Mechano-Chemical Endovenous Ablation of Great Saphenous Vein Insufficiency: Two-Year Results

Objective: The objective of this study is to evaluate the reliability and 2-year results of ClariVein® device used in mechanochemical endovenous ablation of great saphenous vein (GSV). Material and Methods: In our clinic, 63 patients with GSV insufficiency had been treated using ClariVein® device and polidocanol for 2 years. Both legs were treated in 10 of these patients. The anatomical and clinic success were assessed by Doppler ultrasonography 6 months, 1 year, and 2 years later. Results: The implementation success rate of the technique was 98%. The anatomical success was found as 94% at the end of 6 months, 95% at the end of 1 year, and 95% at the end of 2 years. The venous clinic severity score was found as 3.2 (interquartile range: IQR: 2-6) after 6 months, 1.2 (IQR: 1-3, p<0.001) after 1 year, and 1.1 (IQR: 1-2, p<0.001) after 2 years. No complications developed in any of the patients. Conclusion: ClariVein® is a simple, reliable, and efficient treatment method for GSV insufficiency. In 2-year follow-up, the anatomical success rate was found as 95%, and no major complications were observed.
