Clarivein

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

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.

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

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

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.
