great saphenous and small saphenous

Question 1

describe great saphenous vein

Answer 1

• longest vein
  -graph at: front of medial maleolus

Question 2

formation and termination of great saphenous vein

Answer 2

F:medial end of dorsal venous arch with medial marginal vein
T: Femoral vein aft piercing cribiform

Question 3

tributaries of great saphenous vein?

Answer 3

start:medial marginal vein
just below knee: ant. vein of leg
post. arch vein
vein from calf
in the thigh: accessory saphenous vein
ant cutaneous vein of thigh
b4 piercing cribiform fascia: superficial epigastric vein
superficial circumflex iliac v
superficial external pudendal vein

just b4 termination: deep ext pudendal vein

Question 4

clinical aspect of GSV

Answer 4

varicose vein

cause: increased intraabdorminal pressure
incompetency of valves( sapheno-femoral valve,valves of perforating veins(5)
how:
faulty valves in deep perforating veins-> blood from deep drain into superficial vein-> increased bp-> varicose veins

faulty valves-> reversed blood flow-increased pressure-> varicose vein

Question 5

formation and termination of small saphenous vein

Answer 5

F:by union of the lateral end of the dorsal venous arch with lateral marginal vein
T: at back of popliteal fossa where it terminates into popliteal vein

Question 6

course of small sv

Answer 6

• found in the superficial fascia
• runs behind lat maleolus
  -along lat marginal of achilles tendon
• run up along with sural nerve between gastrocnemius heads
• connects to deep vein via lateral ankle perforator
