Significance of PROFUNDA FEMORIS ARTERY in Deep branches in BRANCHES of Femoral Artery in Arteries of the Lower Limb
- The largest branch of femoral artery
2. The main blood supply of the thigh
BEGINNING of PROFUNDA FEMORIS ARTERY in Deep branches in BRANCHES of Femoral Artery in Arteries of the Lower Limb
Arises from the femoral artery 4 cm. below the inguinal ligament.
COURSE of PROFUNDA FEMORIS ARTERY in Deep branches in BRANCHES of Femoral Artery in Arteries of the Lower Limb
- It leaves the femoral triangle by passing deep to adductor longus.
- lt descends on adductor brevis then adductor magnus.
TERMINATION of PROFUNDA FEMORIS ARTERY in Deep branches in BRANCHES of Femoral Artery in Arteries of the Lower Limb
It ends by becoming the 4th perforating artery
BRANCHES of PROFUNDA FEMORIS ARTERY in Deep branches in BRANCHES of Femoral Artery in Arteries of the Lower Limb
- Medial circumflex femoral artery
- Lateral circumflex femoral artery
- 4 perforating branches
Alternative name for PROFUNDA FEMORIS ARTERY in Deep branches in BRANCHES of Femoral Artery in Arteries of the Lower Limb
Deep femoral artery
Definition of Superficial femoral artery
The Part of femoral artery below the profunda.
Definition of Common femoral artery
The Part of femoral artery above the profunda.
SURFACE ANATOMY of Femoral Artery in Arteries of the Lower Limb
It is represented by the upper 2/3 of a line connecting the following 2 points:
- Mid-inguinal point
- Adductor tubercle
Site of Mid-inguinal point in SURFACE ANATOMY of Femoral Artery in Arteries of the Lower Limb
Midway between A.S.I.S & symphysis pubis
Site of mid point of inguinal ligament
Midway between A.S.I.S and pubic tubercle
Site of Adductor tubercle in SURFACE ANATOMY of Femoral Artery in Arteries of the Lower Limb
At the lower end of the tendon of adductor Magnus muscle
SURGICAL IMPORTANCE of Femoral Artery in Arteries of the Lower Limb
After ligature of femoral artery in the subsartorial canal, the collateral circulation is established through the anastomosis between:
- Descending branch of lateral circumflex femoral artery and descending genicular branch of femoral artery
- 4th. perforating branch of profunda & the muscular branches of the popliteal artery
Descending branch of lateral circumflex femoral artery in SURGICAL IMPORTANCE of Femoral Artery in Arteries of the Lower Limb
branch of profunda Femoris artery

- SURGICAL IMPORTANCE
BEGINNING of Popliteal Artery in Arteries of the Lower Limb
As a continuation of femoral artery at the adductor hiatus.
COURSE of Popliteal Artery in Arteries of the Lower Limb
It descends as the deepest structure in the popliteal fossa lying on :
- Popliteal surface of femur
- Back of capsule of knee joint.
- Fascia covering popliteus muscle.
TERMINATION of Popliteal Artery in Arteries of the Lower Limb
At the lower border of popliteus muscle by dividing into 2 terminal branches :
- Anterior tibial artery.
- Posterior tibial artery
Alternative name for Posterior tibial artery in TERMINATION of Popliteal Artery in Arteries of the Lower Limb
Tibio-peroneal trunk
BRANCHES of Popliteal Artery in Arteries of the Lower Limb
a. Muscular branches
b. Genicular branches
Genicular branches in BRANCHES of Popliteal Artery in Arteries of the Lower Limb
- Superior & inferior medial genicular artery
- Superior & inferior lateral genicular artery
- Middle genicular artery
SURGICAL IMPORTANCE of Popliteal Artery in Arteries of the Lower Limb
Popliteal artery is a common site of aneurysm
The reason why Popliteal artery is a common site of aneurysm in SURGICAL IMPORTANCE of Popliteal Artery in Arteries of the Lower Limb
because of :
- A factor responsible for arterial wall changes
- A factor responsible for continuous traction
A factor responsible for arterial wall changes in The reason why Popliteal artery is a common site of aneurysm in SURGICAL IMPORTANCE of Popliteal Artery in Arteries of the Lower Limb
The constant pulsations of the artery against the underlying tendon of adductor Magnus
A factor responsible for continuous traction in The reason why Popliteal artery is a common site of aneurysm in SURGICAL IMPORTANCE of Popliteal Artery in Arteries of the Lower Limb
It’s fixed to the capsule of knee joint by a fibrous band just above the femoral condyles.
