DefinitionThis section has been translated automatically.

Mechano-chemical, non-thermal endoluminal method for the therapy of stem varicosis

EffectsThis section has been translated automatically.

A vasospasm (contraction) is produced by a very fast rotating wire with a specially angled tip inside the catheter, which strikes the inner wall of the vessel. At the same time a liquid sclerosing agent is injected. The very fast rotating tip also causes the sclerosing agent to swirl and thus to make even contact with the entire inner vein wall and sclerose it.

According to the current study situation, short-term occlusion rates of approx. 90%. Medium and long-term results are lacking.

IndicationThis section has been translated automatically.

Therapy of a truncal varicosis of V. saphena magna and V. saphena parva

ImplementationThis section has been translated automatically.

Duplex controlled puncture of the vein to be treated at the lower point of insufficiency

Insertion of an indwelling venous cannula 18G

Insertion and duplex controlled positioning of the catheter in the vein

Starting the rotation and inserting the sclerosing agent via the handpiece

Undesirable effectsThis section has been translated automatically.

The same adverse effects are found as with sclerotherapy alone. According to our own experience more frequent vasovagal reactions of patients with hypotension and bradycardia.
