MOCA Versus RFA in the Treatment of Primary Great Saphenous Varicose Veins (MARADONA)

This study is ongoing, but not recruiting participants.

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.

Primary Outcome Measures:
  • Occlusion rate [ Time Frame: 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 [ Time Frame: two weeks ]
    Pain during the procedure will be compared between treatments using the VAS score

  • Complications [ Time Frame: 30 days ]
    Complication at day 30 will be compared between treatments.

  • Procedure duration [ Time Frame: 30 days ]
    The duration of the procedures will be compared

  • Costs of both treatments [ Time Frame: 1 year ]
    The total costs of both treatments will be compared

  • Health status [ Time Frame: 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 [ Time Frame: 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 [ Time Frame: 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 [ Time Frame: 30 days ]
    Time until daily activities and or work can be resumed (measured in days)
