MARADONA: MOCA Versus RFA in the Treatment of Primary Great Saphenous Varicose Veins
Study Details
Study Description
Brief Summary
The newly developed Mechanochemical Endovenous Ablation (MOCA) device uses a technique that combines mechanical endothelial damage using a rotating wire with the infusion of a liquid sclerosant. Heating of the vein and tumescent anesthesia are not required; only local anesthesia is utilized at the insertion site. Previously we showed that endovenous MOCA, using polidocanol, is feasible and safe in the treatment of great spahenous vein (GSV) incompetence. However, larger studies with a prolonged follow-up to prove the efficacy of this technique in terms of obliteration rates are lacking. This randomized trial was designed to compare occlusion rate, post-operative pain and complications between radiofrequency ablation (RFA: the current treatment for GSV incompetence) en MOCA.

Outcome Measures
Primary Outcome Measures
- Occlusion rate [up to 5 years]
Occlusion rates between treatments will be compared at mentioned time points (both technical and clinical success)
Secondary Outcome Measures
- Per-procedural pain score [two weeks]
Pain during the procedure will be compared between treatments using the VAS score
- Complications [30 days]
Complication at day 30 will be compared between treatments.
- Procedure duration [30 days]
The duration of the procedures will be compared
- Costs of both treatments [1 year]
The total costs of both treatments will be compared
- Health status [1 year, 5 years]
Using the RAND 36-Item short From Health Survey (SF36) the general health status will be compared between treatments at various time points as specified by the protocol.
- Post procedural pain score [two weeks]
Pain during the the first two weeks after the procedure will be compared between treatments using the VAS score
- Disease related quality of life [1 year, 5 years]
Using the Aberdeen Varicose Vein Questionnaire (AVVQ)the disease related quality of life will be compared between treatments at various time points as specified by the protocol.
Other Outcome Measures
- Recovery time [30 days]
Time until daily activities and or work can be resumed (measured in days)
