Surface anatomy of arteries and veins of lower limb femoral Artery
SURFACE ANATOMY OF ARTERIES
AND VEINS OF LOWER LIMB
Corresponds to upper two thirds of a line joining following two points.
- a point midway between anterior superior iliac spine and pubic symphysis.
- it lies at lower end of cord-like tendon of Adductor Magnus.
- Tendon can be felt in a shallow groove just behind prominence of vastus medialis
when thigh is semiflexed
,abducted and laterally rotated.
Surface Anatomy Of Femoral Artery
- Upper one third of line represents upper half of artery lying in femoral triangle.
- Middle third of line represents lower half of artery lying in adductor canal.
- Lower one third of line represents descending genicular and saphenous branches of artery.
- First mark femoral artery.
- Profunda artery is then marked by joining following two points
on femoral artery:
(a) A point 3.5cm below mid inguinal point.
(b)A second point 10cm below mid inguinal point.
Artery is slightly convex laterally in upper part.
It is marked by joining following points:
A point at junction of middle
and lower thirds of thigh
medial to midline on back of limb.
A second point on midline of back of knee.
A third point on midline of back of leg at level of tibial tuberosity.
It is marked by joining following two points:
- 2.5cm below medial side of head of fibula.
- midway between two malleoli.
- The artery passes downwards and slightly medially.
Posterior Tibial Artery
It is marked by following two points:
- Midline of back of calf at level of tibial tuberosity.
- midway between medial malleolus and tendo calcaneus.
Dorsalis Pedis Artery
It is marked by
joining following two points
- Midway between two malleoli.
- At proximal end of first intermetatarsal space.
Its marking is same as that of femoral artery, except:
Upper point is taken 1cm medial to mid inguinal point.
Lower point 1cm lateral to adductor tubercle.
Vein is medial to artery at upper end.
Posterior to it in middle.
Lateral to it at lower end.
Marked by joining following points
- Dorsum of foot at medial end of dorsal venous arch.
- Anterior surface of medial malleolus.
- Medial border of tibia at junction of upper two third and lower one third of leg.
- Adductor tuberecle.
- Just below centre of saphenous opening.
