VENOUS DRAINAGE OF LOWER LIMB

VENOUS DRAINAGE OF LOWER LIMB

VEINS OF LOWER LIMB:

1. Superficial Veins:

• Greater Saphenous- Largest vein of the body

• Small Saphenous

2. Deep Veins:

• Femoral vein 

• Profunda femoris vein

• Popliteal vein

• Peroneal vein

• Anterior & Posterior tibial vein

3. Perforating Veins:

• Provided with valves which direct blood from superficial to deep veins

• Two types of perforating veins: Direct & Indirect.

VEINS	RECIEVES BLOOD FROM	DRAINAGE	ACCOMPANIES
Anterior Tibial	Anterior compartment of leg	Popliteal vein	Ant. tibial artery
Posterior Tibial	Posterior compartment of leg and plantar surface of the foot	Popliteal vein	Post. tibial artery
Peroneal/Fibular	Lateral compartment of the leg	Posterior tibial veins	Fibular arteries
Popliteal	Peroneal vein before reaching the knee joint(blood from the knee joint and muscles in the thigh and calf)	Femoral vein when leaving the adductor canal	Popliteal artery(extends from the femoral artery behind the popliteal fossa which is the space behind the knee)
Profunda femoris	Inner thigh	Join with the femoral vein at ischial tuberosity	Profunda femoris artery
Femoral(bounds femoral ring from one side)( contains valve)	Popliteal vein Profundafemoris vein Great saphenous vein	Lies in adductor or hunter’s canal External iliac vein(at inf. margin of inguinal ligament)	Femoral artery(in the femoral sheath)
Great Saphenous (passing anterior to the medial malleolus visualized and palpated)	Dorsal vein of the first digit (the large toe)(start as continuation of medial marginal vein)	Dorsal venous arch of the foot Femoral vein in the region of the femoral triangle at the saphenofemoral junction.	–
Small Saphenous Vein (large vein of the superficial posterior leg)( tributary of lateral marginal vein)	Originates where Dorsal vein from the fifth digit (smallest toe) merges with the lateral side of dorsal venous arch of the foot	Popliteal vein,( approximately at or above the level of the knee joint)(runs behind lateral malleolus)	Sural nerve Achillis tendon  medial to vein

Note : The most important perforator of the Lower limb is between Long saphenous and femoral vein
