, Venous Drainage of Lower Limb
 Veins of lower limb are more muscular than any other veins

3 types deep
veins Superficial Veins
Perforating veins


Deep veins

 Ant. Tibial
 Post. Tibial
 Peroneal
 Popliteal
 Femoral
 Valves-more numerous
 Supported by surrounding
powerful muscles
 Accompany major arteries
 More efficient
 Most of the venous return
happens through the deep
vein system.

Superficial veins
 Great (long) saphenous vein
 Small (short) saphenous vein
- Drains into deep veins via
perforating veins
 Less valves

Great Saphenous vein
Longest vein in the body.
Course

 Starts by union of medial marginal vein & the medial end of dorsal
venous arch
 Runs upwards in front of medial malleolus (constant position)
 Crosses the lower third of the medial surface of the tibia obliquely along
with the saphenous nerve (In varicose surgery sensory loss in medial
side of leg)
 Along medial side of leg
 To Posteromedial aspect of knee (hand’s breadth behind the medial border
of the patella)
 Spirals forwards around the medial convexity of the thigh
