ClariVein mechanochemical ablation: background and procedural details.

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.
