Mechanochemical Ablation (MOCA) for Chronic Venous Disease

MOCA is a non-thermal non-tumescent technique to ablate incompetent superficial veins of the lower limb. The technique uses a dual injury mechanism that combines mechanical disruption of the intima with chemical endovenous ablation by injecting a sclerosing agent. Several RCT trials demonstrate that MOCA is a safe and effective technique compared to EVTA. at the early follow up was proven; long term follow up data seems to be less encouraging as an RCT revealed a statistically significantly lower GSV occlusion rate of 80% 3 years after MOCA and a strong association was found between recanalization at 3 years and the pre-operative GSV diameter.
