42
Q

Origin of arteries supplying hip

A

External iliac -> profunda femoris -> medial, lateral circumflex femoral arteries, ascending 1st perforator

Internal iliac -> gluteal arteries

Obturator artery → head of femur (ligamentum teres artery)

A
46
Q

Course of long saphenous vein

A

Starts at the confluence of dorsal vein of big toe and dorsal venous arch

Goes anterior to medial malleolus and goes posterior to tibia in the popliteal fossa

Goes up the medial aspect of the thigh until it pierces the fascia lata to enter femorasaphenous junction (2cm lateral and inferior to pubic tubercle)

47
Q

Tributaries to great saphenous vein

A

Variable position but some say:

1cm below and above medial malleolus

10 cm above medial malleolus

Half way up the calf

Just below knee

48
Q

Which nerve close to great saphenous vein? what is its significance?

A

Saphenous nerve (branch of femoral nerve)

Could be damaged in lower leg great saphenous vein stripping
