Profound consequences
If the superficial veins no longer fulfill their task, the deep veins have to take over the transport of blood back to the heart. This extra work means that sooner or later their valve system is at risk of irreparable damage due to overload. However, a valve disorder in the deep venous system can no longer be treated surgically. Instead, chronic venous insufficiency (CVI) develops with serious and permanent consequences. Typical symptoms of CVI are pain after standing for a long time, heavy and tired or restless legs, itching, nocturnal calf cramps or a feeling of pressure and tension.
