Superficial vein failure
Deep
valve failure is very uncommon in humans.
Much more commonly, the valves in the
SUPERFICIAL veins stop working and fail.
In this case, during movement, the blood is
pumped up both deep and superficial veins during muscles contraction - ie:
PUMPING the leg, just as in the normal leg.
When the leg RELAXES, the pumping stops and
gravity causes the blood to flow backwards down both deep and superficial
vein systems. The working valves in
the deep system stop any back flow down the deep veins.
However, in this case, the valves in the
SUPERFICIAL veins are not working. So in this situation, blood falls back
down the superficial veins that have lost their valves.
As you can see, this actually has a very
similar end result to the valves not working in the deep system.
Despite this clear parallel, it is the fact
that this similarlity has not be recognised and understood by doctors and
nurses that has resulted in the misunderstanding has occurred over the
last 100 years that has meant that leg ulcers, skin changes at the ankle
and varicose veins have been treated so badly.
Unfortunately, although increasing numbers
of specialists ar enow starting to understand this, a very large number of
doctors and nurses continue to remian ignorant of this mechanism of
inflammation caused by valve failre, resulting in the poor treatment of
leg ulcers, venous eczema and skin damage that happens because of the
valve failure. The blood falling the
wrong way down the veins is said to be "refluxing". Hence these conditions
are said to be due to "venous reflux disease".
