femoral vein
femoral nerve

53
Q

Femoral sheath

A

funnel shaped fascial tube which surrounds proximal part of femoral vessels - NOT nerve
creates femoral canal medial to them which contains lymphatics

NAVEL

56
Q

What is the adductor canal?

A

femoral triangle structures leave distally an burrow beneath muscles to create canal

57
Q

How does canal reach popliteal fossa?

John Hunter

ligate femoral artery in adductor canal to treat popliteal artery aneurysms
