Automatic Sclerosant Injection Technique of Mechanochemical Ablation with ClariVein Using a Syringe Pump for the Treatment of Varicose Veins

Mechanochemical ablation (MOCA) is a non-thermal, non-tumescent technique for the treatment of incompetent saphenous vein. It is sometimes difficult to maintain consistency when simultaneously implementing wire rotation, sclerosant injection, and wire pullback. Here, we report a simple technique for achieving constant injection during MOCA with the help of a syringe pump; thus, the operator can focus on wire pullback only with convenience and consistency.
