courses in front of the medial malleolus => crosses the medial surface of the tibia obliquely towards the knee => where it lies a hands-breath behind the medial border of the patella.

4. It spirals forwards around the medial convexity of the thigh and ends by passing through the cribriform fascia covering the saphenous opening (3.5cm below and lateral to the pubic tubercle). 

5. Here it joins the femoral vein along with 4 others (superficial circumflex iliac, superficial epigastric, superficial and deep external peudendal veins). 

6. It may also be joined by the anterolateral and posteromedial femoral veins here.
