In the case of venous insufficiency, the venous valves no longer close properly. The venous valves act like valves and allow the blood to flow back to the heart against the natural force of gravity. If this system is permanently impaired, venous insufficiency occurs. Blood builds up in the legs over time. Fluid leaks out of the surrounding tissue, which means that the skin receives fewer nutrients. Phlebologists refer to the condition as chronic venous insufficiency if it has been present for a long time and
the skin is already damaged.
What are the first symptoms of venous insufficiency?
In the beginning, tired legs usually appear – for example at night or after prolonged standing or sitting. A slight swelling of the ankles, which can also occur in the evening or on hot summer days, is an initial indication. When the veins become weaker, cramps in the legs or “restless” legs can be a sign of this.
Initially, venous insufficiency becomes visible through spider veins. If a brownish discoloration appears on the lower legs or ankles, venous insufficiency is already present. In couperose, this discoloration is located in the cheek, nose and chin regions.
Ulcus cruris, colloquially known as “open leg”, is the worst condition of the disease, which is associated with poorly healing or non-healing wounds on the lower leg, particularly on the inner ankle. This sign marks the end of a sequence of precursors that develop over the course of several years.
