Purpose
Our exhibit will provide up to date information on mechanochemical endovenous ablation (MOCA), including latest data on efficacy and safety. Advantages and disadvantages over endovenous radiofrequency ablation (RFA) and endovenous laser therapy (EVLT) will be discussed.
Materials & Methods
Mechanochemical endovenous ablation (MOCA) is a relatively new procedure for the treatment of varicose veins, which utilizes a rotating wire along with infusion of a liquid sclerosant to induce scarring of the venous endothelium. The procedure eliminates the need for tumescent anesthesia as utilized by RFA and EVLT techniques, and therefore removes the risk for heat related injury to the adjacent nerves, blood vessels, muscle and skin. Several studies have also reported reduced postprocedural pain and shorter recovery times of MOCA compared to RFA. Long term efficacy of MOCA remains an active area of interest. Several studies have documented comparable efficacy rates to RFA and EVLT at 12 months, while several others have suggested lower efficacy rates of MOCA compared to RFA and EVLT.
Results
All articles evaluating efficacy of MOCA from June 2000 to June 2016 were included (n=12), with 4 studies having follow up time equal to or greater than 12 months. Number of subjects, follow up time, efficacy rates, and complication rates were evaluated. A total of 281 treated veins were followed up at 12 months with efficacy rates ranging between 88.2% and 95%. Since the definitions of success rates differed between studies, a discussion and comparison of the various definitions as well as differences in techniques and methods will be provided. Additional studies which assessed postprocedural pain levels and recovery times will be discussed.
Conclusions
Mechanochemical endovenous ablation is a safe, feasible and efficacious technique for treatment varicose veins. Although some initial studies demonstrate decreased efficacy of MOCA compared to EVLT and RFA, reduced post-procedural pain and earlier resumption of normal activities may justify its use. Prospective comparison studies are needed for further comparison to RFA and EVLT.
