One particular form should be noted: the "red sock syndrome". This affects women over the
age of 45 with very fine, very superficial red varicosities on the legs, ankles and the back of
the foot. No varicose veins are found.
The difficulty of catheterising these micro-vessels limits the therapeutic options. Recidivism
frequently occurs
Matting
Small angiomatous, circumscribed and congestive, they are secondary to an aggression, an
external or iatrogenic traumatism (contusion) caused by :
Stripping
From traumatising surgery
From a major hematoma
From the persistence of an accessory saphenous vein or an incontinent
perforator
From phlebectomy: generally if the varicose vein is left in place
From sclerosis: sclerosis nearby with an excessive concentration or too much
injected
An area predisposed to varicosity is probable. Biological or hemorheological factors could play
a role.
Varicosities fed by drainage venules
Major category. An Australian study by Thibault showed that 25% of symptomatic varicosities
were associated with major sources of valvulary venous insufficiency. These varicosities are
often found in groups.
Hemodynamic Reflux
Reflux is responsible for these varicosities, which appear after the superficial venous network
is subjected to pressure. From a physiopathological standpoint, the transmission of pressure
from the reticular veins to the venules probably results in their dilation and transforms them
into telangiectasis and venulectasis.
Thanks to micro-phlebography, it has been possible to determine the origin of the reflux.
In 30% of cases we find the deep venous network isolated.
In 20% the superficial venous network.
And in 50% of cases, both networks.
Finding these reticular drainage veins is not always easy. It requires careful examination.
Clinical examination should be able to find a reticular venule. The inferior member should be
observed in the centripetal direction.
It is also possible to use cartography of the drainage zones to find the root causes of
telangiectases.
The different zones are:
