ARTERIES OF THIGH


FEMORAL ARTERY
FEMORAL ARTERY

? It is the main artery of the lower limb.

? It enters the femoral triangle behind the inguinal ligament

at the midinguinal point.

? It runs downward and medially successively via the femoral

triangle and adductor canal.

? At the lower end of the adductor canal , it leaves the thigh

via the adductor hiatus to go into the popliteal fossa where it

continues as the popliteal artery.


SURFACE MARKING

? Femoral artery is

represented by the

upper two-thirds of a

line joining the

midinguinal point to the

adductor tubercle.

The thigh is slightly

flexed, abducted and

laterally rotated
RELATIONS OF THE FEMORAL ARTERY IN THE

FEMORAL TRIANGLE

1. The main anterior relations are the skin, superficial fascia,

deep fascia and the anterior wall of the femoralsheath.

2. Posteriorly, the artery rests, from above downwards

on

? Psoas major,

? Pectineus ,

? The profunda artery comes behind the femoral artery as it

lies on the pectineus.

? The nerve to Pectineus passes (from the femoral nerve)

mediallybehind the artery.

? Adductor longus.

? The posterior wall of the femoral sheath Intervenes

between these structures and the artery.

RELATIONS OF THE FEMORAL ARTERY IN THE

FEMORAL TRIANGLE

3. The femoral artery & the femoral vein.

? The femoral artery is accompanied by the femoral vein Just

below the inguinal ligament. The vein is medial to the artery.

? However, the femoral vein gradually crosses to the lateral

side posterior to the artery.

? Femoral vein is directly behind the artery at the apex of the

femoral triangle, and lateral to the lower end of the artery.

RELATIONS OF THE FEMORAL ARTERY IN THE

FEMORAL TRIANGLE

4. The femoral nerve is lateral to upper part of the artery.

? Lower down the artery is related to the branches of the

nerve, some of which cross it.

? The branch to the pectineus crosses behind the upper part

of the artery.

? The medial cutaneous nerve of the thigh crosses the artery

from lateral to medial side near the apex of the femoral

triangle.

? The saphenous branch crosses the artery within the

adductor canal.

? The nerve to the vastus medialis is lateral to the artery in

the adductor canal.

THE FEMORAL TRIANGLE

5. The femoral branch of the genitofemoral nerve is also

lateral to the upper part of the femoral artery, within the

femoral sheath, but lower down it passes to the front of the

artery.

6. The profunda femoris artery a branch of the femoral

artery itself, and its companion vein, lie behind the upper part

of the femoral artery, where it lies on the pectineus.

? Lower down, however, the femoral and profunda

arteries are separated by the adductor longus
