ClariVein mechanochemical ablation: background and procedural details

Abstract

Objectives: The 2 primary objectives of this publication are to provide a practical step-by-step procedure for the ClariVein system and a focused literature review of endovenous ablation.

Materials and methods: The ClariVein system is the first venous ablation technique to employ a hybrid (dual-injury) technique built into 1 catheter-based delivery system. Endomechanical abrasion is produced by the tip of the catheter's rotating wire (mechanical component); and endovenous chemical ablation (EVCA) is via simultaneous injection of sclerosant over the rotating wire (chemical component). The author is an early adopter of this technique and via experience has developed a detailed step-by-step protocol.

Discussion: To date, there have been 2 pivotal clinical studies published using the ClariVein system. These data are compared with the results using other methods of endovenous ablation.

Conclusions: The ClariVein system is an exciting addition to the phlebologist's toolbox and has the potential to become a first-line treatment.
