Varicose veins are a common condition: they are mostly associated with incompetence of Great and Small Saphenous Vein.
Minimally invasive techniques have been utilized over the last 13 years; they involve percutaneous access, perivenous tumescent anesthesia, some form of ablation, short procedure time, good safety and efficacy. Most endovenous ablation techniques are based on heat delivery to the vein wall.
The Mechanochemical Ablation (MOCA) using the ClariVein® device has been developed to minimize the negative aspects of endothermal ablation and ultrasound-guided sclerotherapy.
This method utilizes a rotating wire within the lumen of the vein: the mechanical injury to the venous inner wall is associated with simultaneous infusion of a liquid sclerosant through the same catheter; no tumescent anesthesia is needed.
It’s an office-based procedure and normal daily activities can immediately be resumed.
Venous occlusion rates are comparable to those achieved with endothermal methods.
