Venous insufficiency is a circulatory disorder in the veins of the lower limbs.
The disease is characterized by an alteration of the valves that prevent the backflow of the blood away from the heart. When these valves fail to close properly, the blood flows downwards, especially in small veins: this is called venous stasis. This blood stagnation leads to an overall weakening of the vein wall.
When the peripheral veins, by their dilatation, lose their ability to raise blood to the heart, the resulting hyperpressure damages the surrounding tissues. Under varicose conditions, symptoms such as heaviness, pain, night cramps, itching are observed. In the absence of treatment, and depending on the course of the disease, complications may result: pigmentation, weakening of the skin resulting in ulcers, and more rarely, variceal bleeding and phlebitis (venous thrombosis).
Since varicose veins cannot be “repaired”, the treatment techniques aim at removing or neutralizing them. , Thanks to the central veins, blood circulation is still maintained alternately to the peripheral veins.
Venous disease is a health problem that affects a large part of the population. About 20-25% of women and 10-15% of men suffer from "visible" varicose veins.
Often mild in its infancy, venous disease evolves insidiously. The initial symptoms are often diffuse in nature: difficult to express, they nevertheless have a negative impact on the quality of life of those who suffer from it.
The clinical classification CEAP highlights the evolution of the different stages of the disease: varicose veins and varicose ulcers require appropriate medical interventions and care.
