THE MECHANISM OF ACTION
The mechane is of endovenous laser therapy is based on the thermal destruction of venous tissue. In this process, the laser radiation is transferred via the fiber to the dysfunctional segment inside the vein. Within the penetration area of the laser beam, heat is generated by direct absorption of laser energy and the inside vein wall intentionally irreversible damaged. The vein closes, hardens and completely disappears within a few month (6 – 9) or is reduced, respectively, rebuilt to connective tissue by the body.
Among endovenous thermo ablation processes, EVLT offers following advantages in comparison to radio frequency ablation:
• Access via puncture due to small fiber dimension
• Focused and specific heat input into the vessel wall
• Lower heat input into surrounding tissue
• Fewer pain during surgery
• Fewer postoperative pain
• Clearly cheaper applicators
• Enhanced fiber positioning based on aiming beam function
