This is all about lower limbs

2.  Ext Iliac  Common Fem
▪ Crosses under Inguinal Ligament
 BRANCHES
▪ Superficial Circumflex Femoral a.
▪ Superficial Inferior Epigastric a.
▪ Superficial Pudendal a.
 Profunda Femoris a. (biggest branch)
 Common Femoral  Superficial Femoral
a.

3. External Iliac Artery
Common Femoral Artery
Inguinal Ligament
Profunda Femoris Artery
Superficial Femoral Artery

4.  Biggest Branch of Common Femoral a.
 5cm distal to Ing. Ligament
 6 BRANCHES
▪ 2 Circumflex Femoral
• Medial
• Lateral
▪ 4 Perforating Arteries (4)

5.  Form ring around upper Femur
 Lateral Circumflex has 2 branches
▪ Ascending branch than anastomoses with superior gluteal a.
▪ Descending branch to the knee

6.  Supply muscles of thigh
 Surround Femur
 Last is continuation of Profunda a.

7. Lateral Circumflex
Perforating arteries
Profunda Femoris

8.  Passes in Adductor Canal
▪ Between Vastus Med / Adductors / Sartorius
 Through Adductor Hiatus
▪ At junction of upper 2/3 and lower 1/3 of femur
▪ Into Popliteal Fossa  Popliteal Artery
 Just before this – descending branch to
genicular anastomosis

9. Adductor Brevis
Adductor Magnus
Superficial Femoral
Sartorius
Vastus Medialis
Popliteal Artery
Lateral Superior Genicular Artery

10.  Branches to Genicular Anastomosis
and Knee Joint
 Divides at lower border of Knee
Joint
▪ Posterior Tibial artery (which gives off Peroneal a.)
▪ Anterior Tibial artery

11. Popliteal Artery
Inferior Lateral Genicular Artery
AnteriorTibial Artery
PosteriorTibial Artery
Peroneal Artery
TibioperonealTrunk

12.  Larger of the two
 2.5cm from its origin  Peroneal a.
 Then descends and becomes more
medial
 At the ankle
▪ Medial malleolar branch
 Then passes posterior to medial
malleolus
▪ Halfway between tip of malleolus and midline
▪ Branches  medial and lateral plantar aa
(the principal supply of the foot)

13. Posterior Tibial Artery
Medial Malleolus

14.  Descends to lie posteromedially of the
fibula
 Runs behind tibiofibular joint
 Ends as Calcaneal Branch

15. Peroneal Artery
Calcaneal Branch of Peroneal artery

16.  Passes above upper margin of
interosseus membrane
 Descends anterior to membrane
 Becomes superficial at ankle midway
between malleoli
 Continues as Dorsalis Pedis Artery
▪ Passes between 1st and 2nd metatarsals to join
plantar arch

17. Anterior
Tibial
Artery
POSTERIOR KNEE ANTERIOR KNEE

18. Dorsalis Pedis Artery
Anterior Tibial Artery
