2. Five top technical tips
1. Know the anatomy
2. Know as much as possible a patient history
3. Become comfortable with central vein evaluation
4. Watch for collateral veins
5. Focus on Doppler waveforms and symmetry
between the limbs

originates from the medial
side of the dorsal venous arch,
and then ascends up the
medial side of the leg, knee,
and thigh to connect with the
femoral vein just inferior to
the inguinal ligament
Small saphenousvein
originates from the lateral side
of the dorsal venousarch,
ascends up the posterior
surface of the leg, and then
penetrates deep fascia to join
the popliteal vein posterior to
the knee; proximal to the
knee, the popliteal vein
becomes the femoral vein.

10. COMMON DOPPLER TECHNIQUE / FINDINGS

27. DOPPLER US TECHNIQUE IN LL

48. A condition in which a blood clot forms in one or
more of the deep veins of the body, usually the
legs.
Can develop if one is sitting still for a long time,
such as when travelling by plane or if one has a
medical condition affecting the normal clotting of
blood.
Serious condition - becauseblood clot that formed
in the vein can travel through the blood stream
and lodge in the lungs, blocking blood flow
( Pulmonary Embolism)

108. VARICOSE VEIN

109. VARICOSE VEINS
• Normal flow of blood in the venous syste
depends upon the presence of competent
valves, which prevent reflux.
•Venous return is supplemented with contraction of
the muscles in the lower limb, which pump the blood
toward the heart.
•When venous valves become incompetent they
tend to place extra pressure on more
distal valves, which may also become
incompetent.
•This conditionproduces dilated tortuous superficial
veins (varicose veins) in the distribution of the great
(long) and small (short) saphenous venous systems.
Some individuals have a genetic predisposition to
developing varicose veins.
