, Arteries of Lower Limb

FEMORAL ARTERY
- Chief artery of L.L
- Continuation of external iliac artery as the vessel passes under the inguinal
ligament
Surface marking

Thigh-slightly flexed, abducted & laterally rotated

Upper 2/3rd of the line joining midinguinal point to adductor
tubercle

Course

 Enters the thigh behind inguinal ligament at midinguinal point (Pubic symphysis & ASIS)
 Just below the inguinal ligament artery is lateral to vein
 Lies in lateral compartment of the femoral sheath
 Passes downwards & medially
-femoral triangle
-adductor canal (deep to Sartorius)
 Vein gradually crosses medial to lateral deep to artery
 Saphenous nerve crosses to medial superficially
 through adductor hiatus (at junction of upper 2/3rd & lower 1/3rd of thigh)
 continues as popliteal artery




Branches
In femoral triangle – 4 superficial –
