Chronic Venous Insufficiency (CVI) Stage III
(Ulcus cruris)

Veins are blood vessels which pump the „used“ blood from the body back to the heart. They serve as collector and resevoir vessels and contain approx. 85 percent of the total body's own blood volume. In order to comply with their function of accumulation, veins are less muscular and extremely elastic, in order to stretch and yield according to the pressure of the blood.

With regard to limbs, we distinguish between a deep and a superficial venous system. The superficial venous system collects the blood from the skin and carries it into the depth via connecting veins. The deep venous system then pumps the blood towards the heart. This venous back flow into the leg area can be carried out in two different ways: firstly by pressure onto the sole of the foot, followed by a movement in the ankle joint and especially by the calf muscles which pressures the veins in the depth. The valves prevent the backflow of blood into the legs; due these valves there is only one direction for the blood left: towards the heart.

Secondly: The blood is pulled towards the heart, achieved by its pumping capacity, however, also by the pressure change in the chest due to breathing and due to pulsation of the adjoining arteries.

Venous diseases

A constant pressure onto the venous valves - for example due to predominantly sedentary or standing activities, predisposition, pregnancies or other factors - results in a dilatation of the leg veins. As a result the venous valves do not close anymore and the blood pools in the legs. These enlarged veins clearly emerge as "varicose veins". Varicose veins often tend to inflame and, due to its low flow the blood may agglutinate and block the veins (thrombosis). This again may lead to a pulmonary embolism, a deadly threat, if happening in one of the deep guide veins.

Should the disease persist, the venous system can no longer fulfill its intended functions and becomes "chronically isufficient". The chronic venous insufficiency (CVI) is divided into three clinical stages:

The treatment of Ulcus cruris depends on the cause. As often additional diseases are present as well, the treatment is usually very time-consuming and requires a close application of various measures. This is why an inpatient accommodation becomes necessary in most of the cases. The Lympho-Opt clinic has decades of experience in the field of CVI plus the corresponding instrumental equipment.
