Dilated phlebopathy

As dilated phlebopathy one calls the pathological enlargement of veins . In principle, it can occur anywhere, but in phlebology the term is mainly used to describe changes in the leg veins.

causes

Dilated phlebopathy occurs for no apparent reason and is therefore referred to as constitutional.

Disease value

Depending on the extent of the dilatation (enlargement), valve insufficiency occurs naturally. The incipient expansion is associated with a delayed valve closure. The moderate expansion also leads to a delayed valve closure, which, however, can no longer withstand pressure peaks. As soon as this can be proven, one speaks of an early incompetence of the vein segment. The advanced expansion makes the valve closure (see vein ) no longer possible. There is thus an insufficiency in the vein section concerned, e.g. B. Insufficiency of the great saphenous vein , if it affects the large superficial collecting vein , or guide vein insufficiency , if a deep vein (guide vein) of the leg is affected. The transitions are fluid. Beginning, medium and advanced do not mean absolute values ​​for the diameter, but are individually different.

In the early stages, dilated phlebopathy does not yet have a disease value of its own, but it should nevertheless be recognized in good time in order to prevent progression of the dilatation and the associated functional disorders.

Dilatation plus insufficiency already meet two of the three criteria of varicosis , which is classically associated with a tortuosity of the vessels. Seen in this way, dilated phlebopathy is a preliminary stage of varicosis.

Dilated phlebopathy is of particular importance in the deep venous system of the leg. There is no meandering and therefore no classic varicose veins possible. Here too, dilated phlebopathy is the forerunner of insufficiency, which in the deep venous system is referred to as leading venous insufficiency. It is far less noticeable than varicosis, but usually far more serious for those affected.
