Anastomosis in Lower Limb

Rasha M Elshinety, PhD, MDLecturer of Anatomy & Emryology

1 -Anastomosis between superior and inferior gluteal arteries

Arterial Anastomosis of the Lower Limb

• They serve as collateral circulation between arteries of lower limb and above

2- Anastomosis around ASIS

It composed of:1. Superficial circumflex iliac artery 2. Deep circumflex iliac artery3. Lateral circumflex femoral artery4. Superior gluteal artery

3 -Trochanteric Anastomosis:

• Is present in the trochanteric fossa of the femur and is composed of:

1. Inferior branch of superior gluteal artery.2. Inferior gluteal artery.3. Ascending branch of medial circumflex

femoral artery.It gives the main supply for the head of femur

4- Cruciate Anastomosis

• It lies at the level of the middle of lesser trochanter (upper part of adductor magnus)

• It is composed of:1. Ascending branch of first perforator2. Descending branch of inferior gluteal3. Transverse branch of medal circumflex femoral 4. Transverse branch of lateral circumflex femoral

5 -perforating branches of profunda femoris artery:

• It is the series of anastomosis between the perforating branches of femoral artery. Superiorly they join the cuciate anastomosis and inferiorly they join the muscular branch of popliteal artery.

6 -Anastomosis around knee joint

• It is composed of:1. Genicular branches of popliteal artery2. Tibial recurrent branches of anterior tibial

artery3. Circumflex fibular artery from posterior tibial

aretry

7 -Anastomosis at the ankle and foot

1. Medial and Lateral malleolar networks2. Anastomosis between medial and lateral

plantar arteries
