Made this ppt in my first year at medicine for a group project on VENOUS DRAINAGE OF LOWER LIMB .. hope it can be of some help to you ! good luck :)

4. Veins of Lower Limb
Greater
Saphenous
Vein
Small
Saphenous
Vein
Femoral
Vein
Profunda
Femoris
Vein
Popliteal
Vein
Peroneal
Vein
Anterior
&
Posterior
Tibial Vein

5. Great saphenous vein
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 saphenous vein
originates from the lateral side
of the dorsal venous arch,
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.

7. Venous drainage of foot

8. Plantar digital veins connect with dorsal digital veins to form 4
plantar metatarsal veins which run proximally in the
intermetatarsal spaces and connect via perforating veins ,dorsal
veins.
A plantar venous arch is formed from which medial and later
plantar veins are formed.
The dorsal digital veins receive rami from plantar digital vein and
then form 4 dorsal metatarsal veins which unite to form dorsal
venous arch

12. MUSCULO-VENOUS PUMP
Contractions of large muscles within
closed facial compartments compress
the deeply placed veins and force blood
up the limb
The superficial veins are not subjected
to these high pressure compression forces.
Valves in perforators prevent high
pressure venous blood from being
forced outward into low pressure
superficial veins.
As the muscles within the closed facial compartments relax, venous
blood is sucked from superficial into deep veins

15. Venowave Innovation

16. Varicose veins
• Normal flow of blood in the venous system
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 condition produces 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.

21.  Surgical stripping
 Endovenous Thermal
Ablation (closure)
Sclerotherapy
 VNUS Closure (Also known
as endovenous radiofrequency
ablation)

23. HEAT ABLATION

26. Endovenous Radio Frequency
Ablation
Endovenous radio frequency ablation (Closure
procedure) is a minimally invasive.
In-office treatment alternative to surgical stripping of the
great saphenous vein.
The skin on the inside
of the knee is anesthetized
and a radiofrequency
catheter is inserted into the
damaged vein through a
needle stick in the skin.
The catheter delivers
Radiofrequency energy to the
vein wall causing it to heat. As the vein warms, it collapses
and seals shut.

27. 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 because blood clot that formed
in the vein can travel through the blood stream
and lodge in the lungs, blocking blood flow (
pulmonary embolism)

29. Presentation and Physical
Examination

30.  Not always possible to detect it because there may be no clinical
signs.
 Calf muscle tenderness, postoperative pyrexia, and limb swelling
can be helpful clues
Diagnosis-
Duplex Doppler sonography
Ascending venography.
• If DVT is confirmed, intravenous and oral anticoagulation are started to
prevent extension of the thrombus.
• Patients undergoing surgery are likely to develop DVT, so most surgical
patients are given specific prophylactic treatment which includes
anticoagulant injections and graduated stockings (to prevent deep
venous stasis and facilitate emptying of the deep veins).
Presentation and Diagnosis

33. BLOOD TEST: almost everyone with a
blood clot has elevated blood level of
naturally occurring clot dissolving substance
called D dimer. Not a conclusive test
ULTRASOUND:
CT SCAN

34. Inferior vena cava Filter : It maybe
inserted into the vena cava to prevent
pulmonary embolism
Thrombolysis: drugs or tPA
Anticoagulants : heparin or warfarin.
Blood thinners: Eliquis (was found to
be safer than any other blood thinner)
Graduated Compression stockings

36. Great Saphenous Vein in Coronary
Bypass Surgery
In patients with occlusive
coronary disease caused
by atherosclerosis, the
diseased arterial segment
can be bypasses by inserting
a graft consisting of a
portion of Great saphenous
vein.
Vein segment is reversed to prevent
obstruction by valves
