Flashcards in Veins of lower limb Deck (22):

Origin of anterior tibial vein

Formed by some veins from dorsal venous arch


Origin of posterior tibial vein and fibular vein

Medial and lateral plantar veins (from plantar aspect of foot)


Course of posterior tibial vein

Accompanies posterior tibial artery
Enters leg posterior to medial malleolus


Origin of popliteal vein

Forms on posterior surface of knee Combination of:
Anterior tibial vein
Posterior tibial vein
Fibular vein


Termination of popliteal vein

Popliteal vein enters thigh via adductor canal and continues as the femoral vein


Course of femoral vein

Situated anteriorly and accompanies femoral artery


Termination of femoral vein

Leaves thigh by passing under inguinal ligament
Continues as external iliac vein


Course of deep vein of thigh/ profundus femoris vein

Deep vein of thigh drains blood from thigh muscles via perforating veins
Empties into distal section of femoral vein


Course of superior and inferior gluteal veins

Drain blood from gluteal region
Empty into internal iliac vein


Where are superficial veins located

Subcutaneous tissue


What are the main superficial veins

Great sephanous vein
Small sephanous vein


Origin of great sephanous vein

Formed by dorsal venous arch of foot and medial marginal vein of foot


Course of great sephanous vein

Ascends up medial side of leg
Passes anteriorly over medial malleolus
Passes superficial to medial epicondyle of femur, hands breadth posterior to medial border of patella
Received tributaries from small superficial veins during ascent


Termination of great sephanous vein

Drains into femoral vein at sephanous opening immediately inferior to inguinal ligament


What procedure can great sephanous vein be used for

Coronary artery bypass


Origin of small sephanous vein

Lateral marginal vein of foot and dorsal venous arch of foot


Course of small sephanous vein

Ascends up posterior side of leg
Passes posteriorly over lateral malleolus along lateral border of calcaneal tendon
Moves between 2 heads of gastrocnemius muscle
Empties into popliteal vein within popliteal fossa


What is varicose veins

Venous valves in legs become incompetent so blood flows from deep veins into superficial veins
This increases intraluminal pressure causing veins to be dilated and torturous


Consequences of chronic varicose veins

Increased venous pressure damages cells causing blood to extrude into skin
This results in:
Brown pigmentation of surrounding tissue
Ulceration of surrounding tissue


Treatment of varicose veins

Surgical movement of sephanous systems
Valve reconstruction
Tying off affected valves


Where are deep veins located

Underneath deep fascia
Usually in same vascular sheath as major arteries


What is Saphenous cutdown

Venipuncture or cannulation of great Saphenous vein if you can't find another vein
