Origin of the chronic venous disease

Malfunction of the venous system can be primary (in almost 90% of cases) or secondary (approximately 10% of cases of chronic venous insufficiency). Sooner or later, it leads to progressive chronic venous disease (CVD), which affects between 11 to 24% of the population in industrialised countries, with a clear predominance among women (male-female ratio = 1/3).


It is called primary when the impairment is not a consequence of another disease. The precise origin of this impairment is unknown but experience has shown that certain factors make it possible to define a population at risk.

Conversely, the CVD is termed secondary when it is consecutive to another disease, primarily deep vein thrombosis (DVT). This is then called post-thrombotic syndrome or disease (also called post-phlebitic syndrome).(expert's view by Jean-Patrick Benigni, MD, General Secretary of the French Society of Phlebology, Paris - France...)  (read more...)
