Femoral Artery
Continuation of the external iliac A
Enters behind inguinal lig. @midinguinalpoint
Descends through femoral triangle (1” in
sheath)
Courses beneath sartorius to enter the
adductor canal
Changes to popliteal A as it passes through
adductor hiatus

ProfundafemorisA
Arises laterally from the femoral A, 1’’ below
the
inguinal lig.
Spirals posterior to femoral A & V to reach the

Passes between pectineus & adductor longus

Lateral circumflex femoral A
Arises from the lateral side of profundaA
Passes between the branches of the
f
emoral N, dividing them into superficial
and deep groups
Disappears from t
he femoral triangle
beneath sartoriusto lie deep to rectus
femoris.
Here it breaks up into 3 branches
Ascending br. Gives a
branch to the
trochanteric anastomosis and passes on
towards the ASIS
Transverse br. f
orm one limb of the
cruciate anastomosis
Descending br. s
lopes steeply downwards,
with the nerve to vastus lateralisends by
anastomosing at Patellar AnastomosisDr Rajiv Ranjan
Medial circumflex femoral A
Arises from the medial side of the profundaA
Passes backwards between pectineus & psoas
tendon.
Running above the upper border of Adductor
brevis, it passes between the contiguous
borders of quadratus femoris and adductor
magnusto enter the gluteal region.
