clarivein. Mechanochemical ablation
It is an endovenous treatment performed with a catheter and designed to occlude the insufficient saphenous axis.
CLARIVEN
This is the latest technique incorporated into the therapeutic arsenal of our practice.
It is a device that is placed inside the vein by puncture (with a minimal amount of local anesthesia). Once placed by echo-doppler control in the ideal place, the catheter is withdrawn, which rotates rapidly, while a sclerosing drug is injected into the vein.
The effect, a mixture of mechanical endothelial injury from the rotating effect of the catheter and a mixture of chemical injury from the sclerosing drug, produces occlusion and secondary fibrosis of the treated vein.
Compared to other techniques that take a longer time, such as endovenous laser or radiofrequency, Clariven has two advantages:
- the minimum use of local anesthesia (minimizes pain so that not even light sedation is usually necessary) and postoperative discomfort that is even less, if possible, than with other procedures.
As a negative aspect, it should be noted that with it we cannot effectively treat large caliber saphenous veins greater than 2 centimeters in diameter.
